Environment
  • EXOS version 22.x
  • Netlogin MAC authentication
  • NetSight, NAC version 7.x
  • Radius
  • Policy VLAN assignment
Cause
The addition of the following type of command will cause authenticated sessions to be terminated; after 300 seconds in this example
configure netlogin session-timeout mac 300

 
Resolution
  • Configure the required value for an authenticated session
  • Do not add a session timeout if not required since the default value is 0 which is no timeout
  • If session timeout is required decide wether to configure it on the switch or the Radius server
