[Observium] SVI - Vlan IF graphs

[Marco Spicuglia]

Hello there,

I would like to monitor SVI bandwidth on those devices that support such counters.
I activated the etherlike mib option in the config and started polling a Nexus 6k, which supports snmp counters on vlan interfaces.
I see the snmp counters increasing on the switch, but I see only blank graphs on vlan interfaces, which are properly detected, including their status.

The device is properly polled for anything else and it seems that all needed mibs are already included in your distribution.
I am running the latest stable release.

Any idea? Am I missing anything?

Thanks for your help.

Regards,

Marco

Hi Adam,

mmh, thanks.

--------------
snmpwalk -v 2c -c COMMUNITY HOST 1.3.6.1.4.1.9.9.648
iso.3.6.1.4.1.9.9.648 = No Such Object available on this agent at this OID
--------------

where 1.3.6.1.4.1.9.9.648 id is suppose to poll CISCO-VIRTUAL-INTERFACE-MIB, which is included in the Observium database and supposedly supported by the Nexus 6001.

Is this a Cisco bug or should I activate something somehow somewhere?

Cheers,
Marco

Are you actually snmpgetting the counters to check?

I suspect, as usual, a Cisco SNMP bug.

There really is no scope for us to fail to put interface data into the rrd.

Can't say about Nexus, but classic IOS have SVI counters in IF-MIB iirc.

You need to open TAC case about that SNMP counter issue.

Hi Nikolay,

Nexus supports the IF-MIB too, but I am getting 0 from all SVI counters, while the physical IFs have no issues, including aggregated port channels. I think I will have to open a TAC indeed.
What classic IOS devices are you using for SVI polling?

Cheers,
Marco

SVI graphing has worked for me on almost all IOS/IOS-XE platforms since
about 2001.

It didn't work in 12.0, I recall preferring 12.2S on 7200 for that
reason. :)

[Marco Spicuglia]

Hi Adam,

Thanks. 12.2 is indeed the only platform I see the SVI counters working so far.
However, the 12.2 on the 3750, where the SVI are also being graphed, does not count unicast traffic, only multicast and broadcast, which makes my measurement useless of course.
On the 7600 it seems to work fine instead. Nexus 1k, 5k, 6k and 9k is a no go so far. Busy with a TAC still.
Will keep you posted.

Cheers,
Marco

It's well known to us that half of NXOS's SNMP is broken. :)
