depending what your hardware/ios is you will need to check what features you have available and what it supports

Most routers are limited that they cannot support SPAN but 3845s can or you could look into using the feature RITE

Some routers also support monuitor capture buffer

Dear Mark,

Thank you very much for your reply.

We have started using the product http://www.unleashnetworks.com/.

We fetch the logs from the Netflow. It analyses well.

It is under observation to check the performance...
