cwvlBridgingNativeVlanId
Module: CISCO-WLAN-VLAN-MIB
OID (symbolic): CISCO-WLAN-VLAN-MIB::cwvlBridgingNativeVlanId
OID (numeric): 1.3.6.1.4.1.9.9.268.1.1.2
Node type: OBJECT-TYPE
Type: CwvlVlanIdOrZero
Access: read-write
Description: This object specifies the native VLAN ID for layer 2 bridging. If this object is set to '0', there is no layer 2 bridging native VLAN ID. Setting this object will automatically update the dot1qPvid for all interfaces in the Q-BRIDGE-MIB (if supported) to the same value provided it is not '0'. The dot1qPvid will be read-only. The dot1qPvid specifies the native VLAN ID on each device interface. If this object is '0', the return value of dot1qPvid is not valid.
If the device is attached to a VLAN port of an Ethernet bridge or switch, then the device must have a non-zero native VLAN ID, and that VLAN ID must also match the VLAN ID of the port on the bridge or switch. The native VLAN ID is the default VLAN ID for frames received that are not otherwise associated with a VLAN ID.
What is cwvlBridgingNativeVlanId?
This read-write object sets the native (untagged) VLAN ID used for layer-2 bridging on the device, with a value of 0 meaning no native VLAN is configured. Per the desc, setting a non-zero value here automatically propagates to the dot1qPvid object for all interfaces in the Q-BRIDGE-MIB, which then becomes read-only there. For example, an admin standardizing native VLAN handling across a wireless bridge would set cwvlBridgingNativeVlanId once rather than configuring dot1qPvid separately on every interface.
