Introduction Integrated Administrator The ProLiant BL e-Class Integrated Administrator provides centralized, remote management and monitoring for the ProLiant BL e-Class server blade enclosure, interconnect switch module, and 20 server blades. The Integrated Administrator acts as a combination terminal server and remote power controller, enabling out-of-band, secure, serial console connections to all server blades in the enclosure.
Introduction Supported Technologies The ProLiant BL e-Class C-GbE Interconnect Switch supports the following technologies. Layer 2 Switching The ProLiant BL e-Class C-GbE Interconnect Switch uses 10/100/1000 Gigabit Layer 2 switching technology. Layer 2 refers to the Data Link layer of the Open Systems Interconnection (OSI) model, which is concerned with moving data packets across a network by enforcing Carrier Sense Multiple Access with Collision Detection (CSMA/CD).
Introduction Simple Network Management Protocol and Remote Monitoring Each switch module can be configured and monitored remotely from a Simple Network Management Protocol (SNMP)/Remote Monitoring (RMON) based Network Management Station. The switch modules support industry-standard SNMP Management Information Bases (MIBs), HP Switch MIBs, and RMON groups 1 (statistics), 2 (History), 3 (Alarm), and 9 (Event) for fault detection, configuration, and monitoring of switch functionality.
Introduction IEEE 802.1p-Based Class of Service for Packet Prioritization Class of Service (CoS) for packet prioritization allows switch administrators to set priority levels on the interconnect switch for forwarding packets based on the priority setting information in the packets. The interconnect switch supports four classes of traffic (buffers or queues) for implementing priority. The interconnect switch allows administrators to map eight priority levels to four classes.
Introduction Simple Network Time Protocol The interconnect switch can maintain the current date and time. This information displays on the management interfaces and is used to record the date and time of switch events. Current date and time information can be manually set on the interconnect swithc or can be obtained through Simple Network Time Protocol (SNTP).

Setting up and Installing the Interconnect Switch Planning the Interconnect Switch Configuration Before you configure the switch modules, HP recommends that you plan the configuration. As you plan, keep in mind the default settings, security issues and privileges, and whether you want to configure each switch module manually or configure multiple switch modules at the same time. Default Settings IMPORTANT: Refer to Appendix C for detailed default configuration settings.
Setting up and Installing the Interconnect Switch Interconnect Switch Security When planning the configuration for a switch module, secure access to the management interface by: • Creating users with various access levels to the local console, remote Telnet, and Web interface. Refer to Table 2-1 for the three levels of user access privileges. • Enabling or disabling access to various management interfaces to fit the security policy.
Setting up and Installing the Interconnect Switch Configuring Multiple Switch Modules You can configure multiple switch modules by using scripted Command Line Interface (CLI) commands through Telnet or by downloading a configuration file using a TFTP server. Using Scripted CLI Commands through Telnet The CLI, provided with the interconnect switch, allows you to execute customized configuration scripts on multiple switch modules.
Setting up and Installing the Interconnect Switch To cable the interconnect tray: Figure 2-13: Connecting the Integrated Administrator module 1. Connect the Integrated Administrator module to your network by using the management connector (10/100 Ethernet). Figure 2-14: Connecting the network cables 2. Install the network cables.

D Spanning Tree Protocol Introduction When Spanning Tree Protocol determines a port should be transitioned to the forwarding state, the following occurs: • The port is put into the listening state where it receives Bridge Protocol Data Units (BPDUs) and passes them to the GbE Interconnect Switch’s CPU. • If no BPDUs that suggest the port should go to the blocking state are received, the BPDU packets from the CPU are processed — The port waits for the expiration of the forward delay timer.
Spanning Tree Protocol • Does not transmit BPDUs received from the CPU. • Receives and responds to network management messages. Figure D-1: Blocking State Listening State The listening state is the first transition for a port from the blocking state. Listening is an opportunity for the switch to receive BPDUs that may tell the switch that the port should not continue to transition to the forwarding state, but should return to the blocking state (that is, a different port is a better choice).
