Chapter 3 Configuring Ports and Interfaces

Configuring Multiple AP-Manager Interfaces

Using the CLI to Create Multiple AP-Manager Interfaces

To create multiple AP-manager interfaces using the controller CLI, follow these steps:

Step 1 Enter these commands to create a new interface:

• config interface create operator_defined_interface_name {vlan_id | x}

• config interface address operator_defined_interface_name ip_addr ip_netmask [gateway]

• config interface vlan operator_defined_interface_name {vlan_id | 0}

• config interface port operator_defined_interface_name physical_ds_port_number

• config interface dhcp operator_defined_interface_name ip_address_of_primary_dhcp_server

[ip_address_of_secondary_dhcp_server]

• config interface quarantine vlan interface_name vlan_id

Note Use this command to configure a quarantine VLAN on any interface.

• config interface acl operator_defined_interface_name access_control_list_name

Note See Chapter 6, “Configuring Security Solutions,” for more information on ACLs.

Step 2 To make this interface an AP-manager interface, enter this command:

config interface ap-manager operator_defined_interface_name {enable | disable}

Note Only one AP-manager interface is allowed per physical port. A dynamic interface that is marked

as an AP-manager interface cannot be used as a WLAN interface.

Step 3 To save your changes, enter this command:

save config

Step 4 Repeat this procedure for each additional AP-manager interface that you want to create.

Cisco 5500 Series Controller Example

For a Cisco 5500 Series Controller, we recommend having eight dynamic AP-manager interfaces and

associating them to the controller’s eight Gigabit ports. If you are using the management interface, which

acts like an AP-manager interface by default, you need to create only seven more dynamic AP-manager

interfaces and associate them to the remaining seven Gigabit ports. For example, Figure 3-20 shows a

dynamic interface that is enabled as a dynamic AP-manager interface and associated to port number 2,

and Figure 3-21 shows a Cisco 5500 Series Controller with LAG disabled, the management interface

used as one dynamic AP-manager interface, and seven additional dynamic AP-manager interfaces, each

mapped to a different Gigabit port.

Chapter 3 Configuring Ports and Interfaces

Configuring VLAN Select

Whenever a wireless client connects to a wireless network (WLAN), the client is placed in a VLAN that

is associated with the WLAN. Release 7.0.116.0 and prior releases of the controller software enabled

you to associate one VLAN with a WLAN. Each VLAN required a single IP subnet. As a result, a WLAN

required a large subnet to accommodate more clients. In a large venue such as an auditorium, a stadium,

or a conference where there may be numerous wireless clients, having only a single WLAN to

accommodate many clients might be a challenge.

The VLAN select feature enables you to use a single WLAN that can support multiple VLANs. Clients

can get assigned to one of the configured VLANs. This feature enables you to map a WLAN to a single

or multiple interface VLANs using interface groups. Wireless clients that associate to the WLAN get an

IP address from a pool of subnets identified by the interfaces in round-robin fashion. This feature also

extends the current AP group architecture where AP groups can override an interface or interface group

to which the WLAN is mapped to, with multiple interfaces using the interface groups. This feature also

provides the solution to auto anchor restrictions where a wireless guest user on a foreign location can

get an IP address from multiple subnets based on their foreign locations or foreign controllers from the

same anchor controller.

When a client roams from one controller to another, the foreign controller sends the VLAN information

as part of the mobility announce message. Based on the VLAN information received, the anchor decides

whether the tunnel should be created between the anchor controller and the foreign controller. If the

same VLAN is available on the foreign controller, the client context is completely deleted from the

anchor and the foreign controller becomes the new anchor controller for the client.

If an interface (int-1) in a subnet is untagged in one controller (Vlan ID 0) and the interface (int-2) in

the same subnet is tagged to another controller (Vlan ID 1), then with the VLAN select, client joining

the first controller over this interface may not undergo an L2 roam while it moves to the second

controller. Hence, for L2 roaming to happen between two controllers with VLAN select, all the

interfaces in the same subnet should be either tagged or untagged.

As part of the VLAN select feature, the mobility announce message carries an additional vendor payload

that contains the list of VLAN inte rfaces in an interface group mapped to a foreign controller’s WLAN.

This VLAN list enables the anchor to differentiate from a local to local or local to foreign handoff.

