    Hi there,
    I am trying to configure a Cisco 3548 switch with voice VLAN 20 and then assigning all the 48 ports to it and also giving a switchport access to Vlan 3 on the same interfaces. But, I came across this problem:

    (config)#int fa0/1
    (config-if)#switchport voice vlan 20

    % Invalid input detected at '^' marker. (the marker is at "v" of the voice)

    It is not recognizing the voice command. This is what i get when I do sh vlan:

    SW2#sh vlan
