NAC Appliance+WS-C4506-E - MAC notification problem
I'm trying to get working NAC Appliance 4.5 with WS-C4506-E with MAC notification without any luck. It seems that C4506 detects a MAC change, sends a SNMP trap to NAC Manager and according to what I was able to sniff directly on NAM via tcpdump it even arrives on NAM but I don't see it in Discovered Clients - it's like NAM ignores it completely. It doesn't see the change, therefore doesn't change VLAN on managed port of source switch.
Strangely enough, the same exact configuration does work on c3750 without a problem. I'm using NAC Applience 4.5 and WS-C4506-E with SUP4 and cat4500-ipbasek9-mz.122-46.SG.bin IOS image. It even works with WS-C4506-E in link-up link-down mode which sadly is insufficient for my case as I need IP phones to be connected to switch before the end user.
Can anyone here direct me where the problem should be?
Re: NAC Appliance+WS-C4506-E - MAC notification problem
sorry for late response. I solved this issue by upgrading IOS to 12.2(50)SG becouse of a SNMP Trap bug with 12.2(46)SG. I don't know if it's the same issue with your 12.2(31) but give it a try and you'll see.
