Table 39-5. PoE Ports Priorities Configuration Ports configured with power inline auto Port Number Priority Ports with the lowest port numbers in line cards with the lowest 3 slot number Ports with the lowest port numbers 4 You can augment the default prioritization using the command [no] power inline priority {critical | high | low}, where critical is the highest priority, and low is the lowest. FTOS ignores any LLDP-MED priority on this port if you configure a priority with this command. If you do not configure a port priority with this command, FTOS honors any LLDP-MED priority. In general, priority is assigned in this order: 1. power inline [static | auto] setting: power inline static ports have a higher priority than power inline auto ports 2. power inline priority {critical | high | low} setting or LLDP-MED TLV, if power inline priority is not configured 3. slot ID 4. port ID Recover from a Failed Power Supply If ports are PoE-enabled, and a PSU fails, power might be terminated on some ports to compensate for the power loss. This does not affect PoE individual port configurations. For C-Series, use the show power supply command to display PSU status (refer to the example below). For S-Series, refer to the Power over Ethernet (PoE) chapter in the FTOS Command Reference for the S-Series for an example of the output of the show power inline output and its field descriptions.

Ports with the lowest priority are terminated first (refer to Manage Power Priorities). Power over Ethernet | 743
