Hi,

I tried to enter the configuration mode of my cisco 4507 Yesterday and received an error when I tried to make a change. I received the following error:

"Config mode locked out until standby initializes

configuration mode locked. Please try later."

I have pulled the show module command as below:


Chassis Type : WS-C4507R

----+-------------------+-------------------+----------------------------------
 1   Active Supervisor   SSO                 Active
 2   Standby Supervisor  SSO                 Standby cold



I cannot console in to Supervisor 2. This is Critical hardware and I cannot reboot the device. Does anyone have any suggestions as to what I can do? Can I pull out Supervisor 2 and plug it back in without causing a service interruption? If not, what can I do to bring back configuration capability to the running supervisor?

The sup in slot 2 has failed (or has a fault, or has crashed, etc.).  You can remove it and reinsert it. Since the sup in slot 1 is active, this won't cause a problem.

The reason the config is locked is that the active supervisor cannot synchronize the config with the standby supervisor (which is up but not communicating). Either reload the standby supervisor (reload module 2) or remove and re-insert the standby supervisor.

is there a way to reload the module from the command line? or do I have to physically remove the card and reinstert?

What are the risks of doing either of those? This is a very critical piece of equipment to our Company's carrier services and it cannot go down. However, I have to make configuration changes in it soon and need to be able to configure it.

If there is risk to rebooting the card, is there another way I can unlock the config mode?

reload mod 2

What are the risks of doing either of those?
None, really. The active supervisor is doing all the work.

If there is risk to rebooting the card, is there another way I can unlock the config mode?
No and no.

If you're nervous about doing this (and that's a good thing), wait for a maintenance window. Or if you can't one, wait until a slow time (early morning or weekends). Assuming you're not a 24x7 shop.

Wish there was a way to filter users.  This one rarely gives an A. I can't believe they got that many answers which weren't complete.
