Description: Cisco UCS vnic:MacHistory:oldaddr managed object property
What is cucsVnicMacHistoryOldaddr?
This OID reports the previous MAC address (MacAddress) that this vNIC used before its current address was assigned. Recording the old MAC lets an admin diagnose issues where upstream switches, DHCP reservations, or firewall rules still reference the vNIC's former address after a pool re-assignment. After a MAC pool re-assignment causes a DHCP lease conflict, an admin checks this OID to retrieve the old MAC and update the DHCP reservation to the new one.
