power priority through the CLI. Dell EMC Networking also honors the power priority value the powered device sends;
however, the CLI configuration takes precedence.
Power Value Dell EMC Networking advertises the maximum amount of power that can be supplied on the port.
By default the power is 15.4W, which corresponds to a power value of 130, based on the TIA-1057 specification. You
can advertise a different power value using the max-milliwatts option with the power inline auto | static
command. Dell EMC Networking also honors the power value (power requirement) the powered device sends when the port
is configured for power inline auto.

Configure LLDP
Configuring LLDP is a two-step process.
1. Enable LLDP globally.
2. Advertise TLVs out of an interface.

Important Points to Remember
LLDP is enabled by default.
Dell EMC Networking systems support up to eight neighbors per interface.
Dell EMC Networking systems support a maximum of 8000 total neighbors per system. If the number of interfaces multiplied
by eight exceeds the maximum, the system does not configure more than 8000.
INTERFACE level configurations override all CONFIGURATION level configurations.
LLDP is not hitless.
LLDP Compatibility
Spanning tree and force10 ring protocol blocked ports allow LLDPDUs.
802.1X controlled ports do not allow LLDPDUs until the connected device is authenticated.
CONFIGURATION versus INTERFACE Configurations
All LLDP configuration commands are available in PROTOCOL LLDP mode, which is a sub-mode of the CONFIGURATION mode
and INTERFACE mode.
Configurations made at the CONFIGURATION level are global; that is, they affect all interfaces on the system.
Configurations made at the INTERFACE level affect only the specific interface; they override CONFIGURATION level
configurations.
