qos tagprio This command displays or sets the default tag priority (used when adding a
tag to untagged frames) for specified ports.
SYNTAX
qos tagprio [port-list] [tag-priority]
port-list - A specific port or range of ports. (Range: 1-28, or all)
tag-priority - The default priority used when adding a tag to
untagged frames. (Range: 0-7)
DEFAULT SETTING
0
COMMAND USAGE
◆ The default tag priority applies to untagged frames 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.
◆ Inbound frames that do not have VLAN tags are tagged with the input
port’s default ingress tag priority, and then placed in the appropriate
priority queue at the output port. (Note that if the output port is an
untagged member of the associated VLAN, these frames are stripped of
all VLAN tags prior to transmission.)

qos qcl port This command displays or sets the QCL assigned to specified ports.
SYNTAX
qos qcl port [port-list] [qcl-id]
port-list - A specific port or range of ports. (Range: 1-28, or all)
qcl-id - A Quality Control List which classifies ingress frames based
on criteria including Ethernet type, VLAN ID, TCP/UDP port, DSCP,
ToS, or VLAN priority tag (see the qos qcl add command on
page 314). Traffic matching the first entry in the QCL is assigned to
the traffic class (output queue) defined by that entry. Traffic not
matching any of the QCEs are classified to the default QoS Class for
the port. (Range: 1-28)
