When multiple paths exist between two points on a network, Spanning Tree Protocol (STP), or one 
of its enhanced variants, can prevent broadcast loops and ensure that the RackSwitch G8124 
(G8124) uses only the most efficient network path.

This chapter covers the following topics:

BLADEOS 6.5 supports the following STP modes:

Spanning Tree Protocol/Per-VLAN Spanning Tree Plus (STP/PVST+)

STP as defined in IEEE 802.1D (1998) allows devices to detect and eliminate logical loops in 
a bridged or switched network. When multiple paths exist, STP configures the network so that 
only the most efficient path is used. If that path fails, STP automatically configures the best 
alternative active path on the network in order to sustain network operations.

BLADEOS STP/PVST+ supports multiple instances of Spanning Tree, allowing one Spanning 
Tree Group (STG) per VLAN and is compatible with Cisco PVST+ mode.
