Nexus 9K support in RANCiD 3.7

Dec 29, 2017, 10:09 AM

Post #1 of 6 (833 views)

We recently outfitted a new office with Cisco Nexus 9000s. I monitor router and switch configuration changes enterprise-wide with custom built RPM packages of RANCiD on RHEL7 with git and gitweb.

The 9Ks have a constantly changing file date on a subfolder that can't be controlled:

- !Flash: logflash: 69632 Dec 29 01:37:09 2017 debug_logs/
+ !Flash: logflash: 69632 Dec 29 02:42:52 2017 debug_logs/

The following code patch to v7 prevents this from generating hourly commits and emails.

--- nxos.pm.in.orig 2017-12-29 13:02:01.347259970 -0500
+++ nxos.pm.in 2017-12-29 13:03:39.336922201 -0500
@@ -497,7 +497,7 @@ sub DirSlotN {
/\s+vtp_debug(_old)?\.log$/ && next;

- if (/ log\/$/) {
+ if (/[_ ]logs?\/$/) {
# change
# 8192 Jan 08 14:05:05 2015 log/
# to

There's also a problem with a constantly fluctuating memory size value, but I haven't figured out how to fix that.

Thank you Heasley and co-conspirators for a great tool!

I like this fix. I had a similar problem on NXOS based FC switches but opted to have it just not list out the logflash.

I like your patch better! You might want to normalize the style in the previous line while you're in there - "&& next" instead of "next if". I'm not a perl guru, though.

It is not the same as the other lines. this code block filters the size
and timestamp, but leaves the name. I suppose all of those filters could
be changed to this type of filter. open to opinion.

I have been suffering this for a long time, and since it came up, I decided
to use it.
To expand it, I have 2960 cisco switches which produce similar unneeded
output:

May you fix that?
