PLANET WGSW-52040 - Manual (Page 337)

19-106
IEEE802.1D STP mode, this command is invalid.
Example:
Force the port 1/2 to run in the MSTP mode.
Switch(Config-If-Ethernet1/2)#spanning-tree mcheck
19.1.18 spanning-tree mode
Command:
spanning-tree mode {mstp | stp | rstp}
no spanning-tree mode
Function:
Set the spanning-tree mode in the switch; the command “no spanning-tree mode” restores the default setting.
Parameter:
19.1.19 mstp sets the switch in IEEE802.1s MSTP mode; stp sets
the switch in IEEE802.1D STP mode; rstp sets the switch in
IEEE802.1D RSTP mode.
Command mode:
Global Mode
Default:
The switch is in the MSTP mode by default.
Usage Guide:
When the switch is in IEEE802.1D STP mode, it only sends standard IEEE802.1D BPDU and TCN BPDU. It drops
any MSTP BPDUs.
Example:
Set the switch in the STP mode.
Switch(config)#spanning-tree mode stp
