cnIfVlanTrunk

Module: CENTILLION-IF-EXTENSIONS-MIB

OID (symbolic): CENTILLION-IF-EXTENSIONS-MIB::cnIfVlanTrunk

OID (numeric): 1.3.6.1.4.1.930.3.2.1.1.16

Node type: OBJECT-TYPE

Type: EnableIndicator

Access: read-write

Description: This object controls the VLAN trunk mode for the interface. In trunk mode, the interface accepts both tagged and untagged frames in its default VLAN. Trunk mode is only available for interfaces that support 802.1Q tagging, as indicated by cnIfVlanCapabilities. An interface in trunk mode cannot do protocol-based VLAN classification. The trunk mode cannot be changed while the interface belongs to an MLT group.

What is cnIfVlanTrunk?

This read-write setting controls whether an 802.1Q-capable interface operates in VLAN trunk mode, in which it accepts both tagged and untagged frames on its default VLAN.
