What is cmIpInterfacePhysicalAddress?
This read-only field reports the physical (MAC) address associated with this IP interface's address, per its description. Admins reference it when correlating Layer 3 configuration with the underlying Layer 2 hardware address, useful for cross-checking against switch MAC tables or ARP entries. For example, when tracing which physical NIC corresponds to a management IP interface, an admin would read this object to get the MAC address to search for in upstream switch tables.
