Parameter
auto: Sets the MSTP packet format as auto.
legacy: Sets the MSTP packet format as legacy.
dot1s: Sets the MSTP packet format as dot1s.
Description
Use the stp compliance command to set the MSTP packet format of a port.
Use the undo stp compliance command to restore the default MSTP packet format.
By default, the MSTP packet format is legacy.
With the MSTP packet format set to auto, the port automatically determines the
format of the packets to be transmitted according to that of the received MSTP
packets. If the format of the received packets changes repeatedly, MSTP will shut
down the corresponding port to prevent network storm. A port shut down in this
way can only be enabled again by the network administrator.
With the MSTP packet format set to legacy, the port only processes and
transmits MSTP packets in legacy format. If packets in dot1s format are received,
the corresponding ports are set as discarding ports to prevent network storm.
With the MSTP packet format set to dot1s, the port only processes and transmits
MSTP packets in dot1s format. If packets in legacy format are received, the
corresponding ports are set as discarding ports to prevent network storm.
All the ports in an aggregation group use the same MSTP packet format.
Example
# Configure MSTP packet format as dot1s (802.1s).
