1. 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 Da PA 1E AP HBA EF Fia umr brih HEH ee P PSAE PIER Pr ArH E EE HRE 3 P EROH HEEE Si ee E i aT SEE EE ETE E DS SD SRL ALE E AHAS M i e E A S ja Fikih Beka D Oh fi Bae iT g e RM GC g i a BE wasa o E iim ahr e rhit ig i eE hh h aE e a H Figure 7 6 Switch Device Features ABC IGMP and STP 7 15 Syms Hu Heuen Managing Switches Managing Switches Configuration If you have configured VLANs for the switch you must do this with the device console select a VLAN for which the features will apply Configuration Support Mgmt URLs Support URL To go directly to the HP Support Site on the World Wide Web click on the Support tab You will launch the site indicated by the URL that has been entered in the Configure Support M gmt URLs page By default this is the HP Network City support site The Network City
