DETAILED STEPS
Verifying a Fast Ethernet Interface as Layer 2 Access
Use the show running-config interface command to verify the running configuration of the interface,
as shown below:
Router#show running-config interface fastethernet 0/1/2
Building configuration...
Current configuration: 76 bytes
!
interface FastEthernet0/1/2
switchport access vlan 3
no ip address
end
Use the show interfaces command to verify the switchport configuration of the interface, as shown
below:
Router#show interfaces f0/1/0 switchport
