ip route 0.0.0.0 0.0.0.0 10.0.0.1

1) from the port 20 I connected the laptop with ip address 10.0.0.11 255.255.255.0 and gw 10.0.0.1

but I can't ping 10.0.0.1

2) telnet to the switch (console) I can ping 10.0.0.2 and 10.0.0.11 but I can't ping 10.0.0.1

Any helps I am really appreciated that

If the switch is a layer-2 switch you don't need to have:

ip route 0.0.0.0 0.0.0.0 10.0.0.1 command. 

All you need is a default-gateway command which you already have.

What device has the gateway IP address (10.0.0.1)?

Also can you post the config from that device and the uplink port from the switch to that device?
