You can set the NWA/WAC to operate in either standalone AP or managed AP mode. When the
NWA/WAC is in standalone AP mode, it can serve as a normal AP, as an RF monitor to search for
rouge APs to help eliminate network threats (if it supports monitor mode and rogue APs detection),
or even as a root AP or a wireless repeater to establish wireless links with other APs in a WDS
(Wireless Distribution System). A WDS is a wireless connection between two or more APs.
Your NWA/WAC’s business-class reliability, SMB features, and centralized wireless management
make it ideally suited for advanced service delivery in mission-critical networks. It uses Multiple
BSSID and VLAN to provide simultaneous independent virtual APs. Additionally, innovations in
roaming technology and QoS features eliminate voice call disruptions.
The NWA/WAC controls network access with Media Access Control (MAC) address filtering, and
rogue Access Point (AP) detection. It also provides a high level of network traffic security,
supporting IEEE 802.1x, Wi-Fi Protected Access 2 and Wired Equivalent Privacy (WEP) data
encryption.
Your NWA/WAC is easy to install, configure and use. The embedded Web-based configurator
enables simple, straightforward management and maintenance. See the Quick Start Guide for how
to make hardware connections.
1.1.1 Management Mode
The NWA/WAC is a unified AP and can work either in standalone AP mode or in managed AP mode.
If the NWA/WAC and a ZyXEL AP controller, such as the NXC2500 or NXC5500, are in the same
subnet, it will be managed by the controller automatically.
An AP controller uses Control And Provisioning of Wireless Access Points (CAPWAP, see RFC 5415)
to discover and configure multiple managed APs.
To set the NWA/WAC to be managed by an AP controller in a different subnet or change between
management modes, use the AC (AP Controller) Discovery screen (see Section 5.4 on page 63).

When the NWA/WAC is in standalone AP mode and connects to a DHCP server, it uses the IP
address assigned by the DHCP server. Otherwise, the NWA/WAC uses the default static
management IP address (192.168.1.2). You can use the AC Discovery screen to have the NWA/
WAC work as a managed AP.
NWA5000 / WAC6500 Series User’s Guide
12
Chapter 1 Introduction
When the NWA/WAC is in managed AP mode, it acts as a DHCP client and obtains an IP address
from the AP controller. It can be configured ONLY by the AP controller. To change the NWA/WAC
back to standalone AP mode, use the Reset button to restore the default configuration.
Alternatively, you need to check the AP controller for the NWA/WAC’s IP address and use FTP to
upload the default configuration file at conf/system-default.conf to the NWA/WAC and reboot the
device.
1.1.2 MBSSID
A Basic Service Set (BSS) is the set of devices forming a single wireless network (usually an access
point and one or more wireless clients). The Service Set IDentifier (SSID) is the name of a BSS. In
Multiple BSS (MBSSID) mode, the NWA/WAC provides multiple virtual APs, each forming its own
BSS and using its own individual SSID profile.
You can configure multiple SSID profiles, and have all of them active at any one time.
You can assign different wireless and security settings to each SSID profile. This allows you to
compartmentalize groups of users, set varying access privileges, and prioritize network traffic to
and from certain BSSs.
To the wireless clients in the network, each SSID appears to be a different access point. As in any
wireless network, clients can associate only with the SSIDs for which they have the correct security
settings.
For example, you might want to set up a wireless network in your office where Internet telephony
(VoIP) users have priority. You also want a regular wireless network for standard users, as well as a
‘guest’ wireless network for visitors. In the following figure, VoIP_SSID users have QoS priority,
SSID01 is the wireless network for standard users, and Guest_SSID is the wireless network for
guest users. In this example, the guest user is forbidden access to the wired Land Area Network
(LAN) behind the AP and can access only the Internet.

1.1.3 Dual-Radio
Some of the NWA/WAC models are equipped with dual wireless radios. This means you can
configure two different wireless networks to operate simultaneously.
Note: A different channel should be configured for each WLAN interface to reduce the
effects of radio interference.
You could use the 2.4 GHz band for regular Internet surfing and downloading while using the 5 GHz
band for time sensitive traffic like high-definition video, music, and gaming.

1.1.4 Root AP
In Root AP mode, the NWA/WAC (Z) can act as the root AP in a wireless network and also allow
repeaters (X and Y) to extend the range of its wireless network at the same time. In the figure
below, both clients A, B and C can access the wired network through the root AP.
Figure 3 Root AP Application
On the NWA/WAC in Root AP mode, you can have multiple SSIDs active for regular wireless
connections and one SSID for the connection with a repeater (repeater SSID). Wireless clients can
NWA5000 / WAC6500 Series User’s Guide
15
Chapter 1 Introduction
use either SSID to associate with the NWA/WAC in Root AP mode. A repeater must use the repeater
SSID to connect to the NWA/WAC in Root AP mode.
When the NWA/WAC is in Root AP mode, repeater security between the NWA/WAC and other
repeater is independent of the security between the wireless clients and the AP or repeater. When
repeater security is enabled, both APs and repeaters must use the same pre-shared key. See
Section 6.2 on page 66 and Section 10.2 on page 106 for more details.
Unless specified, the term “security settings” refers to the traffic between the wireless clients and
the AP. At the time of writing, repeater security is compatible with the NWA/WAC only.
1.1.5 Repeater
The NWA/WAC can act as a wireless network repeater to extend a root AP’s wireless network range,
and also establish wireless connections with wireless clients.
Using Repeater mode, your NWA/WAC can extend the range of the WLAN. In the figure below, the
NWA/WAC in Repeater mode (Z) has a wireless connection to the NWA/WAC in Root AP mode (X)
which is connected to a wired network and also has a wireless connection to another NWA/WAC in
Repeater mode (Y) at the same time. Z and Y act as repeaters that forward traffic between
associated wireless clients and the wired LAN. Clients A and B access the AP and the wired network
behind the AP through repeaters Z and Y.
Figure 4 Repeater Application
When the NWA/WAC is in Repeater mode, repeater security between the NWA/WAC and other
repeater is independent of the security between the wireless clients and the AP or repeater. When
repeater security is enabled, both APs and repeaters must use the same pre-shared key. See
Section 6.2 on page 66 and Section 10.2 on page 106 for more details.
Once the security settings of peer sides match one another, the connection between devices is
made.

1.2 Ways to Manage the NWA/WAC
You can use the following ways to manage the NWA/WAC.
Web Configurator
The Web Configurator allows easy NWA/WAC setup and management using an Internet browser.
This User’s Guide provides information about the Web Configurator.
Command-Line Interface (CLI)
The CLI allows you to use text-based commands to configure the NWA/WAC. You can access it
using remote management (for example, SSH or Telnet). See the Command Reference Guide for
more information.
File Transfer Protocol (FTP)
This protocol can be used for firmware upgrades and configuration backup and restore.
Simple Network Management Protocol (SNMP)
The NWA/WAC can be monitored by an SNMP manager. See the SNMP chapter in this User’s Guide.
1.3 Good Habits for Managing the NWA/WAC
Do the following things regularly to make the NWA/WAC more secure and to manage it more
effectively.
• Change the password often. Use a password that’s not easy to guess and that consists of
different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier
working configuration may be useful if the device becomes unstable or even crashes. If you
forget your password, you will have to reset the NWA/WAC to its factory default settings. If you
backed up an earlier configuration file, you won’t have to totally re-configure the NWA/WAC; you
can simply restore your last configuration.
1.4 Hardware Connections
See your Quick Start Guide for information on making hardware connections.

1.5.2 Phone Port
Connect a digital telephone to the RJ-45 PHONE port at the bottom of the NWA to forward voice
traffic to/from the telephone switchboard that is connected to the RJ-45 PHONE port on the back of
the NWA. The NWA does not support VoIP (Voice over Internet Protocol) and the PHONE port is
NOT for making calls over the regular networking network (PSTN), either.
1.5.3 Console Port
To use the CLI commands to configure the NWA, connect an RJ-45-to-DB-9 cable to the PHONE
port at the bottom of the NWA.

1.7 Starting and Stopping the NWA/WAC
Here are some of the ways to start and stop the NWA/WAC.
Always use Maintenance > Shutdown or the shutdown command before
you turn off the NWA/WAC or remove the power. Not doing so can cause
the firmware to become corrupt.
Table 9 Starting and Stopping the NWA/WAC
METHOD
DESCRIPTION
Turning on the power
A cold start occurs when you turn on the power to the NWA/WAC. The NWA/WAC
powers up, checks the hardware, and starts the system processes.
Rebooting the NWA/
WAC
A warm start (without powering down and powering up again) occurs when you use
the Reboot button in the Reboot screen or when you use the reboot command. The
NWA/WAC writes all cached data to the local storage, stops the system processes,
and then does a warm start.
Using the RESET
button
If you press the RESET button on the back of the NWA/WAC, the NWA/WAC sets the
configuration to its default values and then reboots. See Section 19.6 on page 187 for
more information.
Clicking
Maintenance >
Shutdown >
Shutdown or using
the shutdown
command
Clicking Maintenance > Shutdown > Shutdown or using the shutdown command
writes all cached data to the local storage and stops the system processes. Wait for
the device to shut down and then manually turn off or remove the power. It does not
turn off the power.
Disconnecting the
power
Power off occurs when you turn off the power to the NWA/WAC. The NWA/WAC
simply turns off. It does not stop the system processes or write cached data to local
storage.
The NWA/WAC does not stop or start the system processes when you apply configuration files or
run shell scripts although you may temporarily lose access to network resources.

