Module: CISCO-VOICE-CONNECTIVITY-MIB
OID (symbolic): CISCO-VOICE-CONNECTIVITY-MIB::cvcPortMACAddress
OID (numeric): 1.3.6.1.4.1.9.9.393.1.2.1.1.6
Node type: OBJECT-TYPE
Type: MacAddress
Access: read-only
Description: This object indicates the MAC address of the port. For ports which do not have such an address, this object should contain an octet string of zero length.
What is cvcPortMACAddress?
This is a read-only field holding the MAC address of the voice port, or a zero-length octet string for ports that don't have a MAC address. An admin uses this to identify the physical network interface of an endpoint, which is useful for cross-referencing with switch port security tables or DHCP lease records. For example, tracking down which switch port a misbehaving IP phone is plugged into often starts with this MAC address.
