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