Network
5.1 Overview
This chapter describes how you can configure the management IP address and VLAN settings of
your NWA/WAC.
The Internet Protocol (IP) address identifies a device on a network. Every networking device
(including computers, servers, routers, printers, etc.) needs an IP address to communicate across
the network. These networking devices are also known as hosts.
Figure 28 IP Setup
The figure above illustrates one possible setup of your NWA/WAC. The gateway IP address is
192.168.1.1 and the managed IP address of the NWA/WAC is 192.168.1.2 (default), but if the
NWA/WAC is assigned an IP address by a DHCP server, the default (192.168.1.2) will not be used.
The gateway and the NWA/WAC must belong in the same IP subnet to be able to communicate with
each other.
5.1.1 Management Mode
This discusses using the NWA/WAC in management mode, which determines whether the NWA/
WAC is used in its standalone mode, or as part of a Control And Provisioning of Wireless Access
Points (CAPWAP) network.
About CAPWAP
The NWA/WAC supports CAPWAP. This is ZyXEL’s implementation of the CAPWAP protocol (RFC
5415).
The CAPWAP dataflow is protected by Datagram Transport Layer Security (DTLS).
The following figure illustrates a CAPWAP wireless network. You (U) configure the AP controller (C),
which then automatically updates the configurations of the managed APs (M1 ~ M4).
NWA5000 / WAC6500 Series User’s Guide
57
Chapter 5 Network
Figure 29 CAPWAP Network Example
Note: The NWA/WAC can be a standalone AP (default), or a CAPWAP managed AP.
CAPWAP Discovery and Management
The link between CAPWAP-enabled access points proceeds as follows:
An AP in managed AP mode joins a wired network (receives a dynamic IP address).
The AP sends out a discovery request, looking for a CAPWAP AP controller.
If there is an AP controller on the network, it receives the discovery request. If the AP controller is
in Manual mode it adds the details of the AP to its Unmanaged Access Points list, and you
decide which available APs to manage. If the AP is in Always Accept mode, it automatically adds
the AP to its Managed Access Points list and provides the managed AP with default configuration
information, as well as securely transmitting the DTLS pre-shared key. The managed AP is ready for
association with wireless clients.
Managed AP Finds the Controller
A managed NWA/WAC can find the controller in one of the following ways:
• Manually specify the controller’s IP address in the Web Configurator’s AC (AP Controller)
Discovery screen.
• Get the controller’s IP address from a DHCP server with the controller’s IP address configured as
option 138.
• Get the controller’s IP address from a DNS server SRV (Service) record.
• Broadcasting to discover the controller within the broadcast domain.
Note: The AP controller needs to have a static IP address. If it is a DHCP client, set the
DHCP server to reserve an IP address for the AP controller.
NWA5000 / WAC6500 Series User’s Guide

Chapter 5 Network
CAPWAP and IP Subnets
By default, CAPWAP works only between devices with IP addresses in the same subnet.
However, you can configure CAPWAP to operate between devices with IP addresses in different
subnets by doing the following.
• Activate DHCP. Your network’s DHCP server must support option 138 defined in RFC 5415.
• Configure DHCP option 138 with the IP address of the CAPWAP AP controller on your network.
DHCP Option 138 allows the CAPWAP management request (from the AP in managed AP mode) to
reach the AP controller in a different subnet, as shown in the following figure.
Figure 30 CAPWAP and DHCP Option 138
Notes on CAPWAP
This section lists some additional features of ZyXEL’s implementation of the CAPWAP protocol.
• When the AP controller uses its internal Remote Authentication Dial In User Service (RADIUS)
server, managed APs also use the AP controller’s authentication server to authenticate wireless
clients.
• If a managed AP’s link to the AP controller is broken, the managed AP continues to use the
wireless settings with which it was last provided.

Chapter 5 Network
In the figure above, to access and manage the NWA/WAC from computer A, the NWA/WAC and
switch B’s ports to which computer A and the NWA/WAC are connected should be in the same
VLAN.
A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same
group(s); the traffic must first go through a router.
VLAN also increases network performance by limiting broadcasts to a smaller and more
manageable logical broadcast domain. In traditional switched environments, all broadcast packets
go to each and every individual port. With VLAN, all broadcasts are confined to a specific broadcast
domain.
IEEE 802.1Q Tag
The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to identify the VLAN
membership of a frame across bridges. A VLAN tag includes the 12-bit VLAN ID and 3-bit user
priority. The VLAN ID associates a frame with a specific VLAN and provides the information that
devices need to process the frame across the network.

6.1 Overview
This chapter discusses how to configure the wireless network settings in your NWA/WAC.
The following figure provides an example of a wireless network.
Figure 35 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network, devices A and B are
called wireless clients. The wireless clients use the access point (AP) to interact with other devices
(such as the printer) or with the Internet. Your NWA/WAC is the AP.
6.1.1 What You Can Do in this Chapter
• The AP Management screen (Section 6.2 on page 66) manages the NWA/WAC’s general
wireless settings.
• The MON Mode screen (Section 6.3 on page 69) allows you to assign APs either to the rogue AP
list or the friendly AP list.
• The Load Balancing screen (Section 6.4 on page 71) configures network traffic load balancing
between the APs and the NWA/WAC.
• The DCS screen (Section 6.5 on page 74) configures dynamic radio channel selection.

6.1.2 What You Need to Know
The following terms and concepts may help as you read this chapter.
Station / Wireless Client
A station or wireless client is any wireless-capable device that can connect to an AP using a wireless
signal.
Dynamic Channel Selection (DCS)
Dynamic Channel Selection (DCS) is a feature that allows an AP to automatically select the radio
channel upon which it broadcasts by scanning the area around it and determining what channels
are currently being used by other devices.
Load Balancing (Wireless)
Wireless load balancing is the process where you limit the number of connections allowed on an
wireless access point (AP) or you limit the amount of wireless traffic transmitted and received on it
so the AP does not become overloaded.

If you select By Station Number or By Traffic Level, once the threshold is crossed
(either the maximum station numbers or with network traffic), the NWA/WAC delays
association request and authentication request packets from any new station that
attempts to make a connection. This allows the station to automatically attempt to
connect to another, less burdened AP if one is available.

This function is enabled by default and the disassociation priority is always Signal
Strength when you set Mode to By Smart Classroom.
Select this option to disassociate wireless clients connected to the AP when it becomes
overloaded. If you do not enable this option, then the AP simply delays the connection
until it can afford the bandwidth it requires, or it transfers the connection to another AP
within its broadcast radius.
The disassociation priority is determined automatically by the NWA/WAC and is as
follows:
•
•
Idle Timeout - Devices that have been idle the longest will be kicked first. If none
of the connected devices are idle, then the priority shifts to Signal Strength.
Signal Strength - Devices with the weakest signal strength will be kicked first.
Note: If you enable this function, you should ensure that there are multiple APs within the
broadcast radius that can accept any rejected or kicked wireless clients; otherwise,
a wireless client attempting to connect to an overloaded AP will be disassociated
permanently and never be allowed to connect.

6.4.1 Disassociating and Delaying Connections
When your AP becomes overloaded, there are two basic responses it can take. The first one is to
“delay” a client connection. This means that the AP withholds the connection until the data transfer
throughput is lowered or the client connection is picked up by another AP. If the client is picked up
by another AP then the original AP cannot resume the connection.
NWA5000 / WAC6500 Series User’s Guide
72
Chapter 6 Wireless
For example, here the AP has a balanced bandwidth allotment of 6 Mbps. If laptop R connects and
it pushes the AP over its allotment, say to 7 Mbps, then the AP delays the red laptop’s connection
until it can afford the bandwidth or the laptop is picked up by a different AP with bandwidth to
spare.
Figure 40 Delaying a Connection
The second response your AP can take is to kick the connections that are pushing it over its
balanced bandwidth allotment.
Figure 41 Kicking a Connection
Connections are kicked based on either idle timeout or signal strength. The NWA/WAC first looks
to see which devices have been idle the longest, then starts kicking them in order of highest idle
time. If no connections are idle, the next criteria the NWA/WAC analyzes is signal strength. Devices
with the weakest signal strength are kicked first.

