snSwIfInfoL2FowardEnable

Module: FOUNDRY-SN-SWITCH-GROUP-MIB

OID (symbolic): FOUNDRY-SN-SWITCH-GROUP-MIB::snSwIfInfoL2FowardEnable

OID (numeric): 1.3.6.1.4.1.1991.1.1.3.3.5.1.60

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The status of cluster L2 forward feature on an ethernet port. When this object is set to disable, the STP protocol packets coming on the MCT VLANs are dropped.

The snSwIfInfoL2FowardEnable has more preference than brcdMctL2Forward for this interface when set with enable(1) or disable(2). When set to globalConfig(3) the status of brcdMctL2Forward object applies for this interface.

What is snSwIfInfoL2FowardEnable?

This OID holds a flag controlling whether Layer 2 forwarding (data link switching) is enabled on a port in a clustered Foundry switch, with three modes: enable, disable, or follow global config. Changing it allows you to block or permit spanning tree protocol packets on cluster links. A network operator would disable this on problem MCT (Multi-Chassis Trunking) VLAN ports to prevent spanning tree loops or enable it to restore cluster connectivity.

Examples
