Hello,
I have a rather funky problem with a few switches when adding them to NAV. Some of these swithes are *OLD* 2500 and 3500 series, and NAV will simply fail getting the serial info from the switches. Instead it will poll something like "0x0000F". I've been thinking for a long time that the serial OID was unsupported by the certain old IOS, but recently I've started seeing the same behavior on newer Cisco series such as the Catalyst 3560 series. NAV will fetch the serial info off some of these devices just perfect, while with some switches will return "Cisco 3560" as serial. I've tried added a fake serial on the few switches where I have this problem, but NAV often fails in general to poll port info etc off these devices with bogus serial info.
I've done some research on two EXACT same devices (series, IOS and bootstrap version) and here is the info:
Both devices show:
Cisco IOS Software, C3560 Software (C3560-IPBASEK9-M), Version 12.2(46)SE, RELEASE SOFTWARE (fc2) Copyright (c) 1986-2008 by Cisco Systems, Inc. Compiled Thu 21-Aug-08 15:26 by nachen Image text-base: 0x00003000, data-base: 0x01600000
ROM: Bootstrap program is C3560 boot loader BOOTLDR: C3560 Boot Loader (C3560-HBOOT-M) Version 12.2(25r)SEC, RELEASE SOFTWARE (fc4)
SOME-HOSTNAME-SW uptime is 1 day, 10 hours, 48 minutes System returned to ROM by power-on System image file is "flash:c3560-ipbasek9-mz.122-46.SE.bin"
... and they both show their serial info in "show version" or "show hardware".
I can understand how it COULD fail on some devices for SOME reason, but why would it completely halt NAV from polling info properly? And can someone please report back if they have the same problem? (maybe it’s a bug worth troubleshooting?)
Have a very nice weekend everyone, and good luck with updating! (and maybe I see some of you in Barcelona next week) :)
