HP A5120 EI Series Configuration Guide

108
NOTE:
 To change the link type of a port from trunk to hybrid or vice versa, you must set the link type to access first.
 After configuring the PVID for a trunk port, you must use the port trunk permit vlan command to configure the
trunk port to allow packets from the PVID to pass through, so that the egress port can forward packets from the
PVID.
 After you use the port link-type { access | hybrid | trunk } command to change the link type of an interface,
the loopback detection action configured on the interface by using the loopback-detection action command will
be restored to the default. For more information about the loopback-detection action command, see the Layer
2—LAN Switching Command Reference .
 After you configure a command on a Layer 2 aggregate interface, the system starts applying the configuration to
the aggregate interface and its aggregation member ports. If the system fails to do that on the aggregate
interface, it stops applying the configuration to the aggregation member ports. If it fails to do that on an
aggregation member port, it skips the port and moves to the next port.
Assigning a hybrid port to a VLAN
A hybrid port can carry multiple VLANs. You can assign it to a VLAN in interface view (including Ethernet
interface view, Layer 2 aggregate interface view) or port group view.
Follow these steps to assign a hybrid port to one or multiple VLANs:

subsequent configurations apply
to all ports in the port group.
 In Layer 2 aggregate interface

configurations apply to the Layer

member ports.

Assign the hybrid port(s) to the

Required
By default, a hybrid port allows only
packets of VLAN 1 to pass through
untagged.
Configure the PVID of the hybrid
port
port hybrid pvid vlan vlan-id
Optional
VLAN 1 is the PVID by default.
