II. Configuration procedure (in Ethernet port view)
Follow these steps to configure the maximum transmitting speed in Ethernet port view:
To do ...
Enter system view
Enter Ethernet port
view
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 value is
recommended.
III. Configuration example
# Set the maximum transmitting speed of Ethernet2/0/1 to 15.
1) Configure the maximum transmitting speed in system view.
<H3C> system-view
[H3C] stp interface ethernet2/0/1 transmit-limit 15
2) Configure the maximum transmitting speed in Ethernet port view.
<H3C> system-view
[H3C] interface ethernet2/0/1
[H3C-Ethernet2/0/1] stp transmit-limit 15
1.2.11 Edge Port Configuration
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 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 any delay.
You can configure a port as an edge port in the following two ways.
Use the command ...
system-view
stp interface interface-list
transmit-limit packetnum
Use the command ...
system-view
interface interface-type
interface-number
stp transmit-limit
