Configure the mode a port 
recognizes and sends MSTP 
packets 

{ auto | dot1s 

| legacy } 

Required 
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. 

 

# Configure GigabitEthernet 1/0/1 to recognize and send packets in dot1s format. 

<device> system-view 

[device] interface GigabitEthernet1/0/1 

[device-GigabitEthernet1/0/1] stp compliance dot1s 

# Restore the default mode for GigabitEthernet 1/0/1 to recognize/send MSTP packets. 

[device-GigabitEthernet1/0/1] undo stp compliance 

To make a MSTP-enabled device compatible with STP/RSTP, MSTP provides the following three 
operation modes: 

z

 

STP-compatible mode, where the ports of a device send STP BPDUs to neighboring devices. If 
STP-enabled devices exist in a switched network, you can use the stp mode stp command to 
configure an MSTP-enabled device to operate in STP-compatible mode. 

z

 

RSTP-compatible mode, where the ports of a device send RSTP BPDUs to neighboring devices. If 
RSTP-enabled devices exist in a switched network, you can use the stp mode rstp command to 
configure an MSTP-enabled device to operate in RSTP-compatible mode. 

z

 

MSTP mode, where the ports of a device send MSTP BPDUs or STP BPDUs (if the device is 
connected to STP-enabled devices) to neighboring devices. In this case, the device is 
MSTP-capable.  

Follow these steps to configure the MSTP operation mode:

Required 
An MSTP-enabled device 
operates in the MSTP mode by 
default.
