Keep in mind you can always copy a config script into running config, that will allow you to remotely unconfigure an interface and configure it without risk of your CLI session being broken and the re-config part not being applied. So schedule your reload, copy your (hopefully tested) script into run. If you can get into the device remotely still (and then verify your config change worked), you can then cancel the reload. Else wait 5 minutes and try again.

It will probably be disruptive, but IIRC, the subrate DS3s just used the 'dsu bandwidth' command? That gives you a chance to just type the command on the remote, and then on the local and wait for it to sync up again. One trick you can do, is to schedule a reload up for say 5 minutes, do your config, see if it works, and then cancel the reload and 'write mem'. Not quite as neat as "commit confirm" on JunOS, but still gives you a safty net. Now, if you needed to mess around with subrate T1, you would definately need onsite hands on, to unconfigure the t1 groups, and then reconfigure the t1 groups. But the DS3 was just the single command from what I remember. _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
