Configuration takes effect immediately. You do not need to click Apply
or OK.
3. Click Advanced to configure supervisor-related parameters.
This table describes the Ring Parameters.
4. Configure desired supervisor-related parameters. This table describes the
parameters.
Click here to enable Supervisor
mode.
IMPORTANT We recommend that you use the default values for Beacon Interval,
Beacon Timeout and Ring Protocol VLAN ID.

Supervisor
Precedence You must configure a supervisor precedence number for each device
configured as a ring supervisor. The highest possible supervisor
precedence value is 255.
When multiple nodes are enabled as supervisor, the node with the
highest precedence value is assigned as the active ring supervisor; the
other nodes automatically become back-up supervisors.
We recommend that you complete these tasks:
• Configure back-up supervisor nodes.
• Set your desired Active Ring Supervisor with a relatively high
supervisor-precedence value compared to the back-up nodes.
• Keep track of your network’s supervisor-precedence values.
If multiple supervisors are configured with the same precedence value
(the factory default value for all supervisor-capable devices is 0), the
node with the numerically highest MAC address becomes the active
supervisor.

Beacon Interval Frequency of the active ring supervisor transmitting a beacon frame
through both of its Ethernet ports. This parameter is user configurable
for any time between 200
S and 100mS.
400
S
Beacon Timeout The beacon timeout is amount of time nodes wait before timing out
the reception of beacon frames and taking appropriate action.
Supervisors support a range from 400
S to 500mS.
