Enabling The Mstp Feature - H3C S5500-SI Series Operation Manual

a port on your command line. After your configuration, when working in MSTP mode,
the port sends and receives only MSTP packets of the format you have configured.
I. Configuration procedure
Follow these steps to configure the MSTP packet format for a port or a group of ports:
To do...
Enter system view
Enter
Ethernet
interface
view or
port
group
view
Configure the MSTP
packet format for the
port(s)
Note:
If the port is configured not to detect the packet format automatically while it works in
the MSTP mode, and if it receives a packet in the format other than as configured,
that port will become a designated port, and the port will remain in the discarding
state to prevent the occurrence of a loop.
If a port receives MSTP packets of different formats frequently, this means that the
MSTP packet formation configuration contains error. In this case, if the port is
working in MSTP mode, it will be disabled for protection. Those ports closed thereby
can be restored only by the network administers.
II. Configuration example
# Configure port GigabitEthernet 1/0/1 to receive and send standard-format MSTP
packets.
