Field Name Field Description
The sample statistics taken at the specified interval.
Sample Index
Drop Events
Manager ASIC. If the interface is saturated, this number increments once for
every packet that is dropped by the ASIC's RED mechanism.
Octets
the received octets count varies by interface type.
Packets
Broadcast Packets
Multicast Packets
CRC errors
framing bits, but including FCS octets) of between 64 and 1518 octets,
inclusive, and had either a bad FCS with an integral number of octets (FCS
error) or a bad FCS with a nonintegral number of octets (alignment error).
Undersize Pkts
that were less than 64 octets long (excluding framing bits but including FCS
octets) and were otherwise well formed.
Oversize Pkts
were longer than 1518 octets (excluding framing bits, but including FCS octets)
but were otherwise well formed.
Fragments
(excluding framing bits, but including FCS octets), and had either an FCS
error or an alignment error. Fragment frames normally increment because
both runts (which are normal occurrences caused by collisions) and noise
hits are counted.
Jabbers
framing bits, but including FCS octets), and had either an FCS error or an
alignment error. This definition of jabber is different from the definition in
IEEE-802.3 section 8.2.1.5 (10BASE5) and section 10.3.1.4 (10BASE2). These
documents define jabber as the condition in which any packet exceeds 20
ms. The allowed range to detect jabber is from 20 ms to 150 ms.
Collisions
only full-duplex operation, so for Gigabit Ethernet PICs, this number should
always remain 0. If it is nonzero, there is a software bug.
Utilization(%)
utilization on this interface during this sampling interval, in hundredths of a
percent.
