10 GigaBit iBypass Switch with Heartbeat

Field

Description

Total Bytes

Total number of bytes that have passed through the iBypass
unit since the last reset.

When this value changes, a circled

arrow appears next to the value to alert you to the change;

if polling produces the same byte total twice in a row, the
circled arrow disappears.

Oversized Packets

This function tracks the number of oversized packets since

the last reset. The Ethernet specification requires that no

packet be larger than 151 bytes (including checksum).

Any packet that is larger than this is flagged as an error and

discarded. These packets are also sometimes referred to
as “Jabbers”. Packets too big are almost always caused by
faulty hardware. The network adapter card on a link showing
a high rate of oversized packets should be replaced. Sup-
port IEEE 0.1q

CRC Packets

This function tracks the number of CRC errors since the last
reset. MAC Frame CRC errors are the most common. Ether-
net packets are encapsulated in a MAC frame that contains
a preamble, and a post-envelope CRC check. The Ethernet
adapter on the sending station creates the preamble, inserts
the packet data (addressing, protocol, data, etc.), calculates
a CRC checksum and inserts it at the end of the packet. If
the receiving station determines that the checksum is incor-
rect, the packet is assumed to be bogus and is discarded.

MAC frame CRC errors are typically caused by faulty
cabling. If the cabling connecting an Ethernet Adapter or
hub is faulty, the electric connection may be on and off
many times during a transmission. This on-and-off state can
interrupt parts of a transmission and damage the signal. If
the signal is interrupted partially during transmission, the
CRC checksum that was calculated by the network adapter

is longer valid and the packet is flagged as a CRC error and

discarded.

CRC errors are common on a busy network, and a small

percentage does not reflect a network problem. When the

percentage is large, or when a single station shows a larger
percent CRC errors, there is probably a problem.
