S9700 Core Routing Switch
Configuration Guide - SPU
1.1 Overview of SPU Pre-Configuration
This section describes how the SPU is connected to the S9700 switch with XGE interfaces.
Connection Mode
If the SPU is installed in slot 5 on the S9700 switch, virtual connections are set up between XGE
5/0/0 on the S9700 and XGE 0/0/1 on the SPU, and between XGE 5/0/1 on the S9700 and XGE
0/0/2 on the SPU. All the traffic imported or mirrored to XGE 5/0/0 and XGE 5/0/1 are processed
by the SPU, as shown in
Figure 1-1 Mapping between interfaces on the S9700 and SPU
Flow Import Mode on the SPU
The SPU can process the following services:

When you use the SPU for the first time, the service type is not configured, and you must
configure a service type for the SPU.
To use the firewall, load balancing, or IPSec, configure Layer 2 or Layer 3 flow import to
implement data exchange between the S9700 and the SPU.
To use the NetStream service, configure port mirroring or traffic mirroring so that traffic on the
S9700 is mirrored to the SPU.
Only one of the preceding services can be enabled on an SPU at a time.
You can install multiple SPUs on an S9700 switch to provide different types of services.
