Hello!
I have a little problem...I want to see the maximum tcp connections that I had on my Cisco.
I tried using show ip statistics but it's not working
I have a Cisco Catalyst 3750G (WS-C3750G-48TS)
IOS -> Version 12.2(52)SE, RELEASE SOFTWARE (fc3)
Can someone tell how can I find this information ?
Thank you.

Do you want to know how many maximum TCP connections your device supports or how many it is currently running?

I want to see how many it had.
From what I can see I can use show tcp statistics to see the current ones.
But I want to see the maximum number ever.

Hi Valentin,
"show tcp statistics" shows the TCP connections established to or from the switch itself, if that's what you are interested, the out gives you total rcvd and sent:
This one was taken when only 1 tcp connection was established to this switch, yet you see total rcvd of 917.
G#show tcp statistics
Rcvd: 917 Total, 1 no port
0 checksum error, 0 bad offset, 0 too short
596 packets (1338 bytes) in sequence
7 dup packets (60 bytes)
2 partially dup packets (2 bytes)
0 out-of-order packets (0 bytes)
0 packets (0 bytes) with data after window
0 packets after close
0 window probe packets, 0 window update packets
0 dup ack packets, 0 ack packets with unsend data
423 ack packets (15448 bytes)
Sent: 3602 Total, 0 urgent packets
2702 control packets (including 1340 retransmitted)
611 data packets (16432 bytes)
46 data packets (6072 bytes) retransmitted
243 ack only packets (219 delayed)
0 window probe packets, 0 window update packets
1339 Connections initiated, 19 connections accepted, 18 connections established
1358 Connections closed (including 1354 dropped, 1339 embryonic dropped)
1386 Total rxmt timeout, 1339 connections dropped in rxmt timeout
0 Keepalive timeout, 0 keepalive probe, 0 Connections dropped in keepalive
You can run "show tcp brief" to see alive connections
Hope it helps!!
