MAC address & ARP table can both read the ASR 920 but not FDB table the ASR920 ain’t showing up under FDB-table.
It’s probably an easy thing to solved (at least i hope so), we got a bunch of ASR920 in our network.
Still haven’t seen any FDB support for Cisco ASR-920.
Cisco IOS XE Software, Version 16.06.05a
So i’ll bump this request!
Best regards

Please open an issue on github for new device support (https://github.com/librenms/librenms/issues) or have a look at the documentation to add the support yourself :
https://docs.librenms.org/Developing/Support-New-OS/
I can have a look at the issue, and we’ll see if the mac address table is available on those devices.
Bye
Nice, I’ll open a issue on github.
The ASR920 is supported in Librenms (ARP table works and so on) but just not the FDB part, so I guess t shouldn’t be that hard to add.
The FDB table is standard. So I am afraid that the ASR920 does not provide this capacity. Which makes sense because FDB table is essentially found on switches, not on routers. Routers have an ARP table, which you confirm you get in LibreNMS.
But the issue data will confirm or infirm this.
Yeah, could be that they don’t use standard FDB table in them.
The ASR920 is a router with L2 capabilities and we are using over 500 of em as pure L2 switches.
So i guess you should be able to get the info somehow but not the standard way. 
Ok, you can close this request.
Got some answers from Cisco now and ASR920 ain’t supporting BRIDGE-MIB.
Might come a function through YANG but we’ll see…
Thanks anyway!
