Spanning Tree Configuration
BLADEOS 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 VRRP is used for active/active redundancy, STG must be enabled.
