Error: No functional ports.

Question

I try to run Cisco Packet Tracer, but it gives me this error: "No functional ports". What do I do?

Answer 1

You need to assign an IP to the switch in order to avoid that error. You can do this using the example below:

Switch(config)#int vlan 1
Switch(config-if)#ip address 10.1.1.2 255.255.255.0
Switch(config)#ip default-gateway 10.1.1.1

This is just an example, you need to add your own IP addresses. After this procedure, reboot the PC and restart the application then it should work normally.

Answer 2

you should be "copy run start" after exit on Switch and click ICMP to PC to Switch and worked.

You no need to reboot PC!

Answer 3

you must be complete VLAN configuration this port and put IP address and subnet mask.
