1.1 Introduction to the SPUThe SPU provides service functions such as load balancing, firewalls, NAT, IPSec, NetStream
in diverse network application scenarios. These functions are mainly used on industry networks.
In modern enterprises, video conferences and video monitoring devices are widely used; shared
files such as pictures and high-definition video files are transmitted on intranets; servers and
storage devices need to back up data periodically. With the preceding requirements of
enterprises, people raise higher requirements for the reliability, security, and simplified operation
and management of industry networks.
As the VAS unit of the S9300, the SPU provides diverse VAS functions for industry networks,
such as load balancing, IPSec VPN, NAT, firewalls, and two-node cluster backup. In addition,
the SPU provides solutions to the network security of communities, interconnection between
communities, and wireless local area networks (WLANs). The SPU provides the high-efficient
load balancing solution, which accelerates the response speed of the IT system, shortens the
application delay, and balances the traffic on network devices. In this manner, the service
reliability can be improved and services can be expanded flexibly. Multiple firewalls and the
IPSec VPN facilitates integration of the VLAN switching technology of switches with security
network technologies, thus providing security services and implementing the secure and
encrypted interaction among departments of customers. NetStream provides data support for
charging and settlement, network planning, and network operation and management for most
carriers.
1.2 Functions and Typical Applications of the SPUThe SPU can be installed in any LPU slot of the S9300 to process the packets that are transmitted
from the MPU of the S9300. The SPU is applicable to load balancing, NAT, firewall, IPSec,
and NetSream solutions.
Currently, the SPU supports only one board, namely, VAMPA, which is installed in the LPU
slot of the S9300. The system transmits the packets to be processed to the SPU. Then the SPU
processes the packets related to the VASs. Figure 1-1 shows the processing procedure.

As shown in Figure 1-2, an Intranet user accesses the internal server that is deployed in
the group of load balancing servers through the external network. The group is composed
of three servers. As the load balancing (LB) device, the Switch implements load balancing
at layers from L4 to L7. The service load varies according to servers. When one or more
servers are faulty, the system automatically switches services to normal servers so that
services are not interrupted. In this manner, network faults are reduced and the reliability
of service processing is improved.
l Egress link load balancing

As shown in Figure 1-4, an IPSec tunnel is set up between Switch A and Switch B. In this way,
data flows of intranet user A and intranet user B can be protected when being transmitted on
insecure networks. IPSec allows network users or administrators to control the granularity of
security services between peers. The Security Association (SA) can be established manually or
in IKE negotiation mode. The SA provides security protection for different data flows.

As shown in Figure 1-5, IP addresses of PC1 and PC2 on the intranet can be mapped to thepublic IP addresses on the external network through NAT. In this way, users on private networks
can access external networks, thus saving public IP addresses. The NAT mapping table is used
to limit hosts on internal networks that access hosts on external networks.
By configuring the internal servers, you can map the corresponding external IP addresses and
port numbers to internal servers. In this manner, users on external networks can access internal
servers. For example, an enterprise provides World Wide Web (WWW), File Transfer Protocol
(FTP), and Simple Mail Transfer Protocol (SMTP) services externally.

As shown in Figure 1-7, the Switch functions as the firewall in transparent mode. In this
case, all interfaces are L2 interfaces and the network is divided into multiple access zonesthrough different VLANs. All PCs in a zone share the same network segment. The packet
filtering, attack defense, and traffic monitoring policies are defined for different VLANs
on the Switch. For example, PC A can access Zone B and Zone C. PC B can send packets,
whereas the packets cannot pass the firewall.

As shown in Figure 1-8, SPU 1 and SPU 2 are installed on the Switch. VRRP is enabled
on these two SPUs to provide a virtual IP address for the switch and thus to back up services.
When SPU 1 functions as the master, data flows are transmitted to the Internet through
SPU 1. At the same time, data is synchronized from SPU 1 to SPU 2. After SPU 1 becomes
faulty, data flows are transmitted to the Internet through SPU 2.

interfaces of PEs. Users can also collect statistics on MPLS packets by deploying NetStream
on network-side interfaces of PEs and P devices. According to the analysis result of the
statistics, users can understand the composition and mode of the MPLS service accurately.l Monitoring traffic carried by a tunnel

As shown in Figure 1-10, if a user collects statistics on the traffic transmitted through a
tunnel on physical interfaces of the switch, the user cannot differentiate the traffic carried
by the tunnel. In this case, the user needs to collect traffic statistics by using NetStream
twice, that is, before the traffic enters the tunnel and after the traffic exits the tunnel. In thisway, the user can accurately analyze the traffic composition in the tunnel.

with other boards and causing failures of the running boards.
l When swapping an SPU, do not touch the parts on the SPU to prevent it from being
damaged.
2. Hold the two ejector levers and insert the SPU smoothly into the chassis along the guide
rail of the slot, as shown in (1) ofFigure 5-2. Push the SPU until the bayonets of the ejector
levers touch the edges of the chassis.
3. Secure the bayonets of the ejector levers on the edges of the chassis, and then push the
ejector levers inwards until you hear a click, as shown in (2) ofFigure 5-2.

Step 6 Connect the cables to the corresponding interfaces in the original sequence.
Step 7 Check the running status of the new SPU.
In normal situations, after the new SPU is installed into the chassis, the SPU automatically
communicates with the MPU. In this case, check the running status of the new SPU as follows:
l If the RUN/ALM indicator on the panel of the SPU is green and blinks at the frequency of
0.5 Hz, it indicates that the SPU is running normally.
l You can check the alarms. In normal situations, the system does not generate any alarm
related to the new SPU.
l Run the display device command on the client after logging in to the SPU to view the running
status of the new SPU. If the output is displayed as follows, it indicates that the SPUs in the
corresponding slots are running normally.
