3Com Switch 8800 Family Configuration Guide

196 CHAPTER 22: QOS CONFIGURATION
For service processor cards, perform the following configurations in VLAN view.
system-index index 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.
n
■ Traffic redirection 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 card,
you must first configure traffic redirection in Ethernet port view to redirect the
packets in Layer 3 to the service processor card and specific VLAN.
■ Multicast packets are not allowed to be redirected to the service processor
cards.
See the corresponding Command Manual for details of the commands. Refer to
the "VLAN&QinQ" section in the manual for detailed information on the
traffic-redirect { nested-vlan | modified-vlan } command.
Configuring Queue
Scheduling
Each port supports eight outbound queues except that ports of
GV48D/GP48D/XP4 non-wire-speed cards 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.

Tabl e 170 Configure traffic redirection
Operation Command
Configure traffic redirection
on packets matching Layer 3
ACL rule.
traffic-redirect { inbound | outbound } ip-group {
acl-number | acl-name } [ rule rule [ system-index index ] ] {
cpu | next-hop ip-addr1 [ip-addr2] [ invalid { forward |
drop } ] } [ slot slotid ]
Remove this traffic redirection
configuration on the packets
matching Layer 3 ACL rule.
undo traffic-redirect inbound ip-group { acl-number |
acl-name } [ rule rule ] [ slot slotid ]