Note VLAN pooling applies to wireless clients and locally switched WLANs.

Chapter 3 Configuring Ports and Interfaces

Configuring VLAN Select

Using Interface Groups

Interface groups are logical groups of interfaces. Interface groups facilitate user configuration where the

same interface group can be configured on multiple WLANs or while overriding a WLAN interface per

AP group. An interface group can exclusively contain either quarantine or nonquarantine interfaces. An

interface can be part of multiple interface groups.

A WLAN can be associated with an interface or interface group. The interface group name and the

interface name cannot be the same.

This feature also enables you to associate a client to specific subnets based on the foreign controller that

they are connected to. The anchor controller WLAN can be configured to maintain a mapping between

foreign controller MAC and a specific interface or interface group (Foreign maps) as needed. If this

mapping is not configured, clients on that foreign controller gets VLANs associated in a round robin

fashion from interface group configured on WLAN.

Table 3-8 lists the platform support for interface and interface groups:

Step 4 Click Apply.

Using the CLI to Add an Interface Group to a WLAN

To add an interface group to a WLAN, use the command config wlan interface wlan_id

interface_group_name.

Using Multicast Optimization

Prior to the 7.0.116.0 release, multicast was based on the grouping of the multicast address and the

VLAN as one entity, MGID. With VLAN select and VLAN pooling, there is a possibility that you might

increase duplicate packets. With the VLAN select feature, every client listens to the multicast stream on

a different VLAN. As a result, the controller creates different MGIDs for each multicast address and

VLAN. Therefore, the upstream router sends one copy for each VLAN, which results, in the worst case,

in as many copies as there are VLANs in the pool. Since the WLAN is still the same for all clients,

multiple copies of the multicast packet are sent over the air. To suppress the duplication of a multicast

stream on the wireless medium and between the controller and access points, you can use the multicast

optimization feature.

Multicast optimization enables you to create a multicast VLAN which you can use for multicast traffic.

You can configure one of the VLANs of the WLAN as a multicast VLAN where multicast groups are

registered. Clients are allowed to listen to a multicast stream on the multicast VLAN. The MGID is

generated using mulicast VLAN and multicast IP addresses. If multiple clients on the VLAN pool of the

same WLAN are listening to a single multicast IP address, a single MGID is generated. The controller

makes sure that all multicast streams from the clients on this VLAN pool always go out on the multicast

VLAN to ensure that the upstream router has one entry for all the VLANs of the VLAN pool. Only one

multicast stream hits the VLAN pool even if the clients are on different VLANs. Therefore, the multicast

packets that are sent out over the air is just one stream.

Using the GUI to Configure a Multicast VLAN

Installing and Configuring Licenses

You can order Cisco 5500 Series Controllers with support for 12, 25, 50, 100, 250 or 500 access points

as the controller’s base capacity. You can add additional access point capacity through capacity adder

licenses available at 25, 50, 100 and 250 access point capacities. You can add the capacity adder licenses

to any base license in any combination to arrive at the maximum capacity of 500 access points. The base

and adder licenses are supported through both rehosting and RMAs.

Note These controller platforms do not require licenses: Cisco 2100 and Cisco 4400 Series Controllers, Cisco

WiSMs, Controller Network Modules, and Catalyst 3750G Integrated Wireless LAN Controller

Switches.

Note All features included in a Wireless LAN Controller Wplus license are now included in the base license;

this change is introduced in release 6.0.196.0. There are no changes to WCS BASE and PLUS licensing.

The base license supports the standard base software set and, for releases 6.0196.0 and later, the

premium software set is included as part of the base feature set, which includes this functionality:

• Datagram Transport Layer Security (DTLS) data encryption for added security across remote WAN

and LAN links. See the “Configuring Data Encryption” section on page 8-2 for more information

on data encryption.

Note The Availability of data DTLS for the 7.0.116.0 release is as follows:

Cisco 5500 Series Controller—The Cisco 5500 Series Controller will be available with two licensing

options: One with data DTLS capabilities and another image without data DTLS.

2500, WiSM2, WLC2—These platforms by default will not contain DTLS. To turn on data DTLS, you

must install a license. These platforms will have a single image with data DTLS turned off. To use data

DTLS you will need to have a license.

