Advertising the Extended Power through MDI
The power device sends the following information in the LLDP-MED extended power-via-MDI TLV.
1. Power Requirement: Dell Networking OS uses it for power allocation
2. Power Priority — Critical, High, or Low: Dell Networking OS uses it for power priority calculation.
3. External Power Source: Dell Networking OS does not use this information. IEEE 802.3at power-via-mdi TLV
To configure the system or an interface to advertise IEEE 802.1ab extended power-via-mdi TLV, use the advertise med
power-via-mdi command.
When you enable the advertise med power-via-mdi command in CONFIGURATION mode, advertisement is enabled for
all the interfaces. To enable advertisement for a specific interface, use INTERFACE Configuration mode.
NOTE
: If you also configure LLDP to use the 802.3 TLV format, 802.3 overrides the advertise med power-via-mdi
settings. For more information, see Advertising Extended Power Though dot3–TLVs.
Parameters
power-via-mdi — Enter the keyword power-via-mdi to advertise IEEE 802.1ab MED Extended power-via-mdi TLV.
• Configure the system or an interface to advertise IEEE 802.1ab extended power-via-mdi TLV.
LLDP CONFIGURATION or INTERFACE LLDP CONFIGURATION mode

Example of Advertising the Extender Power through MDI TLVs in LLDP Configuration Mode
The following example configures all the interfaces to advertise IEEE 802.1ab power through MDI.
Dell(conf-lldp)#advertise med power-via-mdi
Example of Advertising the Extender Power through MDI TLVs in Interface LLDP Configuration Mode
The following example configures interface peGigE 0/0/1 to advertise IEEE 802.1ab power through MDI.
Dell(conf)#interface peGigE 0/0/1
Dell(conf-if-pegi-0/0/1)#protocol lldp
Dell(conf-if-pegi-0/0/1-lldp)#advertise med power-via-mdi
Advertising Extended Power Though dot3–TLVs
The power device sends the following information in the IEEE 802.3 power-via-mdi TLV.
1. Power Class — Dell Networking OS honors and displays the power class in the show power inline command in EXEC
mode (the PD-requested power value must be within the class max watts limit).
2. Type — Dell Networking OS uses type only when the type is Type1 or Type2 PD and displays the type in the show power
inline
command in EXEC mode. The Dell Networking OS does not use Type1 or Type2 PSE requests.
3. Priority — Dell Networking OS uses priority for priority calculation.
