I 'm trying to work with the NAC module and have no luck. Cisco 2811 does not recognize the module and I see the following error:
service-module integrated-Service-Engine 1/0 status
Service Module is Cisco Integrated-Service-Engine1/0
Service Module supports session via TTY line 66
Service Module is waiting for registration message
Service Module heartbeat-reset is enabled
Service Module is in fail open
I'm runing 12.4(20)T image
