is possible to register the traffic vlan of switch 3560 on mrtg?

[jcasasola]

I have to register the traffic from some vlans from the swicth 3560 on mrtg. When I try to do this, my registers are no congruent.

Install Cacti and use that instead. It's smart enough to register the VLAN's OID and graph the traffic.

You probably CAN do it with MRTG, but I don't know how.

Hi.

I have running MRTG also PRTG, however I can´t register the vlan traffic. The registered data are not congruent for the catalyst 3550 and 3560.

I open a ticket with a Cisco support channel in México. This Cisco Support channel told me that is impossible to registered vlan traffic for Switches Catalyst 3550 and 3560. Is possible register this info only for Catalyst 6500 and 7500 using NMA.

Whit MRTG and PRTG I get the info about the switch port is ok, but the register data for vlan traffic has a issue, are not congruent.

Dou you know is this is possible?

Regards.

Are you talking a layer 3 VLAN interface (SVI), or the layer 2 VLAN?

You can't get traffic summaries froma  layer 2 VLAN - only from a VLAN interface - the layer 2 VLAN doesn't track traffic levels - given that you can have multiple ports IN a layer 2 VLAN it'd be extremely resource intensive for the switch to maintain a table for ALL the active interfaces at layer 2 level.

For example, on onf of my switches, I can do

show interface vlan5

and get traffic levels, including 5 minute input and output rates, total packet counts etc.

but I can't do

sh vlan5

and get the same output.

So if it's the former, you should be able tog raph it with Cacti (and maybe MRTG) - but if it's the latter, you can't - there's no tracking of total traffic at layer 2 level across the switch, only on individual ports.

I understand.

I looking for tracking the layer 2 vlan individually.