• Support for OfficeExtend access points, which are used for secure mobile teleworking. See the

“OfficeExtend Access Points” section on page 8-69 for more information on OfficeExtend access

points.

• Support for the 1130AG and 1240AG series indoor mesh access points, which dynamically establish

wireless connections in locations where it might be difficult to connect to the wired network. See

Chapter 9, “Controlling Mesh Access Points,” for more information on mesh access points.

All features included in a Wireless LAN Controller WPLUS license are now included in the base license;

this change is introduced in release 6.0.196.0. There are no changes to WCS BASE and PLUS licensing.

These WPlus license features are included in the base license:

• OfficeExtend AP

• Enterprise Mesh

• CAPWAP Data Encryption

Chapter 4 Configuring Controller Settings

Installing and Configuring Licenses

The licensing change can affect features on your wireless LAN when you upgrade or downgrade

software releases, so you should be aware of these guidelines:

• If you have a WPlus license and you upgrade from 6.0.x.x to 7.0.98.0, your license file contains both

Basic and WPlus license features. You won’t see any disruption in feature availability and operation.

• If you have a WPlus license and you downgrade from 7.0.98.0 to 6.0.196.0 or 6.0.188 or 6.0.182,

your license file contains only base license, and you will lose all WPlus features.

• If you have a base license and you downgrade from 6.0.196.0 to 6.0.188 or 6.0.182, when you

downgrade, you lose all WPlus features.

To view the controller trap log, choose Monitor and click View All under “Most Recent Traps” on the

controller GUI (see Figure 4-1).

Note You can also view traps by using SNMP-based management tools.

Figure 4-1 Trap Logs Page

The ap-count licenses and their corresponding image-based licenses are installed together. The

controller keeps track of the licensed access point count and does not allow more than the number of

access points to associate to it.

The Cisco 5500 Series Controller is shipped with both permanent and evaluation base and base-ap-count

licenses. If desired, you can activate the evaluation licenses, which are designed for temporary use and

set to expire after 60 days.

Note See the “Choosing the Licensed Feature Set” section on page 4-14 for instructions on activating an

image-based evaluation license and the “Activating an AP-Count Evaluation License” section on

page 4-17 for instructions on activating an ap-count evaluation license.

No licensing steps are required after you receive your Cisco 5500 Series Controller because the licenses

you ordered are installed at the factory. In addition, licenses and product authorization keys (PAKs) are

preregistered to serial numbers. However, as your wireless network evolves, you might want to add

support for additional access points or upgrade from the standard software set to the base software set.

To do so, you need to obtain and install an upgrade license.

Obtaining an Upgrade or Capacity Adder License

A certificate with a product authorization key (PAK) is required before you can obtain an upgrade

license.

OL-21524-02

Chapter 4 Configuring Controller Settings

Installing and Configuring Licenses

You can use the capacity adder licenses to increase the number of access points supported by the

controller up to a maximum of 500 access points. The capacity adder licenses are available in access

point capacities of 10, 25, 50, 100 and 250 access points. You can add these licenses to any of the base

capacity licenses of 12, 25, 50, 100 and 250 access points.

For example, if your controller was initially ordered with support for 100 access points (base license

AIR-CT5508-100-K9), you could increase the capacity to 500 access points by purchasing a 250 access

point, 100 access point, and a 50 access point additive capacity license (LIC-CT5508-250A,

LIC-CT5508-100A, and LIC-CT5508-50A).

You can find more information on ordering capacity adder licenses at this URL:

http://www.cisco.com/en/US/products/ps10315/products_data_sheets_list.html

Note If you skip any tiers when upgrading (for example, if you do not install the -25U and -50U licenses along

with the -100U), the license registration fails.

For a single controller, you can order different upgrade licenses in one transaction (for example, -25U,

-50U, -100U, and -250U), for which you receive one PAK with one license. Then you have only one

license (instead of four) to install on your controller.

If you have multiple controllers and want to upgrade all of them, you can order multiple quantities of

each upgrade license in one transaction (for example, you can order 10 each of the -25U, -50U, -100U,

and -250 upgrade licenses), for which you receive one PAK with one license. You can continue to register

the PAK for multiple controllers until it is exhausted.

