inoctetscountField
How many octets were received on the interface, including those that
deliver framing information.
Intel
A registered trademark of Intel Corporation.
inucastpktscountField
How many inbound subnetwork-unicast packets were delivered to a
higher-layer protocol.
inunknownprotoscount
Field
How many inbound packets were discarded because of an unknown
or unsupported protocol.
IP
Internet Protocol defined in RFC 791. The Network Layer in the
TCP/IP protocol stack. This protocol is applied to addressing, routing,
and delivering, and re-assembling data packets into the Data Link
layer of the protocol stack. See
http://www.faqs.org/rfcs/rfc791.html
.
IPAddress
32-bit binary number that identifies a network element by both network
and host. See also Subnet Mask.
IPv4
Traditional version of Internet Protocol, which defines 32-bit fields for
data transmission.
ISM
Industrial, Scientific, and Medical Equipment radio frequency band, in
the 900-MHz, 2.4-GHz, and 5.8-GHz ranges.
Jitter
Timing-based measure of the reception quality of a link. An acceptable
link displays a jitter value between 0 and 4 for a 10-Mbps Backhaul
timing slave in Release 4.0 and later, 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.
L2TPoverIPSec
Level 2 Tunneling Protocol over IP Security. One of several virtual
private network (VPN) implementation schemes. Regardless of
whether Subscriber Modules have the Network Address Translation
feature (NAT) enabled, they support VPNs that are based on this
protocol.
LateCollisionField
This field displays how many late collisions occurred on the Ethernet
controller. A normal collision occurs during the first 512 bits of the
frame transmission. A collision that occurs after the first 512 bits is
considered a late collision. A late collision is a serious network
problem because the frame being transmitted is discarded. A late
collision is most commonly caused by a mismatch between duplex
configurations at the ends of a link segment.
LatencyTolerance
Acceptable tolerance for delay in the transfer of data to and from a
module.
LineofSight
Wireless path (not simply visual path) direct from module to module.
The path that results provides both ideal aim and an ideal Fresnel
zone.
Linux
