Hi There,

I like seeing the Average Packet Size on Ports since 4361.
But unfortunately I don't have data in graphs for all devices.

It's working on:
- 6500 VSS (Ten/Gig/Vlan/Po) (IOS 15.0)
- ASA 55xx
- Servers (Linux)
- Riverbeds (Linux)
- Cisco-WLAN-Controllers

It's NOT working (empty graph) on:
- 4500 (Ten/Gig/Po)
- ASR1001 (Gig/Tu) (IOS 15.3S)
- 7301 (Gig/Tu) (IOS 15.1M)
- 28xx (Gig/Tu) (IOS 15.0M)
- 18xx (Fa/Tu) (IOS 12.4T)

Especially on our VPN-Rouers (73/28/ASR) this would be helpful.

How can I debug some more things to get it working?
Or how can I support you with information that you get it to work?

The graph relies on if[In|Uut][U|NU]castPkts existing on the host. If they're not populated, it won't work.

There isn't really a fix if the devices don't expose those counters.

Hi Adam,

I think it's not a good idea to use the NUcastPkts Counters.

in 32bit-counters the NUcast counters are deprecated - see IF-MIB:

ifInNUcastPkts OBJECT-TYPE

SYNTAX Counter32

MAX-ACCESS read-only

STATUS deprecated

DESCRIPTION

"The number of packets, delivered by this sub-layer to a

higher (sub-)layer, which were addressed to a multicast or

broadcast address at this sub-layer.

Discontinuities in the value of this counter can occur at

re-initialization of the management system, and at other

times as indicated by the value of

ifCounterDiscontinuityTime.

This object is deprecated in favour of ifInMulticastPkts and

ifInBroadcastPkts."

::= { ifEntry 12 }

and there aren't any NUcastPkts-Counters in the 64bit-section (HC-counters).
And as you know its really not a good idea to poll 32bit counters on ports over 100Mbit/s.

and yes - our 6500 has NUcastPkts-Counters.... and they are 32-bits... on 10Gig/s-Links...... however....

So I think moving from NUcastPkts to [Multicast|Broadcast]Pkts could be a good idea.

i did some walks on an cisco-1812:
