Per Port Configuration
Select the port you wish to configure and you will be able to view the current settings and status
of the port.
Path Cost
: Enter a number between 1 and 200,000,000. This value represents the “cost” of the
path to the other bridge from this 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.
Admin P2P
: Some of the rapid state transitions that are possible within RSTP depend upon
whether the port of concern can only be connected to one other 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 the P2P status of the link to be
manipulated administratively. “
True”
means P2P is enabled, while “
False”
means P2P is
disabled.
Admin 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
True
state.
Admin Non STP
: Status shown here indicates whether this port includes the STP mathematic
calculation.
True
means that this port does NOT include the STP mathematic calculation.
False
means that this port includes the STP mathematic calculation.
Once you finish your configuration, click

Note:
Always remember to select
Save Configuration
to save your settings. Otherwise, your
new settings will be lost when the switch is powered off.
Redundant Ring
Redundant ring technology provides a faster redundant media fail-over recovery than the
Spanning Tree Protocol (STP), or Rapid Spanning Tree Protocol (RSTP). But unlike STP/RSTP,
it additionally requires that all switches in the media ring be of the same brand (have the same
redundant ring method), as most redundant ring algorithms are proprietary and rarely
interoperable. Since STP and RSTP are standard IEEE protocols, switches that employ these
two methods of media redundancy are generally interoperable with one another.
With redundant ring, every switch in the ring must support the same redundant ring method and
have two ring member ports. One switch in this ring is dedicated to serve as Ring Master, and
one of its two member ports will be temporarily blocked--this is referred to as the backup port.
The other member port is called the working port. The other switches in the ring are called
working switches, and both their member ports are called working ports. When a segment of this
ring fails, the backup port/path will automatically become a working port/path to recover the
failure.
