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 four SPM models:
•The 5000-8G SPM provides eight 1-Gigabit Small Form Factor Pluggable (SFP) mini-Gigabit Interface Converter (GBIC) Ethernet ports. This SPM is supplied with SX gigabit fiber transceivers.
•The 5000-2G24FE SPM provides two mini-GBIC Gigabit Ethernet ports and 24 10/100 Ethernet ports. This SPM is supplied with two SX gigabit fiber transceivers.
•The 5000-8G2 SPM provides eight 1-Gigabit mini-GBIC Ethernet ports. This SPM is supplied with SX gigabit fiber transceivers.
•The 5000-2XGE SPM provides two 10-Gigabit Form Factor Pluggable (XFP) mini-GBIC Ethernet ports. The transceivers for this SPM must be purchased separately.
The 5000-8G SPM
The 5000-8G SPM provides eight 1-Gigabit SFP mini-GBIC Ethernet ports using hot-swappable transceivers. The 5000-8G SPM 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, with up to two ports for each aggregate interface.
(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 SPM provides port Link and Activity LEDs in addition to Power and Status LEDs.
