14. Copy packet to CPU
User can copy specified packet to CPU according to the need of its QoS strategies.
System realizes QoS function according to accessing control list, which includes: flow monitor,
interface speed limit, packet redirection, priority mark, queue scheduler, flow mirror, flow
statistics and coping packet to CPU.
8.2 QOS Configuration
8.2.1 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
(1) Packet redirection configuration
Packet redirection configuration is redirecting packet to be transmitted to some egress.
Use following command to configure it.
Configure it in global 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.
8.2.2 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 { user-group { access-list-number | access-list-name } [ subitem subitem ] | { [ ip-
group { access-list-number | access-list-name } [ subitem subitem ] ] [ link-group { access-list-
number | access-list-name } [ subitem subitem ] ] } } { cos { pre-value | background | best-effort
| controlled-load | excellent-effort | network-management | spare | video | voice } }
Cancel packet priority configuration
no traffic-priority { user-group { access-list-number | access-list-name } [ subitem subitem ] | { [
ip-group { access-list-number | access-list-name } [ subitem subitem ] ] [ link-group { access-
list-number | access-list-name } [ subitem subitem ] ] } }
Switch can support to mark 802.1p priority to the packet (the cos value of traffic-priority).
Details of this command refers to corresponded command.
