This is a very basic question.

I have configured a 3560, vlan 1 with an IP address of, set fa0/1 to access vlan 1

I have set my laptop up with IP address, default gateway

From the laptop I can PING and Telnet into the switch, however, from the switch I cannot PING or open up a TFTP session with the TFP server running on the laptop

I configured fa0/1 as:


switchport mode access

switchport access vlan 1

no shut

However, if I do a show run, there is only one line listed:

Interface Fa0/1

switchport mode access

The switchports are by default in vlan 1, so the command "switchport access vlan 1" is/was already in there, hence you don't see the command when you do a show run on the interface.

Check the firewall on the PC. I am pretty sure its the Windows firewall or other firewall blocking it. Disable that and it should start working.
