6500=HUB!!

[aaffolter]

Hi,

I have two switches 6500 sup2/msfc2, IOS Version 12.1(22)E. Hsrp, OSPF are configured.

When I connect a sniffer on a port, I see the traffic of others clients as if the span is configured.

It is a known bug ?

You should only see broadcasts and things like that from other users if they are on the same vlan . You should not see legitimate source/destination ip traffic unless span is configured .

I would not think it as a bug to begin with. Most common reason is unicast flooding. The common reasons are discussed in the following tech tip

Thank you for your reponses, the description of unicatflooding in the tech tip resembles so that I meet on my 6500. I will take the advice of the tech tip, to try to limit these unicastflooding
