Interface Monitor
The interfaces table contains information on the unit’s interfaces. Each interface is thought of as being attached
to a ‘subnetwork’. Note that this term should not be confused with ‘subnet’ which refers to an address-
partitioning scheme used in the Internet suite of protocols.
Type - The type of interface, distinguished according to the physical-link protocols immediately below the
network layer in the protocol stack. The possible types are: other, regular1822, hdh1822, ddn-x25, rfc877-
x25, ethernet-csmacd, iso88023-csmacd, iso80024-tokenbus, iso88025-tokenring, iso99026-man, starLan,
proteon-10Mbit, proteon-80Mbit, hyperchannel, fddi, lapb, sdlc, ds1, e1, basicISDN, PrimaryISDN,
propPointToPointSerial, ppp, softwareloopback, eon, ethernet-3Mbit, nsip, slip, ultra, ds3, sip, frame-relay.
Description - 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.
MIB specific definator - A reference to MIB definitions specific to the particular media being used to
realize the interface. For example, if the interface is being realized by an Ethernet, then the value of this object
refers to a document defining objects specific to the Ethernet. If this information is not present, its value will be
set to 0.
Physical Address - 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.