6.6 Technical Reference
The following section contains additional technical information about the features described in this
chapter.
Dynamic Channel Selection
When numerous APs broadcast within a given area, they introduce the possibility of heightened
radio interference, especially if some or all of them are broadcasting on the same radio channel. If
the interference becomes too great, then the network administrator must open his AP configuration
options and manually change the channel to one that no other AP is using (or at least a channel
that has a lower level of interference) in order to give the connected stations a minimum degree of
interference. Dynamic channel selection frees the network administrator from this task by letting
the AP do it automatically. The AP can scan the area around it looking for the channel with the least
amount of interference.
In the 2.4 GHz spectrum, each channel from 1 to 13 is broken up into discrete 22 MHz segments
that are spaced 5 MHz apart. Channel 1 is centered on 2.412 GHz while channel 13 is centered on
2.472 GHz.
NWA5000 / WAC6500 Series User’s Guide
74
Chapter 6 Wireless
Figure 43 An Example Three-Channel Deployment
Three channels are situated in such a way as to create almost no interference with one another if
used exclusively: 1, 6 and 11. When an AP broadcasts on any of these three channels, it should not
interfere with neighboring APs as long as they are also limited to same trio.
Figure 44 An Example Four-Channel Deployment
However, some regions require the use of other channels and often use a safety scheme with the
following four channels: 1, 4, 7 and 11. While they are situated sufficiently close to both each other
and the three so-called “safe” channels (1,6 and 11) that interference becomes inevitable, the
severity of it is dependent upon other factors: proximity to the affected AP, signal strength, activity,
and so on.
Finally, there is an alternative four channel scheme for ETSI, consisting of channels 1, 5, 9, 13. This
offers significantly less overlap that the other one.
Figure 45 An Alternative Four-Channel Deployment
Load Balancing
Because there is a hard upper limit on an AP’s wireless bandwidth, load balancing can be crucial in
areas crowded with wireless users. Rather than let every user connect and subsequently dilute the
available bandwidth to the point where each connecting device receives a meager trickle, the load
balanced AP instead limits the incoming connections as a means to maintain bandwidth integrity.
NWA5000 / WAC6500 Series User’s Guide
75
Chapter 6 Wireless
There are two kinds of wireless load balancing available on the NWA/WAC:
Load balancing by station number limits the number of devices allowed to connect to your AP. If
you know exactly how many stations you want to let connect, choose this option.
For example, if your company’s graphic design team has their own AP and they have 10 computers,
you can load balance for 10. Later, if someone from the sales department visits the graphic design
team’s offices for a meeting and he tries to access the network, his computer’s connection is
delayed, giving it the opportunity to connect to a different, neighboring AP. If he still connects to
the AP regardless of the delay, then the AP may boot other people who are already connected in
order to associate with the new connection.
Load balancing by traffic level limits the number of connections to the AP based on maximum
bandwidth available. If you are uncertain as to the exact number of wireless connections you will
have then choose this option. By setting a maximum bandwidth cap, you allow any number of
devices to connect as long as their total bandwidth usage does not exceed the configured
bandwidth cap associated with this setting. Once the cap is hit, any new connections are rejected or
delayed provided that there are other APs in range.
Imagine a coffee shop in a crowded business district that offers free wireless connectivity to its
customers. The coffee shop owner can’t possibly know how many connections his AP will have at
any given moment. As such, he decides to put a limit on the bandwidth that is available to his
customers but not on the actual number of connections he allows. This means anyone can connect
to his wireless network as long as the AP has the bandwidth to spare. If too many people connect
and the AP hits its bandwidth cap then all new connections must basically wait for their turn or get
shunted to the nearest identical AP.

AP Profile
8.1 Overview
This chapter shows you how to configure preset profiles for the NWA/WAC.
8.1.1 What You Can Do in this Chapter
• The Radio screen (Section 8.2 on page 85) creates radio configurations that can be used by the
APs.
• The SSID screen (Section 8.3 on page 89) configures three different types of profiles for your
networked APs.
8.1.2 What You Need To Know
The following terms and concepts may help as you read this chapter.
Wireless Profiles
At the heart of all wireless AP configurations on the NWA/WAC are profiles. A profile represents a
group of saved settings that you can use across any number of connected APs. You can set up the
following wireless profile types:
• Radio - This profile type defines the properties of an AP’s radio transmitter. You can have a
maximum of 32 radio profiles on the NWA/WAC.
• SSID - This profile type defines the properties of a single wireless network signal broadcast by
an AP. Each radio on a single AP can broadcast up to 8 SSIDs. You can have a maximum of 32
SSID profiles on the NWA/WAC.
• Security - This profile type defines the security settings used by a single SSID. It controls the
encryption method required for a wireless client to associate itself with the SSID. You can have a
maximum of 32 security profiles on the NWA/WAC.
• MAC Filtering - This profile provides an additional layer of security for an SSID, allowing you to
block access or allow access to that SSID based on wireless client MAC addresses. If a client’s
MAC address is on the list, then it is either allowed or denied, depending on how you set up the
MAC Filter profile. You can have a maximum of 32 MAC filtering profiles on the NWA/WAC.
• Layer-2 Isolation - This profile defines the MAC addresses of the devices that you want to allow
the associated wireless clients to have access to when layer-2 isolation is enabled.
SSID
The SSID (Service Set IDentifier) is the name that identifies the Service Set with which a wireless
station is associated. Wireless stations associating to the access point (AP) must have the same
SSID. In other words, it is the name of the wireless network that clients use to connect to it.
NWA5000 / WAC6500 Series User’s Guide
84
Chapter 8 AP Profile
WEP
WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the AP
and the wireless stations associated with it in order to keep network communications private. Both
the wireless stations and the access points must use the same WEP key for data encryption and
decryption.
WPA2
WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption,
authentication and key management than WPA. Key differences between WPA2 and WEP are
improved data encryption and user authentication.
IEEE 802.1x
The IEEE 802.1x standard outlines enhanced security methods for both the authentication of
wireless stations and encryption key management. Authentication is done using an external
RADIUS server.
8.2 Radio
This screen allows you to create radio profiles for the NWA/WAC. A radio profile is a list of settings
that an NWA/WAC can use to configure its radio transmitter(s). To access this screen click
Configuration > Object > AP Profile.
Note: You can have a maximum of 32 radio profiles on the NWA/WAC.

General Settings
Activate
Select this option to make this profile active.
Profile Name
Enter up to 31 alphanumeric characters to be used as this profile’s name. Spaces and
underscores are allowed.
802.11 Band
Select the wireless band which this radio profile should use. Not all NWA/WACs support
both 2.4 GHz and 5 GHz frequency bands.
2.4 GHz is the frequency used by IEEE 802.11b/g/n wireless clients.
5 GHz is the frequency used by IEEE 802.11ac/a/n wireless clients.
If you set 802.11 Band to 2.4G, you can select from the following:
•
•
b/g: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to
associate with the NWA/WAC. The NWA/WAC adjusts the transmission rate
automatically according to the wireless standard supported by the wireless devices.
b/g/n: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN
devices to associate with the NWA/WAC. The transmission rate of your NWA/WAC
might be reduced.
If you set 802.11 Band to 5G, you can select from the following:
•
•
•
Channel Width
a: allows only IEEE 802.11a compliant WLAN devices to associate with the NWA/
WAC.
a/n: allows both IEEE802.11n and IEEE802.11a compliant WLAN devices to
associate with the NWA/WAC. The transmission rate of your NWA/WAC might be
reduced.
ac: allows IEEE 802.11ac compliant WLAN devices to associate with the WAC.
Select the channel bandwidth you want to use for your wireless network.
Select 20 MHz if you want to lessen radio interference with other wireless devices in
your neighborhood.
Select 20/40 MHz to allow the NWA/WAC to choose the channel bandwidth (20 or 40
MHz) that has least interference.
Select 20/40/80 MHz to allow the NWA/WAC to choose the channel bandwidth (20 or
40 or 80 MHz) that has least interference.
Channel
Selection
This is the radio channel which the signal will use for broadcasting by this radio profile.
•
•
DCS: Choose Dynamic Channel Selection to have the NWA/WAC choose a radio
channel that has least interference.
Manual: Choose from the available radio channels in the list. If your NWA/WAC is
outdoor type, be sure to choose non-indoors channels.
DCS Time
Interval
Enter a number of minutes. This regulates how often the NWA/WAC surveys the other
APs within its broadcast radius. If the channel on which it is currently broadcasting
suddenly comes into use by another AP, the NWA/WAC will then dynamically select the
next available clean channel or a channel with lower interference.
Enable DCS
Client Aware
Select this to have the AP wait until all connected clients have disconnected before
switching channels.
If you disable this then the AP switches channels immediately regardless of any client
connections. In this instance, clients that are connected to the AP when it switches
channels are dropped.

