Manage Power Priorities PoE-enabled ports have power access priorities based first on their configuration and then by line card and port number. The default prioritization is presented in Table 27-5. Note: For S-Series, where Table 27-5 refers to "line cards with the lowest slot number", substitute "S-Series stack members with the lowest unit ID".) Table 27-5. PoE Ports Priorities Configuration Ports configured with power inline static Ports configured with power inline auto Port Number Priority Ports with the lowest port numbers in line cards with the lowest 1 slot number Ports with the lowest port numbers 2 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 Power over Ethernet | 519
