Configuration in system view
Perform the following configuration in system view.
Table 126 Configure the port (not) to connect with the point-to-point link
Operation
Configure the port to connect with the
point-to-point link
Configure the port not to connect with the
point-to-point link
Configure MSTP to automatically detect if the
port is directly connected with the
point-to-point link
Configure MSTP to automatically detect if the
port is directly connected with the
point-to-point link, as defaulted
Configuration in Ethernet port view
Perform the following configuration in Ethernet port view.
Table 127 Configure the port (not) to connect with the point-to-point link
Operation
Configure the port to connect with the
point-to-point link
Configure the port not to connect with the
point-to-point link
Configure MSTP to automatically detect if the
port is directly connected with the
point-to-point link
Configure MSTP to automatically detect if the
port is directly connected with the
point-to-point link, as defaulted
You can configure the port (not) to connect with the point-to-point link with
either of the earlier-mentioned measures. For the ports connected with the
point-to-point link, upon some port role conditions met, they can transit to
forwarding state fast through transmitting synchronization packet, thereby
reducing the unnecessary forwarding delay. If the parameter is configured as auto
mode, MSTP will automatically detect if the current Ethernet port is connected
with the point-to-point link.
n
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
whether to connect 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 configure
a port that is not physically connected with the point-to-point link as connected to
such a link by force.
By default, the parameter is configured as auto.
