Configure the
maximum transmitting
speed
As the maximum transmitting speed parameter determines the number of the
configuration BPDUs transmitted in each Hello time, set it to a proper value to avoid
MSTP from occupying too many network resources. The default is recommended.
Configuration example
1 Set the maximum transmitting speed of GigabitEthernet1/0/1 port to 5.

Edge Port
Edge ports are ports that neither directly connects to other switches nor indirectly
connects to other switches through network segments. After a port is configured as
Configuration
an edge port, rapid transition is applicable to the port. That is, when the port changes
from blocking state to forwarding state, it does not have to wait for a delay.
You can configure a port as an edge port in the following two ways.
