Viewing port statistics
For each port (except V-Line ports) the system provides details for the total number of bytes sent and received, port
utilization percentages, undersized and fragmented packet errors, and other statistical information. For SFP ports, the
system also provides transceiver and physical link information.
For V-Line ports the system provides a limited set of statistics that comprises packet (not octets) counts only and no error
statistics.
Viewing traffic statistics
The Traffic tab shows accumulated packet statistics for the selected port(s) since the last reboot or counter reset.

Viewing errors statistics
The Errors tab shows various accumulated packet errors since the last reboot or counter reset.
Statistics for the following packet errors are available:
•
Undersize
—Number of undersized packets (less than 64 octets) received.
•
Fragments
—Number of fragments (packets with less than 64 octets, excluding framing bits, but including FCS octets)
received.
•
Oversize
—Number of packets over the MRU size received.
•
Jabber
—Total number of received packets that were longer than the MRU. 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
•
Rx Error
—Number of transmission errors received.
•
FCS Error
—Number of frame checksum errors received.
