Sure, this topic is something of an FAQ.


* Edit the rancid executable (or whatever executable you happen to be using to collect the data)

* Most of the stuff for normal commands will be in the 'WriteTerm' callback (see CommandTable)

* There should already be an ntp clock-period match in there somewhere. In mine, it looks like this:

# Dog gone Cool matches to process the rest of the config

/^tftp-server flash / && next; # kill any tftp remains

/^ntp clock-period / && next; # kill ntp clock-period

/^ length / && next; # kill length on serial lines

/^ width / && next; # kill width on serial lines

* Next find the ShowEnv subroutine

o Look for 'next if' in the while (<INPUT>) loop. Add a line above or below that says: next if (/INTAKE/)

* Similarly for ShowFlash subroutine, add a next if (/bootflash/) if you don't want to see bootflash.



'next if' is the generic answer about how to eliminate things. Look in @commandtable to find the command that gets executed, that maps to a callback. Go to the callback and add a 'next if'.

Subject: [rancid] Excluding config lines in Rancid

Rancid is detecting configuration changes on a few configuration items in Cisco switch configurations that are automatically updated and Rancid should exclude from it's comparisons.

On a Cisco Catalyst 3560 switch running software version 12.2(25)SEE4 Rancid is reporting changes to the "ntp clock-period" command:

- ntp clock-period 36029104
+ ntp clock-period 3602910

On a Cisco Nexus 3548 switch running software version 6.0(2)A1(1e) Rancid is reporting changes to the following configuration items:

!Env: INTAKE 45 29
+ !Env: INTAKE 45 28

- !Flash: bootflash: 5356844 Apr 22 17:42:48 2014 BufferMonitor-1HourData
+ !Flash: bootflash: 5356844 Apr 22 20:42:48 2014 BufferMonitor-1HourData

Can Rancid be configured to ignore changes in these lines?

I am currently running Rancid 3.0, but had the same issue in 2.3.6 and 2.3.8.

Thanks.

this be filtered by stock rancid 3.0. i can not imagine why it would be
missed until the device were not configured as 'cisco'.

Thanks. The problem with the 3560 was that is was set to cisco-nx instead
of cisco. Once I corrected this the ntp clock-period discrepancy no
longer appeared.

On the Nexus 3548 switch the "BufferMonitor-1HourData" no longer seems to
appear after your changes, but the INTAKE config line still does:

- !Env: INTAKE 45 29
+ !Env: INTAKE 45 28

Here is a snipet from nxrancid with your change for excluding INTAKE:

s/ +$//; # Drop trailing ' '
next if (/Fan Zone Speed:/);
next if (/INTAKE/);
ProcessHistory("COMMENTS","","","!Env: $_");


Thanks again.

Correct, you need to escape quote the center slash in 'AI/ML' with a
backslash as it is also used as the delimiter for the regex. Try this

next if (/AV AI\/ML Model:/);

I have this problem also,, but don’t know where to make the update.

Thanks…

Hi Rancid Users,

Thank you Andreas! that did the trick,

Tim I am running rancid 3.13, I did edit # fortigate.pm - Fortigate
rancid procedures

under:

if ($filter_osc >= 2) {
...
...
...
...
...
...
next if (/^\s*Virus-DB: .*/);
next if (/AV AI\/ML Model: .*/);


Regards

Juan
