Checking Bandwidth Usage

[ccannon88567]

I have a LAN extention network (All l2 arpa encap) with L3 switches on each of the sites. Users are complaining of slow speeds.

I have ruled out misconfigs, interface errors, Processor Peaking, Log anomoies, Loops and routing instability, acl etc.

The only thing I can think of is that the delay could be is the 10Mbps LES circuits are not enough. How do I measure if the bandwidth is being maxed on the uplinks at the busy points of the day?

Do I need to run some IP Traffic analysis software such as cisco netflow or can I determine if we need more bandwidth from local switch commands?

Please advise!

With the benefits of packet switching in ASIC

Bingo, hence those switches need NetFlow in ASIC to maintain the speed. This component is not added in low end switches to keep the cost down.

That makes sense :-)