2.4 GHz Channel
Selection Method
DESCRIPTION
Select how you want to specify the channels the NWA/WAC switches between for 2.4
GHz operation. This field appears only when you choose 802.11b/g/n mode.
Select auto to have the NWA/WAC display a 2.4 GHz Channel Deployment field you
can use to limit channel switching to 3 or 4 channels.
Select manual to select the individual channels the NWA/WAC switches between.
Select channels from the Available channels list and use the right arrow button to
move them to the Channels selected list.
2.4 GHz Channel
Deployment
This is available when the 2.4 GHz Channel Selection Method is set to auto.
Select Three-Channel Deployment to limit channel switching to channels 1,6, and
11, the three channels that are sufficiently attenuated to have almost no impact on one
another. In other words, this allows you to minimize channel interference by limiting
channel-hopping to these three “safe” channels.
Select Four-Channel Deployment to limit channel switching to four channels.
Depending on the country domain, if the only allowable channels are 1-11 then the
NWA/WAC uses channels 1, 4, 7, 11 in this configuration; otherwise, the NWA/WAC
uses channels 1, 5, 9, 13 in this configuration. Four channel deployment expands your
pool of possible channels while keeping the channel interference to a minimum.
Enable 5 GHz
DFS Aware
Select this if your APs are operating in an area known to have RADAR devices. This
allows the devide to downgrade its frequency to below 5 GHz in the event RADAR signal
is detected, thus preventing it from interfering with that signal.
Enabling this forces the AP to select a non-DFS channel.
5 GHz Channel
Selection Method
Select how you want to specify the channels the NWA/WAC switches between for 5 GHz
operation.
Select Auto to have the NWA/WAC automatically select the best channel.
Advanced Settings
Guard Interval
Set the guard interval for this radio profile to either short or long. This option isn’t
applicable if you choose 20 MHz channel width.
The guard interval is the gap introduced between data transmission from users in order
to reduce interference. Reducing the interval increases data transfer rates but also
increases interference. Increasing the interval reduces data transfer rates but also
reduces interference.
Enable A-MPDU
Aggregation
Select this to enable A-MPDU aggregation.
Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames along with
their 802.11n headers and wraps them in a 802.11n MAC header. This method is useful
for increasing bandwidth throughput in environments that are prone to high error
rates.
Enable A-MSDU
Aggregation
Select this to enable A-MSDU aggregation.
RTS/CTS
Threshold
Use RTS/CTS to reduce data collisions on the wireless network if you have wireless
clients that are associated with the same AP but out of range of one another. When
enabled, a wireless client sends an RTS (Request To Send) and then waits for a CTS
(Clear To Send) before it transmits. This stops wireless clients from transmitting
packets at the same time (and causing data collisions).
Mac Service Data Unit (MSDU) aggregation collects Ethernet frames without any of
their 802.11n headers and wraps the header-less payload in a single 802.11n MAC
header. This method is useful for increasing bandwidth throughput. It is also more
efficient than A-MPDU except in environments that are prone to high error rates.
A wireless client sends an RTS for all packets larger than the number (of bytes) that
you enter here. Set the RTS/CTS equal to or higher than the fragmentation threshold to
turn RTS/CTS off.

LABEL
DESCRIPTION
Beacon Interval
When a wirelessly networked device sends a beacon, it includes with it a beacon
interval. This specifies the time period before the device sends the beacon again. The
interval tells receiving devices on the network how long they can wait in low-power
mode before waking up to handle the beacon. A high value helps save current
consumption of the access point.
DTIM
Delivery Traffic Indication Message (DTIM) is the time period after which broadcast and
multicast packets are transmitted to mobile clients in the Active Power Management
mode. A high DTIM value can cause clients to lose connectivity with the network. This
value can be set from 1 to 255.
Enable Signal
Threshold
Select the check box to use the signal threshold to ensure wireless clients receive good
throughput. This allows only wireless clients with a strong signal to connect to the AP.
Clear the check box to not require wireless clients to have a minimum signal strength
to connect to the AP.
Station Signal
Threshold
Set a minimum client signal strength. A wireless client is allowed to connect to the AP
only when its signal strength is stronger than the specified threshold.
-20 dBm is the strongest signal you can require and -76 is the weakest.
Disassociate
Station
Threshold
Set a minimum kick-off signal strength. When a wireless client’s signal strength is
lower than the specified threshold, the NWA/WAC disconnects the wireless client from
the AP.
-20 dBm is the strongest signal you can require and -90 is the weakest.
Allow Station
Connection after
Multiple Retries
Select this option to allow a wireless client to try to associate with the AP again after it
is disconnected due to weak signal strength.
Station Retry
Count
Set the maximum number of times a wireless client can attempt to re-connect to the
AP
Multicast Settings
Transmission
Mode
Specify how the NWA/WAC handles wireless multicast traffic.
Select Multicast to Unicast to broadcast wireless multicast traffic to all of the wireless
clients as unicast traffic. Unicast traffic dynamically changes the data rate based on the
application’s bandwidth requirements. The retransmit mechanism of unicast traffic
provides more reliable transmission of the multicast traffic, although it also produces
duplicate packets.
Select Fixed Multicast Rate to send multicast traffic to all wireless clients at a single
data rate. You must know the multicast application’s bandwidth requirements and set it
in the following field.
Multicast
Rate(Mbps)
If you set Transmission Mode to Fixed Multicast Rate, select a data rate at which
the NWA/WAC transmits multicast packets to wireless clients. For example, to deploy 4
Mbps video, select a fixed multicast rate higher than 4 Mbps.

8.3 SSID
The SSID screens allow you to configure three different types of profiles for your networked APs: an
SSID list, which can assign specific SSID configurations to your APs; a security list, which can
assign specific encryption methods to the APs when allowing wireless clients to connect to them;
and a MAC filter list, which can limit connections to an AP based on wireless clients MAC addresses.

DESCRIPTION
QoS
Select a Quality of Service (QoS) access category to associate with this SSID. Access
categories minimize the delay of data packets across a wireless network. Certain
categories, such as video or voice, are given a higher priority due to the time sensitive
nature of their data packets.
QoS access categories are as follows:
disable: Turns off QoS for this SSID. All data packets are treated equally and not tagged
with access categories.
WMM: Enables automatic tagging of data packets. The NWA/WAC assigns access
categories to the SSID by examining data as it passes through it and making a best guess
effort. If something looks like video traffic, for instance, it is tagged as such.
WMM_VOICE: All wireless traffic to the SSID is tagged as voice data. This is
recommended if an SSID is used for activities like placing and receiving VoIP phone calls.
WMM_VIDEO: All wireless traffic to the SSID is tagged as video data. This is
recommended for activities like video conferencing.
WMM_BEST_EFFORT: All wireless traffic to the SSID is tagged as “best effort,” meaning
the data travels the best route it can without displacing higher priority traffic. This is good
for activities that do not require the best bandwidth throughput, such as surfing the
Internet.
WMM_BACKGROUND: All wireless traffic to the SSID is tagged as low priority or
“background traffic”, meaning all other access categories take precedence over this one. If
traffic from an SSID does not have strict throughput requirements, then this access
category is recommended. For example, an SSID that only has network printers connected
to it.
VLAN ID
Enter a VLAN ID for the NWA/WAC to use to tag traffic originating from this SSID.
Hidden SSID
Select this if you want to “hide” your SSID from wireless clients. This tells any wireless
clients in the vicinity of the AP using this SSID profile not to display its SSID name as a
potential connection. Not all wireless clients respect this flag and display it anyway.
When a SSID is “hidden” and a wireless client cannot see it, the only way you can connect
to the SSID is by manually entering the SSID name in your wireless connection setup
screen(s) (these vary by client, client connectivity software, and operating system).

9.3 Technical Reference
The following section contains additional technical information about the features described in this
chapter.
Rogue APs
Rogue APs are wireless access points operating in a network’s coverage area that are not under the
control of the network’s administrators, and can open up holes in a network’s security. Attackers
can take advantage of a rogue AP’s weaker (or non-existent) security to gain access to the network,
or set up their own rogue APs in order to capture information from wireless clients. If a scan reveals
a rogue AP, you can use commercially-available software to physically locate it.
NWA5000 / WAC6500 Series User’s Guide

Chapter 9 MON Profile
Figure 63 Rogue AP Example
RG
In the example above, a corporate network’s security is compromised by a rogue AP (RG) set up by
an employee at his workstation in order to allow him to connect his notebook computer wirelessly
(A). The company’s legitimate wireless network (the dashed ellipse B) is well-secured, but the
rogue AP uses inferior security that is easily broken by an attacker (X) running readily available
encryption-cracking software. In this example, the attacker now has access to the company
network, including sensitive data stored on the file server (C).
Friendly APs
If you have more than one AP in your wireless network, you should also configure a list of “friendly”
APs. Friendly APs are other wireless access points that are detected in your network, as well as any
others that you know are not a threat (those from recognized networks, for example). It is
recommended that you export (save) your list of friendly APs often, especially if you have a
network with a large number of access points.

