I have a 9124 in and HP Blade server and I goofed up when setting up tacacs without first defining roles. Now of course there is only the fault role on the switch:

role name default-role

description This is a system defined role and applies to all users

rule 1 permit show feature system

rule 2 permit show feature snmp

rule 3 permit show feature module

rule 4 permit show feature hardware

rule 5 permit show feature environment

but I have admin setup:

username admin password 5 <snip> role network-admin

but no role defined for network-admin. So I killed all exec access. How do I fix this?

I did try to send a break when booting to restore config that way but that is not working, only can assume that something about it not having a physical console port is causing an issue.
