Hi..

Is it possible to mirror a WAN interface on the router.Means if the packets are coming on one serial interface can go to another mirrored serial interface at the same time. i need to analyze A WAN link with out putting the analyzer in between the WAN link. So i am thinking to mirror the another serial interface on the same router to see the packets.

Thanks.

Hi,

no, to the best of my knowlege we do not have a span port like facility on the router.

You can not monitor a serial interface on another one. You must connect the sniffer into the serial line you need to monitor.

thanks...

I believe IOS 12.3 has a feature to dump packets from serial interfaces to another interface connected to IDS'es. This can also be a periodic sample so as not to overload the cpu.
