4.4.5 MSTP Port Configuration
This page allows configure the Port settings. Choose the Instance ID you want to
configure. The MSTP enabled and linked up ports within the instance will be
listed in this table.
Note that the ports not belonged to the Instance, or the ports not MSTP
activated will not display. The meaning of the Path Cost, Priority, Link Type and
Edge Port is the same as the definition of RSTP.
Path Cost: Enter a number between 1 and 200,000,000. This value represents the
“cost” of the path to the other bridge from the transmitting bridge at the
specified port.
Priority: Enter a value between 0 and 240, using multiples of 16. This is the value
that decides which port should be blocked by priority in a LAN.
Link Type: There are 3 types for you select. Auto, P2P and Share.
Some of the rapid state transitions that are possible within RSTP depend upon
whether the port of concern can only be connected to another bridge (i.e. it is
served by a point-to-point LAN segment), or if it can be connected to two or
more bridges (i.e. it is served by a shared-medium LAN segment). This function
allows link status of the link to be manipulated administratively. “Auto” means to
auto select P2P or Share mode. “P2P” means P2P is enabled, the 2 ends work in
Full duplex mode. While “Share” is enabled, it means P2P is disabled, the 2 ends
may connect through a share media and work in Half duplex mode.
Edge: A port directly connected to the end stations cannot create a bridging loop
in the network. To configure this port as an edge port, set the port to the Enable
state. When the non-bridge device connects an admin edge port, this port will be
