"Unrouted" VLANs on Cisco

[hcpr]

Has anyone successfully graphed traffic on VLANs that are just plain layer 2 vlans (ie. without any router interfaces)?

When I try to graph this I get the following in the logs:

05/04/2005 05:55:03 PM - SYSTEM STATS: Time: 2.1361 s, Method: cmd.php, Processes: 1, Threads: N/A, Hosts: 6, Hosts/Process: 6

This is with cacti 0.8.6d
and net-snmp 5.2.1
and php 4.3.11

The Cisco switch is a 6509 with IOS 12.1(22)E1

Any suggestions?

Thanks

That tells me that the Cisco device is not giving you any SNMP data for those interfaces. I would have to direct you to Cisco for answers on how to get it to give you that data.

Cacti snmp values from a 4006 running 12.2.20 EWA

135	1	unrouted VLAN 20	VLAN-20		53	0	HEX-00:00:09:43:2F:C8:13

As you can see from the Cacti device properties, the unrouted vlans have no bandwitdh values. What info are you trying to glean from the vlans that are not bound to layer 3? spanning tree info? bpdu counts? It would be very interesting to graph spanning tree, especially on a dual core network. I'll poke around & see what I can dig up.

I realize that the 65xx & 4000s are different switches, but most of the snmp values do carry over.
