Class of Service Commands
The commands described in this section allow you to specify which data packets
have greater precedence when traffic is buffered in the switch due to congestion.
This switch supports CoS with four priority queues for each port. Data packets in a
port’s high-priority queue will be transmitted before those in the lower-priority
queues. You can set the default priority for each interface, the relative weight of each
queue, and the mapping of frame priority tags to the switch’s priority queues.
Priority Commands
(Layer 2)
This section describes the commands used to configure Layer 2 traffic priority on the
switch.

Priority (Layer 2)
Configures default priority for untagged frames, sets queue weights,
and maps class of service tags to hardware queues
4-244
Priority (Layer 3 and 4)
Sets the default priority processing method (CoS, IP Precedence or
DSCP); and maps TCP ports, IP precedence tags, or IP DSCP tags to
class of service values
