Outbound Port Queues And Packet Priority Settings - ProCurve 2626 Management And Configuration Manual

Configuring Port-Based Priority for Incoming Packets on the 4100gl and 6108 Switches
member of the VLAN, the packet carries its priority setting to the next,
downstream device. If the outbound port is not configured as a tagged member
of the VLAN, then the tag is stripped from the packet, which then exits from
the switch without a priority setting.

Outbound Port Queues and Packet Priority Settings

Ports on the ProCurve switches have the following outbound port queue
structure:
