Hi every one....

I am using 3750 router between 2 locations with a VWIC 2MFT E1 interfcae. The traffic is going to the serial E1 to the FE0 interface then to the rest of the network. My question is there any way that I can dublicate the traffic of monitore it to the second FE interface. I want to plug a sniffer there to prove for my customer the encryption methode used.

Thanks :)

I'm not familiar that much with 3750 router but did you try on spanning the port.

Or if not available you can buy this device called NTAP. http://www.networktaps.com/assets/pdf/nTAP_B.pdf#search=%22ntap%20device%22

We use this on our MC3800 router and a couple of routers to monitor traffic if their are abnormalities in our e1. Hope this helps.

Hi Ahmed,

Take a look at the post before yours titled

I have just posted about how to use command to duplicate traffic from interfaces like serial, token Ring... (not Ethernet) to another interface to which a sniffer is connected.

I hope this is what you need.
