I'm migrating all my cisco PIX used as VPN peers by Cisco ISR routers.

I would like to refind a bit same information.

does it exist something like "sh conn" on routers ? to see all connections : udp, tcp, icmp.. ?

if you know how to get that, I'm interested.

thanks, but like I said before I use ISR only as VPN peers, so there is none nat

Sorry about that. Try enabling IP Accounting. That should give you the connections you're looking for. I'm not 100% sure it will give you the port numbers though.

thanks that works well on my tunnel interfaces

you are right, there is no port indication :-( (if you have an idea)

but it's not real time traffic, right ? it keeps history :-(

it's better than nothing, but I try to find better
