Parameters
auto: Configures the port(s) to recognize the MSTP BPDU format automatically and accordingly
determine the format of MSTP BPDUs to send.
dot1s: Configures the port(s) to receive and send only standard-format (802.1s-compliant) MSTP
BPDUs.
legacy: Configures the port(s) to receive and send only compatible-format MSTP BPDUs.
Description
Use the stp compliance command to configure the mode the specified port(s) will use to recognize and
send MSTP BPDUs.
Use the undo stp compliance command to restore the system default.
By 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.
Note that:
z Configured in Layer 2 Ethernet port view, the setting takes effect on the current port only;
configured in port group view, the setting takes effect on all ports in the port group.
z Configured in Layer 2 aggregate port view, the setting takes effect only on the aggregate port;
configured on a member port in an aggregation group, the setting can take effect only after the port
leaves the aggregation group.
