Filtering Packets

[hassnain]

Hi,

Is there any option to find the contents of a packet passing across a router.Data type and data portion in the packet.I meant any option in Cisco IOS.

Thanks.

There is no option on Cisco IOS as such, but you do have choice to use some tools like Sniffer and Etherreal, which help you to read the packets and analyse them.
