Switch 7700 Command reference Guide, v2.0

308 CHAPTER 8: USING STP COMMANDS
If there is any bridge running STP on the segment connected to the current
Ethernet port, the port will switch to run RSTP in STP compatible mode. If the
network is rather stable, even when the bridge running STP on the segment is
removed, the corresponding port will still work in the STP compatible mode. In this
case, you can use this command to force the port to work in RSTP mode. In RSTP
mode, when the port receives an STP packet, it will transition to the STP
compatible mode.
The configuration can only be performed when the bridge runs in RSTP mode. If
the bridge is configured to work in STP compatible mode, the command will not
make any sense.
Related command: stp mode.
Example
Set the RSTP of Ethernet1/0/1 to work in RSTP mode.
[SW7700-Ethernet1/0/1]stp mcheck
stp mode Syntax
stp mode { stp | rstp }
undo stp mode

Parameter
stp: Specifies to run RSTP in STP compatible mode.
rstp: Specifies to run RSTP in RSTP mode.
Description
Using the stp mode command, you can configure the RSTP running mode. Using
the
undo stp mode command, you can restore the default RSTP running mode.
By default, the value is rstp.
This command can be used for specifying the current Ethernet switch to run the
RSTP in RSTP mode or in STP compatible mode.
Related commands: stp, stp mcheck.
Example
Set RSTP to work in STP compatible mode.
[SW7700]stp mode stp
stp point-to-point Syntax
stp point-to-point { force-true | force-false | auto }
undo stp point-to-point
