Gigabit Ethernet Circuit Board
PIX Firewall supports 1000 Mbps (Gigabit) Ethernet. The Gigabit Ethernet circuit board uses the
gb-ethernet device name and only has one hardware speed and the following duplex options:
• 1000SXfull—Forces full-duplex operation
• 1000BaseSX—Forces half-duplex operation
• 1000auto—Auto negotiates full or half duplex
Note We highly recommend that you use a GE failover link when connecting the PIX 525 with GE interfaces.
