What is cucsDcxVcMacRegisterMode?

This controls how MAC addresses learned on this virtual circuit are registered with the fabric - for example only the vNIC's assigned MAC versus all MACs seen, which is needed for nested virtualization. An admin running a nested hypervisor or multiple VMs behind a single vNIC without VM-FEX needs this set to allow multiple registered MACs, otherwise traffic for any MAC other than the vNIC's own assigned address gets silently dropped by the fabric. A value of 'all-host' here would be required to let a nested ESXi host's VMs, each with distinct MACs, pass traffic through this single circuit.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.719.1.10.4.1.40
snmpwalk -v2c -c public <target> CISCO-UNIFIED-COMPUTING-DCX-MIB::cucsDcxVcMacRegisterMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.719.1.10.4.1.40.1
snmpget -v2c -c public <target> CISCO-UNIFIED-COMPUTING-DCX-MIB::cucsDcxVcMacRegisterMode.1
