Table 58 MIB-II Interface List Table MIB
MIB Name OID Type Status Description
ifIndex 1 Integer R The number of entries in ifTable.
ifTable 2 MIB The list of interfaces.
MIB Name OID Value Type Accepted Values Description
ifIndex 1 Integer 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.
ifDescr 2 String lo0: loopback
esmc0: ethernet
mdr1: radio
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.
ifType 3 Integer 6:ethernet-csmacd
6: radio interface
24: softwareLoopback
The type of interface, distinguished
according to the physical/link protocol(s)
immediately `below' the network layer in
the protocol stack. The radio interface
and ethernet-csmacd return the same
value since they are both viewed as
Ethernet ports by the CCU routing
application.
ifMtu 4 Integer 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.
ifSpeed 5 Gauge 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.
