Command Usage
• Spanning Tree Protocol
Uses RSTP for the internal state machine, but sends only 802.1D
BPDUs. This creates one spanning tree instance for the entire
network. If multiple VLANs are implemented on a network, the
path between specific VLAN members may be inadvertently
disabled to prevent network loops, thus isolating group members.
When operating multiple VLANs, we recommend selecting the
MSTP option.
