<![CDATA[MikroTik CRS forwarding database]]>Hi,
I have been trying to work out why my NetXMS install is not giving me a Layer 2 map.  It is only a small test network with a Mikrotik CRS in the centre (sat between a Mikrotik router and a couple of Mikrotik access points).  I think I have narrowed it down to NetXMS being unable to retrieve the forwarding database from the switch.  Does anyone else have a similar experience and/or what can I do to get these values so NetXMS can retrieve it.
Many thanks.

Thanks for the reply (and the excellent videos that got me going with NetXMS).  I think you are spot on.  I added a bridge and it now responds but only with info from the bridge, not from the switch.

Not to worry, just another CRS thing that would have been nice.

Thanks.

Neither OID responds on that device (.1.3.6.1.2.1.17.4.3.1 responds on another MikroTik device though).  I will ask the question on the MikroTik forum instead.
Thanks for helping.

Best regards,

I can see the FDB in the GUI and another device (although a different model) does show it in NetXMS running the same version of RouterOS.

does your switch provide FDB information via SNMP?

Best regards,
Victor
