Dual-Mode Vlan Ports - HP 9304m Installation And Getting Started Manual

HP9300(config-vlan-7)# pvlan type primary
HP9300(config-vlan-7)# pvlan mapping 901 ethernet 3/2
HP9300(config-vlan-7)# pvlan mapping 902 ethernet 3/2
HP9300(config-vlan-7)# pvlan mapping 903 ethernet 3/2
NOTE: You also can specify the primary port and other ports on the same command line. In this example, the
command tagged ethernet 3/2 ethernet 3/5 to 3/6 is equivalent to the pair of tagged commands shown above for
the same ports.

Dual-Mode VLAN Ports

Configuring a tagged port as a dual-mode port allows it to accept and transmit both tagged traffic and untagged
traffic at the same time. A dual-mode port accepts and transmits frames belonging to VLANs configured for the
port, as well as frames belonging to the default VLAN (that is, untagged traffic).
NOTE: If you plan to use dual-mode ports, do not configure any of the ports in the default VLAN in a trunk group
and do not configure the dual-mode ports in a trunk group.
For example, in Figure 7.19, port 2/11 is a dual-mode port belonging to VLAN 20. Traffic for VLAN 20, as well as
traffic for the default VLAN, flows from a Switch to this port. The dual-mode feature allows traffic for VLAN 20 and
untagged traffic to go through the port at the same time.

USING THE CLI
To enable the dual-mode feature on port 2/11 in Figure 7.19:
HP9300(config)# vlan 20
HP9300(config-vlan-20)# tagged e 2/11
HP9300(config-vlan-20)# tagged e 2/9
HP9300(config-vlan-20)# int e 2/11
HP9300(config-if-e100-2/11)# dual-mode
HP9300(config-if-e100-2/11)# exit
Syntax: [no] dual-mode
