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.
