cnt2IfPhysAddress
Module: CNT21-MIB
OID (symbolic): CNT21-MIB::cnt2IfPhysAddress
OID (numeric): 1.3.6.1.4.1.333.2.1.2.2.1.7
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 cnt2IfPhysAddress?
This OCTET STRING holds the interface's hardware address at the protocol layer immediately below the network layer, and is a zero-length string for interfaces like serial lines that have no such address. An administrator cross-references a populated value here with switch or ARP tables while tracing connectivity problems back to a specific card. For example, an empty cnt2IfPhysAddress on a given row confirms that interface is a serial-style link with no MAC address to look up.
