can set the default priority for each interface, and configure the mapping of frame
priority tags to the switch’s priority queues.
Layer 2 Queue Settings
Setting the Default Priority for Interfaces
You can specify the default port priority for each interface on the switch. All untagged
packets entering the switch are tagged with the specified default port priority, and
then sorted into the appropriate priority queue at the output port.
Command Usage
• This switch provides four priority queues for each port. It uses Weighted Round
Robin to prevent head-of-queue blockage.
• The default priority applies for an untagged frame received on a port set to accept
all frame types (i.e, receives both untagged and tagged frames). This priority does
not apply to IEEE 802.1Q VLAN tagged frames. If the incoming frame is an IEEE
802.1Q VLAN tagged frame, the IEEE 802.1p User Priority bits will be used.
• If the output port is an untagged member of the associated VLAN, these frames are
stripped of all VLAN tags prior to transmission.
Command Attributes
• Default Priority
10
– The priority that is assigned to untagged frames received on
the specified interface. (Range: 0-7; Default: 0)
• Number of Egress Traffic Classes – The number of queue buffers provided for
each port.
Web – Click Priority, Default Port Priority or Default Trunk Priority. Modify the default
priority for any interface, then click Apply.
