Features
The Passport 8100 modules have the following features:
• One active and one optional standby CPU subsystem with fast fail-over in the
event of loss of one CPU
• Hardware redundancy features, including power supplies, chassis fans, and
switch management modules
• High-speed forwarding rate, up to 3 million packets per second (peak)
• Store-and-forward switching, providing full-performance forwarding at full
line speed
• Learning rate of 3 million addresses per second (peak)
• Address database capacity of up to 16,000 entries at line rate (32,000 entries
without flooding)
• Connection to a high-speed backplane for forwarding of packets between
modules
• Front-panel LEDs for monitoring port activity and module operation
• Expansion slot for installation of an optional media dependent adapter to
provide 100BASE-FX fiber connections, Gigabit Ethernet connections, or
additional 10/100BASE-TX connections (Passport 8132TX module only)
• Support for Spanning Tree Protocol with one spanning tree group in two
modes:
— IEEE 802.1D-compliant mode
— FastStart mode, which allows the port to reach forwarding state faster
Spanning tree can be disabled on individual ports or the entire switch.
