I. Configuration procedure
Follow these steps to configure the maximum transmission rate of a port or a group of
ports:

Required
Use either command.
Configurations made in
Ethernet interface view will
take effect on the current
port only; configurations
made in port group view
will take effect on all ports
in the port group.
Configure the maximum
transmission rate of the
port(s)
stp transmit-limit
packet-number
Optional
10 by default
 Note:
If the maximum transmission rate setting of a port is too big, the port will send a large
number of MSTP packets within each hello time, thus using excessive network
resources. We recommend that you use the default setting.
II. Configuration example
# Set the maximum transmission rate of port GigabitEthernet 2/0/1 to 5.
<Sysname> system-view
[Sysname] interface GigabitEthernet 2/0/1
[Sysname-GigabitEthernet2/0/1] stp transmit-limit 5
1.3.10 Configuring Ports as Edge Ports
If a port directly connects to a user terminal rather than another device or a shared LAN
segment, this port is regarded as an edge port. When a network topology change
occurs, an edge port will not cause a temporary loop. Therefore, if you specify a port as
an edge port, this port can transition rapidly from the blocked state to the forwarding
state without delay.
