packets can be passed.ro Enumeration .1.3.6.1.4.1.333.2.1.2.3.1.11 |
cnt2XIfLastChangeThe value of sysUpTime at the time the interface
entered its current operational state. If the
current state was entered prior to the last re-
initialization of the local network management
subsystem, then this object contains a zero
value.ro TimeTicks (SNMPv2-SMI) .1.3.6.1.4.1.333.2.1.2.3.1.12 |
cnt2XIfLinkUpDownTrapEnableIndicates whether linkUp/linkDown traps should be
generated for this interface.
By default, this object should have the value
enabled(1) for interfaces which do not operate on
'top' of any other interface (as defined in the
ifStackTable), and disabled(2) otherwise.rw Enumeration .1.3.6.1.4.1.333.2.1.2.3.1.13 |
cnt2XIfPromiscuousModeThis object has a value of false(2) if this interface
only accepts packets/frames that are addressed to this
station. This object has a value of true(1) when the
station accepts all packets/frames transmitted on the
media. The value true(1) is only legal on certain
types of media. If legal, setting this object to a
value of true(1) may require the interface to be reset
before becoming effective.
The value of ifPromiscuousMode does not affect the
reception of broadcast and multicast packets/frames by
the interface.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.333.2.1.2.3.1.14 |
cnt2XIfConnectorTypeThis object has the value 'true(1)' if the interface
sublayer has a physical connector and the value
'false(2)' otherwise.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.333.2.1.2.3.1.15 |
cnt2XIfAliasThis object is an 'alias' name for the interface as
specified by a network manager, and provides a non-
volatile 'handle' for the interface.
On the first instantiation of an interface, the value
of ifAlias associated with that interface is the
zero-length string. As and when a value is written
into an instance of ifAlias through a network
management set operation, then the agent must retain
the supplied value in the ifAlias instance associated
with the same interface for as long as that interface
remains instantiated, including across all re-
initializations/reboots of the network management
system, including those which result in a change of
the interface's ifIndex value.
An example of the value which a network manager might
store in this object for a WAN interface is the
(Telco's) circuit number/identifier of the interface.
Some agents may support write-access only for
interfaces having particular values of ifType. An
agent which supports write access to this object is
required to keep the value in non-volatile storage,
but it may limit the length of new values depending on
how much storage is already occupied by the current
values for other interfaces.rw DisplayString .1.3.6.1.4.1.333.2.1.2.3.1.16 |
cnt2XIfInOctetsThe total number of octets received on the
interface, including framing characters.ro Counter64 .1.3.6.1.4.1.333.2.1.2.3.1.17 |

delivered to a higher-layer protocol.ro Counter32 .1.3.6.1.4.1.333.2.1.2.3.1.18 |
cnt2XIfInMulticastPktsThe number of packets, delivered by this sub-layer to
a higher (sub-)layer, which were addressed to a
multicast address at this sub-layer. For a MAC layer
protocol, this includes both Group and Functional
addresses.

addressed to a broadcast address at this sub-layer,
