Setting the STP Version Parameter

Note: The default spanning tree mode in SFTOS is IEEE 802.1s (MSTP), which is
backward-compatible with IEEE 802.1D and IEEE 802.1w. Those legacy modes are available in
SFTOS, as described below.
To change to the legacy IEEE 802.1D mode, set the STP operational mode to disabled, then enable
the IEEE 802.1D mode. With the IEEE 802.1D mode operationally enabled, the rapid
configuration and multiple instances features are not available. If the rapid configuration and
multiple instances capabilities are required, use the IEEE 802.1s mode.

• - STP BPDUs are transmitted rather than MST BPDUs (IEEE 802.1D functionality supported)
802.1d
• - RST BPDUs are transmitted rather than MST BPDUs (IEEE 802.1w functionality supported)
802.1w
