According to
Command Reference, Cisco IOS XE Fuji 16.9.x (Catalyst 3850 Switches) - Stack Manager and High Availability [Cisco Catalyst 3850 Series Switches] - Cisco
I can use "session" command to access the diagnostic shell of a specific stack member. I am trying to get the output of "sh ver" command of switch in standby state. What I need is to check "Last reload reason" string after stack switchover (and reload)
%REDUNDANCY-3-SWITCHOVER: RP switchover (PEER_DOWN)
%REDUNDANCY-3-SWITCHOVER: RP switchover (PEER_REDUNDANCY_STATE_CHANGE)
%STACKMGR-4-SWITCH_REMOVED: Switch 2 R0/0: stack_mgr: Switch 1 has been removed from the stack.
also, "To enable debugging on the standby switch without first starting a session on the active switch, use the remote command switch-number LINE command in privileged EXEC mode"
