Description
Port
The port for the RMON statistics.
Bytes Received
Number of octets received, including bad packets and FCS octets,
but excluding framing bits.
Drop Events
Number of packets that were dropped.
Packets Received
Number of packets received, including bad packets, Multicast
packets, and Broadcast packets.
Broadcast Packets
Number of good Broadcast packets received. This number does not
include Multicast packets.
Multicast Packets
Number of good Multicast packets received.
CRC &Align Errors
Number of CRC and Align errors that have occurred.
Undersize Packets
Number of undersized packets (les than 64 octets) received.
Oversize Packets
Number of oversized packets (over 1518 octets) received.
Fragments
Number of fragments (packets with less than 64 octets, excluding
framing bits, but including FCS octets) received.
Jabbers
Number of received packets that were longer than 1632 octets. This
number excludes frame bits, but includes FCS octets that had either
a bad FCS (Frame Check Sequence) with an integral number of
octets (FCS Error) or a bad FCS with a non-integral octet
(Alignment Error) number. A Jabber packet is defined as an
Ethernet frame that satisfies the following criteria:
•
Packet data length is greater than MRU.
•
Packet has an invalid CRC.
•
RX error event has not been detected.
Collisions
Number of collisions received. If Jumbo Frames are enabled, the
threshold of Jabber Frames is raised to the maximum size of Jumbo
Frames.
