cnt2XIfPhysAddress
Module: CNT21-MIB
OID (symbolic): CNT21-MIB::cnt2XIfPhysAddress
OID (numeric): 1.3.6.1.4.1.333.2.1.2.3.1.9
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: The interface's address at the protocol layer immediately `below' the network layer in the protocol stack. For interfaces which do not have such an address (e.g., a serial line), this object should contain an octet string of zero length.
What is cnt2XIfPhysAddress?
This OCTET STRING holds the interface's hardware address for this extended-table row, or a zero-length string for media types like serial lines that don't have one. An administrator correlates a populated value here with switch CAM tables or ARP entries while tracing connectivity issues back to this specific card. For example, a nonempty cnt2XIfPhysAddress on this row lets the admin match it against a MAC address seen in a downstream switch's forwarding table.
