High-Availability Support

To support high availability during a failover from the active supervisor engine to the standby supervisor engine, the per-port power management and phone status information is synchronized between the active and standby supervisor engines.

The information to be synchronized (on a per-port basis) is the presence of a phone, the phone power status (on, off, denied, or faulty), allocated power, device class, device type, device maximum power, and device discovery. The active supervisor engine sends this information to the standby supervisor engine, and the standby supervisor engine updates its internal data structures. When a switchover occurs, the standby supervisor engine allocates the power to the modules and ports from the available power, one module at a time. Once the power for each module has been allocated, the supervisor engine allocates the power to the phones, beginning with the lowest slot number, until all inline powered ports have been either powered on, off, or denied.

Switching module will not discover the phone because CDP is not supported. However, the supervisor engine detects the phone and powers it up.

Phone is inserted but has not booted, then phone is removed. A network device is plugged in. Inline power might damage the network device.
