zxAnIfLoopbackUplinkCVid
Module: ZTE-AN-INTERFACE-LOOPBACK-MIB
OID (symbolic): ZTE-AN-INTERFACE-LOOPBACK-MIB::zxAnIfLoopbackUplinkCVid
OID (numeric): 1.3.6.1.4.1.3902.1082.30.38.2.1.2.1.4
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The CVLAN ID. when zxAnIfLoopbackUplinkEnable is disabled, zxAnIfLoopbackUplinkCVid is 0.
What is zxAnIfLoopbackUplinkCVid?
This value sets the Customer VLAN (CVLAN) ID (0-4094) used for the uplink loopback test traffic, the inner tag paired with the SVLAN ID; per the source description, it is forced to 0 whenever zxAnIfLoopbackUplinkEnable is disabled. A network technician sets this to match the CVLAN tag the uplink actually carries, so loopback testing reflects real double-tagged traffic conditions. For example, setting zxAnIfLoopbackUplinkCVid to 50 alongside a configured SVLAN sets up the loopback test to use the same double-VLAN-tag combination as live customer traffic.
