2) From this command output, verify that the port you are connected to is up/up as well.
If any of them are up, then enter this interface and issue the shutdowncommand, followed by the no shutdown command.
Issue the show ip interface brief command. Both should be up/up this time. If the port is still showing down/down status, then check the cable or replace it with a good straight-through cable. As an alternative, connect the PC into a different port, in case the port is faulty.
If you are able to ping the switch but still cannot access it through the CNA, choose Connect To in the Connect window, and enter the IP address of the switch in the area next to Connect To. (The IP address of the interface VLAN that is up/up in the output of the show ip interface brief command). With this, you should be able to access it ,and a new window displays a little drawing of a switch.
If you are now unable to access the switch thorugh the CNA, but you are able to ping it, upgrade the software version of your switch to the latest maintenance release.
