Interfaces Group (Windows Embedded CE 6.0)

1/6/2010

The Interfaces Group contains information about the physical interfaces of the entity, such as information about the events that take place at each interface. Each interface is considered attached to a subnetwork. You must implement the Interfaces Group for all of the systems. The following table shows the variables of the Interfaces Group and their properties.

Name Type Access Description

ifNumber

Integer

R/O

Number of network interfaces on system

ifTable

 

 

Contains information on each network interface

ifIndex

Integer

R/O

Index of interface (1 to ifNumber); Windows Embedded CE does not support the InterfaceIndex member variable

ifDescr

Octet string

R/O

Description of the interface

ifType

Integer

R/O

Type of interface: 6 = Ethernet23 = PPP24 = loopback

ifMtu

Integer

R/O

Maximum datagram size for the interface

ifSpeed

Gauge

R/O

Interface speed (in bits per second)

ifPhysAddress

Octet string

R/O

Physical address (media access control address) of the interface

ifAdminStatus

Integer

R/O

Expected interface state: 1 = up2 = down3 = testing

ifOperStatus

Integer

R/O

Current interface state: 1 = up2 = down3 = testing

ifLastChange

TimeTicks

R/O

Last time that the state changed (from sysUpTime)

ifInOctets

Counter

R/O

Total bytes that are received, including framing characters

ifInUcastPkts

Counter

R/O

Number of unicast packets that are delivered to a higher layer

ifInNUcastPkts

Counter

R/O

Number of non-unicast packets that are delivered to a higher layer

ifInDiscards

Counter

R/O

Inbound packets that are discarded without known errors

ifInErrors

Counter

R/O

Inbound packets that are discarded because of errors

ifInUnknownProtos

Counter

R/O

Inbound packets that are discarded because of an unknown protocol

ifOutOctets

Counter

R/O

ifOutUcastPkts

Counter

R/O
