BLADEOS 6.5.2 Application Guide

Part 2: Securing the Switch

￿Chapter 3, “Securing Administration,” describes methods for using Secure Shell for administration connections, and configuring end-user access control.

￿Chapter 4, “Authentication & Authorization Protocols,” describes different secure administration for remote administrators. This includes using Remote Authentication Dial-in User Service (RADIUS), as well as TACACS+ and LDAP.

￿Chapter 5, “Access Control Lists,” describes how to use filters to permit or deny specific types of traffic, based on a variety of source, destination, and packet attributes.

Part 3: Switch Basics

￿Chapter 6, “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, and Private VLANs.

￿Chapter 7, “Ports and Trunking,” describes how to group multiple physical ports together to aggregate the bandwidth between large-scale network devices.

￿Chapter 8, “Spanning Tree Protocols,” discusses how Spanning Tree Protocol (STP) configures the network so that the switch selects the most efficient path when multiple paths exist. Also includes the Rapid Spanning Tree Protocol (RSTP), Per-VLAN Rapid Spanning Tree Plus (PVRST+), and Multiple Spanning Tree Protocol (MSTP) extensions to STP.

￿Chapter 9, “Quality of Service,” discusses Quality of Service (QoS) features, including IP filtering using Access Control Lists (ACLs), Differentiated Services, and IEEE 802.1p priority values.

Part 4: Advanced Switching Features

￿Chapter 10, “Deployment Profiles,” describes how the G8124 can operate in different modes for different deployment scenarios, adjusting switch capacity levels in order to optimize performance for different types of networks.

￿Chapter 11, “Virtualization,” provides an overview of allocating resources based on the logical needs of the data center, rather than on the strict, physical nature of components.

￿Chapter 12, “Virtual NICs,” discusses using virtual NIC (vNIC) technology to divide NICs into multiple logical, independent instances.

￿Chapter 13, “VMready,” discusses virtual machine (VM) support on the G8124.

￿Chapter 14, “FCoE and CEE,” discusses using various Converged Enhanced Ethernet (CEE) features such as Priority-based Flow Control (PFC), Enhanced Transmission Selection (ETS), and FIP Snooping for solutions such as Fibre Channel over Ethernet (FCoE).
