X-Ring
X-Ring provides a faster redundant recovery than Spanning Tree topology. The action is similar to STP or
RSTP, but the algorithms between them are not the same.
In the X-Ring topology, each switch should be enabled with the X-Ring function and two ports of each
switch should be configured as the member ports in the ring. Only one switch in the X-Ring group would
be set as the master switch that one of its two member ports, known as backup port, would be blocked
and the other port is called working port. Other switches in the X-Ring group are called working switches
and their two member ports are called working ports. When the failure of network connection occurs, the
backup port (blocked) of the master switch (Ring Master) will automatically become a working port to help
the entire group recover from the failure.
The switch supports the function and interface to configure the switch being a ring master. The ring
master can negotiate and place commands to other switches in the X-Ring group. If there are two or
more switches in master mode, the software will configure the switch with lowest MAC address number
as the ring master. The ring master mode can be enabled via the X-Ring configuration interface. Also, the
user can identify whether the switch is the ring master by checking the corresponding LED indicator on
the panel of the switch.
The system also supports the
Couple Ring
topology that can connect two X-Ring groups for the
redundant backup function. Besides, the
Dual Homing
topology can prevent connection lose between
the X-Ring group and the upper level/core switch.
•
Enable X-Ring
: To enable the X-Ring function, tick the checkbox beside the
Enable Ring
string label.
If this checkbox is not ticked, all the ring functions are unavailable.
¾
1st Ring Port
: Pull down
the selection menu to assign a port as the
1
st
Ring Port
that is the
working port.
¾
2nd Ring Port
: Pull down
the selection menu to assign a port as the
2
nd
Ring Port
that is the
backup port. When
1
st
Ring Port
fails, the system will automatically upgrade the
2
nd
Ring Port
to be the working port.
•
Enable Couple Ring
: To enable the coupe ring function, tick the check box beside the
Enable Couple
Ring
label.
¾
Coupling Port
: Assign the member port which is connected to the other ring group.
¾
Control Port
: When the
Enable Couple Ring
checkbox is ticked, you have to assign the
control port to form a couple-ring group between the two X-rings.
•
Enable Dual Homing
: Set up one of the ports on the switch to be the Dual Homing port. For a switch,
there is only one Dual Homing port.
Dual Homing function only works when the X-Ring function
enabled.
•
And then, click
Apply
to apply the configuration.