Certificates
11.1 Overview
The NWA/WAC can use certificates (also called digital IDs) to authenticate users. Certificates are
based on public-private key pairs. A certificate contains the certificate owner’s identity and public
key. Certificates provide a way to exchange public keys for use in authentication.
11.1.1 What You Can Do in this Chapter
• The My Certificate screens (Section 11.2 on page 111) generate and export self-signed
certificates or certification requests and import the NWA/WAC’s CA-signed certificates.
• The Trusted Certificates screens (Section 11.3 on page 119) save CA certificates and trusted
remote host certificates to the NWA/WAC. The NWA/WAC trusts any valid certificate that you
have imported as a trusted certificate. It also trusts any valid certificate signed by any of the
certificates that you have imported as a trusted certificate.
11.1.2 What You Need to Know
The following terms and concepts may help as you read this chapter.
When using public-key cryptology for authentication, each host has two keys. One key is public and
can be made openly available. The other key is private and must be kept secure.
These keys work like a handwritten signature (in fact, certificates are often referred to as “digital
signatures”). Only you can write your signature exactly as it should look. When people know what
your signature looks like, they can verify whether something was signed by you, or by someone
else. In the same way, your private key “writes” your digital signature and your public key allows
people to verify whether data was signed by you, or by someone else.
This process works as follows:
Tim wants to send a message to Jenny. He needs her to be sure that it comes from him, and that
the message content has not been altered by anyone else along the way. Tim generates a public
key pair (one public key and one private key).
Tim keeps the private key and makes the public key openly available. This means that anyone who
receives a message seeming to come from Tim can read it and verify whether it is really from him
or not.
Tim uses his private key to sign the message and sends it to Jenny.
Jenny receives the message and uses Tim’s public key to verify it. Jenny knows that the message is
from Tim, and that although other people may have been able to read the message, no-one can
have altered it (because they cannot re-sign the message with Tim’s private key).
NWA5000 / WAC6500 Series User’s Guide
108
Chapter 11 Certificates
Additionally, Jenny uses her own private key to sign a message and Tim uses Jenny’s public key to
verify the message.
The NWA/WAC uses certificates based on public-key cryptology to authenticate users attempting to
establish a connection, not to encrypt the data that you send after establishing a connection. The
method used to secure the data that you send through an established connection depends on the
type of connection.
The certification authority uses its private key to sign certificates. Anyone can then use the
certification authority’s public key to verify the certificates.
A certification path is the hierarchy of certification authority certificates that validate a certificate.
The NWA/WAC does not trust a certificate if any certificate on its path has expired or been revoked.
Certification authorities maintain directory servers with databases of valid and revoked certificates.
A directory of certificates that have been revoked before the scheduled expiration is called a CRL
(Certificate Revocation List). The NWA/WAC can check a peer’s certificate against a directory
server’s list of revoked certificates. The framework of servers, software, procedures and policies
that handles keys is called PKI (public-key infrastructure).
Advantages of Certificates
Certificates offer the following benefits.
• The NWA/WAC only has to store the certificates of the certification authorities that you decide to
trust, no matter how many devices you need to authenticate.
• Key distribution is simple and very secure since you can freely distribute public keys and you
never need to transmit private keys.
Self-signed Certificates
You can have the NWA/WAC act as a certification authority and sign its own certificates.
Factory Default Certificate
The NWA/WAC generates its own unique self-signed certificate when you first turn it on. This
certificate is referred to in the GUI as the factory default certificate.
Certificate File Formats
Any certificate that you want to import has to be in one of these file formats:
• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.
• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters,
uppercase letters and numerals to convert a binary X.509 certificate into a printable form.
• Binary PKCS#7: This is a standard that defines the general syntax for data (including digital
signatures) that may be encrypted. A PKCS #7 file is used to transfer a public key certificate. The
private key is not included. The NWA/WAC currently allows the importation of a PKS#7 file that
contains a single certificate.
• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses lowercase
letters, uppercase letters and numerals to convert a binary PKCS#7 certificate into a printable
form.
NWA5000 / WAC6500 Series User’s Guide
109
Chapter 11 Certificates
• Binary PKCS#12: This is a format for transferring public key and private key certificates.The
private key in a PKCS #12 file is within a password-encrypted envelope. The file’s password is not
connected to your certificate’s public or private passwords. Exporting a PKCS #12 file creates this
and you must provide it to decrypt the contents when you import the file into the NWA/WAC.
Note: Be careful not to convert a binary file to text during the transfer process. It is easy
for this to occur since many programs use text files by default.
11.1.3 Verifying a Certificate
Before you import a trusted certificate into the NWA/WAC, you should verify that you have the
correct certificate. You can do this using the certificate’s fingerprint. A certificate’s fingerprint is a
message digest calculated using the MD5 or SHA1 algorithm. The following procedure describes
how to check a certificate’s fingerprint to verify that you have the actual certificate.
Browse to where you have the certificate saved on your computer.
Make sure that the certificate has a “.cer” or “.crt” file name extension.
Double-click the certificate’s icon to open the Certificate window. Click the Details tab and scroll
down to the Thumbprint Algorithm and Thumbprint fields.
Use a secure method to verify that the certificate owner has the same information in the
Thumbprint Algorithm and Thumbprint fields. The secure method may very based on your
situation. Possible examples would be over the telephone or through an HTTPS connection.

11.4 Technical Reference
The following section contains additional technical information about the features described in this
chapter.
OCSP
OCSP (Online Certificate Status Protocol) allows an application or device to check whether a
certificate is valid. With OCSP the NWA/WAC checks the status of individual certificates instead of
downloading a Certificate Revocation List (CRL). OCSP has two main advantages over a CRL. The
first is real-time status information. The second is a reduction in network traffic since the NWA/WAC
only gets information on the certificates that it needs to verify, not a huge list. When the NWA/WAC
requests certificate status information, the OCSP server returns a “expired”, “current” or “unknown”
response.

12.3.1 Pre-defined NTP Time Servers List
When you turn on the NWA/WAC for the first time, the date and time start at 2003-01-01
00:00:00. The NWA/WAC then attempts to synchronize with one of the following pre-defined list of
Network Time Protocol (NTP) time servers.
The NWA/WAC continues to use the following pre-defined list of NTP time servers if you do not
specify a time server or it cannot synchronize with the time server you specified.
Table 65 Default Time Servers
0.pool.ntp.org
1.pool.ntp.org
2.pool.ntp.org
When the NWA/WAC uses the pre-defined list of NTP time servers, it randomly selects one server
and tries to synchronize with it. If the synchronization fails, then the NWA/WAC goes through the
rest of the list in order from the first one tried until either it is successful or all the pre-defined NTP
time servers have been tried.

12.4 WWW Overview
The following figure shows secure and insecure management of the NWA/WAC coming in from the
WAN. HTTPS and SSH access are secure. HTTP, Telnet, and FTP management access are not secure.
NWA5000 / WAC6500 Series User’s Guide
129
Chapter 12 System
Figure 76 Secure and Insecure Service Access From the WAN
12.4.1 Service Access Limitations
A service cannot be used to access the NWA/WAC when you have disabled that service in the
corresponding screen.
12.4.2 System Timeout
There is a lease timeout for administrators. The NWA/WAC automatically logs you out if the
management session remains idle for longer than this timeout period. The management session
does not time out when a statistics screen is polling.
Each user is also forced to log in the NWA/WAC for authentication again when the reauthentication
time expires.
You can change the timeout settings in the User screens.
12.4.3 HTTPS
You can set the NWA/WAC to use HTTP or HTTPS (HTTPS adds security) for Web Configurator
sessions.
HTTPS (HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a web protocol
that encrypts and decrypts web pages. Secure Socket Layer (SSL) is an application-level protocol
that enables secure transactions of data by ensuring confidentiality (an unauthorized party cannot
read the transferred data), authentication (one party can identify the other party) and data
integrity (you know if data has been changed).
It relies upon certificates, public keys, and private keys (see Chapter 11 on page 108 for more
information).
HTTPS on the NWA/WAC is used so that you can securely access the NWA/WAC using the Web
Configurator. The SSL protocol specifies that the HTTPS server (the NWA/WAC) must always
authenticate itself to the HTTPS client (the computer which requests the HTTPS connection with the
NWA/WAC), whereas the HTTPS client only should authenticate itself when the HTTPS server
requires it to do so (select Authenticate Client Certificates in the WWW screen). Authenticate
Client Certificates is optional and if selected means the HTTPS client must send the NWA/WAC a

certificate. You must apply for a certificate for the browser from a CA that is a trusted CA on the
NWA/WAC.
Please refer to the following figure.
HTTPS connection requests from an SSL-aware web browser go to port 443 (by default) on the
NWA/WAC’s web server.
HTTP connection requests from a web browser go to port 80 (by default) on the NWA/WAC’s web
server.
Figure 77 HTTP/HTTPS Implementation
Note: If you disable HTTP in the WWW screen, then the NWA/WAC blocks all HTTP
connection attempts.

