### Admin Status (cpeExtPsePortEnable/pethPsePortAdminEnable)

cpeExtPsePortEnable

This object is an extension of the object pethPsePortAdminEnable. It allows you to be more specific when enabling power source entity (PSE) functionality. There are two possible values:

> auto—Enables powered device (PD) discovery on the interface.

> The amount of power allocated depends on the PD discovered. If the value of pethPsePortAdminEnable was false prior to this set operation, then it change to true.

> static—Enables PD discovery on the interface.

> This value differs from the value auto in that the amount of power allocated is based on the power sourcing equipment's configuration. If the value of pethPsePortAdminEnable was false prior to this set operation, then it change to true.

Note: The states auto and static correspond to the value true for the object pethPsePortAdminEnable. However, if the value of pethPsePortAdminEnable is false, then the value of this object is irrelevant.

pethPsePortAdminEnable

When the value of this object is true, an interface can provide PSE functionality. Also, this object will adopt the value auto.

When the value of this object is false, PSE functionality is disabled.

### IEEE Classifications (pethPsePortPowerClassifications)

This object allows you to tag terminals on the Power over LAN network with different classification labels according to their power consumption. Devices such as IP telephones and WLAN access points are classified according to their power requirements. The classification labels are defined in the IEEE specification.

Note: This object is valid only while a PD is being powered.

### Operational Status (pethPsePortDetectionStatus)

Operational status of the port PD detection. There are six possible values:

> disabled—the PSE State diagram is in the DISABLED state

> deliveringPower—the PSE State diagram has been in the POWER_ON state for a duration greater than the tlim max (see IEEE Std. 802.3af , Table 33-5 tlim)

> fault—the PSE State diagram is in the TEST_ERROR state

> test—the PSE State diagram is in the TEST_MODE state

> otherFault—the PSE State diagram is in the IDLE state due to the variable error_conditions

> searching—the PSE State diagram is in a state other than those listed above

### Port Type (pethPsePortType)

Indicates the type of PD that is connected to the port.

### Power Priority (pethPsePortPowerPriority)

Indicates the power priority of a port. When necessary, the agent will first disconnect ports with a lower power priority value.

### Power Pairs Control (pethPsePortPowerPairsControlAbility)

When the value of this object is true, the device is capable of controlling the power pairs functionality in order to switch pins for sourcing power.

When the value of this object is false, the PSE pinout alternative used cannot be controlled through the PethPsePortAdminEnable object.

### Power Pairs (pethPsePortPowerPairs)

Indicates which power pairs are in use. There are two possible values:

> signal—indicates that only the signal pairs are in use

> spare—indicates that only the spare pairs are in use

### Power Denied (PethPsePortPowerDeniedCounter)

Number of times the PSE state diagram has entered the POWER_DENIED state.
