Dot1X Handshake - 3Com 5500-EI PWR Reference Manual

If you specify the interface-list argument, these two commands apply to the specified ports.
In Ethernet port view, the interface-list argument is not available and these two commands apply to only
the current Ethernet port.
The guest VLAN function is available only when the switch operates in the port-based
authentication mode.
Only one guest VLAN can be configured on a switch.
The guest VLAN function is unavailable when the dot1x dhcp-launch command is executed on
the switch, because the switch does not send authentication request packets in this case.
Examples
# Configure the switch to operate in the port-based authentication mode.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] dot1x port-method portbased
# Enable the guest VLAN function for all the ports.
[Sysname] dot1x guest-vlan 1