12.4.5.3 Avoiding Browser Warning Messages
Here are the main reasons your browser displays warnings about the NWA/WAC’s HTTPS server
certificate and what you can do to avoid seeing the warnings:
• The issuing certificate authority of the NWA/WAC’s HTTPS server certificate is not one of the
browser’s trusted certificate authorities. The issuing certificate authority of the NWA/WAC's
factory default certificate is the NWA/WAC itself since the certificate is a self-signed certificate.
NWA5000 / WAC6500 Series User’s Guide
134
Chapter 12 System
• For the browser to trust a self-signed certificate, import the self-signed certificate into your
operating system as a trusted certificate.
• To have the browser trust the certificates issued by a certificate authority, import the certificate
authority’s certificate into your operating system as a trusted certificate. Refer to Appendix A on
page 188 for details.
12.4.5.4 Enrolling and Importing SSL Client Certificates
The SSL client needs a certificate if Authenticate Client Certificates is selected on the NWA/
WAC.
You must have imported at least one trusted CA to the NWA/WAC in order for the Authenticate
Client Certificates to be active (see the Certificates chapter for details).
Apply for a certificate from a Certification Authority (CA) that is trusted by the NWA/WAC (see the
NWA/WAC’s Trusted Certificates Web Configurator screen).

12.5 SSH
You can use SSH (Secure SHell) to securely access the NWA/WAC’s command line interface.
SSH is a secure communication protocol that combines authentication and data encryption to
provide secure encrypted communication between two hosts over an unsecured network. In the
following figure, computer B on the Internet uses SSH to securely connect to the NWA/WAC (A) for
a management session.
Figure 83 SSH Communication Over the WAN Example
12.5.1 How SSH Works
The following figure is an example of how a secure connection is established between two remote
hosts using SSH v1.
NWA5000 / WAC6500 Series User’s Guide
140
Chapter 12 System
Figure 84 How SSH v1 Works Example
Host Identification
The SSH client sends a connection request to the SSH server. The server identifies itself with a
host key. The client encrypts a randomly generated session key with the host key and server key
and sends the result back to the server.
The client automatically saves any new server public keys. In subsequent connections, the server
public key is checked against the saved version on the client computer.
Encryption Method
Once the identification is verified, both the client and server must agree on the type of encryption
method to use.
Authentication and Data Transmission
After the identification is verified and data encryption activated, a secure tunnel is established
between the client and the server. The client then sends its authentication information (user
name and password) to the server to log in to the server.
12.5.2 SSH Implementation on the NWA/WAC
Your NWA/WAC supports SSH versions 1 and 2 using RSA authentication and four encryption
methods (AES, 3DES, Archfour, and Blowfish). The SSH server is implemented on the NWA/WAC for
management using port 22 (by default).

12.8 SNMP
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your NWA/WAC supports SNMP agent functionality, which allows a
manager station to manage and monitor the NWA/WAC through the network. The NWA/WAC
supports SNMP version one (SNMPv1), version two (SNMPv2c), and version three (SNMPv3). The
next figure illustrates an SNMP management operation.
NWA5000 / WAC6500 Series User’s Guide
145
Chapter 12 System
Figure 91 SNMP Management Model
An SNMP managed network consists of two main types of component: agents and a manager.
An agent is a management software module that resides in a managed device (the NWA/WAC). An
agent translates the local management information from the managed device into a form
compatible with SNMP. The manager is the console through which network administrators perform
network management functions. It executes applications that control and monitor managed
devices.
The managed devices contain object variables/managed objects that define each piece of
information to be collected about a device. Examples of variables include such as number of
packets received, node port status etc. A Management Information Base (MIB) is a collection of
managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing
these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The
manager issues a request and the agent returns responses using the following protocol operations:
• Get - Allows the manager to retrieve an object variable from the agent.
• GetNext - Allows the manager to retrieve the next object variable from a table or list within an
agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it
initiates a Get operation, followed by a series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.
12.8.1 Supported MIBs
The NWA/WAC supports MIB II that is defined in RFC-1213 and RFC-1215. The NWA/WAC also
supports private MIBs (ZYXEL-ES-CAPWAP.MIB, ZYXEL-ES-COMMON.MIB, ZYXEL-ESZyXELAPMgmt.MIB, ZYXEL-ES-PROWLAN.MIB, ZYXEL-ES-RFMGMT.MIB, ZYXEL-ES-SMI.MIB, and
NWA5000 / WAC6500 Series User’s Guide
146
Chapter 12 System
ZYXEL-ES-WIRELESS.MIB) to collect information about CPU and memory usage and VPN total
throughput. The focus of the MIBs is to let administrators collect statistical data and monitor status
and performance. You can download the NWA/WAC’s MIBs from www.zyxel.com.
12.8.2 SNMP Traps
The NWA/WAC will send traps to the SNMP manager when any one of the following events occurs.
Table 70 SNMP Traps

13.3 Log Setting
These screens control log messages and alerts. A log message stores the information for viewing
(for example, in the Monitor > View Log screen) or regular e-mailing later, and an alert is emailed immediately. Usually, alerts are used for events that require more serious attention, such as
system errors and attacks.
The NWA/WAC provides a system log and supports e-mail profiles and remote syslog servers. The
system log is available on the View Log screen, the e-mail profiles are used to mail log messages
to the specified destinations, and the other four logs are stored on specified syslog servers.
The Log Setting tab also controls what information is saved in each log. For the system log, you
can also specify which log messages are e-mailed, where they are e-mailed, and how often they are
e-mailed.
For alerts, the Log Setting screen controls which events generate alerts and where alerts are emailed.
The Log Setting screen provides a summary of all the settings. You can use the Edit Log Setting
screen to maintain the detailed settings (such as log categories, e-mail addresses, server names,
etc.) for any log. Alternatively, if you want to edit what events is included in each log, you can also
use the Active Log Summary screen to edit this information for all logs at the same time.

14.1 Overview
Configuration files define the NWA/WAC’s settings. Shell scripts are files of commands that you can
store on the NWA/WAC and run when you need them. You can apply a configuration file or run a
shell script without the NWA/WAC restarting. You can store multiple configuration files and shell
script files on the NWA/WAC. You can edit configuration files or shell scripts in a text editor and
upload them to the NWA/WAC. Configuration files use a .conf extension and shell scripts use a .zysh
extension.
14.1.1 What You Can Do in this Chapter
• The Configuration File screen (Section 14.2 on page 163) stores and names configuration files.
You can also download and upload configuration files.
• The Firmware Package screen (Section 14.3 on page 168) checks your current firmware
version and uploads firmware to the NWA/WAC.
• The Shell Script screen (Section 14.4 on page 170) stores, names, downloads, uploads and runs
shell script files.
14.1.2 What you Need to Know
The following terms and concepts may help as you read this chapter.
Configuration Files and Shell Scripts
When you apply a configuration file, the NWA/WAC uses the factory default settings for any
features that the configuration file does not include. When you run a shell script, the NWA/WAC
only applies the commands that it contains. Other settings do not change.
These files have the same syntax, which is also identical to the way you run CLI commands
manually. An example is shown below
# enter configuration mode
configure terminal
# change administrator password
username admin password 4321 user-type admin
#configure default radio profile, change 2GHz channel to 11 & Tx output power # to
50%
wlan-radio-profile default
2g-channel 11
output-power 50%
exit
write
NWA5000 / WAC6500 Series User’s Guide
162
Chapter 14 File Manager
While configuration files and shell scripts have the same syntax, the NWA/WAC applies
configuration files differently than it runs shell scripts. This is explained below.

Shell Scripts (.zysh)

Runs the commands in the shell script.
You have to run the aforementioned example as a shell script because the first command is run in
Privilege mode. If you remove the first command, you have to run the example as a configuration
file because the rest of the commands are executed in Configuration mode.
Comments in Configuration Files or Shell Scripts
In a configuration file or shell script, use “#” or “!” as the first character of a command line to have
the NWA/WAC treat the line as a comment.
Your configuration files or shell scripts can use “exit” or a command line consisting of a single “!” to
have the NWA/WAC exit sub command mode.
Note: “exit” or “!'” must follow sub commands if it is to make the NWA/WAC exit sub
command mode.
In the following example lines 1 and 2 are comments. Line 5 exits sub command mode.
! this is from Joe
# on 2010/12/05
wlan-ssid-profile default
ssid Joe-AP
qos wmm
security default
Errors in Configuration Files or Shell Scripts
When you apply a configuration file or run a shell script, the NWA/WAC processes the file line-byline. The NWA/WAC checks the first line and applies the line if no errors are detected. Then it
continues with the next line. If the NWA/WAC finds an error, it stops applying the configuration file
or shell script and generates a log.
You can change the way a configuration file or shell script is applied. Include setenv stop-onerror off in the configuration file or shell script. The NWA/WAC ignores any errors in the
configuration file or shell script and applies all of the valid commands. The NWA/WAC still generates
a log for any errors.
14.2 Configuration File
Click Maintenance > File Manager > Configuration File to open this screen. Use the
Configuration File screen to store, run, and name configuration files. You can also download
NWA5000 / WAC6500 Series User’s Guide

Chapter 14 File Manager
configuration files from the NWA/WAC to your computer and upload configuration files from your
computer to the NWA/WAC.
Once your NWA/WAC is configured and functioning properly, it is highly recommended that you
back up your configuration file before making further configuration changes. The backup
configuration file will be useful in case you need to return to your previous settings.
Configuration File Flow at Restart
• If there is not a startup-config.conf when you restart the NWA/WAC (whether through a
management interface or by physically turning the power off and back on), the NWA/WAC uses
the system-default.conf configuration file with the NWA/WAC’s default settings.
• If there is a startup-config.conf, the NWA/WAC checks it for errors and applies it. If there are
no errors, the NWA/WAC uses it and copies it to the lastgood.conf configuration file as a back
up file. If there is an error, the NWA/WAC generates a log and copies the startup-config.conf
configuration file to the startup-config-bad.conf configuration file and tries the existing
lastgood.conf configuration file. If there isn’t a lastgood.conf configuration file or it also has
an error, the NWA/WAC applies the system-default.conf configuration file.
• You can change the way the startup-config.conf file is applied. Include the setenv-startup
stop-on-error off command. The NWA/WAC ignores any errors in the startup-config.conf
file and applies all of the valid commands. The NWA/WAC still generates a log for any errors.

