OID (numeric): 1.3.6.1.4.1.9.9.719.1.52.12.1.21

Access: read-only

Description: Cisco UCS vm:Vlan:assocPrimaryVlanState managed object property

What is cucsVmVlanAssocPrimaryVlanState?

This read-only CucsFabricVlanAssocPrimaryVlanState value reports the operational state of the primary VLAN associated with this VM-FEX VLAN instance, for VLANs configured as secondary/private VLANs. Private-VLAN secondary VLANs only work correctly if their associated primary VLAN is also up, so this field lets an admin confirm the primary side of the pairing is healthy before assuming a VM's VLAN connectivity problem lies elsewhere. For a VM-FEX VLAN entry for VLAN 130 (the vMotion network) shared across two fabric interconnects configured as a secondary VLAN, this OID reporting the primary VLAN as down would immediately explain why VMs on the secondary VLAN have lost connectivity.
