4-32
The administrator can use this interface to configure path cost and priority of every port.
Port Select the port that you want to configure.
Path Cost
This feature allows the administrator to configure the cost of the path to
the other bridge from this transmitting bridge at the specified port. Enter a
number between 1 and 200000000.
Priority
This feature allows the administrator to configure which port should be
blocked by priority in LAN. Enter a number between 0 and 240. 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 bridge (i.e. it is served by a point-to-point LAN
segment), or 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 is to enable P2P
function. False is to disable P2P.
Admin Edge
The port directly connected to end stations 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.

4-6.17 X-Ring Configuration
HME-421E/423E provides redundant self-recovery mechanism named as X-Ring. When compared with the
commercial standard redundant technologies like STP or RSTP, the X-Ring can effectively reduce the
recovery time to less than 300ms. The Ring Topology must be applied to all the connected switches.
When all switches are connected in a ring topology with X-Ring function enabled, one of the switches will be
appointed as “Ring Master.” The ring master will monitor the ring’s health to make sure the ring is working
properly. Once a failure is detected by the ring master, the ring master will activate the blocked backup path
within milliseconds to replace the faulty primary transmission path to make sure the ring will continue to work.
In the X-Ring topology, every switch should enable X-Ring function and assign two member ports to form the
