Operational Status - The state of the interface. The testing state indicates that no operational packets can be
passed. Up - ready to pass packets; Down - cannot pass packets; testing - in some test mode.
Output queue length - The total number of octets (bytes) waiting to be transmitted via this interface.
Out errors - The number of outbound packets that contained errors preventing them from being transmitted
via this interface.
Out non-unicast packets - The total number of packets that higher-layer protocols requested be transmitted
to a non-unicast (i.e. a subnetwork-broadcast or subnetwork-multicast) address, including those that were
discarded or not sent.
Out unicast packets - The total number of packets that higher-layer protocols requested be transmitted to a
subnetwork-unicast address, including those that were discarded or not sent.
Out octets(bytes) - The total number of octets (bytes) transmitted out of the interface, including framing
characters.
Unknown protocols - The number of packets received via the interface which were discarded because of an
unknown or unsupported protocol.
In errors - The number of inbound packets that contained errors preventing them from being deliverable to a
higher-layer protocol.
In discards - The number of inbound packets to which were chosen to be discarded even they were deliver-
able to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer
space.
In non-unicast packets - The number of non-unicast (i.e., subnetwork-broadcast or subnetwork-multicast)
packets delivered to a higher-layer protocol.
In unicast packets - The number of subnetwork-unicast packets delivered to a higher-layer protocol.
In octets (bytes) - The total number of octets (bytes) received on the interface, including framing characters.
Max packet size - The size of the largest datagram which can be sent/received on the interface, specified in
octets. For interfaces used for transmitting network datagrams, this is the size of the largest network datagram
that can be sent on the interface.
Speed - An estimate of the interface’s current bandwidth in bits per second. For interfaces which do not vary
in bandwidth or whose bandwidth can’t be accurately estimated, this object should contain the nominal band-
width.
Admin Status - The desired state of the interface. The testing state indicates that no operational packets can
be passed.
Last Change - The value of sysUpTime at the time the interface entered its current operational state. If the
current state was entered prior to the last reinitialization of the local network-managment subsystem, then this
object contains a value of zero.
