specified ports.

ports of the switch.
z If you specify the interface-list argument, these two commands apply to the
specified Ethernet ports.
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.
