Note:
Before initiating any of these QoS configuration tasks, you should first define the
corresponding ACL. Then you can achieve packet filtering just by activating the right
ACL.
To configure packet filtering, you need only to activate corresponding ACL. For
more information, see ACL Configuration in the QoS ACL Volume.
In QoS configuration (including packet filtering, traffic policing, priority marking,
traffic redirecting, traffic mirroring, and traffic accounting), if the specified advanced
ACL has been occupied by IDS, QoS action cannot be delivered normally.
The four ports (numbered 0 to 3) on an XP4B or XP4CA board each support four
queues (queue 0 to 3) and support the configuration for queue scheduling.
On an XP4B or XP4CA board, the following configurations can only be performed
on port 0 and 2: applying user-defined flow template, port local precedence, packet
filtering, priority marking, traffic policing, traffic redirecting, traffic mirroring, and
traffic accounting. When such a configuration is performed on port 0, it takes effect
on both port 0 and 1. Likewise, when such a configuration is performed on port 2, it
takes effect on both port 2 and 3.
With traffic policing configured on a XP4B or XP4CA board, port 0 and 1 share the
same bandwidth, and port 2 and 3 do likewise. That is, port 0 and 1 share the traffic
parameter settings on port 0, and port 2 and 3 share the traffic parameter settings
on port 2.
On an XP4B or XP4CA board, executing the traffic-statistic command on port 0
will collect traffic statistics on both port 0 and 1, and executing the command on port
2 will collect traffic statistics on both port 2 and 3.
Ports on XP4B and XP4CA boards do not support traffic shaping (traffic-shape).
Caution:
The syntax of the QoS configuration command used for service processor boards
(LSB1NATB0 boards in the context of this document) is somewhat different from
that for interface boards. See related description in the manual.
The service processor boards now supported by the S9500 series have no egress
interface. Therefore, they do not support the configuration commands in Ethernet
port view.
Service processor boards do not support Layer 2 ACL.
Some of QoS terms are listed in the following table.