Base license SKUs for the Cisco 5500 Series Controllers are as follows:

• AIR-CT5508-12-K9

• AIR-CT5508-25-K9

• AIR-CT5508-50-K9

• AIR-CT5508-100-K9

• AIR-CT5508-250-K9

• AIR-CT5508-500-K9

Base license SKUs for the Cisco 2500 Series Controllers are as follows:

• AIR-CT2504-5-K9

• AIR-CT2504-15-K9

• AIR-CT2504-25-K9

• AIR-CT2504-50-K9

Base license SKUs for the Cisco WiSM2 Controllers are as follows:

• WS-SVC-WISM2-1-K9—WiSM2 with 100 AP support.

• WS-SVC-WISM2-3-K9—WiSM2 with 300 AP support

Step 2 If you are ordering online, begin by choosing the primary upgrade SKU L-LIC-CT5508-UPG or LIC

CT5508-UPG. Then, choose any number of the following options to upgrade one or more controllers

under one PAK. Table 4-1 lists the capacity adder licenses available through e-mail or on paper:After

you receive the certificate, use one of two methods to register the PAK:

• Cisco License Manager (CLM)—This method automates the process of obtaining licenses and

deploying them on Cisco devices. For deployments with more than five controllers, we recommend

using CLM to register PAKs and install licenses. You can also use CLM to rehost or RMA a license.

Note You cannot use CLM to change the licensed feature set or activate an ap-count evaluation

license. To perform these operations, you must follow the instructions in the “Choosing the

Licensed Feature Set” section on page 4-14 and the “Activating an AP-Count Evaluation

License” section on page 4-17. Because you can use CLM to perform all other license

operations, you can disregard the remaining licensing information in this chapter except

these two sections and the “Configuring the License Agent” section on page 4-26 if you

want your controller to use HTTP to communicate with CLM.

Note You can download the CLM software and access user documentation at this URL:

http://www.cisco.com/go/clm

• Licensing portal—This alternative method enables you to manually obtain and install licenses on

your controller. If you want to use the licensing portal to register the PAK, follow the instructions

in Step 3.

Step 3 Use the licensing portal to register the PAK as follows:

a. Go to http://tools.cisco.com/SWIFT/Licensing/PrivateRegistrationServlet

b. On the main Product License Registration page, enter the PAK mailed with the certificate in the

Product Authorization Key (PAK) text box and click Submit.

c. On the Validate Features page, enter the number of licenses that you want to register in the Qty text

box and click Update.

d. To determine the controller’s product ID and serial number, choose Controller > Inventory on the

controller GUI or enter the show license udi command on the controller CLI.

Information similar to the following appears on the controller CLI:

Device# PID SN UDI

------- -------------------- ----------------------- ---------------------------------

*0 AIR-CT5508-K9 FCW1308L030 AIR-CT5508-K9:FCW1308L030

e. On the Designate Licensee page, enter the product ID and serial number of the controller on which

you plan to install the license, read and accept the conditions of the end-user license agreement

(EULA), complete the rest of the text boxes on this page, and click Submit.

f. On the Finish and Submit page, verify that all information is correct and click Submit.

g. When a message appears indicating that the registration is complete, click Download License. The

license is e-mailed within 1 hour to the address that you specified.

h. When the e-mail arrives, follow the instructions provided.

i. Copy the license file to your TFTP server.

Choosing the Licensed Feature Set

You can configure the controller to specify which feature set it uses (base or wplus). Only the base or

wplus license can be active at a time. The currently active license determines the feature set and number

of access points supported on the controller.

Using the GUI to Choose the Licensed Feature Set

To specify the feature set for the controller using the controller GUI, follow these steps:

Step 1 Choose Management > Software Activation > License Level to open the License Level page (see

Figure 4-6).

4-15

Cisco Wireless LAN Controller Configuration Guide

OL-21524-02

Chapter 4 Configuring Controller Settings

shows the maximum number of access points allowed by the license on the controller, the number of

access points currently joined to the controller, and the number of access points that can still join the

controller.

Step 2 Click the base license level link to open the Licenses page (see Figure 4-7) to learn more about the

available license levels.

Figure 4-7 Licenses Page

This page shows the licenses applicable to this level and the list of features supported.

Step 3 Click Back to return to the License Level page.

Step 4 If you want to change the license level, follow these steps:

a. Choose the license level to be used on the next reboot: base, wplus, or auto. If you choose auto, the

licensing software automatically chooses the license level to use on the next reboot. It chooses

permanent licenses over evaluation licenses.

