Hi,

An autodiscovery on nexus 5596UP (width L3 module) doesn't show VLAN interfaces. It works on cat4503.

interfaces nexus vlan

When you add a SNMP traffic sensor to the device normally, are you able to see the VLAN interfaces then?

Have you tried scanning the device's interfaces with the SNMP Tester to see if they show up?

Hi,

I'm evaluating PRTG. Looks very nice. We have nexus5k en UCS since last month. If I choose add sensor/snmp library/Cisco-interfaces.oidlib => I get a long, long list like this: IF-MIB if: 16842752 if index.

Colom 'Names' is different for each if: if type, if index, if mtu, ...

Is if = 151060520 correct? Which 'Name' do I have to choose? We want, UP/down status, traffic,...

Thanks. Johan

It's hard for me to say exactly with this output which interface you want to monitor and whether that is the correct interface but in PRTG when you use the Cisco OID template, you should see other lines in the OID for things like if oper status which shows the Interface Operational Status and if speed for the traffic. If you select those for the interface you want, it will create the graph and data table accordingly.

With regard to the SNMP tester output, the port BRUSWISUP11 - Inband Mgmt relates to the alias 151060481 and that is what should be listed when creating the Library sensor.

Hi, I've tried this morning with the following sensor 'SNMP traffic 32bit sensor' (same as on the catalust 4503 with IOS) but the counters stay at zero. It looks like that Cisco does not add anymore counter to their VLAN Interfaces. any idea where they store the counters for those virtual interfaces?

best regards Johan

Looking through the OID tree here, it looks like it may not be possible to track the traffic through SNMP for VLAN interfaces:

Hi, I think there is a way to monitor the traffic.

I found a command to display in the CLI the counters (snmp)

show interface vl1 counters snmp
