System information

RMON Modes 423
integral number of octets (FCS Error) or a bad FCS with a non-integral number of octets
(Alignment Error).
Note: It is entirely normal for etherStatsFragments to increment. This is
because it counts both runts (which are normal occurrences due to
collisions) and noise hits.
Jabbers
The number of packets received that were longer than 1518 octets (excluding framing bits,
but including FCS octets), and had either a bad Frame Check Sequence (FCS) with an
integral number of octets (FCS Error) or a bad FCS with a non-integral number of octets
(Alignment Error).
Note: This definition of jabber is different than the definition in IEEE-802.3
section 8.2.1.5 (10BASE5) and section 10.3.1.4 (10BASE2). These
documents define jabber as the condition where any packet exceeds 20 ms.
The allowed range to detect jabber is between 20 ms and 150 ms.
Multicast Packets
The number of good packets received that were directed to a multicast address. Note that
this number does not include packets directed to the broadcast address.
Occurrence of Hardware Address
The occurrence of a hardware address specified in the Actions dialog. The addresses are
listed from the local or remote address table. This table can be viewed or edited in either
the “Discover Network Names” mode dialog, or the “Filter” dialog.
Note: This trigger is only available using Network Instruments’ RMON2
Probe.
Oversized Packets
The number of packets received that were longer than 1518 octets (excluding framing bits,
but including FCS octets) and were otherwise well formed.
Packets
The number of packets (including bad packets, broadcast packets, and multicast packets)
received.
Sequence of Bytes at an Offset
The occurrence of a sequence of bytes at a specified offset. The format of the offset is a
decimal number representing the number of bytes “offset” or from the beginning of a
packet. The bytes defined must be defined in hex with a space between each set of
characters.
