CrossFire 8730 Switch Installation Guide, DOC-7046 v. 1.2 Introduction
Features
Performance and Advanced Features
•
High-speed translation between Token-Ring and Fast Ethernet
•
Dedicated Translation Processors
— Four Field Programmable Gate Arrays (FPGA) and two RISC processors
are dedicated to the process of translating between Token-Ring and Fast
Ethernet. This ensures the high-speed, low-latency performance needed to
avoid creating a bottleneck at Fast Ethernet ports.
•
Three switching modes:
— Low latency cut-through mode for the Token-Ring ports
— Store and Forward mode for both Token-Ring and Fast Ethernet ports
— Auto (adaptive cut-through) for the Token-Ring ports
•
Enhanced bridging modes:
— Transparent Bridging
— Source Route Switching
— Source Route Bridging (SRB)
— Source Route Transparent Bridging (SRT)
•
Support for duplicate MAC address schemes
•
Automatic port sensing of operating mode and media speed
•
Multiple Token-Ring port operation modes:
— Half-duplex concentrator and station
— Full-duplex concentrator and station (DTR, Dedicated Token-Ring)
— RI/RO-like connection
•
Fast Ethernet port operation modes
— Half-duplex, 10 or 100 Mbps
— Full-duplex, 10 or 100 Mbps
•
Spanning tree protocol (STP) support:
— IEEE 802.1D for all ports
— IBM Spanning Tree Protocol for the Token-Ring ports
