Hi All,
I am currently implementing OnConnect Enforcement in my lab environment and it's working relatively well. I am however having some intermittent issues with our NEC DT700 series VoIP phones. OnConnect successfully categorizes the phone and applies the correct role and enforcement profile, however when I look through the alerts tab in the access tracker I get the following:
SNMP Service: MAC address lookup failed for host=00-60-b9-8b-1a-98
Enforcement failed
As a result, no port change/reset is requested via SNMP to the switch. In this case, it is an Aruba 2920 running 16.06 firmware. ClearPass is on 6.7.0.
I can change the port and sometimes it will work successfully, without any further changes to configuration.
Any ideas? Many thanks.
