Configuring An 802.1X Guest Vlan - HP 5120 EI Switch Series Configuration Manual

Configuring an 802.1X guest VLAN

Configuration guidelines
Follow these guidelines when configuring an 802.1X guest VLAN:
You can configure only one 802.1X guest VLAN on a port. The 802.1X guest VLANs on different

ports can be different.
Assign different IDs for the voice VLAN, the default VLAN, and the 802.1X guest VLAN on a port, so

the port can correctly process incoming VLAN tagged traffic.
With 802.1X authentication, a hybrid port is always assigned to a VLAN as an untagged member.

After the assignment, do not re-configure the port as a tagged member in the VLAN.
Use Table 6 when configuring multiple security features on a port.

Table 6 Relationships of the 802.1X guest VLAN and other security features
Feature
MAC authentication guest VLAN
on a port that performs MAC-
based access control
802.1X Auth-Fail VLAN on a port
that performs MAC-based access
control
Port intrusion protection on a port
that performs MAC-based access
control
Configuration prerequisites
 Create the VLAN to be specified as the 802.1X guest VLAN.
If the 802.1X-enabled port performs port-based access control, enable 802.1X multicast trigger.

If the 802.1X-enabled port performs MAC-based access control, configure the port as a hybrid port,

enable MAC-based VLAN on the port, and assign the port to the 802.1X guest VLAN as an
untagged member. For more information about the MAC-based VLAN function, see the Layer 2
LAN Switching Configuration Guide.
Configuration procedure
Follow these steps to configure an 802.1X guest VLAN:
To do...
Enter system view
Configure an
802.1X guest
VLAN for one
or more ports
Relationship description
Only the 802.1X guest VLAN take effect.
A user that fails MAC authentication is not
assigned to the MAC authentication guest
VLAN.
The 802.1X Auth-Fail VLAN has a higher
priority
The 802.1X guest VLAN function has
higher priority than the block MAC action
but lower priority than the shut down port
action of the port intrusion protection
feature.
Use the command...

Remarks
—
Required
Use either approach.
By default, no 802.1X guest
VLAN is configured on any port.
