Hi all

Just following on from the ARC tftp upload thread, does anyone have an cunning way to backup and restore the full config of an NMC or ARC card.

Not to be an ass, but since I never found a way, I initially ran a script of my first config and saved it out as a file. Whenever I make any changes, I also make it to this file. So far, it's made configuring new ARCs extremely easy...

I do this too, but, it gets way out of sync with reality very quickly as soon as you log into the ARC and start tweaking things to work around problems.

Now of course a single config file like a Cisco has would be wonderful, as it makes it super easy to back things up. Long ago I tftp'd down all the files I could grab off the thing and really couldn't find a single file with all settings...

There is one, but it's binary. Look up "bulk configuration" in the docs, or use HARM to do it. There's no way that I know of to dump the config out in text like a Cisco does. Someone hinted a while ago that 3Com had such a tool internally... but I never got anyone to confirm the existence of something like that. Since I can't find one, I'm going to write one if nobody else fesses up and saves me the work. I've already started, but it's slow going, because I'm still trying to come up with an elegant data structure for mapping the command names to the SNMP OIDs that store the values without hardcoding every stupid verb into the program...

Do you really need to convert it back to CLI format? Can you store it in a way that your tool could restore the config back automatically, or copy it over to another automatically? Personally, I think that would be even better than a CLI config tool...an SNMP config tool. Say...here's a template that I want all of my ports configured like...and let it go in and do all of them that way. Something like that would be even better IMHO. Still have to come up with a data structure to store that, but that should be rather more easy to do than a conversion to CLI commands.

Well, it doesn't HAVE to be in CLI format, it'd just be nice. :) Just dumping a config in *any* kind of text format so you could at least diff it against another config would be handy. And that much I could do with just a bunch of snmpwalk commands. Sounds like you're talking about making it work like my 'checkusrcfg.pl' script does, which configures everything in the box except for the ARC. I could probably just throw ARC config data into that, using the SNMP proxying thing, though of course that'd be a lot slower than just doing it directly. That doesn't deal with tables all that well, and the code's already pretty ugly. :) Mike Andrews (MA12) * mandrews@dcr.net * http://www.bit0.com/ VP, sysadmin, & network guy, Digital Crescent Inc, Frankfort KY Internet services for Frankfort, Lawrenceburg, Owenton, Shelbyville "Don't sweat the petty things, and don't pet the sweaty things." - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
