connection failure occurs, the backup port will automatically become a
working port to recover.
The switch can be set in the ring master or slave mode. The ring master
negotiates and places commands to the other switches in the X-Ring group.
If there are two or more switches in the master mode, the software will
select the switch with lowest MAC address number as the ring master. The
X-Ring master mode is enabled using the X-Ring configuration interface.
The Ring Master can also be identified using the R.M. LED on the front of
the switch.
The switch also supports coupling ring to connect two or more X-Ring
groups for redundant backup. The dual homing function is used to prevent a
connection lose between the X-Ring group and the upper level/core switch.
