Xtreme Ring
Xtreme Ring provides a faster redundant recovery than Spanning Tree topology. The
action is similar to STP or RSTP, but the algorithms not the same.
In the Xtreme Ring topology, every switch should enable Xtreme Ring function and
assign two member ports in the ring. Only one switch in the Xtreme Ring group would be
set as a backup switch that would be blocked, called backup port, and another port is
called working port. Other switches are called working switches
and their two member
ports are called working ports. When the failure of network connection occurs, the
backup port will automatically become a working port to recovery the failure.
The switch supports the function and interface for setting the switch as the ring master or
slave mode. The ring master can negotiate and place command to other switches in the
Xtreme Ring group. If there are 2 or more switches in master mode, then software will
select the switch with lowest MAC address number as the ring master. The Xtreme Ring
master ring mode will be enabled by the Xtreme Ring configuration interface. Also, user
can identify the switch as the ring master from the R.M. LED panel of the LED panel on
the switch.
The system also supports the coupling ring that can connect 2 or more Xtreme Ring
group for the redundant backup function and dual homing function that prevent
connection lose between Xtreme Ring group and upper level/core switch.
