9.2 QOS Configuration

9.2.1 QoS Configuration list

QOS Configuration includes:

· Packet redirection configuration

· Priority configuration

· Queue-scheduler configuration

· The cos-map relationship of hardware priority queue and priority of IEEE802.1p protocol

· Flow mirror configuration

· Flow statistic configuration

· Packet rewrite-vlan configuration

· Packet insert-tag head configuration

· Define corresponded ACL before configuring QoS.

9.2.2 Packet redirection configuration

Packet redirection configuration is redirecting packet to be transmitted to some egress.

Use following command to configure it.

Configure it in interface configuration mode.

Redirection

traffic-redirect { [ ip-group { access-list-number | access-list-name } [ subitem subitem ] ]

[ link-group { access-list-number | access-list-name } [ subitem subitem ] ] } } { interface

interface-num }

Cancel redirection

no traffic-redirect { [ ip-group { access-list-number | access-list-name } [ subitem subitem ] ]

[ link-group { access-list-number | access-list-name } [ subitem subitem ] ] } }

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.

9.2.3 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.

Mark packet priority

traffic-priority { [ ip-group { access-list-number | access-list-name } [ subitem subitem ] ]

[ link-group { access-list-number | access-list-name } [ subitem subitem ] ] } } { [ dscp dscp-value |

precedence { pre-value | from-cos } ] [ cos { pre-value | from-ipprec } ] [ local-precedence
