Instruction :
Use this command to redirect the data packet which matched specified accessing list regulations (it is only
be effective for permit rules of accessing list).
Details of this command refers to corresponded command.

Priority configuration
Traffic priority configuration is the strategy of remark priority for matching packet in ACL, and the marked
priority can be filled in the domain which reflect priority in packet head.
Use following command to configure priority mark configuration.
Configure it in global configuration mode.

System will mark IP priority (precedence specified value of traffic-priority command), DSCP(dscp specified
value of traffic-priority command), 802.1p priority(that is cos value of traffic-priority command). User can mark
different priority for packet according to real QoS strategy. Switch can locate packet to interface outputting queue
according to the 802.1p priority and also can locate packet to corresponding outputting queue according to the
specified local priority in traffic-priority command (local-precedence specified value). If both 802.1p priority and
local priority are configured, 802.1p priority will be precedent to use.
Details of this command refers to corresponded command.
14.2.4
Queue-scheduler configuration
When network congestion, it must use queue-scheduler to solve the problem of resource competition.
Use following command to configure queue-scheduler.
Configure it in global configuration mode.
Configure queue-scheduler
queue-scheduler

strict-priority

}
Disable queue-scheduler
no queue-scheduler
System supports two types of queue-scheduler mode : Strict-Priority Queue, and Weighted Round Robin
(WRR).
By default, switch uses Strict-Priority Queue.
The detailed command refers to the corresponding command line reference.
14.2.5
The cos-map relationship of hardware priority
queue and priority of IEEE802.1p protocol
There are 4 hardware priority queues which are from 0 to 3, of which 3 is the
The default mapping is the mapping defined by 802.1p :
802.1p : 0 1 2 3 4 5 6 7
packed-priority : 0 0 1 1 2 2 3 3
