cmEthernetAccPortOuterVlanLoopbackMask
Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmEthernetAccPortOuterVlanLoopbackMask
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.1.1.33
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description:
This object allows specification of the outer 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 Outer VLAN 1 Loopback Enabled 2 Outer VLAN 2 Loopback Enabled 4 Outer VLAN 3 Loopback Enabled Value of 0 means that no VLANs are enabled.
What is cmEthernetAccPortOuterVlanLoopbackMask?
This bitmask controls which of up to three outer VLAN IDs should be looped back when the Ethernet access port is configured for VLAN loopback testing, allowing technicians to create self-test configurations. Each bit position enables loopback for one of three possible outer VLANs; a value of 0 disables all loopback. Test engineers use this during port diagnostics and maintenance to verify VLAN handling.
