I have a Cisco 4500 switche connected to a Service Provider router with a GigabitEthernet L3 interface and I am running EIGRP with the SP router.
I enabled IP accounting output-packet on my switch interface but it is not collection any traffic statistics.
Do you know what can cause this? Maybe all the traffic is being switched instead of passing through the RP?
CEF based multi layer switching can be the answer.
also when enabling ip accounting on a SW based router I see in some newer IOS version a warning message that says that packets processed by MLS will not be accounted.
Depending on your supervisor model and IOS image you can use netflow for accounting.
>> To use the NetFlow feature, you must have the Supervisor Engine V-10GE (the functionality is embedded in the supervisor engine), or the NetFlow Services Card (WS-F4531) and either a Supervisor Engine IV or a Supervisor Engine V.
you can then export data to a a netflow collector server that allows nice aggregations of traffic data.
However, some sup models for C4500 don't support it including the newer 6-E.
Hope to help
