1. INTRODUCTION
The Metro-Switch family of embedded Gigabit Ethernet switches are a high-
performance, flexible and cost-effective solution for adding scalable Gigabit Ethernet
switching capabilities for use in standalone or rackmount embedded systems
applications.
The Models 8260 and 8261 support 12-ports of 10/100/1000 Base T over copper or 10-
ports copper and 2 ports of 1000 Base X over optical fiber. The Model 8260 is a L2+ or
L3 switch utilizing lower cost switch L2+ and L3 switch devices from Broadcom. The
Model 8261 uses higher end multi-layer (L2 – L7) switch devices also in the Broadcom
StrataXGS family. Both models provide an extensive list of features including an
onboard management processor with extensible value-added firmware making it ideal
for use in many embedded systems applications.
1.1 CAPABILITIES OVERVIEW
The Metro-Switch models feature 12 ports of 10/100/1000 Base T Gigabit Ethernet over
Copper with two 1000 Base SX/LX fiber uplinks. It is PICMG 2.16 6U fabric card
compliant and compatible with both standard CompactPCI® and PICMG 2.16
backplanes. All 12-ports may be routed to slots on the Compact PCI backplane or
externally via rear I/O. A system management interface is also supported via the
PICMG 2.9 IPMI interface. It optionally supports two 1000 base SX/LX gigabit fiber
ports with standard SFF LC connectors via the front panel. It has an onboard RISC/DSP
processor for local management and can be operated as a standalone or fully managed
switch. LEDS are provided for each port showing link status, transmit and receive and
link quality. All LEDS are multifunction and can be used for additional functions
including cable testing and energy detection. It is also PICMG 2.1 R2.0 hot-swap
compliant providing support for the hardware connection layer.
The Metro-Switch models use the latest advanced high-performance, full-featured and
highly integrated 12-port Broadcom StrataSwitch BCM56XX L2+, L3 or multilayer
switches and BCM5464SR quad-port transceivers and are fully 802.3 compliant. They
provide a fully non-blocking 24Gb/32 million frames per second aggregate switching
fabric. The switching function supports an extended list of features including layer 3
switching, link aggregation, 802.1Q VLANs, 802.1D spanning tree and priority-based
802.1D/802.1p CoS/traffic class expediting and dynamic multicast filtering. The switch
can be configured in a fully redundant, non-blocking network that prevents single points
of failure from congesting network traffic. It provides advanced cell and packet based
“head of line” blocking prevention techniques, has 1MB of onboard memory for packet
buffering, and supports a 10-gig uplink interface. Extended ethernet frame sizes to 9KB
are supported. Additional advanced features including rules-based layer 2-7 packet
classification/filtering on 128 multiple data flows, port trunking and port mirroring are
provided for advanced networking and flow techniques. Network management support
