Will the RAP?s disconnect (IPSEC) when Process Auth is restarted

by on ‎11-11-2014 04:51 PM

Environment         All Aruba OS

 

Yes   It's  an expected behaviour since user table  in auth is reset. If we have a  backup-LMS  Raps will switched to that and IKE drop all IPSEC connections  to  configured backup-LMS,    However, RAPs will switch back to LMS automatically if lms-preemption in ap-system-profile is enabled .

 
Test Setup/ Outputs
================

Setup shows how the Ipsec session is terminated when the auth module is restarted.
