Hi.

I have a Cat 6509 with 9x48 port cards in it. Unfortunately when we do
moves/changes around the building, not everyone unpatches at the cat
when a port becomes free.

Is there anything i can use to check the last time a port was in use,
to make sure i can unplug it?

I've looked in ciscoworks and solarwinds engineers toolkit, but i can't
find anything...

Thanks

Pete.

Hmmm ... the C6509 only has 9 slots. How did you manage to put 9 48-port
cards in

Assuming that you are running CatOS (otherwise a "show interface" should do)

1. Do "clear counters x/y" ans look after the port some time later
2. Run statistics (e.g MRTG or RTG) across the switch.

No. The closest you can get is to look at the SNMP entries for
the last time the port state changed. And unfortunately on at
least some devices (including a 7204VXR) the last-changed times
appear to be more or less nonsense.

If you are sysloging port ups, you could check out your log entries for that
port. We use custom made SNMP scripts to record all that info.

if you need minimum one supervisor engine

Alt - there are some MIB interface bits which give you "time since last
state change" (or there were on the IBM hubs i did this on a decade ago).

So you need an SNMP function that can see if the port is down, and hasnt
been up for xxx days (i used 3 weeks to allow for holidays) - then the port
is effectively not in use.

note the port for re-use.

if you are really paranoid, have the script turn it off so no one can reuse
it without asking

Note - this isnt going to work if you reboot the boxes frequently, have
unreliable power etc.

interfaces.ifTable.ifEntry.ifLastChange.*

Unfortunately on at least some of Cisco's devices, the values are unusuable.

pix up 70 days 6 hours
interfaces.ifTable.ifEntry.ifLastChange.1 = Timeticks: (0) 0:00:00.00
interfaces.ifTable.ifEntry.ifLastChange.2 = Timeticks: (2189310656) 253 days, 9:25:06.56
interfaces.ifTable.ifEntry.ifLastChange.3 = Timeticks: (0) 0:00:00.00
interfaces.ifTable.ifEntry.ifLastChange.4 = Timeticks: (4052812544) 469 days, 1:48:45.44

So apparently our outside interface flapped right as I was asking
the question, and our inside interface hasn't been down for 400 days
longer than the last reboot...

The above is from a PIX, but I have seen nonsense values on a 7206VXR
as well.

Hi all.

Thanks for all your replies.

You are all correct - it only has 7 line cards, and 2 sup's

I do syslog the Cat, but I can't see an easy way to determine which
ports are in use/not - but i'll give it a go!

Thanks

Pete.

As long as you do not use converters, your side will go down, if the
other shuts down/disconnects.

Hence by looking at the state of the port and evaluating the syslog you
could generate an own table giving exact status.

Combining with incoming traffic this should give you a fairly complete
picture.
