AP Configuration Interfaces
AP Configuration Interfaces
The following sections describe the configuration interfaces you can use to
access and configure BelAir Networks APs:
• “Command Line Interface” on page 21
• “SNMP Interface” on page 21
• “Web Interface” on page 24
All three interfaces (CLI, SNMP and Web) have the same public IP address. All
three also access the same AP database. That means that changes made with
one interface are seen immediately through the other interfaces.
Command Line
Interface
The CLI allows you to configure and display all the parameters of an AP,
including:
• system parameters
• system configuration and status
• radio module configuration and status
• user accounts
• traffic statistics
• layer 2 functionality, such as those related to bridging and VLANs
• Quality of Service parameters
• alarm system configuration and alarms history
Each AP can have up to nine simultaneous CLI sessions (Telnet or SSH). For a
description of basic CLI commands and tasks see “Command Line Interface
Basics” on page 27.
SNMP Interface
April 22, 2012
The Simple Network Management Protocol (SNMP) provides a means of
communication between SNMP managers and SNMP agents. The SNMP
manager is typically a part of a network management system (NMS) such as HP
OpenView, while the AP provides the services of an SNMP agent. Configuring
the AP SNMP agent means configuring the SNMP parameters to establish a
relationship between the manager and the agent.

AP Configuration Interfaces
The AP SNMP agent contains Management Information Base (MIB) variables. A
manager can query an agent for the value of MIB variables, or request the agent
to change the value of a MIB variable.
Refer to the following sections:
• “SNMP Configuration Guidelines” on page 42
• “SNMP Command Reference” on page 43
Integrating the AP with
a Pre-deployed NMS
In addition to providing support for the SNMP MIBs described in Table 3, BelAir
Networks provides a number of enterprise MIB definitions that you can
integrate with your Network Management System (NMS). Table 4 on page 23
describes the SNMP MIBs. A copy of the SNMP MIBs is available from the

Web Interface
BelAir Networks has verified that the AP Web interface operates correctly
with the following web browsers:
• Microsoft Internet Explorer version 6.0, service pack 2
• Mozilla Firefox version 1.5, or later
Accessing the Web
Interface
You can access the Web interface using either secure HTTP (HTTPS) or HTTP.
Both HTTP and HTTPS are enabled when each AP is shipped. Each AP can have
up to five simultaneous CLI sessions (HTTP or HTTPS).
By default, the AP Web interface has an associated time-out value. If the
interface is inactive for 9 minutes, then you are disconnected from the
interface. To reconnect to the interface, you need to log in again.

• “Common CLI Commands” on page 38
Connecting to the
AP
You can connect to the AP default address using one of the following methods:
• through the AP radio interface
• by connecting directly to the Ethernet port on the AP
• by connecting through the cable modem, if it is equipped with one
CAUTION!
Do not connect the AP to an operational data network before you configure its
desired IP network parameters. This may cause traffic disruptions due to
potentially duplicated IP addresses.
The AP must connect to an isolated LAN, or to a desktop or laptop PC
configured to communicate on the same IP sub-network as the AP.
Using the Radio Interface
Use a desktop or laptop PC equipped with a wireless 802.11a, 802.11b, 802.11g
or 802.11n compliant interface as required, configured with a static IP address
on the same subnet as the default OAM IP address (for example, 10.1.1.1/24).
For the required configuration procedure, refer to your PC and wireless
interface configuration manuals or contact your network administrator. The PC
will connect to the AP through the radio interface.
Connecting to the Ethernet Port
Use a cross-connect RJ45 cable to connect the Ethernet port of the AP.
Using the Cable Modem
The MAC address for the AP’s cable modem should have been supplied to your
System Administrator when the AP was installed so that an IP address could be

assigned to it. Contact your system administrator to determine the IP address
to use.
For a detailed procedure, refer to the AP Installation Guide.
Starting a CLI
Session
Start a Telnet or secure shell (SSH) client and connect to the AP‘s IP address. If
you are configuring the AP for the first time, you must use the default IP
address (10.1.1.10). The AP prompts you for your user name and password.
The default super-user account is “root”. The default password is “admin123”.
If the login is successful, the AP CLI prompt is displayed. The default prompt is
“#”, if you login as root. Otherwise, the default prompt string is “>”.
Note 1: The terminal session locks after four unsuccessful login attempts. To
unlock the terminal session, you must enter the super-user password.
Note 2: CLI commands are not case sensitive (uppercase and lowercase
characters are equivalent). However, some command parameters are
case sensitive. For example, passwords and any Service Set Identifier
(SSID) supplied with the radio commands are case sensitive. Also, all
parameters of the syscmd commands are case sensitive.
Note 3: Later, you will see that you can configure the AP to have more than
one interface with an IP address. For example, you can configure
Virtual LANs and management interfaces each with their own IP
address. If you do this, make sure your Telnet or secure shell (SSH)
connections are to a management interface. This ensures maximum
responsiveness for your session by keeping higher priority management
IP traffic separate from other IP traffic.

Command Modes
The CLI has different configuration “modes”. Different commands are available
to you, depending on the selected mode.
Each card in the AP has at least one associated physical interface. Some
examples of physical interfaces are a Wi-Fi radio or an Ethernet interface.
Use the mode command to display the modes that are available. Because each
physical interface and each card in the AP has its own mode, displaying the
modes also displays a profile summary of the AP. See Figure 11.

Note 1: The prompt changes to match the current mode. You can further
customize the prompt to show the switch name or a 20-character
string that you define.
Note 2: Access to a mode is only allowed if the user has sufficient privileges to
execute commands in that mode.
When you access a given mode, only the commands pertaining to that mode
are available. For example, accessing snmp mode provides access to SNMP
commands. For a physical interface, this means that only the commands that
apply to that specific type and version of interface are available when you access
a particular physical interface. For example, if you access an HTMEv1 interface,
only the commands that apply to an HTMEv1 Wi-Fi radio are available.
Entering ? displays the commands that apply to the currently accessed mode.
Entering ?? or help displays the commands that apply to the currently accessed
mode plus common commands that are available in all modes.
Users may execute commands from other modes than the current one, by
prefixing the desired command with the slash character ‘/’ followed by the
mode’s name. For instance, entering:
