IF-MIB

DESCRIPTION

The size of the largest packet 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.

::= {ifEntry 4}

ifSpeed OBJECT-TYPE

SYNTAX Gauge32

MAX-ACCESS read-only

STATUS current

DESCRIPTION

An estimate of the interface 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. If the bandwidth of the interface is greater than the maximum value reportable

by this object then this object should report its maximum value (4,294,967,295) and ifHighSpeed

must be used to report the interface speed. For a sub-layer which has no concept of bandwidth, this

object should be zero.

::= {ifEntry 5}

ifPhysAddress OBJECT-TYPE

SYNTAX PhysAddress

MAX-ACCESS read-only

STATUS current

DESCRIPTION

The interface's address at its protocol sub-layer. For example, for an 802.x interface, this object

normally contains a MAC address. The interface's media-specific MIB must define the bit and byte

ordering and the format of the value of this object. For interfaces which do not have such an address

(e.g., a serial line), this object should contain an octet string of zero length.

::= {ifEntry 6}

ifAdminStatus OBJECT-TYPE

SYNTAX Integer {up(1), -- ready to pass packets down(2), testing(3) -- in some test mode}

MAX-ACCESS read-write

STATUS current

DESCRIPTION

The desired state of the interface. The testing(3) state indicates that no operational packets can be

passed. When a managed system initializes, all interfaces start with ifAdminStatus in the down(2)

state. As a result of either explicit management action or per configuration information retained by

the managed system, ifAdminStatus is then changed to either the up(1) or testing(3) states (or

remains in the down(2) state).

::= {if Entry 7}

ifOperStatus OBJECT-TYPE

SYNTAX INTEGER {up(1),-- ready to pass packets down(2), testing(3), -- in some test mode

unknown(4), -- status can not be determined -- for some reason. dormant(5), notPresent(6),-- some

component is missing lowerLayerDown(7) -- down due to state of -- lower-layer interface(s)}
