• 9K jumbo frames that improve performance by increasing application throughput and decreasing server processor utilization • Robust configuration and management from any switch port using the included browser-based and scriptable command line user interfaces.
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.
• A text-based, human read/write configuration file provides viewing, printing, and editing capabilities. • A DNS client supports primary and secondary DNS servers. • Any port can be enabled or disabled as desired. • Any switch port can be used to perform switch management and PXE.
ten Gigabit external Ethernet ports and sixteen internal Gigabit Ethernet ports providing connectivity to the blade servers within the enclosure. Redundant crosslinks In a dual switch configuration, the two switches are connected through a single ten gigabit crosslink. This crosslink provides throughput of ten Gb/s for traffic between the switches. This crosslink is disabled by default. This crosslink must be enabled for use.
• High availability VRRP Layer 3 switching provides more power, flexibility, and security capabilities to network administrators. Network traffic is managed much more efficiently and broadcast traffic between servers remains within the enclosure. Security features provide added protection for switch configuration data, while packet filtering helps secure and segment sensitive traffic or network access. IEEE 802.1 Q-based VLAN The switch provides support for a total of 1000 IEEE 802.
are members of a specific IP network. This is achieved by configuring the address/mask of that specific network as a restricted management network address/mask. Port mirroring The switch allows mirroring of one or multiple ports (source ports) to another port (destination port) for network monitoring and troubleshooting purposes.
RADIUS The switch supports the RADIUS method to authenticate and authorize remote administrators for managing the switch. This method is based on a client/server model. The RAS, the switch, is a client to the back-end database server. A remote user (the remote administrator) interacts only with the RAS, not the back-end server and database.
• 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. SSH and SCP SSH and SCP use secure tunnels to encrypt and secure messages between a remote administrator and the switch. Telnet does not provide this level of security. The Telnet method of managing a switch does not provide a secure connection.
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.

• Switch IP settings • VLAN settings • XFP settings • Port names and types • Port trunking settings • Interswitch X-Connect port settings • SNMP settings • User name and password settings • Default access to various management interfaces • NTP settings IMPORTANT: See "Runtime switching software default settings (on page 33)" for a complete list of default configuration settings.
NOTE: It is recommended to change the default switch passwords after initial configuration and as regularly as required under the network security policies. For more information, see the HP 1:10Gb Ethernet BL-c Switch Command Reference Guide. The default user name and password for each access level are: User account Description and tasks performed Password User The user has no direct responsibility for switch management.
Switch IP addresses are acquired by default using BOOTP, therefore, each switch has a unique IP address. Each switch is remotely accessed from a central deployment server and an individual switch configuration is downloaded to meet specific network requirements. See the HP 1:10Gb Ethernet BL-c Switch Command Reference Guide for additional information on using a TFTP server to upload and download configuration files. Installing the switch CAUTION: Do not cable the switch until after configuration.
A successful installation is indicated by a green Health LED. If the Health LED is amber or power is not applied to the switch, see the "Troubleshooting" section of the HP BladeSystem enclosure setup and installation guide for more information. Accessing the switch The switch is accessed remotely using the Ethernet ports or locally using the DB-9 management serial port. To access the switch remotely: 1. Assign an IP address.
NOTE: If the switch does not obtain the IP address by means of the BOOTP service, access the switch locally and configure the IP address manually. After assigning the IP address to the switch, then access the switch remotely. To access the switch locally: 1. Connect the switch DB-9 serial connector, using a null-modem serial cable to a local client device (such as a laptop computer) with VT100 terminal emulation software. 2.
Installing XFP transceivers CAUTION: To prevent damage to the fiber optic cable or the XFP transceiver, do not install or remove fiber-optic XFP transceivers with cables attached. Disconnect all cables from the XFP transceiver before removing or installing an XFP transceiver. CAUTION: Removing and installing an XFP transceiver can shorten the useful life. Do not remove and insert XFP transceivers more often than is necessary.
• Firmware Upgrade Smart Component (for Microsoft Windows only)—Provides quick and easy installation of the switch firmware, firmware upgrade tool, and readme file. A SoftPaq is available for use with Linux operating systems. The utilities package and documentation, and the SoftPaq listed above, are available on the HP website (http://www.hp.com/go/bladesystem/documentation).
Replacing a switch In this section Replacing an existing switch.................................................................................................................... 26 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. Close the ejector lever and wait for the switch boot up completely. 6. If the configuration file was saved to a TFTP server, download the configuration. For more information on downloading a configuration file, see the HP 1:10Gb Ethernet BL-c Switch Command Reference Guide.

Troubleshooting In this section Forgotten administrator user name and password that was configured on the switch ...................................... 54 Health LED on the switch is not on ............................................................................................................ 54 Health LED on the switch stays amber for more than 30 seconds and switch does not boot .............................
• The server blade enclosure is not powered up. Be sure that the server blade enclosure is powered up and all the power connections are intact. • There is a faulty LED. Check the console to see if the switch is booted. • The switch fuse is blown. Send for repair. Health LED on the switch stays amber for more than 30 seconds and switch does not boot Action: The Standby Mode Timeout function is malfunctioning. Force the switch to reboot by pressing the Reset button.
Error message that the switch failed to complete the system self-testing appears on the serial console screen Action: The system diagnostic tests failed. Note the reason for the failure from the serial console screen message and call a service representative. The switch fails to get its IP settings from the BOOTP server, even though by default it is configured for BOOTP Action: • The switch is not connected properly to the network.
• The setting allowing access to the switch using the Telnet interface is disabled. From the serial console interface, be sure that the Telnet interface is enabled. • The management network address/mask (if used) does not contain the IP address of the management station. From the serial console interface, be sure that the Management Network Address/Mask contains the IP address of the management station.
The port activity LEDs continuously indicate activity after connecting more than one port to another switch or destination device Action: Because there are multiple links across this device and the destination device, they form loops, which cause broadcast storms. Enable STP for multiple links. This setting prevents loops and maintains standby links for resilience in case of primary link failure.
The switch does not let the user enable two adjacent ports into two different VLANs while assigning the ports to VLANs Action: The ports are two adjacent ports that are bundled in a Port Trunk. Two ports that are assigned to a Port Trunk cannot be assigned to two different VLANs. Either break the trunk to assign it two different VLANs or assign the ports to one VLAN.
• o Be sure that a valid configuration file exists on the TFTP server to download to the switch. o On the switch, check the file name configured to download or upload. The TFTP server was started with a configured directory. The switch must be configured using the full path name, if it is not in the directory specified in the TFTP server.
