HP ProCurve: Loop-Protect at 2848 and 3400cl-48G

Yay, there is support for the loop-protect feature at the backbones (3400cl-48G) and the client switches (2848). It’s supported within firmware release I.10.22 at both ones. Now I look forward to update the firmware on the switches again.

Found this in the Release Notes of the Switches:

Configuring Loop Protection You can use BPDU protection for systems that have spanning tree enabled (See “Spanning Tree BPDU Protection” on page 57), however, the BPDU protection feature cannot detect the formation of loops when an unmanaged device on the network drops spanning tree packets. To protect against the formation of loops in these cases, you can enable the Loop Protection feature, which provides protection by transmitting loop protocol packets out ports on which loop protection has been enabled. When the switch sends out a loop protocol packet and then receives the same packet on a port that has send-disable configured, it shuts down the port from which the packet was sent. You can configure the disable-timer parameter for the amount of time you want the port to remain disabled (0 to 604800 seconds). If you configure a value of zero, the port will not be re-enabled.

The config options etc. are same like I posted yesterday.
