Spanning Tree Protocol

In networks with multiple switches and bridges, there can be multiple physical connections between two connected network participants. These redundant data paths are desirable, as they provide alternative routes to the destination if individual network segments fail. On the other hand, these multiple connections can lead to undesirable loops or duplicate frame reception. Both effects disrupt the smooth flow of data in the network.

In particular, when using LANCOM LX-7500 access points for hitless failover, the use of the (Rapid) Spanning Tree Protocol ((R)STP) is essential to ensure redundancy not only in power supply but also in data transmission and to prevent the formation of a loop.

Note: Alternatively, LACP can also be used in conjunction with hitless failover. Depending on the access point model, link speed and switching speed should be considered.

Note: By default, RSTP is enabled on the LANCOM LX-7500 to allow out-of-the-box operation with both Ethernet connections. In general, the Spanning Tree Protocol is supported by all access points with at least two Ethernet ports.
