H3C MSR Series Command Reference Manual page 74

Default
A port automatically recognizes the formats of received MSTP packets and determines the formats
of MSTP packets to be sent based on the recognized formats.
Views
Ethernet interface view, port group view, Layer 2 aggregate interface view
Default command level
2: System level
Parameters
auto: Configures the ports to recognize the MSTP BPDU format automatically and determine the
format of MSTP BPDUs to send.
dot1s: Configures the ports to receive and send only standard-format (802.1s-compliant) MSTP
BPDUs.
legacy: Configures the ports to receive and send only compatible-format MSTP BPDUs.

Configured in Ethernet interface view, the setting takes effect only on that interface.
Configured in port group view, the setting takes effect on all member ports in the port group.
Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate
interface.
Configured on a member port in an aggregation group, the setting takes effect only after the port
leaves the aggregation group.
Examples
# Configure Ethernet 1/1 to receive and send only standard-format (802.1s) MSTP packets.
