When being executed in Ethernet port view, these two commands apply to the current
Ethernet port only. In this case, the interface-list argument is not needed.
Caution:
z The Guest VLAN function is available only when the switch operates in a port-based
authentication mode.
z Only one Guest VLAN can be configured for each switch.
z The Guest VLAN function is unavailable when the dot1x dhcp-launch command is
configured on the switch, because the switch does not send authentication request
packets.
