Operation Manual – QoSH3C S9500 Series Routing Switches Chapter 1 QoS Configuration1-17For service processor boards, perform the following configurations in VLAN view.To do... Use the command...Configure traffic redirecting onpackets matching Layer 3ACL rule.traffic-redirect inbound ip-group { acl-number |acl-name } { { rule rule { cpu [ slot slot-id ] |next-hop ip-addr1 [ ip-addr2 ] [ invalid { forward |drop } ] | system-index index { cpu [ slot slot-id ] |next-hop ip-addr1 [ ip-addr2 ] [ invalid { forward |drop } } } | { cpu [ slot slot-id ] } | { next-hopip-addr1 [ ip-addr2 ] [ invalid { forward | drop } ][ slot slot-id ] } }Remove this traffic redirectingconfiguration on the packetsmatching Layer 3 ACL rule.undo traffic-redirect inbound ip-group{ acl-number | acl-name } [ rule rule ] [ slot slot-id ]The system-index index keyword-argument combination here is the system index foran ACL rule. When delivering a rule, the system assigns a globally unique index to it, forconvenience of later retrieval. You can also assign a system index for it when deliveringan ACL rule with this command, but the index value may change while the system isrunning. However, you are not recommended to assign a system index if not urgentlynecessary.Note:z Traffic redirecting setting is only available for the permitted rules in the ACL.z The packet redirected to the CPU cannot be forwarded normally.z You can achieve policy route by selecting the next-hop keyword.z Before executing the traffic-redirect command on a service processor board, youmust first configure traffic redirecting in Ethernet port view to redirect the packets inLayer 3 to the service processor board and specific VLAN.z Multicast packets are not allowed to be redirected to the service processor boards.See the corresponding Command Manual for details of the commands.1.2.6 Configuring Queue SchedulingEach port supports eight output queues except that ports of GV48D/GP48D/XP4non-wire-speed boards only support four queues. The switch puts the packets into thequeues according to the local precedence of packets. Queue scheduling is used toresolve problems of resource contention by many packets. The switch supports SPalgorithm and WRR algorithm.Different output queues at the port may use different algorithms. The switch supportsthree scheduling modes:
