CISCO-POWER-ETHERNET-EXT-MIB
AI MIB Summary
The CISCO-POWER-ETHERNET-EXT-MIB extends standard IEEE 802.3af/at Power over Ethernet (PoE) monitoring on Cisco Power Sourcing Equipment (PSE) to expose vendor-specific attributes such as power allocation policies, per-port power priority levels, and granular fault status indicators not defined in RFC 3621. This module enables precise management of inline power distribution on Cisco switches and power patch panels by tracking real-time power consumption, available power budgets, and detection anomalies for connected Powered Devices (PDs).
A MIB module for extending the POWER-ETHERNET-MIB (RFC3621) to add objects which provide additional management information about Power Sourcing Equipment (PSE) not available in POWER-ETHERNET-MIB.
Glossary
Power Sourcing Equipment (PSE) These are devices supplying electrical power to other equipment. They are, for example, inline power switches, inline power daughterboards and power patch panels.
Powered Device (PD) These are devices receiving their electrical power supply from Power Sourcing Equipment. They are, for example, IP telephones and wireless access points or bridges.

Glossary
Power Sourcing Equipment (PSE)
These are devices supplying electrical power to
other equipment. They are, for example, inline power
switches, inline power daughterboards and power patch
panels.
Powered Device (PD)
These are devices receiving their electrical power
supply from Power Sourcing Equipment. They are, for
example, IP telephones and wireless access points
or bridges. MODULE-IDENTITY .1.3.6.1.4.1.9.9.402 |
cpeExtMIBNotifs OBJECT IDENTIFIER .1.3.6.1.4.1.9.9.402.0 |
cpeExtPolicingNotifThis notification is generated when the 'overdraw' or
'overdrawLog' bit in value of cpeExtPsePortAdditionalStatus
is set or cleared. NOTIFICATION-TYPE .1.3.6.1.4.1.9.9.402.0.1 |
cpeExtMIBObjects OBJECT IDENTIFIER .1.3.6.1.4.1.9.9.402.1 |
cpeExtDefaultAllocationThis object indicates the default inline power allocation per
port. This is a global configuration parameter that applies
to all inline power capable ports in the system.
The system must consider this object as well as the per port
configuration object, cpeExtPsePortPwrMax, when determining
how much power to allocate to a port. The system will use the
lower of the two numbers.rw Unsigned32 UNITS "milliwatts" .1.3.6.1.4.1.9.9.402.1.1 |
cpeExtPsePortTableThis table extends the POWER-ETHERNET-MIB pethPsePortTable
for power Ethernet ports on a Powered Sourcing Equipment
(PSE) device. SEQUENCE OF CpeExtPsePortEntry .1.3.6.1.4.1.9.9.402.1.2 |
cpeExtPsePortEntryA cpeExtPsePortEntry extends a corresponding
pethPsePortTable entry. This entry displays and
controls more characteristics of a power Ethernet
port on a PSE device. CpeExtPsePortEntry .1.3.6.1.4.1.9.9.402.1.2.1 |
cpeExtPsePortEnableThis object is an extension of the pethPsePortAdminEnable
object from RFC3621. It allows the user to be more specific
when enabling the PSE functions. The states, 'auto', 'static'
and 'limit' correspond to a value of 'true' for the
pethPsePortAdminEnable object. The state 'disable' corresponds
to a value of 'false' for the pethPsePortAdminEnable object.
Setting this value to 'auto' enables Powered Device discovery
on the interface and the amount of power allocated depends on
the Powered Device discovered. If pethPsePortAdminEnable was
'false' prior to this set operation, then it will become
'true'.
Setting this value to 'static' will also enable Powered
Device discovery. However, this is different from 'auto'
in that the amount of power is pre-allocated based on the
configuration on the Power Sourcing Equipment. If
pethPsePortAdminEnable was 'false' prior to this set
operation, then it will become 'true'.
Setting this value to 'limit' enables Powered Device
discovery on the interface. The amount of power allocated
depends on the Powered Device discovered and the value
of cpeExtPsePortPwrMax. The lower value will be used.
If pethPsePortAdminEnable was 'false' prior to this set
operation, then it will become 'true'.
Setting this value to 'disable' disables the PSE functions.
The pethPsePortAdminEnable object will adopt the value of
'false' if it was 'true' prior to this set operation. When
setting the pethPsePortAdminEnable object to 'false' this
object cpeExtPsePortEnable will adopt the value of 'disable'.
If cpeExtPsePortPolicingCapable of the PSE port, or
cpeExtMainPsePwrMonitorCapable of the PSE port's
main group, has the value of 'false', this object
can only be set to 'auto', 'static' or 'disable'.
Otherwise, this object can be set to 'auto', 'static',
'limit' or 'disable'.rw Enumeration .1.3.6.1.4.1.9.9.402.1.2.1.1 |

interface is IEEE based.
A value of 'cisco' indicates that the discover mode on the
interface is Cisco based.
A value of 'ieeeAndCisco' indicates that the discover mode on
the interface is both IEEE and Cisco based.ro Enumeration .1.3.6.1.4.1.9.9.402.1.2.1.2 |

the interface.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.402.1.2.1.3 |
cpeExtPsePortIeeePdThis object indicates whether the Powered Device attached
to the interface is an IEEE compliant Powered Device or not.
A value of 'true' indicates the attached Powered Device is
an IEEE compliant Powered Device.
A value of 'false' indicates the attached Powered Device
is not an IEEE compliant Powered Device. This also means
that the value of the corresponding object from the
pethPsePortTable, pethPsePortPowerClassifications is
irrelevant.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.402.1.2.1.4 |
cpeExtPsePortAdditionalStatusThis object is an extension of the pethPsePortDetectionStatus

being denied power because the PD is trying
to consume more power than it has been
configured to consume.
overdrawLog: When set, the PD attached to the interface
is trying to consume more power than it has
been configured to consume, but is not being
denied power.ro Bits .1.3.6.1.4.1.9.9.402.1.2.1.5 |

cpeExtPsePortPolicingActionThis object specifies the power policing action that
the device will take on this PSE port when the real-time

cpeExtPsePortPwrManAllocThis object specifies the manual power allocation that
the PSE will allocate to the PD connected to this
interface regardless of the amount requested via CDP
or IEEE.
Setting this object value to zero disables the manual
power allocation.

cause damage to the system and void the warranty. Take
precautions not to oversubscribe the power supply.rw Unsigned32 UNITS "milliwatts" .1.3.6.1.4.1.9.9.402.1.2.1.15 |
cpeExtPsePortCapabilitiesThis object indicates the PSE functionality that
this port supports.
If the 'policing' BIT is set, then this PSE port is
capable of policing the port for proper power consumption
based on the allocated value.
If the 'poePlus' BIT is set, then this PSE port supports
PoE Plus functions.ro Bits .1.3.6.1.4.1.9.9.402.1.2.1.16 |
