This group provides the number of interfaces on a managed device and a table describing
all interfaces.
The ifNumber OID is the number of network interfaces present on this system. On a
CDM-IP300L the ifNumber should be 3 corresponding to the Ethernet, Satellite, and
Loopback interfaces.

OID Description
ifIndex Unique value for each interface. The CDM-IP300L gives the
Satellite (hdl0), Loopback (lo0), and Ethernet (fei0) interfaces
values of 1, 2, or 3 respectively.
ifDescr Textual string containing information about the interface. The
Ethernet interface is “fei0”. The Loopback interface is “lo0”. The
Satellite interface is “hdl0”.
ifType Link protocol for the interface. The Ethernet interface is set to
ethernetCsmacd(6). The Loopback interface is set to
softwareLoopback(24). The Satellite Interface is
propPointToPointSerial(22).
ifMtu Size of the largest datagram which can be sent/received on the
interface, specified in octets. For the Ethernet and Satellite
Interfaces, the MTU is 1500.
ifSpeed Estimate of the interface's current bandwidth in bits per second.
The Ethernet Interface can be set to either 100000000 (100 Mbps)
or 10000000 (10 Mbps). If the Ethernet driver is set to “Auto” then
100000000 will be returned. The Satellite Interface’s ifSpeed
corresponds to the data rate of the transmitter only. The
transmitter’s ifSpeed can range from 2400 (2.4 Kbps) to 2048000
(2.048 Mbps). If the CDM-IP300L is a Demod-Only then ifSpeed
will be zero.
ifPhyAddress Interface's address at the datalink layer. For the Ethernet Interface
this corresponds to the MAC address (6 bytes). For the Satellite
and Loopback Interface this value is undefined.
ifAdminState Desired state of the interface. For the CDM-IP300L, the interfaces
cannot be changed from an up(1) status.
ifOperState Current operational state of the interface. For the CDM-IP300L,
the interfaces will remain in an up(1) status.
ifLastChange Value of sysUpTime at the time the interface entered its current
operational state. For the CDM-IP300L, this will remain zero,
corresponding to boot time.
ifInOctets Total number of octets received on the interface. This statistic is
counted for Satellite interface only.
