How to find when a port was last used

Micheal_Beeler — Tue, 08 Dec 2015 08:12:00 GMT

Campus switch see lots of changes and need to find a way to show ports that have not been used in a set period of time.

Look under capacity planning in inventory manager

When no NetSight is avaible and you are also looking for an great NMS YOU can do this with NeDi: http://www.nedi.ch https://youtu.be/JLU4RwUnjQA Cheers, Jan

If one were to browse the Mibs or snmp walk directly. Gathering sysuptime for the device, then ifLastChange will tell the last time the port state changed, and if IfOperStatus is down, then the port is not currently in use.
So a sysuptime of 30 days and a iflastchange of 20 days means the state changed 10 days ago.
If a sysuptime is 0. The port was typically never operational since last boot.
This is the hard way to do it.

It's not what you are really looking for, however an indirectly possibility would be to compare Link Status and "Bytes Transferred" in Capacity Planing Report. If zero bytes were transmitted on a port, probably this one was never up since the switch is running.

Is this person's assumption correct? I have a switch that has been up for 200 days, I need to know if the ports were active in the last 6 months at least. Thanks!

It compares backups, so the dates are the oldest and newest backup.

I try to only use the ports that show no "Bytes Transferred"

Another option is to check via CLI.

show port info detail | include Port:|Link\sState:|Link\sUps:|Link\sDowns: will get you a pretty concise list of all ports with their current state as well as the time of the last link up and link down. See the example output below from one of my lab switches.

X440G2-12t-10G4.1 # show port info detail | inc Port:|Link\sState:|Link\sUps:|Link\sDowns: Port: 1
Link State: Active, 1Gbps, full-duplex
Link Ups: 1 Last: Thu Aug 03 16:59:29 2017
Link Downs: 0 Last: --
Port: 2
Link State: Ready
Link Ups: 0 Last: --
Link Downs: 0 Last: --

I'm running on a stacked c5. Is there an equivalent to this command in that OS?

BrandonC — Tue, 08 Dec 2015 22:15:00 GMT

As far as I know, there isn't an equivalent on the C5. However, I'm much more familiar with EXOS that with the C5, so maybe someone with better knowledge of the C5 will be able to show us a way to pull this info out of the CLI.

I spoke to someone who indicated this was a good report to determine unused ports as long as capacity planning was part of the archive process.

I need to verify that it is an accurate report and understand how a singe device can have too different dates in the date field.

According to "Help" Date = The date and time of the data sample used to generate the port information.

Thanks,

If you have a syslog server you could also query via a filter to switch ip switch port and get all the port for up down entries within your date range. Depending on how many ports are inactive as how many times you would need to repeat the query changing the port filter.

Hi,

I know, this is an old thread, but I have to count a lot of active ports right now, because old B5 Switchs need to be replaced soon! I found the Port Status VLAN Flex-View very useful for this purpose. Especially with the XMCs capability to export the flex view to a csv and some Excel-filtering, its fairly easy to get this information!

Just wanted to share,

Robert
