Figure 2 HP ProLiant BL p-Class GbE2 Interconnect Switch and QuadSX Interconnect Module Features The ProLiant BL p-Class GbE2 Interconnect Switch and interconnect modules are designed for easy installation and high performance in an environment where traffic on the network and the number of users increases continually. Enterprise class performance The ProLiant BL p-Class GbE2 Interconnect Switch features include: • Up to a 16-to-1 reduction in networking cables and connections, concent

• Remote Monitoring (RMON) feature, which allows network devices to exchange network monitoring data. RMON performs the following major functions: • Gathers cumulative statistics for Ethernet interfaces • Tracks a history of statistics for Ethernet interfaces • Creates and triggers alarms for user-defined events • Quality of Service (QoS) feature, where the switch uses the Differentiated Services (RFCs 2474 and 2475) architecture to provide QoS functions. QoS allocates guaranteed bandwidt

GbE2 Interconnect Switch redundancy The ProLiant BL p-Class GbE2 Interconnect Switch offers several redundancy and failover features. With these features, the network configuration can be designed to allow for continued network access to each server blade in case of a component or link failure. GbE2 Interconnect Switch redundancy and failover features include: • Two separate GbE2 Interconnect Switches per one ProLiant BL p-Class server blade enclosure • Four Gigabit Ethernet uplink ports

HP Ethernet Connectivity Mapper utility (hpecm) The HP Ethernet Connectivity Mapper is a utility used to determine the NIC name enumeration and the associated mapping to switch ports. The physical connections between server blade network interface controllers (NICs) and switch ports depend on the server blade type and the enclosure backplane type, as described above. The logical NIC name enumeration depends on the operating system software (such as Local Area Connection, Local Area Connec

Layer 2 switching technology allows the GbE2 Interconnect Switch to look into data packets and redirect them based on the destination MAC address. This reduces traffic congestion on the network because packets, instead of being transmitted to all ports, are transmitted to the destination port only. IEEE 802.1Q-based Virtual Local Area Network The ProLiant BL p-Class GbE2 Interconnect Switch provides support for a total of 255 IEEE 802.1Q Virtual Local Area Networks (VLANs) for server groupi

Interconnect Switch can also be uploaded to a TFTP server, a configuration file can be downloaded into a GbE2 Interconnect Switch from a TFTP server, and configuration settings can be saved to the TFTP server. Store and forward switching scheme The GbE2 Interconnect Switch provides a store and forward switching scheme that allows each packet to be buffered (stored) before it is forwarded to its destination. While this method creates latency, it improves reliability in a heavily used inter

authenticated using a shared key that is not sent over the network. In addition, the remote administrator passwords are sent encrypted between the TACACS+ client (the switch) and the back-end TACACS+ server. The GbE2 Interconnect Switch supports: • Only standard ASCII inbound login authentication. PAP, CHAP, or ARAP login methods are not supported. One- time password authentication is also not supported. • Authorization privilege levels of only 0, 3, and 6. These map to management levels of

Redundant images in firmware The GbE2 Interconnect Switch can store up to two different software images, called image1 and image2, as well as boot software, called boot. When you download new software, you are given the ability to specify where it is to be placed: either into image1, image2, or boot. For example, if your active image is currently loaded into image1, you should probably load the new image software into image2. This lets you test the new software and revert back to the orig
