Alteon OS Application Guide

What You’ll Find in This Guide

This guide will help you plan, implement, and administer Alteon OS software. Where possible, each section provides feature overviews, usage examples, and configuration instructions.

Part 1: Basic Switching

„Chapter 1, “Accessing the Switch,” describes how to access the GbE Switch Module to configure, view information and run statistics on the switch. This chapter also discusses different methods to manage the switch for remote administrators using specific IP addresses, authentication, Secure Shell (SSH), and Secure Copy (SCP).

„Chapter 2, “Port-based Network Access Control,” describes how to authenticate devices attached to a LAN port that has point-to-point connection characteristics. It prevents access to ports that fail authentication and authorization. This feature provides security to ports of the GbESM that connect to blade servers.

„Chapter 3, “VLANs,” describes how to configure Virtual Local Area Networks (VLANs) for creating separate network segments, including how to use VLAN tagging for devices that use multiple VLANs. This chapter also describes Protocol-based VLANs, Private VLANs, and Generic VLAN Registration Protocol (GVRP).

„Chapter 4, “Ports and Trunking,” describes how to group multiple physical ports together to aggregate the bandwidth between large-scale network devices.

„Chapter 5, “Spanning Tree Group,” discusses how Spanning Trees configure the network so that the switch uses the most efficient path when multiple paths exist.

„Chapter 6, “Rapid Spanning Tree Protocol/Multiple Spanning Tree Protocol,” describes Rapid Spanning Tree and Multiple Spanning Tree configurations.

„Chapter 7, “Quality of Service,” discusses Quality of Service features, including IP filter- ing using Access Control Lists, Differentiated Services, and IEEE 802.1p priority values.

Part 2: IP Routing

„Chapter 8, “Basic IP Routing,” describes how to configure the GbE Switch Module for IP routing using IP subnets, and DHCP Relay.

„Chapter 9, “Routing Information Protocol,” describes how the Alteon OS software imple- ments standard RIP for exchanging TCP/IP route information with other routers.

„Chapter 10, “IGMP,” describes how the Alteon OS software implements IGMP Snooping or IGMP Relay to handle multicast traffic efficiently.
