ieee8021CnCpMacAddress

Module: IEEE8021-CN-MIB

OID (symbolic): IEEE8021-CN-MIB::ieee8021CnCpMacAddress

OID (numeric): 1.3.111.2.802.1.1.18.1.5.1.5

Node type: OBJECT-TYPE

Type: MacAddress

Access: read-only

Description: This object indicates the MAC address used as the source address in Congestion Notification Message transmitted by this Congestion Point.

What is ieee8021CnCpMacAddress?

The source MAC address this Congestion Point stamps on the Congestion Notification Messages it transmits, which an admin can use to trace CNMs seen on the wire back to the CP that generated them.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.18.1.5.1.5
snmpwalk -v2c -c public <target> IEEE8021-CN-MIB::ieee8021CnCpMacAddress

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.18.1.5.1.5.1
snmpget -v2c -c public <target> IEEE8021-CN-MIB::ieee8021CnCpMacAddress.1
