Cisco 2911 ISR - View active Concurrent connections

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

Hi 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!

Kindest Regards,

Alan

Hi,
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 :

Conf t
logging buffered 32768 debug
End

I am looking to see if I can show the active concurrent TCP connections. Does this help define what I am trying to do on this?

I know this is about 6 years after the OP was posted however, have you tried this command? 

show ip sockets

Hope this helps.
