3850 Stack - "Authorization Failed" from Console

GRANT3779 · ‎02-01-2015

Hello,

I have a stack of 3 x 3850s. All connected up via the stack cables. I have the Primary Active Switch, The Standby and Member.

When I connect a console cable into the Primary Active I get access to the stack. If I connect to any of the other 2 switches in the stack via console I just keep seeing authorization failed.
I disconnected all the switches from the stack (it's a lab environment) and was then able to access each switch via console. The issue with Authorization Failed only seems to be apparent when they are stacked. I have another stack of 3850s which allows me access to the CLI from any of the stack members.

Anyone came across this slight issue?

Hi,

Try these commands:

Switch(config)# redundancy
Switch(config-red)# main-cpu
Switch(config-r-mc)# standby console enable
Switch(config-r-mc)#

You need Cisco IOS XE 3.2SE or later.
