Solved: Configuration Register Mistake

ahmedsalahomar · ‎10-16-2008

I have a Cisco Routers LAP

one of my trained students puts by mistake on a router Configuration Register 0x1242

I can not now loggin in Router by console ( unfortunately no other ports configured to access )

what can we do to take it back ?

Hello Ahmed,

the new settings has changed the console speed.

If you can access via telnet the LAP open a session and change it back to 0x2102

conf t

config-register 0x2102

otherwise via console try with:

1200 bps

2400 bps

4800 bps

115000 bps

one of these should be the new speed

Hope to help
