cmEthernetAccPortInnerVlanLoopbackMask
Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmEthernetAccPortInnerVlanLoopbackMask
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.1.1.37
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object allows specification of the inner VLANs to be looped back when port is in vlan(terminal/facility) loopback configuration. Only 3 VLANs can be specified for vlan loopback. The various bit positions are: 1 Inner VLAN 1 Loopback Enabled 2 Inner VLAN 2 Loopback Enabled 4 Inner VLAN 3 Loopback Enabled Value of 0 means that no VLANs are enabled.
What is cmEthernetAccPortInnerVlanLoopbackMask?
This OID is a bitmask (a set of on/off switches) that determines which inner VLANs should loop back traffic when testing the port. Loopback means traffic is sent back to where it came from, used for diagnostics; you can enable up to 3 VLANs at a time. A network technician would use this when testing a physical port to verify it correctly handles multiple VLAN traffic without errors.
