Overview of the Model 5625HD Switch Module

Features of the Model 5625HD Switch Module

The Model 5625HD switch module off ers the following feature s:

• 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

206208-A

Protocol-sensitive VLANs classifies packets based on protocol types. Most customers have multiple protocols per LAN segment , so a swit ch port needs to support multiple VLANs based on different protocol type s. This feature allows you to separa te data base d on pro tocols and not on ph ysica l limit ations.

• IEEE 802.1Q Ta g Recognition Support The Model 5625HD switch module supports recog nition 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 fra me 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

• Support for RMON Management Information Base (MIB)

– Ethernet Statistics Group – Ethernet History Group – Ethernet Alarm Group – Ethernet Event Group

• Ability to install, remove, and replace a module in an operational chassi s (hot-swap)

• Hardware Assist Multi-Protocol over ATM (MPOA) MPOA is the ATM Forum standard that specifies a method to efficiently

transport intersubnet unicast data in a LANE environment. MPOA uses LANE and NHRP processes to allow dire ct shortcut virtual channel connections (VCCs) to be established for inter subnet communication without requiring pass age through a router. The intrasubnet communication continues to be supported over LANE. For IP, Nortel Networks has adopted MPOA as the standard to implement layer 3 switching in an ATM network.

• Improved performance in segmentation and reassembly (SAR) to 3.2 gigabit

• Multi-Link Trunking (MLT)

Using the Model 5625HD EtherSpeed Switch Module

There are 2 4 RJ-45 ports on the Model 5625HD switch module that automatically detect speed and duplex mode. (For more information a bout cables, refer to

Appendix B, “

Cables and Connectors.”)

Each Model 5625HD switch module oc cupies one slot in a Model 500x BH/BHC chassis. You can install a maximum of 10 Model 5625HD switch modules, along with two master control processor (MCP) switch modules, in a Model 5000BH/ BHC chassis or a maximum of five Model 5625HD switch modules, and one MCP switch module, in a Model 5005BH chassis.

Switch Configuration and Management

You manage and configure a Model 5625HD switch module through access to an installed MCP module in the Model 500xBH/BHC chassis with the following network management features:

• SpeedView for Windows 4.1 and greater

• Command line interface (CLI)

• Simple Network Management Protocol (SNMP) agent with Sy stem 5000 MIB extensions

• Trivial Fi le Transfer Protoc ol ( TFTP) support

SpeedView

SpeedView is a network management application that runs on Microsoft Windows® 95 or Windows 98 and Windows NT® and provides a graphical user interface to set up your switch. SpeedView allows you to monitor and control network traffic and to perform advanced operations such as filter configuration. For more information about SpeedView, refer to Using SpeedView 4.0 for W indows and Release Notes for Spe edView 4.1.
