cmEthernetTrafficPortInnerVlanLoopback3
Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmEthernetTrafficPortInnerVlanLoopback3
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.27.1.87
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-write
Description: This object allows specification of the inner VLAN 3 to be looped back when port is in vlan(terminal/facility) loopback configuration. This is valid only if the corresponding bit in cmEthernetTrafficPortInnerVlanLoopbackMask 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 cmEthernetTrafficPortInnerVlanLoopback3?
This object configures the third inner VLAN that will be looped back to the same port during testing, specified as VLAN-ID and priority level pair (e.g., '100-5' for VLAN 100 with priority 5). Loopback is only active when the port is in VLAN loopback mode and the corresponding bit in the loopback mask is enabled. Test engineers use this setting to verify port functionality and VLAN processing by returning traffic back to the source without external connections.
