Show concurrent sessions

[boboi]

Is there any command that can show an interface's concurrent session? We are planning to buy a firewall that is why we need this data so that we can choose the right firewall that can satisfy our requirement.

you can use the 'show connection' command on the PIX

Thanks gconnect. But I can't do that in a Cisco 2621XM. I guess I have to rephrase my question to: "How can I see the concurrent sessions in an interface of a Cisco 2600 series router?"

Try "show tcp" or "show users"

if you are looking for users logged into the router itself
then you can use the 'sho users' command.

if this is a router connected to the Internet and NAT is used, then issuing the 'show ip nat translations' will show you everyone how has made a connection through the Router. also using CBAC and enabling 'audit trail logging' can show you concurrent connections, although I usually turn it off because it becomes so much info that i don't look at it anymore.

"CBAC also generates real-time alerts and audit trails. Enhanced audit trail features use SYSLOG to track all network transactions; recording time stamps, source host, destination host, ports used, and the total number of transmitted bytes, for advanced, session-based reporting"

There is no easy was to see whats going from the router. One recommendation would be to mnitor the port the router is connected to with a sniffer to capture the packets. The other is to insert the firewall and log all the traffic. If your looking on how to spec a firewall you kinda of need to think of performance and how many users you will be supporting.
