possibilities to view incoming UDP or TCP sessions?
In case of a Cisco router, what are the possibilities for viewing incoming and outgoing UDP/TCP sessions intended for interfaces in the router? "debug ip packet" should be one option. For example on Cisco 7200 platform one could use "show udp" in order to list ongoing UDP sessions if I'm not mistaken? And for TCP one can use "show tcp brief numeric". Are there any other options for determing UDP and TCP packets intended to router? For example viewing the netflow data from the router if it's configured?
