Overview of the Model 5625HD Switch Module
206208-A 1-3
The Model 5625HD switch module offers the following features:
• Wire-speed, port-to-port, packet transfer
• Single-slot design to fit into the System 500xBH/BHC chassis
• Autonegotiation of Ethernet 10/100 Mb/s speed
• Autonegotiation of half- or full-duplex mode on dedicated switch ports
• Layer 2 MAC-based switching
• Local frame switching, module-to-module switching, backplane switching,
and riser switching
• 200 MHz RISC processor
• 24 RJ-45 UTP network interface connectors
• Front-panel LEDs to indicate module and port operational status
• Port-based virtual LANs (VLANs)
• Protocol-based VLANs
Protocol-sensitive VLANs classifies packets based on protocol types. Most
customers have multiple protocols per LAN segment, so a switch port needs
to support multiple VLANs based on different protocol types. This feature
allows you to separate data based on protocols and not on ph ysical li mit ations.
• IEEE 802.1Q Tag Recognition Support
The Model 5625HD switch module supports recognition of VLAN tagged
frames based on IEEE 802.1Q tags. Frames entering a Model 5625HD switch
module port that contain an 802.1Q tag are mapped to a corresponding
VLAN. Based on the final destination, the frame is sent as either an
Ethernet-type frame or an 802.1Q VLAN tagged frame. VLAN membership
is to be assigned by any combination of port with either tag or protocol.
• Support for IEEE 802.1d Spanning Tree
• Content-addressable memory (CAM) support for 8192 entries
• Port steering/port mirroring
• Input and output filtering supported by switching software
• Hardware support for IP multicast
