1.2.6 MSTP Operation Mode Configuration
A MSTP-enabled switch can operate in one of the following operation modes:
STP-compatible mode: In this mode, the protocol packets sent out of the ports of
the switch are STP packets. If the switched network contains STP-enabled
switches, you can configure the current MSTP-enabled switch to operate in this
mode by using the stp mode stp command.
RSTP-compatible mode: In this mode, the protocol packets sent out of the ports of
the switch are RSTP packets. If the switched network contains RSTP-enabled
switches, you can configure the current MSTP-enabled switch to operate in this
mode by using the stp mode rstp command.
MSTP mode: In this mode, the protocol packets sent out of the ports of the switch
are MSTP packets, or STP packets if the ports have STP-enabled switches
connected. In this case, the multiple spanning tree function is enabled as well.
