Hello, i've got two Catalyst 3950 connected on stack for the production network and another 3950 catalyst for the test network. There is a crossover cable from the Catalyst of test network to one of the production catalyst in order to give them conectivity.
Now, somebody wants to comunicate from a workstation on the test network to a server on the production network. I can perfectly ping, but this user tells me that he needs to conect using tcp ports 1433 and 5084.
Is there anyway i can test those ports from the switches?

Hello Francisco,
you can test by using
telnet ip-address tcp-port-number
On IOS based switches
to see if you can access the service on the specified port
Hope to help

NetworkSwitch1#telnet 192.168.165.XX 5084
Trying 192.168.165.64, 5084 ... Open
NetworkSwitch1#telnet 192.168.165.xx 1433
Trying 192.168.165.64, 1433 ... Open
Hi, i got this answer from the switch, i gues that means the port is listening on the specific machine. That means tcp port is open i guess?
