Spanning Tree Configuration
BLADE OS supports the IEEE 802.1D Spanning Tree Protocol (STP). STP is used to prevent loops
in the network topology. Up to 128 Spanning Tree Groups can be configured on the switch (STG
128 is reserved for management).
Note – When RSTP is turned on, only STG 1 can be configured.
