Hello,
We have a C6509 switch. For some reason, if I enable Ether Real on my computer I am able to see some traffic from other VLANs. This defeats the normal behabvior of a switch. Can anybody shed some light on this?
Remarks:
- There is no port mirroring configured on any VLAN or switch.
Thanks,

Hello Glen,
Thanks for the link however in my situation I have only one router which is the default gateway for all the VLANs and it is the C6513.
Let me know your thoughts,

Also, the traffic I am seeing on Ether Real is not related at all to the VLAN my laptop is in. I am seeing traffic between two hosts on VLAN 203 for example.

Hello Glenn,
I am suspecting an issue in cabling. Such as somebody has connected a switch to itself!
Let me know ur thoughts,
