supress diffs for certain config parts (port security CatOS)

Post #1 of 3 (1086 views)

Now that rancid is running smooth (thanks to Anchi and John) I would like
rancid to not doing diffs for certain parts of the config? Why? I'm running
port security with dynamic update on the C6509 CatOS boxes and the MAC
addresses hence are part of the config. As these are changing frequently
rancid sends config diffs almost always.

Is there a knob to turn off diff for certain parts? Or more precisely: where
do I have to insert a "grep -v"? Perhaps this could be made a feature. I.e
specify a file with regexp pattern which will be omitted when doing the
diff?

Hi Arnold - if this fits in with your environment (i.e., the person
complaining of the constant diffage uses procmail) you could use a
procmail filter, as suggested by John in the archives. See:

http://www.shrubbery.net/pipermail/rancid-discuss/2002-September/000253.html

and search for "almost all bgp speakers" in that (that text is at the
end of the relevant post). This doesn't stop the diffage, but you'll
only get email about diffage that you care about.

cheers

fwiw, It is a goal to add more configurability, likely in/to become 3.0.
