Introduction In this section Overview ................................................................................................................................................ 6 Additional references................................................................................................................................ 6 Features ..................................................................................................................................................
• Fully supported on the HP c-Class BladeSystem server blade enclosure and infrastructure compatible with any combination of HP c-Class BladeSystem server blades • Ability to replace an existing switch without having to power down the server blades or the server blade enclosure • Pre-configured for immediate use with the HP c-Class BladeSystem server blade enclosure • System security including SSH, SCP, 255 port-based IEEE 802.
• Port Fast Forwarding that allows a port that participates in Spanning Tree to bypass the Listening and Learning states and enter directly into the Forwarding state. • Allows secure browser access (HTTPS) to management functions Switch redundancy In a dual switch configuration, the switches offer several redundancy and failover features. With these features, the network configuration is designed to allow for continued network access to each server blade in case of a component or link failure.
• Any switch port can be used to perform switch management and PXE.
Redundant paths to server bays In a dual switch configuration, redundant Ethernet signals from each blade server are routed through the enclosure backplane to separate switches within the enclosure. This configuration provides redundant paths to each server bay. Redundant Ethernet signals from each blade server are routed through the enclosure backplane to separate switches within the enclosure. However, specific switch port to server mapping varies depending on which type of server blade is installed.
In addition, the switch provides a spanning tree domain per VLAN. The switch is compatible with Cisco® PVST+ and Cisco PVST, when the other device is configured as untagged or configured to use 802.1q tagging. Sixteen spanning tree domains are supported per switch. NOTE: STP 16 is reserved for future functionality. The switch also provides IEEE 802.1s-based MSTP and IEEE 802.1w-based RSTP. SNMP The switch is configured and monitored remotely from an SNMP-based network management station.
configurable from the browser-based interface, but because the connection is based on an IP address for these interfaces, users will have to reconnect with the newly assigned IP address. NTP The switch maintains 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 are manually set on the switch or are obtained through NTP.
• 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 user, oper, and admin, respectively. • The accounting attributes of protocol, start_time, stop_time, and elapsed_time. For BBI users, accounting stop records are only sent if the user presses the QUIT button.
through a procedure called auto-negotiation. Auto-negotiation involves probing the capability of the network using low-level signaling techniques to select compatible Ethernet speeds. Auto-negotiation was originally developed to make the migration from traditional Ethernet to Fast Ethernet products easier. Redundant images in firmware The switch stores up to two different software images, called image1 and image2, as well as boot software, called boot.
Item Description 4 DB-9 management serial port 5 RJ-45 ports 20 - 24 Description CAUTION: Pressing the Reset button while the Health LED is green resets the switch.

• SNMP settings • User name and password settings • Default access to various management interfaces • NTP settings IMPORTANT: See "Runtime switching software default settings (on page 28)" for a complete list of default configuration settings.
User account Description and tasks performed Operator The operator manages all functions of the switch. The operator can reset ports or the entire switch. Password By default, the operator account is disabled and has no password. Administrator The super user administrator has complete access to all menus, information, and configuration commands on the switch, including the ability to change both the user and administrator passwords.
Installing the switch CAUTION: Do not cable the switch until after configuration. IMPORTANT: Make sure that the server NIC configuration matches the switch bay selected. NOTE: When installing two switches, there are two switch interconnect ports between adjacent I/O bays. These ports (17 and 18) are disabled by default. The ports must be manually enabled to use. To install the switch: 1. Remove the blank. 2. Install the switch.
To access the switch remotely: 1. Assign an IP address. By default, the switch is set up to obtain its IP address from a BOOTP server existing on the attached network. 2. From the BOOTP server, use the switch MAC address to obtain the switch IP address. 3. From a computer connected to the same network, use the IP address to access the switch using a Web browser or telnet application, which enables access to the switch BBI or CLI. The switch logon prompt appears.
See "SNMP MIBs support (on page 42)" for more information on the SNMP agents. This section also describes how to use the MIBs to configure and monitor the switch using a generic SNMP manager, such as HP OpenView Network Node Manager or HP Systems Insight Manager. Cabling the switch CAUTION: Do not cable the switch until after configuration. To connect the switch to the network: 1. Connect the network cables to the switch. 2. Gather the network cables for the right side of the rack. 3.
Replacing and upgrading the switch In this section Replacing an existing switch.................................................................................................................... 22 Replacing an existing switch CAUTION: Removing the switch from a powered enclosure results in the loss of network communications between the server blade network ports that are connected through this switch and the segment of network infrastructure those ports need to communicate.
5. If the configuration file was saved to a TFTP server, download the configuration. For more information on downloading a configuration file, see the HP GbE2c Ethernet Blade Switch for cClass BladeSystem Command Reference Guide.
