seconds.
■ 30 Sec — Indicates that the port statistics are refreshed every 30
seconds.
■ 60 Sec — Indicates that the port statistics are refreshed every 60
seconds.
■ Received Bytes (Octets) — Displays the number of octets received
on the interface since the device was last refreshed. This number
includes bad packets and FCS octets, but excludes framing bits.
■ Received Packets — Displays the number of packets received on the
interface, including bad packets, Multicast and broadcast packets,

■ Undersize Packets — Displays the number of undersized packets
(less than 64 octets) received on the interface since the device was last

■ Oversize Packets — Displays the number of oversized packets (over
1522 octets) received on the interface since the device was last

■ Fragments — Displays the number of fragments (packets with less
than 64 octets, excluding framing bits, but including FCS octets)
received on the interface since the device was last refreshed.
■ Jabbers — Displays the total number of received packets that were
longer than 1522 octets. This number excludes frame bits, but includes
FCS octets that had either a bad Frame Check Sequence (FCS) with an
integral number of octets (FCS Error) or a bad FCS with a non-integral
