switch port in dot1x multi-auth mode stops passing traffic
I am experiencing a problem on a Catalyst 4510 (cat4500-ipbasek9-mz.122-53.SG.bin) with 802.1x configured. Client PCs are connected via a mini desktop switch to a Cat 4510 switched port in multi-auth mode. The configuration of the port follows:
! interface GigabitEthernet2/34 switchport mode access ip arp inspection limit rate 30 authentication host-mode multi-auth authentication port-control auto authentication periodic authentication timer reauthenticate server dot1x pae authenticator dot1x timeout tx-period 5 dot1x max-reauth-req 6 spanning-tree portfast ip verify source vlan dhcp-snooping end
It happens from time to time that the Cat 4510 port stops passing traffic. Reconnecting the mini switch recovers the communication. Client PCs connected to the mini switch seem to be authorized at the moment when the problem occures. The RADIUS Termination-Action attribute is set to RADIUS-Request. The problem is not present if "authentication periodic" is disabled.
Did anyone experience a simmilar problem? Any advice?
