[mrtg] Re: Cammer with old Catalyst 5000 - need workaround

[McDonald, Dan]

I finally got around to hacking up cammer to handle the nasty bug-ridden
5500's with ancient code....  If anyone is interested please let me know.

Subject: [mrtg] Cammer with old Catalyst 5000 - need workaround



I've been running a hacked up version of cammer for about a month.  The
other day I noticed that a mac that had been around for months was not
showing up in the table.  A little digging and I found  cisco bug
CSCdp80044, which essentially says that the sparse table array that cammer
uses was completely hosed in earlier versions of CatOS - you can poll
individual mac addresses just fine, but you can't walk the table with any
hope of real answers.  
[...]
So...  I've got a pile of 5500s running 4.5.13a.  I can't upgrade them
because they don't have enough memory, and even if I could managability
isn't a good enough reason to take them out of production by itself.  I'm
getting ready to re-write cammer to check every address from the ARP table
individually, but before I did that I wanted to check if anyone had done it
before so I don't have to re-invent the wheel.
