Module: IEEE8021-BRIDGE-MIB

OID (symbolic): IEEE8021-BRIDGE-MIB::ieee8021BridgeBaseComponentType

OID (numeric): 1.3.111.2.802.1.1.2.1.1.1.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-create

Description: Indicates the component type(s) of this Bridge. The following component types are possible:

iComponent(1) - An S-VLAN component of a Backbone Edge Bridge which performs encapsulation of customer frames.

bComponent(2) - An S-VLAN component of a Backbone Edge Bridge which bundles backbone service instances into B-VLANs.

cVlanComponent(3) - A C-VLAN component of an enterprise VLAN Bridge or of a Provider Bridge used to process C-tagged frames.

sVlanComponent(4) - An S-VLAN component of a Provider Bridge.

dBridgeComponent(5) - A VLAN unaware component of an IEEE 802.1Q Bridge.

erComponent (6) - An Edge Relay component of an EVB Station.

tComponent (7) - A TPMR component in a Backbone Edge Bridge.

This object may not be modified while the corresponding instance of ieee8021BridgeBaseRowStatus is active(1).

The value of this object MUST be retained across reinitializations of the management system.

What is ieee8021BridgeBaseComponentType?

Identifies what kind of 802.1 bridge component this is, such as a plain VLAN-aware Bridge, a Provider Bridge S-VLAN or C-VLAN component, or a Backbone Edge Bridge's I- or B-component; this determines which encapsulation and tagging behavior the row implements.
