Configuring MSTP 201
Configuring the Port
Connection with the
Point-to-Point Link
The point-to-point link directly connects two switches.
You can configure the port to connect or not connect with the point-to-point link
in the following ways.
Configuring in System View
Perform the following configuration in system view.
Configuring in Ethernet Port View
Perform the following configuration in Ethernet port view.
For more about the commands, see the Switch 7750 Command Reference Guide.
The ports connected with the point-to-point link, upon some port role conditions
being met, can transit to forwarding state rapidly through transmitting
synchronization packet, thus reducing the unnecessary forwarding delay. If the
parameter is configured in auto mode, MSTP will automatically detect if the
current Ethernet port is connected with the point-to-point link.
For a link aggregation, only the master port can be configured to connect with the
point-to-point link. If a port in auto-negotiation mode operates in full-duplex
mode upon negotiation, it can be configured to connect with the point-to-point
link.
This configuration takes effect on the CIST and all the MSTIs. The settings of a port
determine whether or not the point-to-point link will be applied to all the STIs to
which the port belongs. Note that a temporary loop may be redistributed if you
