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.
