Juniper Networks 5000 SERIES manual Secure Port Modules, 5000-8G SPM

Chapter 1 Overview

Secure Port Modules

Secure Port Modules (SPMs) perform general packet processing and device connection tasks for devices that communicate with the NetScreen-5000 Series. These modules are based around the GigaScreen-II ASIC.

SPMs handle packets as they enter and exit the system, providing packet parsing, classification, and flow-level processing. SPMs also provide encryption, decryption, Network Address Translation (NAT), and session lookup features. When packets require processing beyond that provided by an SPM, the NetScreen-5000 Series hands them off to the management module for further processing.

There are currently two SPM models:

•The 5000-8G SPM, with eight mini-GBIC Gigabit Ethernet ports.

•The 5000-2G24FE SPM, with two mini-GBIC Gigabit Ethernet ports and 24 10/ 100 Ethernet ports.

The 5000-8G SPM

The 5000-8G SPM provides eight Gigabit Ethernet mini-Gigabit Interface Converter (GBIC) ports using hot-swappable transceivers. The 5000-8G delivers up to 4 Gigabits- per-second (Gbps) of firewall and up to 2 Gbps of Virtual Private Network (VPN) capacity. This module is also capable of supporting a total of four aggregate interfaces.

(For details on connecting or removing a mini-GBIC transceiver and connecting and disconnecting a Gigabit Ethernet cable, see Chapter 4, Servicing the Device.)

The 5000-8G provides port Link and Activity LEDs in addition to Power and Status LEDs.
