© 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. [. . . ] If not, the receiving computer sends a request for retransmission of the data.
IGMP Snooping
The switch supports IGMP Snooping for multicasting. 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 9216 bytes, 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.
Auto-MDI/MDIX
The switch RJ-45 Ethernet ports are MDI/MDI crossover capable. MDI/MDIX is a type of Ethernet port connection using twisted pair cabling. The MDI is the component of the MAU that provides the physical and electrical connection to the cabling medium. An MDIX is a version of MDI that enables connection between like devices. MDI ports connect to MDIX ports via straight-through twisted pair cabling whereas both MDI-to-MDI and MDIX-to-MDIX connections use crossover twisted pair cabling. The switch has the capability to automatically detect the cable selection/type, making the distinction between a straightthrough cable and a crossover cable unimportant.
Auto-negotiation of duplex mode and speed on 1 Gigabit ports
Auto-negotiation of duplex mode and speed are configured on the switch. Network adapters that support multiple data speeds, such as Fast Ethernet and Gigabit Ethernet, choose the speed at which they run 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.
Introduction

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.

Installing the switch
Preparing for installation
IMPORTANT: Before installing the switch, make a record of the MAC address (printed on the MAC address label attached to the switch). 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. [. . . ] From the serial console interface, be sure that the management network address/mask contains the IP address of the management station.

Troubleshooting 56
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.
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.
While using TFTP to download firmware, the switch fails to connect to the TFTP server, or after connection the download fails
Action:
·
The TFTP server is not available to connect to or there is connectivity failure between the switch and TFTP server.
o o o
Be sure that the IP address of the TFTP server is correct. [. . . ]
