Configuring Queue Scheduling - H3C S9500 Series Operating Manual

Operation Manual – QoS
H3C S9500 Series Routing Switches
For service processor boards, perform the following configurations in VLAN view.
Configure traffic redirecting on
packets matching Layer 3
ACL rule.
Remove this traffic redirecting
configuration on the packets
matching Layer 3 ACL rule.
The system-index index keyword-argument combination here is the system index for
an ACL rule. When delivering a rule, the system assigns a globally unique index to it, for
convenience of later retrieval. You can also assign a system index for it when delivering
an ACL rule with this command, but the index value may change while the system is
running. However, you are not recommended to assign a system index if not urgently
necessary.
Note:
Traffic redirecting setting is only available for the permitted rules in the ACL.
The packet redirected to the CPU cannot be forwarded normally.
You can achieve policy route by selecting the next-hop keyword.
Before executing the traffic-redirect command on a service processor board, you
must first configure traffic redirecting in Ethernet port view to redirect the packets in
Layer 3 to the service processor board and specific VLAN.
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 Scheduling

Each port supports eight output queues except that ports of GV48D/GP48D/XP4
non-wire-speed boards only support four queues. The switch puts the packets into the
queues according to the local precedence of packets. Queue scheduling is used to
resolve problems of resource contention by many packets. The switch supports SP
algorithm and WRR algorithm.
Different output queues at the port may use different algorithms. The switch supports
three scheduling modes:
To do... Use the command...
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-hop
ip-addr1 [ ip-addr2 ] [ invalid { forward | drop } ]
[ slot slot-id ] } }
undo traffic-redirect inbound ip-group
{ acl-number | acl-name } [ rule rule ] [ slot slot-id ]
