tested. See http://www.faqs.org/rfcs/rfc792.html
.

How many inbound packets were discarded without errors that would
have prevented their delivery to a higher-layer protocol. (Some of
these packets may have been discarded to increase buffer space.)
inerrors count Field
How many inbound packets contained errors that prevented their
delivery to a higher-layer protocol.
innucastpkts count
Field
How many inbound non-unicast (subnetwork-broadcast or
subnetwork-multicast) packets were delivered to a higher-layer
protocol.
inoctets count Field
How many octets were received on the interface, including those that
deliver framing information.
Intel

inucastpkts count Field
How many inbound subnetwork-unicast packets were delivered to a
higher-layer protocol.
inunknownprotos count

link displays a jitter value between 0 and 4 for a 10-Mbps Backhaul
timing slave in Release 4.0 and later releases, between 0 and 9 for a
20-Mbps Backhaul timing slave, or between 5 and 9 for any
Subscriber Module or for a Backhaul timing slave in any earlier
release.