Spanning Tree Protocol A port in the listening state does the following: • Discards frames received from the network segment to which it is attached. • Discards packets sent from another port on the switch for forwarding. • Does not add addresses to its forwarding database. • Receives BPDUs and directs them to the CPU. • Processes BPDUs received from the CPU. • Receives and responds to network management messages.
Spanning Tree Protocol Learning State A port in the learning state prepares to participate in frame forwarding. The port enters the learning state from the listening state. A port in the learning state does the following: D-4 • Discards frames received from the network segment to which it is attached. • Discards packets sent from another port on the switch for forwarding. • Adds addresses to its forwarding database. • Receives BPDUs and directs them to the CPU.
Spanning Tree Protocol Figure D-3: Learning State Forwarding State A port in the forwarding state forwards packets. The port enters the forwarding state from the learning state when the forward delay timer expires.
Spanning Tree Protocol A port in the forwarding state does the following: • Forwards packets received from the network segment to which it is attached. • Forwards packets sent from another port on the switch for forwarding. • Incorporates station location information into its address database. • Receives BPDUs and directs them to the system CPU. • Receives and responds to network management messages.
Spanning Tree Protocol Disabled State A port in the disabled state does not participate in frame forwarding or STP. A port in the disabled state is virtually non-operational. A disabled port does the following: • Discards packets received from the network segment to which it is attached. • Discards packets sent from another port on the switch for forwarding. • Does not add addresses to its forwarding database. • Receives BPDUs, but does not direct them to the system CPU.

Spanning Tree Protocol Troubleshooting STP This section describes several troubleshooting tips. Spanning Tree Protocol Failure A failure in the STP generally leads to a bridging loop. A bridging loop in an STP environment comes from a port that should be in the blocking state, but is forwarding packets. Figure D-6: Example of Spanning Tree Protocol failure In this example, B has been elected as the designated bridge, and Port 2 on C is in the blocking state.
Spanning Tree Protocol Full/Half Duplex Mismatch A mismatch in the duplex state of two ports is a very common configuration error for a pointto-point link. If one port is configured as full-duplex, and the other port is left in autonegotiation mode, the second port will end up in half-duplex because ports configured as half- or full-duplex do not negotiate.
Spanning Tree Protocol Unidirectional Link Unidirectional links can be caused by an undetected failure in one side of a fiber cable, or a problem with a ports transceiver. Any failure that allows a link to remain up while providing one-way communication is very dangerous for STP. Figure D-8: Example unidirectional link In this example, Port 2 on B can receive but not transmit packets.
Spanning Tree Protocol Packet Corruption Packet corruption can also lead to Spanning Tree Protocol failure. If a link is experiencing a high rate of physical errors, a large number of consecutive BPDUs can be dropped and a port in the blocking state would transition to the forwarding state. The blocking port would have to have the BPDUs are dropped for 50 seconds (at the default settings) and a single BPDU would reset the timer. If the max age is set too low, this time is reduced.
Spanning Tree Protocol Avoiding Trouble Below are some tips for avoiding trouble. Know Where the Root is Located Although the STP can elect a root bridge, a well-designed network will have an identifiable root for each VLAN. Careful setup of the STP parameters will lead to the selection of this best interconnect switch as the root for each VLAN. Redundant links can then be built into the network.
Spanning Tree Protocol The above graphic is an example of a common network design. The switches C and D have redundant links to the backbone switches A and B using trunks. Trunks, by default, carry all the VLAN traffic from VLAN 1 and VLAN 2. So switch C is not only receiving traffic for VLAN 1, but it is also receiving unnecessary broadcast and multicast traffic for VLAN 2. It is also blocking one port for VLAN 2.
