The statistics are displayed for the selected interface.
• Bytes Received (Octets)—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 good packets received, including Multicast
and Broadcast packets.
• Broadcast Packets Received—Number of good Broadcast packets
received. This number does not include Multicast packets.
• Multicast Packets Received—Number of good Multicast packets received.
• CRC & Align Errors—Number of CRC and Align errors that have occurred.
• Undersize Packets—Number of undersized packets (less 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—Total number 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.
• Frames of 64 Bytes—Number of frames, containing 64 bytes that were
received.
• Frames of 65 to 127 Bytes—Number of frames, containing 65-127 bytes
that were received.
