## DESCRIPTION

*IEEE8021-Q-BRIDGE-MIB* is used by some newer switches / Layer 2 devices. It is derived from the IETF Q-BRIDGE-MIB (RFC 4363), extending it with the concept of multiple VLAN-aware bridges (PBB).

Create or use a subclass of SNMP::Info that inherits this class.  Do not use directly.

For debugging you can call **new()** directly as you would in SNMP::Info

```
 my $bridge = new SNMP::Info::IEEE802_Bridge(...);
```

### Inherited Classes

None.

### Required MIBs

- *IEEE8021-Q-BRIDGE-MIB*

  ## GLOBALS

These are methods that return scalar values from SNMP

## TABLE METHODS

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

### Per-port VLAN configuration in the device ("ieee8021QBridgePortVlanTable")

- $bridge-\>**iqb\_i\_vlan()**

  (`"ieee8021QBridgePvid"`)

- $bridge-\>**iqb\_i\_vlan\_type()**

  (`"ieee8021QBridgePortAcceptableFrameTypes"`)

- $bridge-\>**iqb\_i\_vlan\_in\_flt()**

  (`"ieee8021QBridgePortIngressFiltering"`)

### VLAN Current Table ("ieee8021QBridgeVlanCurrentTable")

- $bridge-\>**iqb\_cv\_egress()**

  (`"ieee8021QBridgeVlanCurrentEgressPorts"`)

- $bridge-\>**iqb\_cv\_untagged()**

  (`"ieee8021QBridgeVlanCurrentUntaggedPorts"`)

- $bridge-\>**iqb\_cv\_stat()**

  (`"ieee8021QBridgeVlanStatus"`)

### VLAN Static Table ("ieee8021QBridgeVlanStaticTable")

- $bridge-\>**iqb\_v\_name()**

  (`"ieee8021QBridgeVlanStaticName"`)

- $bridge-\>**iqb\_v\_egress()**

  (`"ieee8021QBridgeVlanStaticEgressPorts"`)

- $bridge-\>**iqb\_v\_fbdn\_egress()**

  (`"ieee8021QBridgeVlanForbiddenEgressPorts"`)

- $bridge-\>**iqb\_v\_untagged()**

  (`"ieee8021QBridgeVlanStaticUntaggedPorts"`)

- $bridge-\>**iqb\_v\_stat()**
