N o t e In the factory default configuration, the Spanning Tree Protocol (STP—which
automatically blocks redundant links) is disabled. Generally, you should
enable STP to prevent broadcast storms if there are redundant links in your
network that are not part of a switch mesh. However, due to the requirements
of the 802.1Q VLAN standard, STP blocks unmeshed redundant physical links
even if they are in separate VLANs. This could result in blocking links unnec-
essarily. Switch meshing can allow use of STP without the problem of blocking
links that could remain open. For more information, refer to “Load Balancing:
Switch Meshing” on page 6-80, and “Spanning Tree Protocol” on page 6-39.
