Extended Power via MDI TLV<br />

The Extended Power via MDI TLV enables advanced PoE management between LLDP-MED endpoints<br />

and network connectivity devices. Advertise <strong>the</strong> Extended Power via MDI on all ports that are connected<br />

to an 802.3af powered, LLDP-MED endpoint device.<br />

• Power Type—<strong>the</strong>re are two possible power types: Power Sourcing Entity (PSE) or Power Device<br />

(PD). The <strong>Force10</strong> system is a PSE, which corresponds to a value of 0, based on <strong>the</strong> TIA-1057<br />

specification.<br />

• Power Source—<strong>the</strong>re are two possible power sources: Primary and Backup. The <strong>Force10</strong> system is a<br />

Primary Power Source, which corresponds to a value of 1, based on <strong>the</strong> TIA-1057 specification.<br />

• Power Priority—<strong>the</strong>re are three possible priorities: Low, High, and Critical. Ports on <strong>the</strong> <strong>Force10</strong><br />

system have a “High” power priority, which corresponds to a value of 2, based on <strong>the</strong> TIA-1057<br />

specification.<br />

• Power Value—<strong>the</strong> maximum amount of power that a PSE can supply, or <strong>the</strong> amount of power that <strong>the</strong><br />

PD requires. The <strong>Force10</strong> system can supply a maximum of 15.4 Watts per port which corresponds to<br />

a Power Value of 130, based on <strong>the</strong> TIA-1057 specification.<br />

Configuring LLDP is a two-step process:<br />

1. Enable LLDP globally. See page 292.<br />

2. Advertise TLVs out of an interface. See page 292.<br />
