[c-nsp] Cisco 3550 Vlan Interface Graphing

[William Jackson]

Hi all

 

We have a 3550 with some SVI interfaces.  We wish to graph these in
MRTG/Cacti but do not seem to be getting valid readings.

We also monitor the etherchannel uplink from that switch and this shows
traffic properly.

 

Is there a known issue with the vlan interfaces or could it be that
because the switch uses CEF switching, the vlan interface counters are
not modified accordingly?

 

Any tips would be gratefully appreciated?
