Configure Switch Features Chapter 7
Active Supervisor Precedence Displays the precedence that is assigned to the ring supervisor.
You assign the precedence value on the Advanced Network Configuration dialog box. See
Table 48.
Enable Supervisor Mode Check to make the switch a ring supervisor. The configuration takes effect immediately.
Ring Faults Detected Displays the number of faults that are currently detected in the ring.
When a DLR network is powered-up, the supervisor can detect ring faults as a result of powering up before other devices on the
network. You can use an MSG instruction to clear the faults.
Supervisor Status Displays whether the switch is operating as the active ring supervisor or back-up ring supervisor.
Valid values:
• Active
• Backup
Last Active Node on Port 1 Displays the IP address of the last active node on DLR port 1.
Last Active Node on Port 2 Displays the IP address of the last active node on DLR port 2.

Supervisor Precedence Type a precedence value to assign to the ring supervisor. When multiple supervisors are configured, the precedence value determines
the active ring supervisor. Only one supervisor can be active at one time. The precedence is transmitted in beacon frames.
When two supervisors have the same precedence, the device with the numerically highest MAC address becomes the active
supervisor.
Valid values: 0…255.
The default precedence is 0.
The highest precedence is 255.
