  • Page 43: Chapter 5. Nortel Networks L2/3 Gbesm Management And Administration

    In this chapter, we discuss tools, techniques, and applications that help with the management and deployment of the Nortel GbESM in an IBM Eserver BladeCenter. We also discuss the management paths and rules for connecting to and accessing the Nortel GbESM.

  • Page 44: Nortel Networks L2/3 Gbesm Management Connectivity

    In this section, we look at the basic management connectivity and management pathways to the Nortel GbESM., as shown in Figure 5-1. Important: Properly managing the Nortel GbESM in the IBM Eserver BladeCenter actually requires proper management of the Management Module within the BladeCenter chassis.

  • Page 45: Out-Of-Band Management

    Management Module supports an external Ethernet interface, which is used to manage the Blade servers, Ethernet switches, and the Management Module itself. Within the IBM Eserver BladeCenter, management traffic flows through a different bus, the I2C bus, as shown in the Figure 5-1 on page 30.

  • Page 46: In-Band Management

    Further configuration of the Nortel Networks L2/3 GbESM module is performed by using Telnet (for the Command Line Interface) or a Web browser (for the Browser Based Interface) and accessing the address of the MGT1 or 2 ports. Note: It is recommended (and easier) to use a server or mobile computer that is external to the IBM Eserver BladeCenter chassis to perform initial configuration of the Nortel Networks L2/3 GbESM module.
  • Page 47 In order to use in-band management paths, you must configure at least one additional IP address on the Nortel Networks L2/3 GbESM beyond the address that is provided through the Management Module and attached to VLAN 4095. This additional IP address should be attached to one of the active VLANs configured on the switch and is discussed in detail in 7.5.3, “Base configuration common to all examples”...

    Configuring user accounts This section describes the user accounts on the switch.

When accessing the CLI in this mode, there is only a single prompt to enter the password.

    5.2.3 Browser Based Interface We now take a brief look at the Browser-Based Interface (BBI) on the Nortel Networks L2/3 GbESM. Almost everything that can be done via the CLI can also be done in the BBI. In the remainder of this book, more emphasis is placed on configuring the switch using the CLI rather than using the BBI.

    Otherwise, you must use a router. Use the Management Module graphical interface to configure the IP addresses of the Management Module external network interface (eth0) and the Nortel Networks L2/3 GbESM so that they are on the same subnet as the TFTP server. Note: Alternatively, you can use FTP instead of TFTP.

    In most cases, you should configure trunk failover on all Nortel Networks L2/3 GbESM in the IBM Eserver BladeCenter if the server blades are running NIC Teaming. These two features work together to provide a High Availability design.

  • Page 77: Introduction To Nic Teaming

    In the IBM Eserver BladeCenter, NIC teaming will detect the failure of a NIC chip on the server blade, the loss of connection to a switch module via the midplane, and the failure of a switch module (including intentional removal or power-off).

  • Page 79: Some Important Rules For Ensuring High Availability

    Based on this, we strongly recommend that you use a cross-over cable between the Nortel Networks L2/3 GbESMs and upstream switches. This helps ensure that the link always works under all possible conditions.

    The fiber connectors on the Nortel Networks Layer 2/3 Fiber Gigabit Ethernet Switch Module for IBM Eserver BladeCenter must be Multi-Mode Fiber (MMF). Either 50 or 62.5 micron fiber can be used. Single-Mode (9 micron) fiber is not supported. The fiber should be terminated with LC connectors on both ends.

    The GbESM interoperates with Cisco Per VLAN Spanning Tree (PVST) protocol using up to 16 Spanning Tree groups. This section shows how to configure separate Spanning Tree Groups (STG) for each VLAN using Cisco’s proprietary PVST and IEEE 802.1D (Common/Mono Spanning Tree).

    Ethernet interface(s) for administration (SSH for example). If BOOTP is needed for JS20, again, the second network interface is recommended. There are no specific rules that apply to the Nortel Networks L2/3 GbESM itself. The switch by default reserves VLAN 4095 for SOL traffic.

    As long as the SOL VLAN ID value in the Management Module Web interface is set to 4095, there are no other specific configuration steps for the Nortel Networks L2/3 GbESM, because the Nortel Networks L2/3 GbESM reserves VLAN 4095 for SOL. All other configuration steps involve either the Management Module or the blade server.

    9.2.1 General comments on troubleshooting Because of the highly integrated nature of the Nortel Networks L2/3 GbESM within the IBM Eserver BladeCenter, it is usually necessary to engage several teams for anything beyond basic hardware troubleshooting. Experience has shown that the greater the communication between administrative groups, the more likely an issue can be resolved sooner rather than later.

    9.3.2 Data collection In this particular step, it might be necessary to collect additional information to help isolate problem cause as noted in the following sections. Test connectivity Use connectivity testing tools such as ping, traceroute, and Telnet Note error messages that appear Details from affected users Ask more detailed questions: Has anything changed recently?

  • Page 174: Data Analysis

    Ensure that your changes have not inadvertently caused other problems. If another problem is created, try to troubleshoot that problem (if you have time and approval). Otherwise, initiate the back-out plan. Nortel Networks L2/3 Ethernet Switch Module for IBM Eserver BladeCenter...
