Revert Timer will not complete, and leaves a configuration lock

[mark.assad]

Hi, 

  I'm trying to use the 

configure terminal revert timer 1

to remotely modify configure and give me a backdoor if I get it wrong. But I am seeing that when the timer fires, the configuration isn't restoring, and the configuration is then locked, and I can't change anything anymore.

I have archive set as follows:

archive
 path flash1:archive/config

I see this when I try and make a change

switch-3-test#configure terminal revert timer 1
Enter configuration commands, one per line.  End with CNTL/Z.
switch-3-test(config)#hos
switch-3-test(config)#hostname
Mar 23 06:37:22.465: %ARCHIVE_DIFF-5-ROLLBK_CNFMD_CHG_BACKUP: Backing up current running config to flash1:archive/configMar-23-06-37-20.267-2

Mar 23 06:37:22.474: %ARCHIVE_DIFF-5-ROLLBK_CNFMD_CHG_WARNING_ABSTIMER: System will rollback to config flash1:archive/configMar-23-06-37-20.267-2 in one minute. Enter "configure confirm" if you wish to keep what you've configuredman-switch-2
switch-2(config)#exit
switch-2#
Mar 23 06:37:31.986: %SYS-5-CONFIG_I: Configured from console by vty0 (172.16.101.51)
switch-2#
switch-2#show configuration lock

Then after a minute I see:

Mar 23 06:38:22.469: %ARCHIVE_DIFF-5-ROLLBK_CNFMD_CHG_ROLLBACK_START: Start rolling to: flash1:archive/configMar-23-06-37-20.267-2
Mar 23 06:38:22.486: Rollback:Acquired Configuration lock.

But the configuration doesn't rollback. 

If I try and edit the configuration later I see:

Configuration mode locked exclusively by user 'unknown' process '13' from terminal '0'. Please try later.

And I also see:

switch-2#show configuration lock

Lock active time (in Sec)        : 1351
Lock Expiration timer (in Sec)   : 4293524

Which leaves me unable to change anything without a reload. 

Version is:

Any thoughts on what I might be doing wrong?

Thanks,

Mark

Did you find a solution to this ? I have the exact same issue

[Georg Pauwen]

Hello,

what if you globally configure:

no configuration mode exclusive auto

and then

configuration mode exclusive manual

[oracle_sod]

I cant even get into configuration mode to run this.

I have this enabled:

archive

path flash:/archive/

maximum 1

!

configure terminal revert timer 1

creates the backup

switch(config)#int gi1/0/1            
switch(config-if)#des 1111

I wait 60 seconds, nothing happens....

exit config mode and run 

switch#show configuration lock

try to go back into config mode:

gives:

Hello,

what if you reboot the switch, can you get into configuration mode then ?

[oracle_sod]

Yes, a reboot will release it

[Georg Pauwen]

Hello,

I guess what I am after is if after the reboot, you actually can configure what I suggested before...?

no configuration mode exclusive auto

and then

configuration mode exclusive manual

[oracle_sod]

Yes i can, however it doesn't have any impact on trying to have the revert timer work either on a hard second timer or idle timeout.

[paul driver]

Hello

When you inicated archive did you create an inital archive for rollback to succeed?

conf t
archive
path xxxx
end

archive config

[oracle_sod]

I didnt, however, when i run

configure terminal revert timer 1

the switch creates one before allowing further commands.
