By default, switch uses Strict-Priority Queue.

The detailed command refers to the corresponding command line reference.

7.2.7 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

7.2.8 Configure the mapping relationship between DSCP and 8

priority in IEEE 802.1p

DSCP is the high 6 byte in ToS bit which is in the range of 0-63. The default mapping

relationship is that all DSCP map to priority 0.

Use this command to configure the mapping relationship between DSCP and 8 priority in IEEE

802.1p.

Configure it in global configuration mode:

queue-scheduler dscp-map [ dscp-value ] [ packed-priority ]

Example

!Configure dscp 2 to map to priority 5

QTECH(config)#queue-scheduler dscp-map 2 5

7.2.9 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.
