[rancid] Issue with Brocade FC capture and line length

[Erik Soosalu]

Yeah, I agree that 11K is ridiculous for a single line.

brocadelogin -c "configshow -all" <host> did not work.  The line is altered only showing the last part of the line.

However, that info gave me enough to go on.  brocadelogin is an expect script, and expect does have a default bufferlength and it is a rolling buffer (from what google told me).  I added in max_match 60000 in the run_commands section and now I get the full line.

Thanks for the help.
Erik

When I look at a normal configuration upload, this line is 11,000 characters long.  If I ssh into the switch and show the config, I see 11,000 characters.  However, when I look at what is captured by RANCID, I only get a line that is ~4200 characters long, and it appears to be the last 4200 characters of the line (like data is rolling through a buffer).  I can't seem to find anywhere that is setting this length.

11k is ridiculous.  did they hire folks from Foundry.

is it really whatever you are using to view the file?

does brocadelogin -c 'whateverthecommandsistodisplaytheconfig' hostname
work?  else it might be perl, though a search suggests not; brocaderancid
hostname and look for the truncation.  is it the SCM you're using?
