I have a 4506 and WS-X4548-GB-RJ45 module on it. I have www server in vlan A, Sql server in vlan B. WWW access needs to access sql.
Currently the issue is, when I sniffer on one WWW server, sometimes I can see the traffic between other www servers to their related sql servers besides the traffic between this www server and its communicating sql. Sometiems it's normal.
Any one knows the reason? maybe the module?
