[rancid] Re: spanning tree/portcost changes causing diffs

Ah, but the problem isn't limited to CatOS.  Though the format and content is different, I see regular VLAN port state
changes acknowledged by all switches - IOS and CatOS.  CVS may not be affected for IOS, but the diff is run and reported
regardless.

Similar nag reports are noted for Flash changes.  They are usually 1 to 3 byte changes in the amount of memory reported
by IOS.  No significance found (and no understanding of why the sizes would fluctuate), but it is a diff and gets
reported nonetheless.

Looking forward to the changes.
Dave

All,

To kill this one once and for all I will answer some questions.

1.) Yes CVS will fill up because the Catalyst OS based switches save changes like these in the configuration. You don't
see this in the IOS versions because they don't save this i the configuration.
2.) I completely agree. Which is why I have written changes to cat5rancid so it will no longer see these changes. I will
share these changes .... well the simple ugly fix for these. I can not say they will work on all OSes but I know for
sure it runs just fine on Redhat 9 (yes old, but it was an old server I had) and Suse 9.3 (yes old once again, but it is
my tools server. :( ). I will post this complete change on Monday/maybe this weekend if I get time as I need to still
add the configuration option to turn it on/off. That is extremely simple but would like to test it first, before telling
people to use it.


Hopefully my simple but ugly fix will work you Dave an many more that tend to do just like most everyone ignore the
changes due to the sheer number of "set spantree port" messages. Well at least to me these are the noisy ones.
