physical interface which were dropped as
they were larger than the ifMtu (largest
permitted  size of a packet which can be
sent/received on an interface).
Discontinuities in the value of this variable
can occur at re-initialization of the
management system, and at other times as
indicated by the values of
cieIfPacketDiscontinuityTime.
cieIfInFramingErrs.1.3.6.1.4.1.9.9.276.1.1.1.1.6

The number of input packets which arrived
on a particular physical interface which
were too quick for the hardware to receive
and hence the receiver ran out of buffers.

can occur at re-initialization of the
management system, and at other times as
indicated by the values of
cieIfPacketDiscontinuityTime.
cieIfInIgnored.1.3.6.1.4.1.9.9.276.1.1.1.1.8
The number of input packets which were simply
ignored by this physical interface due to
insufficient resources to handle the incoming

can occur at re-initialization of the
management system, and at other times as
indicated by the values of
cieIfPacketDiscontinuityTime.
cieIfInAbortErrs.1.3.6.1.4.1.9.9.276.1.1.1.1.9

management system, and at other times as
indicated by the values of
cieIfPacketDiscontinuityTime.

no error had been detected to prevent them
being transmitted.
The packet could be dropped for many reasons,
which could range from the interface being

Discontinuities in the value of this variable
can occur at re-initialization of the
management system, and at other times as
indicated by the values of
cieIfPacketDiscontinuityTime.

The value of sysUpTime on the most recent
occasion at which this interface's  counters
suffered  a discontinuity.
If no such discontinuities have occurred
since the last re-initialization of the
local management subsystem, then this
object contains a value of zero.
cieIfResetCount.1.3.6.1.4.1.9.9.276.1.1.2.1.1
The number of times the interface was
internally reset and brought up.
Some of the actions which can cause this
counter to increment are :
o  Bringing an interface up using the
interface CLI command.
o  Clearing the interface with the exec
CLI command.
o  Bringing the interface up via SNMP.
Discontinuities in the value of this variable
can occur at re-initialization of the
management system, and at other times as
indicated by the values of
cieIfInterfaceDiscontinuityTime.
cieIfKeepAliveEnabled.1.3.6.1.4.1.9.9.276.1.1.2.1.2
A keepalive is a small, layer-2 message
that is transmitted by a network device
to let directly-connected network devices
know of its presence.
This object returns true(1) if keepalives
are enabled on this interface. If keepalives
are not enabled, false(2) is returned.
Setting this object to TRUE or FALSE enables
or disables (respectively) keepalive on this
interface.
cieIfStateChangeReason.1.3.6.1.4.1.9.9.276.1.1.2.1.3
This object displays a human-readable
textual string which describes the
cause of the last state change of the
interface.

o  'up'
o  'down'
cieIfCarrierTransitionCount.1.3.6.1.4.1.9.9.276.1.1.2.1.4

signal transition.
For example, if a T1 line is unplugged,
then framer will detect the loss of signal
(LOS) on the line  and will count it as a
transition.
Discontinuities in the value of this variable
can occur at re-initialization of the
management system, and at other times as
indicated by the values of
cieIfInterfaceDiscontinuityTime.
cieIfInterfaceDiscontinuityTime.1.3.6.1.4.1.9.9.276.1.1.2.1.5
The value of sysUpTime on the most recent
occasion at which this interface's  counters
suffered  a discontinuity.
If no such discontinuities have occurred
since the last re-initialization of the

