All,
I've started adding the ability to link between files (e.g. BGP
neighbor statements, assuming you have both configuration files)
I'd be very interested to hear anyone's feedback if they've gotten the
script to work or have some ideas for improvements like Robert suggested
Thanks,
-Jesse

All,
(This is me scratching an itch of my own and hoping that it might
be useful to others on this list. Apologies if it isn't)
When trying to comprehend a new or complicated Cisco router
configuration an old pet-peeve of mine is how needlessly difficult it
is to search for a list referenced by a command, figure out what it
does, then find my way back to the original command (by which time
I’ve forgotten the details of the list) and figure out what it's doing
with that list.
So I’ve been working on a small perl script to add links within IOS
configuration files, e.g. link to an access-list from the interface
where it’s applied, making it easier to to follow the chain of logic
with stuff like route maps or nested service policies via clicking
links and using the forward and back buttons in your browser to go
back and forth between command and referenced list.
I know there is a lot of stuff I could add in to this (e.g. more
VRF-related commands, PIX/ASA, Juniper etc). Let me know if you think
of anything new or notice something I’ve done wrong , there's plenty
of room for improvement and expansion to other configuration formats.
Notes:
Anything referenced (or potentially referenced) by something else
is in bold. It makes it very easy to see where ACLs etc. start and end
There's also an option in there to reformat some numbers that are
hard to read (e.g. traffic shaping criteria) into more human-readable
ones. Pure fluff.
Surely this has been done before but I couldn't find anything in a
few brief moments of searching so here we are.
Files are here: https://github.com/jlmcgraw/networkUtilities
At the very least you'll need iosToHtml.pl, pointers.pl, pointees.pl,
and human_readable.pl and several CPAN modules (see setup.sh for easy
ways to install them under Debian-derived Linux. I haven't tested this
at all under Windows or OS X)
