Select the Interface for which Ethernet statistics are to be displayed.
Select the Refresh Rate, the time period that passes before the interface
statistics are refreshed.
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 packets received, including bad packets,
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 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
