## SYNOPSIS

```
    #Let SNMP::Info determine the correct subclass for you.
    my $airespace = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 2
                        )
    or die "Can't connect to DestHost.\n";
    my $class = $airespace->class();
    print " Using device sub class : $class\n";

## DESCRIPTION

Provides abstraction to the configuration information obtainable from Cisco (Airespace) Wireless Controllers through SNMP.

### Inherited Classes

- SNMP::Info::Airespace

  - SNMP::Info::CDP

  - SNMP::Info::Bridge

  ### Required MIBs

- *CISCO-LWAPP-DOT11-CLIENT-MIB*

  - *CISCO-LWAPP-DOT11-MIB*

  - *CISCO-LWAPP-AP-MIB*

  - Inherited Classes' MIBs

  See "Required MIBs" in SNMP::Info::Airespace for its own MIB requirements.

  See "Required MIBs" in SNMP::Info::CDP for its own MIB requirements.

  See "Required MIBs" in SNMP::Info::Bridge for its own MIB requirements.

## GLOBALS

These are methods that return scalar value from SNMP

- $airespace-\>**vendor()**

  Returns 'cisco'

- $airespace-\>**os()**

  Returns 'cisco'

- $airespace-\>**model()**

  (`"agentInventoryMachineModel"`)

### Global Methods imported from SNMP::Info::Airespace

See documentation in "GLOBALS" in SNMP::Info::Airespace for details.

### Global Methods imported from SNMP::Info::CDP

See documentation in "GLOBALS" in SNMP::Info::CDP for details.

### Globals imported from SNMP::Info::Bridge

See documentation in "GLOBALS" in SNMP::Info::Bridge for details.

## TABLE METHODS

These are methods that return tables of information in the form of a reference to a hash.

- **cd11\_mac()**

  Returns client radio interface MAC addresses.

- **cd11\_txrate()**

  Returns client transmission speed in Mbs.

### Overrides

- **i\_mac()**

  Adds AP Ethernet MAC as port mac on radio ports from `"CISCO-LWAPP-AP-MIB"`.

### Table Methods imported from SNMP::Info::Airespace

## Data Munging Callback Subroutines

- **munge\_cd11n\_ch\_bw()**

  Converts 802.11n channel bandwidth to either 20 or 40.

- **munge\_cd11\_proto()**

  Converts 802.11n 2.4Ghz to 1 and 5Ghz to 2 to correspond to the (`"cldHtMacOperationsTable"`) index.

- **munge\_cd11\_rateset()**

  Converts rate set to array.
