HP J3250M manual Spanning Tree Protocol, Forward with High Priority

Managing Switches

Configuration

Note: Using the console you can designate specific ports to always or never forward multicast packets.

Forward with High Priority

When “Forward with High Priority” is checked, any IGMP packets received by the switch will be forwarded in a prioritized manner, preceding packets with normal priority.

The Spanning Tree Protocol

The Spanning Tree Protocol (IEEE 802.1d) maintains a loop-free topology in networks with redundant bridges or switches. The spanning tree devices determine which devices will be active and which will be backups so that no two nodes in a network have more than one active path between them at any time. The Spanning Tree Protocol uses the most efficient path between segments. If a bridge or switch fails, the other bridges and switches reconfigure the network automatically. When the problem is repaired, the bridges and switches automatically return to the original network configuration.
