Extended Power via MDI TLV
The extended power via MDI TLV enables advanced PoE management between LLDP-MED endpoints and network connectivity devices.
Advertise the extended power via MDI on all ports that are connected to an 802.3af powered, LLDP-MED endpoint device.
• Power Type — there are two possible power types: power source entity (PSE) or power device (PD). The Dell Networking system is a
PSE, which corresponds to a value of 0, based on the TIA-1057 specification.
• Power Source — there are two possible power sources: primary and backup. The Dell Networking system is a primary power source,
which corresponds to a value of 1, based on the TIA-1057 specification.
• Power Priority — there are three possible priorities: Low, High, and Critical. On Dell Networking systems, the default power priority is
High, which corresponds to a value of 2 based on the TIA-1057 specification. You can configure a different power priority through the
CLI. Dell Networking also honors the power priority value the powered device sends; however, the CLI configuration takes precedence.
• Power Value — Dell 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 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.

• Viewing the LLDP Configuration
• Viewing Information Advertised by Adjacent LLDP Agents
• Configuring LLDPDU Intervals
• Configuring Transmit and Receive Mode
• Configuring a Time to Live
• Debugging LLDP

Important Points to Remember

• LLDP is enabled by default.
• Dell Networking systems support up to eight neighbors per interface.
• Dell 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.
