Igmp Snooping; Jumbo Frames; Xfp Transceiver Ports; Redundant Images In Firmware - HP 445860-B21 - 10Gb Ethernet BL-c Switch User Manual

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 12 KB, which help reduce server CPU utilization and
increase application throughput. No configuration is required. 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:
supported. Upgrading the boot image replaces the original boot image.
Unlike the firmware that has two images, there is only one image of boot
