Capturing VPN traffic on Cisco 857W

[support]

Hi,

I need to be able to capture VPN traffic on the 857 router using Netflow or other tools.

WHat interfaces show I be monitoring.

Thanks

Hello Kieren,

if your "WAN" interface is a LAN interface and you have a Cisco switch you can configure the switch to mirror traffic of the port where you connect the C857 WAN port to another port where you connect a laptop with a SW protocol analyzer.

IF you refer to embedded packet capture it shouldn't be supported on the 857 according to

http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6555/ps9913/datasheet_c78-502727.html

that lists C7200 and ISR as supported platforms.

Hope to help

Giuseppe
