Hi,
I had a look at several C891s we have. One didn't provide the FDB via SNMP, the others did. I don't think that's a NetXMS issue, as all four devices poll ok via SNMP. One of them simply didn't have any data in the table. Could be a firmware issue. The one that didn't work was running a 15.0 firmware, the others were all on different versions of 15.2.
Regarding the switch topology, do you have CDP and/or LLDP enabled on the router and switches?
Cheers
Thanks for the reply and checking this out for me! I'm running 15.7(3)M on my 891, so perhaps there is an SNMP issue there somewhere. "sho mac-address-table" from ios shows a good table, but when looking at the "Interfaces" tab in NetXMS shows no peer nodes or peer MACS, aside from switch. It is showing the port alias, mac addresses of the ports, etc., just nothing in Peer Node, Peer MAC, and Peer IP.
I do have CDP and LLDP running on all my Cisco devices. I've triple checked both on everything out of my determination to fix this.
Two questions, if you don't mind. Are you running NetXMS 2.2.5, and what driver does your 891's use? Mine comes up as GENERIC, although I tried CISCO-SB and got the same results.
Thanks again,
Mike
