Enhancements

Release M.10.07 Enhancements

Release M.10.07 includes the following enhancement:

■ Added support for PIM Dense Mode. For details, refer to Chapter 5, “PIM-DM (Dense Mode)

on the 5300xl Switches” in the Advanced Traffic Management Guide for the ProCurve Series

6400cl/5300xl/4200vl/3400cl Switches.

Release M.10.08 Enhancements

Software fixes only, no new enhancements.

Release M.10.09 Enhancements

Release M.10.09 includes the following enhancement:

■ Added support for Unidirectional Link Detection (UDLD). See “Uni-Directional Link Detec-

tion (UDLD)” on page 80 for details.

Uni-Directional Link Detection (UDLD)

Uni-directional Link Detection (UDLD) monitors a link between two ProCurve switches and blocks

the ports on both ends of the link if the link fails at any point between the two devices. This feature

is particularly useful for detecting failures in fiber links and trunks.

In the example shown in Figure 20, each ProCurve switch load balances traffic across two ports in

a trunk group. Without the UDLD feature, a link failure on a link that is not directly attached to one

of the ProCurve switches remains undetected. As a result, each switch continues to send traffic on

the ports connected to the failed link. When UDLD is enabled on the trunk ports on each ProCurve

switch, the switches detect the failed link, block the ports connected to the failed link, and use the

remaining ports in the trunk group to forward the traffic.
