cmEthernetTrafficPortOuterVlanLoopback1

Module: CM-FACILITY-MIB

OID (symbolic): CM-FACILITY-MIB::cmEthernetTrafficPortOuterVlanLoopback1

OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.27.1.26

Node type: OBJECT-TYPE

Type: DisplayString

Access: read-write

Description: This object allows specification of the outer VLAN 1 to be looped back when port is in vlan(terminal/facility) loopback configuration. This is valid only if the corresponding bit in cmEthernetTrafficPortOuterVlanLoopbackMask is set. The value to be specified should be in the form X-Y where X is the VLAN Id and Y is the VLAN Priority. If Y is specified as a *, all Priorities (0 to 7) are looped back.

What is cmEthernetTrafficPortOuterVlanLoopback1?

cmEthernetTrafficPortOuterVlanLoopback1 is a read-write string specifying the outer VLAN 1 value to be looped back when the port is in VLAN loopback configuration, valid only if the corresponding bit in the loopback mask is set. An administrator enters the specific VLAN ID here to define exactly which tagged traffic is captured by the first of up to three VLAN loopback slots on this port. For example, to loop back only traffic tagged with outer VLAN 100, an operator would set this object to 100 and set the matching bit in cmEthernetTrafficPortOuterVlanLoopbackMask.
