8.2.3 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 | wrr queue1-weight queue2-weight queue3-weight queue4-
weight queue5-weight queue6-weight queue7-weight queue8-weight | sp-wrr queue1-weight
queue2-weight queue3-weight }
Disable queue-scheduler
no queue-scheduler
System supports three types of queue-scheduler mode: Strict-Priority Queue, Strict-Priority
Queue and Weighted Round Robin (SP+WRR) and Weighted Round Robin (WRR).
By default, switch uses Strict-Priority Queue.
The detailed command refers to the corresponding command line reference.
8.2.4 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
Use queue-scheduler cos-map command to configure 4 cos-map relationship of hardware
priority queue and 8 priority of IEEE802.1p protocol
Use following command in global configuration moide.
queue-scheduler cos-map [ queue-number ] [ packed-priority ]
Use following command to display the priority cos-map.
show queue-scheduler cos-map
For example:
! Configure packed-priority 1 to mapped priority 6 of IEEE 802.1p
QTECH(config)#queue-scheduler cos-map 1 6
8.2.5 Flow mirror configuration
Flow mirror is copying the service flow which matches ACL rules to specified monitor interface
to analyse and monitor packet.
Use following command to configure flow mirror.
Configure it in interface configuration mode.
Flow mirror configuration
mirrored-to { [ ip-group { access-list-number | access-list-name } [ subitem subitem ] ] [ link-
group { access-list-number | access-list-name } [subitem subitem ] ] } } [ interface interface-
num ]
Cancel flow mirror configuration
no mirrored-to { [ ip-group { access-list-number | access-list-name } [subitem subitem ] ] [ link-
group { access-list-number | access-list-name } [subitem subitem ] ] } }
Details of this command refers to corresponded command.
