MSTP Configuration Commands
1-35
If no keyword is specified in the stp point-to-point command, the auto keyword is
used by default, and so MSTP automatically determines the type of the link connected
to the current port.
The rapid transition function is not applicable to ports on non-point-to-point links.
If an Ethernet port is the master port of an aggregation port or operates in full-duplex
mode, the link connected to the port is a point-to-point link.
You are recommended to let MSTP automatically determine the link types of ports.
These two commands only apply to CISTs and MSTIs. If you configure the link to which
a port is connected is a point-to-point link (or a non-point-to-point link), the configuration
applies to all MSTIs (that is, the port is configured to connect to a point-to-point link [or
a non-point-to-point link] in all MSTIs). If the actual physical link is not a point-to-point
link and you configure the link to which the port is connected to be a point-to-point link,
loops may temporarily occur.

1.1.33 stp port priority
Syntax
stp [ instance instance-id ] port priority priority
undo stp [ instance instance-id ] port priority
View
Ethernet port view
Parameters
instance-id: MSTI ID ranging from 0 to 16. A value of 0 specifies the CIST.
port priority priority: Sets the port priority. The priority argument ranges from 0 to 240
and must be a multiple of 16 (such as 0, 16, and 32). The default port priority of a port in
any MSTI is 128.
Description
Use the stp port priority command to set the port priority of the current port in the
specified MSTI.
