ifMtu INTEGER R The size of the largest datagram that 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 Gauge R 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.
ifPhysAddress PhysAddress R 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 (for example, a serial
line), this object should contain an octet
string of zero length.
ifAdminStatus INTEGER RW The desired state of the interface. The
testing(3) state indicates that no operational
packets can be passed.
ifOperStatus INTEGER R The current operational state of the interface.
The testing(3) state indicates that no
operational packets can be passed.
ifLastChange TimeTicks R The value of sysUpTime at the time the
interface entered its current operational state.
If the current state was entered prior to the
last re-initialization of the local network
management subsystem, then this object
contains a zero value.
ifInOctets Counter R The total number of octets received on the
interface, including framing characters.
ifInUcastPkts Counter R The number of subnetwork-unicast packets
delivered to a higher-layer protocol.
ifInNUcastPkts Counter R The number of non-unicast (i.e.,
subnetwork-broadcast or
subnetwork-multicast) packets delivered to a
higher-layer protocol.
ifInDiscards Counter R The number of inbound packets which were
chosen to be discarded even though no
errors had been detected to prevent their
being deliverable to a higher-layer protocol.
One possible reason for discarding such a
packet could be to free up buffer space.