4-16

Cisco Wireless LAN Controller Configuration Guide

OL-21524-02

Chapter 4 Configuring Controller Settings

Installing and Configuring Licenses

Note To prevent disruptions in operation, the controller does not switch licenses when an

evaluation license expires. You must reboot the controller in order to return to a permanent

license. Following a reboot, the controller defaults to the same feature set level as the expired

evaluation license. If no permanent license at the same feature set level is installed, the

controller uses a permanent license at another level or an unexpired evaluation license. If no

valid licenses are installed, the controller can always operate in base level.

b. Click Activate.

c. Click OK when prompted to confirm your decision to change the license level on the next reboot.

d. If you are prompted to accept the end-user license agreement (EULA), read and accept the terms of

the agreement and then click Accept. The Next Boot Level text box now shows the license level that

you specified as the level to be used after the next controller reboot.

e. Reboot the controller so that the specified license level takes effect.

Using the CLI to Choose the Licensed Feature Set

To specify the feature set for the controller using the controller CLI, follow these steps:

Step 1 See the current license level and the level to be used after the next controller reboot by entering this

command:

show sysinfo

Information similar to the following appears:

Product Name..................................... Cisco Controller

Product Version.................................. 6.0.118.0

...

Current Boot License Level....................... wplus

Current Boot License Type........................ Permanent

Next Boot License Level.......................... wplus

Next Boot License Type........................... Permanent

...

Step 2 Specify the license level to be used on the next reboot by entering this command:

config license boot {base | wplus | auto}

If you choose auto, the licensing software automatically chooses the license level to use on the next

reboot. It chooses permanent licenses over evaluation licenses.

Note To prevent disruptions in operation, the controller does not switch licenses when an evaluation

license expires. You must reboot the controller in order to return to a permanent license.

Following a reboot, the controller defaults to the same feature set level as the expired evaluation

license. If no permanent license at the same feature set level is installed, the controller uses a

permanent license at another level or an unexpired evaluation license.

Step 3 If you are prompted to accept the end-user license agreement (EULA), read and accept the terms of the

agreement. The EULA appears if no permanent licenses are installed at the specified boot level and the

evaluation license has not yet been activated. In this case, the config license boot command changes the

license level and activates the evaluation license following a reboot.

Step 5 Reboot the controller in order to have your changes take effect by entering this command:

reset system

Activating an AP-Count Evaluation License

If you are considering upgrading to a license with a higher access point count, you can try an evaluation

license before upgrading to a permanent version of the license. For example, if you are using a permanent

license with a 50-access-point count and want to try an evaluation license with a 100-access-point count,

you can try out the evaluation license for 60 days.

AP-count evaluation licenses are set to low priority by default so that the controller uses the ap-count

permanent license. If you want to try an evaluation license with an increased access point count, you

must change its priority to high. If you no longer want to have this higher capacity, you can lower the

priority of the ap-count evaluation license, which forces the controller to use the permanent license.

Note To prevent disruptions in operation, the controller does not switch licenses when an evaluation license

expires. You must reboot the controller in order to return to a permanent license. Following a reboot, the

controller defaults to the same feature set level as the expired evaluation license. If no permanent license

at the same feature set level is installed, the controller uses a permanent license at another level or an

unexpired evaluation license.

You can activate ap-count evaluation licenses using the controller GUI or CLI.

Using the GUI to Activate an AP-Count Evaluation License

To activate an ap-count evaluation license using the controller GUI, follow these steps:

Step 1 Choose Management > Software Activation > Licenses to open the Licenses page (see Figure 4-8).

Rehosting a License

Revoking a license from one controller and installing it on another is called rehosting. You might want

to rehost a license in order to change the purpose of a controller. For example, if you want to move your

OfficeExtend or indoor mesh access points to a different controller, you could transfer the base license

from one controller to another.

In order to rehost a license, you must generate credential information from the controller and use it to

obtain a permission ticket to revoke the license from the Cisco licensing site. Next, you must obtain a

rehost ticket and use it to obtain a license installation file for the controller on which you want to install

the license.

Evaluation licenses and the permanent base image license cannot be rehosted.

Note A revoked license cannot be reinstalled on the same controller.
