POWER-ETHERNET-MIB

Integer32 (1..2147483647)

This variable uniquely identifies the group containing the port to which a power Ethernet PSE is connected. Group means box in the stack, module in a rack and the value 1 MUST be used for non-modular devices. Furthermore, the same value MUST be used in this variable, pethMainPseGroupIndex, and pethNotificationControlGroupIndex to refer to a given box in a stack or module in the rack.

Integer32 (1..2147483647)

This variable uniquely identifies the power Ethernet PSE port within group pethPsePortGroupIndex to which the power Ethernet PSE entry is connected.

TruthValue1 = true2 = falseRepresents a boolean value. · Integer32

Reference: IEEE Std 802.3af Section 30.9.1.1.2 aPSEAdminState

true (1) An interface which can provide the PSE functions. false(2) The interface will act as it would if it had no PSE function.

TruthValue1 = true2 = falseRepresents a boolean value. · Integer32

Reference: IEEE Std 802.3af Section 30.9.1.1.3 aPSEPowerPairsControlAbility

Describes the capability of controlling the power pairs functionality to switch pins for sourcing power. The value true indicate that the device has the capability to control the power pairs. When false the PSE Pinout Alternative used cannot be controlled through the PethPsePortAdminEnable attribute.

INTEGER1 = signal2 = spare · Integer32

Reference: IEEE Std 802.3af Section 30.9.1.1.4 aPSEPowerPairs

Describes or controls the pairs in use. If the value of pethPsePortPowerPairsControl is true, this object is writable. A value of signal(1) means that the signal pairs only are in use. A value of spare(2) means that the spare pairs only are in use.

INTEGER1 = disabled2 = searching3 = deliveringPower4 = fault5 = test6 = otherFault · Integer32

Reference: IEEE Std 802.3af Section 30.9.1.1.5 aPSEPowerDetectionStatus

Describes the operational status of the port PD detection. A value of disabled(1)- indicates that the PSE State diagram is in the state DISABLED. A value of deliveringPower(3) - indicates that the PSE State diagram is in the state POWER_ON for a duration greater than tlim max (see IEEE Std 802.3af Table 33-5 tlim). A value of fault(4) - indicates that the PSE State diagram is in the state TEST_ERROR. A value of test(5) - indicates that the PSE State diagram is in the state TEST_MODE. A value of otherFault(6) - indicates that the PSE State diagram is in the state IDLE due to the variable error_conditions. A value of searching(2)- indicates the PSE State diagram is in a state other than those listed above.

INTEGER1 = critical2 = high3 = low · Integer32

This object controls the priority of the port from the point of view of a power management algorithm. The priority that is set by this variable could be used by a control mechanism that prevents over current situations by disconnecting first ports with lower power priority. Ports that connect devices critical to the operation of the network - like the E911 telephones ports - should be set to higher priority.

Counter32

Reference: IEEE Std 802.3af Section 30.9.1.1.11 aPSEMPSAbsentCounter

This counter is incremented when the PSE state diagram transitions directly from the state POWER_ON to the state IDLE due to tmpdo_timer_done being asserted.

SnmpAdminStringAn octet string containing administrative information, preferably in human-readable form. To facilitate internationalization, this information is represented using the ISO/IEC IS 10646-1 character set, encoded as an octet string using the UTF-8 transformation format described in [RFC2279]. Since additional code points are added by amendments to the 10646 standard from time to time, implementations must be prepared to encounter any code point from 0x00000000 to 0x7fffffff. Byte sequences that do not correspond to the valid UTF-8 encoding of a code point or are outside this range are prohibited. The use of control codes should be avoided. When it is necessary to represent a newline, the control code sequence CR LF should be used. The use of leading or trailing white space should be avoided. For code points not directly supported by user interface hardware or software, an alternative means of entry and display, such as hexadecimal, may be provided. For information encoded in 7-bit US-ASCII, the UTF-8 encoding is identical to the US-ASCII encoding. UTF-8 may require multiple bytes to represent a single character / code point; thus the length of this object in octets may be different from the number of characters encoded. Similarly, size constraints refer to the number of encoded octets, not the number of characters represented by an encoding. Note that when this TC is used for an object that is used or envisioned to be used as an index, then a SIZE restriction MUST be specified so that the number of sub-identifiers for any object instance does not exceed the limit of 128, as defined by [RFC3416]. Note that the size of an SnmpAdminString object is measured in octets, not characters. SIZE (0..255) · OCTET STRING · hint 255t

A manager will set the value of this variable to indicate the type of powered device that is connected to the port. The default value supplied by the agent if no value has ever been set should be a zero-length octet string.

INTEGER1 = class02 = class13 = class24 = class35 = class4 · Integer32

Reference: IEEE Std 802.3af Section 30.9.1.1.6 aPSEPowerClassification

Classification is a way to tag different terminals on the Power over LAN network according to their power consumption. Devices such as IP telephones, WLAN access points and others, will be classified according to their power requirements. The meaning of the classification labels is defined in the IEEE specification. This variable is valid only while a PD is being powered, that is, while the attribute pethPsePortDetectionStatus is reporting the enumeration deliveringPower.

This counter is incremented when the PSE state diagram enters the state SIGNATURE_INVALID.

This counter is incremented when the PSE state diagram enters the state POWER_DENIED.

Counter32

Reference: IEEE Std 802.3af Section 30.9.1.1.9 aPSEOverLoadCounter

This counter is incremented when the PSE state diagram enters the state ERROR_DELAY_SHORT.
