Field Name Field Description
Ethernet-specific defects that can prevent the interface from passing packets.
Active alarms and
When a defect persists for a certain amount of time, it is promoted to an alarm.
Active defects
Based on the switch configuration, an alarm can ring the red or yellow alarm
bell on the switch or turn on the red or yellow alarm LED on the front of the
switch. These fields can contain the value
None
—Interface has lost its link state, which usually means that the cable is
Link
unplugged, the far-end system has been turned off, or the PIC is
malfunctioning.
MAC statistics Receive
Total octets
Unicast packets, Broadcast packets,
broadcast, and multicast packets.
CRC/Align errors
(excluding 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).
FIFO error
If this value is ever nonzero, the PIC is probably malfunctioning.
MAC control frames

Oversized frames
Jabber frames
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.
Fragment frames
length (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.
Code violations
reception error" or "invalid data symbol error."
Information about the configuration of the Packet Forwarding Engine:
Packet Forwarding
Engine
Destination slot
configuration
On standalone switches with built-in interfaces, the slot number refers to
the switch itself and is always 0.
On Virtual Chassis composed of switches with built-in interfaces, the slot
number refers to the member ID of the switch.
On switches with line cards or on Virtual Chassis composed of switches
with line cards, the slot number refers to the line card slot number on the
switch or Virtual Chassis.
