I have configure my 3750 switch for span. In this switch my IPS 4255, Internet router and Pix firewall is connected.

Below mention is the span configuration

monitor session 1 source interface Gi1/0/1 - 3

monitor session 1 destination interface Gi1/0/5

now the problem is the that IPS capturing traffic twice once while going out and once while coming in.

I wana know how to configure monitor session that it only capture traffic that is coming from Internet. Not traffic that

is originating from inside of the network.

In switch port 1 Internet router is connected, port 2 is for firewall and three is for concentrator.

I m confuse about the span port configuration either Rx or Tx. Right it is both Rx and Tx.

You can specify the direction you want to captire traffic in your "monitor session" command. The default is both Receive and Transmit. Thy this version of your command:

monitor session 1 source interface Gi1/0/1 - 3 r
