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.
• Rapid Spanning Tree Protocol
RSTP supports connections to either STP or RSTP nodes by
monitoring the incoming protocol messages and dynamically
adjusting the type of protocol messages the RSTP node transmits, as
described below:
- STP Mode – If the switch receives an 802.1D BPDU after a port’s
migration delay timer expires, the switch assumes it is connected to
an 802.1D bridge and starts using only 802.1D BPDUs.
- RSTP Mode – If RSTP is using 802.1D BPDUs on a port and
receives an RSTP BPDU after the migration delay expires, RSTP
