Table 182: show interfaces xe- Output Fields (continued)
Level of Output Field Description Field Name
detail
extensive
none
Ethernet-specific defects that can prevent the interface from passing packets.
When a defect persists for a certain amount of time, it is promoted to an alarm.
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 or Link .
• None —There are no active defects or alarms.
•
Link
—Interface has lost its link state, which usually means that the cable is
unplugged, the far-end system has been turned off, or the PIC is
malfunctioning.
Active alarms and
Active defects
extensive Receive and Transmit statistics reported by the PIC's MAC subsystem.
•
Total octets
and
total packets
—Total number of octets and packets.
•
Unicast packets, Broadcast packets,
and
Multicast packets
—Number of
unicast, broadcast, and multicast packets.
•
CRC/Align errors
—Total number of packets received that had a length
(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 —Number of FIFO errors that are reported by the ASIC on the PIC.
If this value is ever nonzero, the PIC is probably malfunctioning.
•
MAC control frames
—Number of MAC control frames.
•
MAC pause frames
—Number of MAC control frames with
pause
operational
code.
• Oversized frames —Number of frames that exceed 1518 octets.
•
Jabber frames —Number of frames that were longer than 1518 octets
(excluding 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
—Total number of packets that were less than 64 octets in
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
—Number of times an event caused the PHY to indicate “Data
reception error” or “invalid data symbol error.”

Information about the configuration of the Packet Forwarding Engine:
•
Destination slot
—FPC slot number.
NOTE: For an EX2200, EX3200, or EX4500 switch, or an EX4200 standalone
switch, the FPC slot number refers to the switch itself and is always
0
. In a Virtual
Chassis configuration, the FPC slot number refers to the member ID. In an
EX8200 switch, the FPC slot number refers to the line card slot number.
