Major Description
Hello,
We detected 2 issue regarding the fdb table for ios-xe devices.
First one, the mac-address showed in the web-interface for 1 port it has the same entry repeated many times (see picture attached).
The second issue is related to the way observium collects the fdb table, it only does for vlan 1 and vlan 10 but not for the rest of vlans created on the switch (we are doing the polling in v2c), attached the output for ./poller.php -d -r -m fdb-table -h cisco-iosxe-1706 and the picture as example of vlans present in the switch.
Thanks.
EM

Hi Mike,
Sorry for late response.
In new version (r13024) now I can see it request for each vlan registered on the switch:

Any version before r13024 only do this:

You can consider the problem fixed.
Only a small question, if you have any idea how I can fix the same mac-address that appears in same port multiple times? (image observium-fdb-table1.png)
Thanks,
Greetings.

Not sure, if this relevant to your trouble.
But in r13024 was fixed issue with detect vlan context when 1th vlan return empty data.
Try it - need device rediscovery (for check vlans) and later poll fdb-table.
I can't reproduce this trouble with other Cisco IOS-XE devices.
I sure, trouble on your local poller (not know which).
If you can, provide me access to your observium install. If that possible, write me in Discord (user landy). Link to Discord channel in firs comment from Bot.

Yah, ok. Not know reason, but in r13031 added remove duplicate entries.
