Field Name Field Description
Output errors on the interface. The following paragraphs explain the counters
Output errors
whose meaning might not be obvious:
Carrier transitions
This number does not normally increment quickly, increasing only when the
cable is unplugged, the far-end system is powered down and then up, or
another problem occurs. If the number of carrier transitions increments quickly
(perhaps once every 10 seconds), the cable, the far-end system, or the PIC
or PIM is malfunctioning.
Errors
Drops
ASIC. If the interface is saturated, this number increments once for every
packet that is dropped by the ASIC's RED mechanism.
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.
Aged packets
so long that the system automatically purged them. The value in this field
should never increment. If it does, it is most likely a software bug or possibly
malfunctioning hardware.
FIFO errors
ASIC on the PIC. If this value is ever nonzero, the PIC is probably
malfunctioning.
HS link CRC errors
ASICs responsible for handling the switch interfaces.
MTU errors
Resource errors
Total number of egress queues supported on the specified interface.
Egress queues
CoS queue number and its associated user-configured forwarding class name.
Queue counters
(Egress )
Queued packets
Transmitted packets
Dropped packets
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.