The LED Suppression feature allows you to control how the LEDs of your NWA/WAC behave after
it’s ready. The deafult LED suppression setting of your AP is different depending on your NWA/WAC
model.
You can go to Maintenance > LEDs > Suppression screen to see the default of the LED behavior.
If the Suppression On check box is checked, it means the LEDs of your NWA/WAC will turn off
after it’s ready. On the other hand, if the check box is unchecked, it means the LEDs will stay lit
after the AP is ready.
You can change the LED suppression setting in the Maintenance > LEDs > Suppression screen.
After you make changes in the suppression screen, it will be stored as the default when the NWA/
WAC is restarted. See (Section 1.6 on page 20) for information on default values for different
models.
Note: When the NWA/WAC is booting or performing firmware upgrade, the LEDs will lit
regardless of the setting in LED suppression.

19.5 Wireless Connections
I cannot access the NWA/WAC or ping any computer from the WLAN.
Make sure the wireless LAN (wireless radio) is enabled on the NWA/WAC.
Make sure the radio or at least one of the NWA/WAC’s radios is operating in AP mode.
Make sure the wireless adapter (installed on your computer) is working properly.
Make sure the wireless adapter (installed on your computer) is IEEE 802.11 compatible and
supports the same wireless standard as the NWA/WAC’s active radio.
Make sure your computer (with a wireless adapter installed) is within the transmission range of the
NWA/WAC.
Check that both the NWA/WAC and your computer are using the same wireless and wireless
security settings.
Hackers have accessed my WEP-encrypted wireless LAN.
WEP is extremely insecure. Its encryption can be broken by an attacker, using widely-available
software. It is strongly recommended that you use a more effective security mechanism. Use the
strongest security mechanism that all the wireless devices in your network support. WPA2 or WPA2PSK is recommended.
The wireless security is not following the re-authentication timer setting I specified.
If a RADIUS server authenticates wireless stations, the re-authentication timer on the RADIUS
server has priority. Change the RADIUS server’s configuration if you need to use a different reauthentication timer setting.
I cannot get a certificate to import into the NWA/WAC.
For My Certificates, you can import a certificate that matches a corresponding certification
request that was generated by the NWA/WAC. You can also import a certificate in PKCS#12 format,
including the certificate’s public and private keys.
You must remove any spaces from the certificate’s filename before you can import the certificate.
Any certificate that you want to import has to be in one of these file formats:
NWA5000 / WAC6500 Series User’s Guide
184
Chapter 19 Troubleshooting
• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.
• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters,
uppercase letters and numerals to convert a binary X.509 certificate into a printable form.
• Binary PKCS#7: This is a standard that defines the general syntax for data (including digital
signatures) that may be encrypted. A PKCS #7 file is used to transfer a public key certificate. The
private key is not included. The NWA/WAC currently allows the importation of a PKS#7 file that
contains a single certificate.
• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses lowercase
letters, uppercase letters and numerals to convert a binary PKCS#7 certificate into a printable
form.
• Binary PKCS#12: This is a format for transferring public key and private key certificates.The
private key in a PKCS #12 file is within a password-encrypted envelope. The file’s password is not
connected to your certificate’s public or private passwords. Exporting a PKCS #12 file creates this
and you must provide it to decrypt the contents when you import the file into the NWA/WAC.
Note: Be careful not to convert a binary file to text during the transfer process. It is easy
for this to occur since many programs use text files by default.
I can only see newer logs. Older logs are missing.
When a log reaches the maximum number of log messages, new log messages automatically
overwrite existing log messages, starting with the oldest existing log message first.
The commands in my configuration file or shell script are not working properly.
• In a configuration file or shell script, use “#” or “!” as the first character of a command line to
have the NWA/WAC treat the line as a comment.
• Your configuration files or shell scripts can use “exit” or a command line consisting of a single “!”
to have the NWA/WAC exit sub command mode.
• Include write commands in your scripts. Otherwise the changes will be lost when the NWA/WAC
restarts. You could use multiple write commands in a long script.
Note: “exit” or “!'” must follow sub commands if it is to make the NWA/WAC exit sub

• Make sure that all the APs used by the wireless clients in question share the same SSID, security,
and radio settings.
• Make sure that all the APs are in the same broadcast domain.
• Make sure that the wireless clients are in range of the other APs; if they are only in range of a
single AP, then load balancing may not be as effective.
In the Monitor > Wireless > AP Information > Radio List screen, there is no load
balancing indicator associated with any APs assigned to the load balancing task.
• Check to be sure that the AP profile which contains the load balancing settings is correctly
assigned to the APs in question.
• The load balancing task may have been terminated because further load balancing on the APs in
question is no longer required.
How do I remove the WAC from its mounting bracket?
• Find the down arrow close to the Ethernet ports, then use a thin flat tool (for example, a flat

19.6 Resetting the NWA/WAC
If you cannot access the NWA/WAC by any method, try restarting it by turning the power off and
then on again. If you still cannot access the NWA/WAC by any method or you forget the
administrator password(s), you can reset the NWA/WAC to its factory-default settings. Any
configuration files or shell scripts that you saved on the NWA/WAC should still be available
afterwards.
Use the following procedure to reset the NWA/WAC to its factory-default settings. This overwrites
the settings in the startup-config.conf file with the settings in the system-default.conf file.
Note: This procedure removes the current configuration.
Make sure the Power LED is on and not blinking.
Press the RESET button and hold it until the Power LED begins to blink. (This usually takes about
ten seconds.)
Release the RESET button, and wait for the NWA/WAC to restart.
You should be able to access the NWA/WAC using the default settings.

Importing Certificates
This appendix shows you how to import public key certificates into your web browser.
Public key certificates are used by web browsers to ensure that a secure web site is legitimate.
When a certificate authority such as VeriSign, Comodo, or Network Solutions, to name a few,
receives a certificate request from a website operator, they confirm that the web domain and
contact information in the request match those on public record with a domain name registrar. If
they match, then the certificate is issued to the website operator, who then places it on the site to
be issued to all visiting web browsers to let them know that the site is legitimate.
Many ZyXEL products, such as the NWA/WAC, issue their own public key certificates. These can be
used by web browsers on a LAN or WAN to verify that they are in fact connecting to the legitimate
device and not one masquerading as it. However, because the certificates were not issued by one of
the several organizations officially recognized by the most common web browsers, you will need to
import the ZyXEL-created certificate into your web browser and flag that certificate as a trusted
authority.
Note: You can see if you are browsing on a secure website if the URL in your web

IPv6
Overview
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The
increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 1038 IP
addresses.
IPv6 Addressing
The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This
is an example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So 2001:0db8:1a2b:0015:0000:0000:1a2f:0000 can
be written as 2001:db8:1a2b:15:0:0:1a2f:0.
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double colon can
only appear once in an IPv6 address. So 2001:0db8:0000:0000:1a2f:0000:0000:0015 can be
written as 2001:0db8::1a2f:0000:0000:0015, 2001:0db8:0000:0000:1a2f::0015,
2001:db8::1a2f:0:0:15 or 2001:db8:0:0:1a2f::15.
Prefix and Prefix Length
Similar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An
IPv6 prefix length specifies how many most significant bits (start from the left) in the address
compose the network address. The prefix length is written as “/x” where x is a number. For
example,
2001:db8:1a2b:15::1a2f:0/32
means that the first 32 bits (2001:db8) is the subnet prefix.
Link-local Address
A link-local address uniquely identifies a device on the local network (the LAN). It is similar to a
“private IP address” in IPv4. You can have the same link-local address on multiple interfaces on a
device. A link-local unicast address has a predefined prefix of fe80::/10. The link-local unicast
address format is as follows.

10 bits
54 bits
64 bits
NWA5000 / WAC6500 Series User’s Guide
201
Appendix B IPv6
Global Address
A global address uniquely identifies a device on the Internet. It is similar to a “public IP address” in
IPv4. A global unicast address starts with a 2 or 3.
Unspecified Address
An unspecified address (0:0:0:0:0:0:0:0 or ::) is used as the source address when a device does
not have its own address. It is similar to “0.0.0.0” in IPv4.
Loopback Address
A loopback address (0:0:0:0:0:0:0:1 or ::1) allows a host to send packets to itself. It is similar to
“127.0.0.1” in IPv4.
Multicast Address
In IPv6, multicast addresses provide the same functionality as IPv4 broadcast addresses.
Broadcasting is not supported in IPv6. A multicast address allows a host to send packets to all hosts
in a multicast group.
Multicast scope allows you to determine the size of the multicast group. A multicast address has a
predefined prefix of ff00::/8. The following table describes some of the predefined multicast
addresses.

