5.6.6.5 X-Ring Configuration
The Managed Industrial Switch supports the function and interface for setting the switch as the ring master or not. The ring
master can negotiate and place command to other switches in the X-Ring group. If there are 2 or more switches in master
mode, the software will select the switch with lowest MAC address number as the ring master. The X-Ring master ring
mode can be enabled by setting the X-Ring configuration interface. Also, the user can identify whether the switch is the
ring master by checking the
R.M.
LED indicator on the panel of the Switch.
The system also supports the
Couple Ring
that can connect 2 or more X-Ring group for the redundant backup function;
Dual Homing
function that can prevent connection lose between X-Ring group and upper level/core switch. Apart from
the advantages,
Dual Ring
can handle 2 rings in the system and has the ability to recover from failure within 20
milliseconds.
