path cost for the other switch from this transmitting switch
at the specified port. When path cost insert in 0, the
switches will be setup as automatic data transmitting.
Priority (0~240)
Enter a number 0 through 240 to decide which port should
be blocked by priority in LAN.
The value of priority must be the multiple of 16
Admin P2P
Some of the rapid state transactions that are possible
within RSTP are dependent upon whether the port
concerned can only be connected to exactly one other
switch (i.e. It is served by a point-to-point LAN segment),
or it can be connected to two or more switches (i.e. It is
served by a shared medium LAN segment).
This function allows the P2P status of the link to be
manipulated administratively.
True means P2P enabling. False means P2P disabling.
Auto Edge
The port is directly connected to end stations, and it
cannot create bridging loop in the network. To configure
the port as an edge port, set the port to “
True
”.
Admin Non STP
The port includes the STP mathematic calculation.
True
is not including STP mathematic calculation.
False
is including the STP mathematic calculation.

MSTP (Multiple Spanning Tree Protocol)
It is defined in IEEE 802.1s; it can map a group of VLAN’s into a single Multiple Spanning Tree
instance (MSTI). In fact, the Spanning Tree Protocol is applied separately for a set of VLAN’s
instead of the whole network. Different root switches and different STP parameters can be
individually configured for each MSTI. So, one link can be active for one MSTI and the other link
active for the second MSTI. This enables some degree of load-balancing and generally two
MSTI’s are used in the network for easier implementation.