Subnet Masking
Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided
into eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each
character (1 ~ 10, A ~ F). Each block’s 16 bits are then represented by four hexadecimal
characters. For example, FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000.
Interface ID
In IPv6, an interface ID is a 64-bit identifier. It identifies a physical interface (for example, an
Ethernet port) or a virtual interface (for example, the management IP address for a VLAN). One
interface should have a unique interface ID.
EUI-64
The EUI-64 (Extended Unique Identifier) defined by the IEEE (Institute of Electrical and Electronics
Engineers) is an interface ID format designed to adapt with IPv6. It is derived from the 48-bit (6byte) Ethernet MAC address as shown next. EUI-64 inserts the hex digits fffe between the third and
fourth bytes of the MAC address and complements the seventh bit of the first byte of the MAC
address. See the following example.

Stateless Autoconfiguration
With stateless autoconfiguration in IPv6, addresses can be uniquely and automatically generated.
Unlike DHCPv6 (Dynamic Host Configuration Protocol version six) which is used in IPv6 stateful
autoconfiguration, the owner and status of addresses don’t need to be maintained by a DHCP
server. Every IPv6 device is able to generate its own and unique IP address automatically when
IPv6 is initiated on its interface. It combines the prefix and the interface ID (generated from its own
Ethernet MAC address, see Interface ID and EUI-64) to form a complete IPv6 address.
When IPv6 is enabled on a device, its interface automatically generates a link-local address
(beginning with fe80).
When the interface is connected to a network with a router and the NWA/WAC is set to
automatically obtain an IPv6 network prefix from the router for the interface, it generates 1another
NWA5000 / WAC6500 Series User’s Guide
203
Appendix B IPv6
address which combines its interface ID and global and subnet information advertised from the
router. This is a routable global IP address.
DHCPv6
The Dynamic Host Configuration Protocol for IPv6 (DHCPv6, RFC 3315) is a server-client protocol
that allows a DHCP server to assign and pass IPv6 network addresses, prefixes and other
configuration information to DHCP clients. DHCPv6 servers and clients exchange DHCP messages
using UDP.
Each DHCP client and server has a unique DHCP Unique IDentifier (DUID), which is used for
identification when they are exchanging DHCPv6 messages. The DUID is generated from the MAC
address, time, vendor assigned ID and/or the vendor's private enterprise number registered with
the IANA. It should not change over time even after you reboot the device.
Identity Association
An Identity Association (IA) is a collection of addresses assigned to a DHCP client, through which
the server and client can manage a set of related IP addresses. Each IA must be associated with
exactly one interface. The DHCP client uses the IA assigned to an interface to obtain configuration
from a DHCP server for that interface. Each IA consists of a unique IAID and associated IP
information.
The IA type is the type of address in the IA. Each IA holds one type of address. IA_NA means an
identity association for non-temporary addresses and IA_TA is an identity association for temporary
addresses. An IA_NA option contains the T1 and T2 fields, but an IA_TA option does not. The
DHCPv6 server uses T1 and T2 to control the time at which the client contacts with the server to
extend the lifetimes on any addresses in the IA_NA before the lifetimes expire. After T1, the client
sends the server (S1) (from which the addresses in the IA_NA were obtained) a Renew message. If
the time T2 is reached and the server does not respond, the client sends a Rebind message to any
available server (S2). For an IA_TA, the client may send a Renew or Rebind message at the client's
discretion.

DHCP Relay Agent
A DHCP relay agent is on the same network as the DHCP clients and helps forward messages
between the DHCP server and clients. When a client cannot use its link-local address and a wellknown multicast address to locate a DHCP server on its network, it then needs a DHCP relay agent
to send a message to a DHCP server that is not attached to the same network.
The DHCP relay agent can add the remote identification (remote-ID) option and the interface-ID
option to the Relay-Forward DHCPv6 messages. The remote-ID option carries a user-defined string,
1.
In IPv6, all network interfaces can be associated with several addresses.
NWA5000 / WAC6500 Series User’s Guide
204
Appendix B IPv6
such as the system name. The interface-ID option provides slot number, port information and the
VLAN ID to the DHCPv6 server. The remote-ID option (if any) is stripped from the Relay-Reply
messages before the relay agent sends the packets to the clients. The DHCP server copies the
interface-ID option from the Relay-Forward message into the Relay-Reply message and sends it to
the relay agent. The interface-ID should not change even after the relay agent restarts.
Prefix Delegation
Prefix delegation enables an IPv6 router to use the IPv6 prefix (network address) received from the
ISP (or a connected uplink router) for its LAN. The NWA/WAC uses the received IPv6 prefix (for
example, 2001:db2::/48) to generate its LAN IP address. Through sending Router Advertisements
(RAs) regularly by multicast, the NWA/WAC passes the IPv6 prefix information to its LAN hosts. The
hosts then can use the prefix to generate their IPv6 addresses.
ICMPv6
Internet Control Message Protocol for IPv6 (ICMPv6 or ICMP for IPv6) is defined in RFC 4443.
ICMPv6 has a preceding Next Header value of 58, which is different from the value used to identify
ICMP for IPv4. ICMPv6 is an integral part of IPv6. IPv6 nodes use ICMPv6 to report errors
encountered in packet processing and perform other diagnostic functions, such as "ping".
Neighbor Discovery Protocol (NDP)
The Neighbor Discovery Protocol (NDP) is a protocol used to discover other IPv6 devices and track
neighbor’s reachability in a network. An IPv6 device uses the following ICMPv6 messages types:
• Neighbor solicitation: A request from a host to determine a neighbor’s link-layer address (MAC
address) and detect if the neighbor is still reachable. A neighbor being “reachable” means it
responds to a neighbor solicitation message (from the host) with a neighbor advertisement
message.
• Neighbor advertisement: A response from a node to announce its link-layer address.
• Router solicitation: A request from a host to locate a router that can act as the default router and
forward packets.
• Router advertisement: A response to a router solicitation or a periodical multicast advertisement
from a router to advertise its presence and other parameters.
IPv6 Cache
An IPv6 host is required to have a neighbor cache, destination cache, prefix list and default router
list. The NWA/WAC maintains and updates its IPv6 caches constantly using the information from
response messages. In IPv6, the NWA/WAC configures a link-local address automatically, and then
sends a neighbor solicitation message to check if the address is unique. If there is an address to be
resolved or verified, the NWA/WAC also sends out a neighbor solicitation message. When the NWA/
WAC receives a neighbor advertisement in response, it stores the neighbor’s link-layer address in
the neighbor cache. When the NWA/WAC uses a router solicitation message to query for a router
and receives a router advertisement message, it adds the router’s information to the neighbor
cache, prefix list and destination cache. The NWA/WAC creates an entry in the default router list
cache if the router can be used as a default router.
When the NWA/WAC needs to send a packet, it first consults the destination cache to determine the
next hop. If there is no matching entry in the destination cache, the NWA/WAC uses the prefix list
NWA5000 / WAC6500 Series User’s Guide
205
Appendix B IPv6
to determine whether the destination address is on-link and can be reached directly without
passing through a router. If the address is onlink, the address is considered as the next hop.
Otherwise, the NWA/WAC determines the next-hop from the default router list or routing table.
Once the next hop IP address is known, the NWA/WAC looks into the neighbor cache to get the linklayer address and sends the packet when the neighbor is reachable. If the NWA/WAC cannot find an
entry in the neighbor cache or the state for the neighbor is not reachable, it starts the address
resolution process. This helps reduce the number of IPv6 solicitation and advertisement messages.
Multicast Listener Discovery
The Multicast Listener Discovery (MLD) protocol (defined in RFC 2710) is derived from IPv4's
Internet Group Management Protocol version 2 (IGMPv2). MLD uses ICMPv6 message types, rather
than IGMP message types. MLDv1 is equivalent to IGMPv2 and MLDv2 is equivalent to IGMPv3.
MLD allows an IPv6 switch or router to discover the presence of MLD listeners who wish to receive
multicast packets and the IP addresses of multicast groups the hosts want to join on its network.
MLD snooping and MLD proxy are analogous to IGMP snooping and IGMP proxy in IPv4.
MLD filtering controls which multicast groups a port can join.
MLD Messages
A multicast router or switch periodically sends general queries to MLD hosts to update the multicast
forwarding table. When an MLD host wants to join a multicast group, it sends an MLD Report
message for that address.
An MLD Done message is equivalent to an IGMP Leave message. When an MLD host wants to leave
a multicast group, it can send a Done message to the router or switch. The router or switch then
sends a group-specific query to the port on which the Done message is received to determine if
other devices connected to this port should remain in the group.
