Extreme Networks Summit Switch LAG/Bond Metrics

Help

Hi all,

First post here, as to be honest so far everything LibreNMS related has gone immensely well!

We have a pair of Extreme Networks switches that are configured in a stack, with a single bond/LACP interface used to connect to another network.

LibreNMS discovers all the ports on the device just fine, but sadly we seem to have no way to view the aggregated stats for the bond/LAG.

On our older 3Com kit when we added a LAG, we’d get an extra pseudo-port pop up to represent the combined interfaces, with each individual interface still reporting their own stats. Sadly Extreme doesn’t seem to do this, or at least LibreNMS is not picking it up.

I’ve seen on the Extreme documentation (https://gtacknowledge.extremenetworks.com/articles/Q_A/Standard-MIB-doesn-t-support-LAG-Ports-on-Extreme-Devices) that there are items in the MIB that represent this data, but they do not appear to be in the LibreNMS MIB file.

Any pointers or thoughts people can offer on this would be much appreciated!

Thanks.

Can you pastebin snmpwalk -v2c -c COMMUNITY HOSTNAME IF-MIB::ifTable ?

Hi,

Sorry for the delay on this reply.

The data requested is here:

Thanks.

This is what I found:

In EXOS, there are not counters for the LAG as a whole. You would need to monitor traffic on each member port then aggregate the statistics from that.

Perhaps, this will be useful: Interface Description Parsing - LibreNMS Docs

That’s a shame! Rather odd that they don’t expose this data directly too.

Thanks,
