Description: The number of MKPDUs received with MKA not enabled or CKN not recognized in this PAE.

What is ieee8021XEapolMkNoCknFramesRx?

A packet counter of MKPDUs (MKA protocol messages) received on this port where MKA wasn't enabled or the CKN (key name) wasn't recognized; a growing count suggests a peer is trying to run MKA with a key this PAE doesn't have cached, which is worth investigating as a possible key-provisioning mismatch.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.15.1.5.1.1.9
snmpwalk -v2c -c public <target> IEEE8021X-PAE-MIB::ieee8021XEapolMkNoCknFramesRx

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.15.1.5.1.1.9.1
snmpget -v2c -c public <target> IEEE8021X-PAE-MIB::ieee8021XEapolMkNoCknFramesRx.1