object contains a value of zero.
cieIfDhcpMode.1.3.6.1.4.1.9.9.276.1.1.2.1.6
The DHCP mode configured by the
administrator.
If 'true(1)' the DHCP is enabled. In which
case an IP address is requested in DHCP.
This is in addition to any that are
configured by the administrator in
'ciiIPAddressTable' or 'ciiIPIfAddressTable'
in CISCO-IP-IF-MIB.
If 'false(2)' the DHCP is disabled. In which
case all IP addresses are configured by the
administrator in 'ciiIPAddressTable' or
'ciiIPIfAddressTable'.
For interfaces, for which DHCP cannot be or
is not supported, then this object has the
value false(2).
cieIfMtu.1.3.6.1.4.1.9.9.276.1.1.2.1.7
The MTU configured by the administrator.
This object is exactly same as 'ifMtu' in
ifTable from IF-MIB for the same ifIndex
value , except that it is configurable by the
administrator. For more description of this
object refer to 'ifMtu' in IF-MIB.
cieIfContextName.1.3.6.1.4.1.9.9.276.1.1.2.1.8
The ContextName denotes the interface
'context' and is used to logically separate
the MIB management.
RFC 2571 and RFC 2737 describe this approach.
When the agent supports a different SNMP
context, as detailed in RFC 2571 and
RFC 2737, for different interfaces, then the
value of this object specifies the context
name used for this interface.
cieIfOperStatusCause.1.3.6.1.4.1.9.9.276.1.1.2.1.9
This object represents the detailed
operational cause reason for the current
operational state of the interface.
The current operational state of the interface
is given by the 'ifOperStatus' defined
in IF-MIB.
The corresponding instance of
'cieIfOperStatusCauseDescr' must be used to
get the information about the operational
cause value mentioned in this object.
For interfaces whose 'ifOperStatus' is 'down'
the objects 'cieIfOperStatusCause' and
'cieIfOperStatusCauseDescr' together provides
the information about the operational cause
reason and the description of the cause.
The value of this object will be 'none(2)' for
all the 'ifOperStatus' values except for
'down(2)'. Its value will be one status cause
defined in the 'IfOperStatusReason' textual
convention if 'ifOperStatus' is 'down(2)'.
The value of this object will be 'other(1)'
if the operational status cause is not one
defined in 'IfOperStatusReason'.
cieIfOperStatusCauseDescr.1.3.6.1.4.1.9.9.276.1.1.2.1.10
The description for the cause of current
operational state of the interface, given
by the object 'cieIfOperStatusCause'.
For an interface whose 'ifOperStatus' is not
'down' the value of this object will be
'none'.
cieIfStatusListIndex.1.3.6.1.4.1.9.9.276.1.1.3.1.1

zero, which identifies a list of 64 interfaces
within a module.

This object represents the operational mode
for a set of 64 interfaces in the module.
cieInterfacesOperCause.1.3.6.1.4.1.9.9.276.1.1.3.1.4
This object represents the operational status
cause for a set of 64 interfaces in the
module.
cieIfDot1qCustomAdminEtherType.1.3.6.1.4.1.9.9.276.1.3.1.1.1
The Dot1qEtherType allow administrator
to select a non-standard (other than 0x8100)
2-byte ethertype for the interface to
interoperate with third party vendor's system
that do not use the standard 0x8100 ethertype
to identify 802.1q-tagged frames.
The current administrative value of the
802.1q ethertype for the interface.  The
administrative 802.1q ethertype value may
differ from the operational 802.1q ethertype
value.  On some platforms, 802.1q ethertype
may be assigned per group rather than per port.
If multiple ports belong to a port group,
the 802.1q ethertype assigned to any of
the ports in such group will apply to all
ports in the same group.
To configure non-standard dot1q ethertype
is only recommended when the Cisco device
is connected to any third party vendor device.
Also be advised that the custom ethertype value
needs to be changed in the whole cloud of
Cisco device with the same custom ethertype
value if the third party device are separated
by number of Cisco device in the middle.

average of outbound packet rate for this
interface.
cieIfOutOctetRate.1.3.6.1.4.1.9.9.276.1.4.1.1.4

average of outbound octet rate for this
interface.
cieIfDot1dBaseMappingPort.1.3.6.1.4.1.9.9.276.1.5.1.1.1

Represents an interface name mentioned
in the 'ifName' object of this system.
cieIfIndex.1.3.6.1.4.1.9.9.276.1.6.1.1.2
This object represents the 'ifIndex'
corresponding to the interface name mentioned
in the 'cieIfName' object of this instance.
If the 'ifName' mentioned in the 'cieIfName'
object of this instance corresponds to multiple
'ifIndex' values, then the value of this object
