1.3.6.1.2.1.2.2.1.1

ifIndex

INTEGER

read-only

A unique value for each interface. Its value

ranges between 1 and the value of ifNumber. The

value for each interface must remain constant at

least from one re-initialization of the entity's

network management system to the next re-

initialization.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.2.2.1.2

ifDescr

OCTET STRING{(0,255)}

read-only

A textual string containing information about the

interface. This string should include the name of

the manufacturer, the product name and the version

of the hardware interface.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.2.2.1.3

ifType

INTEGER{other(1),regular1822(2),hdh1822(3),ddn-x25(4),rfc877-x25(5),ethernet-csmacd(6),iso88023-csmacd(7),iso88024-tokenBus(8),iso88025-tokenRing(9),iso88026-man(10),starLan(11),proteon-10Mbit(12),proteon-80Mbit(13),hyperchannel(14),fddi(15),lapb(16),sdlc(17),ds1(18),e1(19),basicISDN(20),primaryISDN(21),propPointToPointSerial(22),ppp(23),softwareLoopback(24),eon(25),ethernet-3Mbit(26),nsip(27),slip(28),ultra(29),ds3(30),sip(31),frame-relay(32)}

read-only

The type of interface, distinguished according to

the physical/link protocol(s) immediately `below'

the network layer in the protocol stack.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.2.2.1.4

ifMtu

INTEGER

read-only

The size of the largest datagram which can be

sent/received on the interface, specified in

octets. For interfaces that are used for

transmitting network datagrams, this is the size

of the largest network datagram that can be sent

on the interface.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.2.2.1.5

ifSpeed

INTEGER{(0,4294967295)}

read-only

An estimate of the interface's current bandwidth

in bits per second. For interfaces which do not

vary in bandwidth or for those where no accurate

estimation can be made, this object should contain

the nominal bandwidth.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.2.2.1.6

ifPhysAddress

OCTET STRING

read-only

The interface's address at the protocol layer

immediately `below' the network layer in the

protocol stack. For interfaces which do not have

such an address (e.g., a serial line), this object

should contain an octet string of zero length.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.2.2.1.7

ifAdminStatus

INTEGER{up(1),down(2),testing(3)}

read-write

The desired state of the interface. The

testing(3) state indicates that no operational

packets can be passed.

The actually supported value range is 1|2.

1.3.6.1.2.1.2.2.1.8

ifOperStatus

INTEGER{up(1),down(2),testing(3),unknown(4),dormant(5),notPresent(6),lowerLayerDown(7)}

read-only

The current operational state of the interface.

The testing(3) state indicates that no operational

packets can be passed. If ifAdminStatus is down(2) then

ifOperStatus should be down(2). If ifAdminStatus is

changed to up(1) then ifOperStatus should change to

up(1) if the interface is ready to transmit and

receive network traffic; it should change to

dormant(5) if the interface is waiting for external

actions (such as a serial line waiting for an incoming

connection); it should remain in the down(2) state if

and only if there is a fault that prevents it from

going to the up(1) state; it should remain in the

notPresent(6) state if the interface has missing

(typically, hardware) components.

The actually supported value range is up(1);down(2).

1.3.6.1.2.1.2.2.1.9

ifLastChange

TimeTicks

read-only

The 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.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.2.2.1.10

ifInOctets

INTEGER{(0,4294967295)}

read-only

The total number of octets received on the

interface, including framing characters.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.2.2.1.11

ifInUcastPkts

INTEGER{(0,4294967295)}

read-only

The number of subnetwork-unicast packets

delivered to a higher-layer protocol.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.2.2.1.12

1.3.6.1.2.1.2.2.1.13

ifInDiscards

INTEGER{(0,4294967295)}

read-only

The number of inbound packets which were chosen

to be discarded even though no errors had been

detected to prevent their being deliverable to a

higher-layer protocol. One possible reason for

discarding such a packet could be to free up

buffer space.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.2.2.1.14

unicast (i.e., a subnetwork-broadcast or

subnetwork-multicast) address, including those

that were discarded or not sent.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.2.2.1.19

ifOutDiscards

INTEGER{(0,4294967295)}

read-only

The number of outbound packets which were chosen

to be discarded even though no errors had been

detected to prevent their being transmitted. One

possible reason for discarding such a packet could

be to free up buffer space.

1.3.6.1.2.1.2.2.1.20

ifOutErrors

1.3.6.1.2.1.2.2.1.22

ifSpecific

OBJECT IDENTIFIER

read-only

A reference to MIB definitions specific to the

particular media being used to realize the

interface. For example, if the interface is

realized by an ethernet, then the value of this

object refers to a document defining objects

specific to ethernet. If this information is not

present, its value should be set to the OBJECT

IDENTIFIER { 0 0 }, which is a syntatically valid

object identifier, and any conformant

implementation of ASN.1 and BER must be able to

generate and recognize this value.

This object is implemented as defined in the corresponding MIB files.
