User manual HP 10GB ETHERNET BL-C SWITCH FOR C-CLASS BLADESYSTEM

[. . . ] HP 10Gb Ethernet BL-c Switch User Guide Part Number 445941-002 August 2008 (Second Edition) © Copyright 2007, 2008 Hewlett-Packard Development Company, L. P. The information contained herein is subject to change without notice. The only warranties for HP products and services are set forth in the express warranty statements accompanying such products and services. Nothing herein should be construed as constituting an additional warranty. [. . . ] Version 1-, Version 2-, and Version 3-based IGMP Snooping are supported. In addition, auto detection of the multicast router port and manual configuration of the multicast router port is supported. For efficient multicast traffic management, the IGMP Filtering option is supported. Jumbo frames By default, the switch supports jumbo frames up to 12 KB, which help reduce server CPU utilization and increase application throughput. The switch does not fragment frames as they exit, or assemble packets into jumbo frames as they enter the switch. XFP transceiver ports The switch supports up to four ten Gigabit uplinks by the use of XFP fiber transceivers. The ports accept only HP specific XFP transceivers and currently come in two versions: SR XFP transceivers and LR XFP transceivers. SR transceivers support data transfer to distances up to 82 meters using multimode fiber. LR XFP transceivers support data transfer to distances up to 10Km using single mode fiber. Redundant images in firmware The switch stores up to two different software images, called image1 and image2, as well as boot software, called boot. When downloading new software, the ability to specify where it is to be placed (into image1, image2, or boot) is activated. For example, if the active image is currently loaded into image1, load the new image software into image2. This allows a test of the new software and the option to revert back to the original image stored in image1, if needed. CAUTION: Unlike the firmware that has two images, there is only one image of boot supported. Upgrading the boot image replaces the original boot image.

This address is needed when configuring the switch. Planning the switch configuration The switch ships with a default configuration in which all downlink and uplink ports are enabled and assigned a default VLAN with a VID equal to 1. This default configuration simplifies the initial setup by allowing use of a single uplink cable (from any external Ethernet connector) to connect the server blade enclosure to the network. Assess the particular server environment to determine any requirements for other considerations. The switch does not affect or determine NIC numeration and the associated mapping of NIC interfaces to switch ports. The numbering of the NICs on the server (for example, NIC 1, NIC 2, NIC 3) is determined by the server type, the server operating system, and which NICs are enabled on the server. NOTE: Port 18 is reserved for connection to the Onboard Administrator module for switch management. This allows a user to enable the functionality of future firmware upgrade releases. The Onboard Administrator module controls all port enabling. Enabling is based on matching ports between the server and the interconnect bay. [. . . ] 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. · Cannot enable a port in multiple VLANs while configuring VLANS Action: A port is part of only one VLAN unless the port is a tagged port. Be sure that the port is enabled as a tagged port. Troubleshooting 51 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. [. . . ]
