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.
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 5000-8G 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.
