I have been looking for the command to view all concurrent active connections or sessions on our Cisco 2911. I want to see what the total connections or sessions are at peak times throughout the day. Does anyone have the command for this? Thanks - Robert
I don't personally have access to a 2911, but they should have a 'show connections' or equivalent command to show you what you're looking for. Netflow is possible on the 2911, that may be a better solution for what you're trying to look at, so you may want to check that out as well. Hope that was helpful!
you may want to read/explore more on FNF (flexible netflow).

#show flow record netflow ipv4 protocol-port
flow record netflow ipv4 protocol-port:
Description: Protocol and Ports aggregation scheme
No. of users: 0
Total field space: 22 bytes
match ipv4 protocol
match transport source-port
match transport destination-port
match flow direction
collect counter bytes
collect counter packets
collect timestamp sys-uptime first
collect timestamp sys-uptime last
If you have tacacs or radius on your router just try this:
show aaa sessions
show aaa users
If you would specify which kind of sessions you want to monitor that would help a lot. The above commands are tracking remote access.
A good buffer could help anyway :
logging buffered 32768 debug