E SNMP/RMON MIBs Support Introduction Management and statistics information is stored in the interconnect switch in the Management Information Base (MIB). The interconnect switch supports several standard MIBs. Values for MIB objects can be retrieved with any SNMP-based network management software. In addition to the standard MIBs, the switch also supports its own proprietary enterprise MIB as an extended Management Information Base.
SNMP/RMON MIBs Support Use an SNMP manager, such as HP OpenView or IBM Tivoli NetView, to access the enterprise-specific MIBs. Compile the MIBs into the MIB database and then use a MIB browser to navigate through them. For detailed information, access the individual descriptions of each MIB or refer to the documentation that came with your SNMP manager software.

G Port Trunking and Load Balancing in Blade Switches Introduction IEEE 802.3ad and EtherChannel compatible port trunks allow multiple physical Ethernet links to be combined into one logical channel/trunk. This allows load sharing of traffic among the links in the port trunk as well as redundancy in the event that one or more links in the port trunk should fail.
Port Trunking and Load Balancing in Blade Switches Circumstances can occur where one address in the source/destination pair is a constant. For example, the destination might be a server or, even more likely, a router. In that case, if both the source address and destination address option is selected, you will still see statistical load balancing, because the source address is always different.
Port Trunking and Load Balancing in Blade Switches Configuring Load Balancing on Blade Switches To configure the load balancing and forwarding method using the menu-driven interface, access the Configure Advanced Switch Features screen. Toggle the Trunk Load Sharing Algorithm field to the appropriate selection. To configure the load balancing and forwarding method using the Web-based interface, access the Switch Information (Advanced Settings) screen.
Port Trunking and Load Balancing in Blade Switches Hashing Algorithms for Load Balancing The hashing algorithms use the last three least significant bits (LSB) of the destination MAC address (DA), source MAC address (SA), or destination and source MAC address (DA XOR SA) and the number of links that are available to forward frames in that port trunk group as operators.
Port Trunking and Load Balancing in Blade Switches For example: There is a port trunk group with eight member ports, and there is a frame with SA=0x0080C800000B DA=0x0080C800000C. • SA last three bits is 0b011 • DA last three bits is 0b100 • SA XOR DA is 0b111 In the following example, four trunk ports are link up in the port trunk. • For algorithm 1, N = 0b011 MOD 4 = 3 The outgoing port would be the fourth link up in the port trunk.
Port Trunking and Load Balancing in Blade Switches Redundancy: What Happens When One Link in the Port Trunk Fails? If a segment within the port trunk fails, traffic previously carried over the failed link switches to the remaining segments within the port trunk. Inbound broadcast and multicast packets on one segment in a port trunk are blocked from returning on any other segment of the port trunk. 802.
H XML Configuration Introduction Beginning in firmware version 2.0.0, interconnect switch firmware configuration files are specified in eXtensible Markup Language (XML) format. In previous versions, the configuration file was stored in binary format. Binary configuration files saved from previous versions cannot be downloaded into firmware version 2.0.0. However, previous configuration settings are preserved during the firmware upgrade to version 2.0.0.
XML Configuration Safe Mode When inserting a new or replacement interconnect switch into a production environment, you must be certain that the interconnect switch configuration is compatible with the production network. Compatibility with a network can include items such as: • Non-corruption of the network in general—Corruption, such as loops, can occur within the network without enabling Spanning Tree Protocol (STP).
XML Configuration Safe Mode Configuration File Templates Two example template configuration files have been provided as a basis to create an appropriate safe mode configuration. Each file is delivered with the Switch Management Utilities package specific to a particular type of interconnect switch. • esafe_ex.xml • psafe_ex.xml NOTE: The templates provided are only examples, and should not be used in a production environment without modifications rquired for your specific production network.
XML Configuration • Change the following settings to match the remote TFTP server. • Port 19 has been left Enabled on p-Class interconnect switches (port 23 on e-Class).
XML Configuration • You may wish to allow only a single IP address (management station) access. • Change the read-write community string per your environment.
