switchport, switchport mode trunk

HI every body!

Let say we have a multilayer switch.We want to configure f0/1 as trunk.

Please consider the following configuration :

switch(config) int f0/1

Switch(config-if) switchport mode trunk

will setting the trunk mode on fo/1 automatically set the port for layer 2 operation or we need to configure the command" switchport"?

thanks a lot!

Hi Sarah,

If your port is configured with no switchport, it will not take the switchport mode trunk command. In another word, switchport mode trunk is L2 only.

HTH,

You need to do the following:

switch(config) int f0/1

switch(config) switchport

Switch(config-if) switchport mode trunk
