Port Status and Basic Configuration
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 HP ProCurve switches have the following outbound port queue
structure:
Switch Model Outbound
Port Queues
Switch 6108 4
Series 5300xl Switch 4
Series 4100gl Switch 3
Series 3400cl Switch
Series 2600, 2600-PWR Switch 4
Series 2800 Switch 4
Series 2500 Switch 2
Switches 1600M/2400M/2424M/4000M/8000M 2
As shown below, these port queues map to the eight priority settings specified
in the 802.1p standard.
