By default, a port recognizes and sends
MSTP packets in the automatic mode.
That is, it determines the format of
packets to be sent according to the
format of the packets received.
Follow these steps to configure how a port recognizes and sends MSTP packets (in Ethernet port view):

format of the packets received.
Configuration example

Configuring the MSTP Operation Mode
To make an MSTP-enabled switch compatible with STP/RSTP, MSTP provides the following three
operation modes:
z
STP-compatible mode, where the ports of a switch send STP BPDUs to neighboring devices. If
STP-enabled switches exist in a switched network, you can use the stp mode stp command to
configure an MSTP-enabled switch to operate in STP-compatible mode.
z
RSTP-compatible mode, where the ports of a switch send RSTP BPDUs to neighboring devices. If
RSTP-enabled switches exist in a switched network, you can use the stp mode rstp command to
configure an MSTP-enabled switch to operate in RSTP-compatible mode.
z
MSTP mode, where the ports of a switch send MSTP BPDUs or STP BPDUs (if the switch is
connected to STP-enabled switches) to neighboring devices. In this case, the switch is
MSTP-capable.
