how to see Port Speed on switches?

thanks for the reply, it would be very nice to add this in a feature release :-)

Has any progress been made to allow this? Don't see a reason to allow us to see port speed etc during creation but not after creation. Would rather not create/cancel sensor creation, SSH or log into the switch UI to grab a high level view of port settings.

Would definitely be useful if we're able to see this information. Possibly a sensor that can detect speed/duplex changes would be nice as well.

Thanks, Sonny

I strongly agree. Being able to instantly know the port speed value is important.

We definitely have a need for this. We have a port channel where one of two ports degraded from 1gb to 100mb, and we would like to know immediately. Most likely a layer 1 cable was bumped. Are there plans for this and if so when. This item is pretty old with no real answer to the OP question.

Hi,

In the device settings, you can add [ifspeed] to the port name template (under SNMP Compatibility Options) to get the estimated current bandwidth of the port in the sensor name.

Best,
Stephan

+1 to be able to create alerts based off the connected port speed. Have some access points with cabling issues that drop occasionally from 1Gbps to 100Mbps, and it would be great if I could get notified when/if that happens.

In order to monitor changes in the port speed of an appliance, you can use the SNMP Custom Table Sensor. When creating, use the OID 1.3.6.1.2.1.31.1.1. You will see all interfaces after the metascan.

Configure as below:

This will create one sensor per interface, reading the current speed (100=100 Mbit, 1000=1Gbit, etc.). You can then configure limits on these channels, preferably via Multi-Edit on those to make sure they're only running on the speed you want them to :)

Thanks for posting this. It certainly isn't needed on each and every interface, but great to be able to do it where critical or where we have been having problems.

You're welcome! :)

It's funny when I went to add a switch sensor with "SNMP Traffic" I could see that an uplink between a few Gigabit switches was 100 Mbps not Gigabit, Is there a way to create a sensor to monitor and alert on this or make it a warning state? That's got to be some bad cabling between those switches

You could modify the Port Name Template under Settings | SNMP Compatibility Options. Simply include [ifspeed] and the sensor will be renamed according to his current interface speed. If you require to actively alert on certain (or all) interfaces of a critical appliance, check out this post :)
