View

Parameters
stp: Specifies the STP-compatible mode.
mstp: Specifies the MSTP mode.
rstp: Specifies the RSTP-compatible mode.
Description
Use the stp mode command to set the operating mode of an MSTP-enabled switch.
Use the undo stp mode command to restore the default operating mode of an MSTP-enabled switch.
By default, an MSTP-enabled switch operates in MSTP mode.
To make a switch compatible with STP and RSTP, MSTP provides following three operating modes.
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.
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.
MSTP mode, where the ports of a switch send MSTP BPDUs and STP BPDUs (if the switch is
connected to STP-enabled switches) to neighboring devices. In this case, the switch is
MSTP-capable.
