Command Line Reference Guide

Line Description
Last clearing... Displays the time when the show interfaces counters
where cleared.
Queuing
strategy...
States the packet queuing strategy. FIFO means first in first
out.
Input Statistics: Displays all the input statistics including:
• Number of packets and bytes into the interface
• Number of packets with VLAN tagged headers
• Packet size and the number of those packets inbound to
the interface
• Number of Multicast and Broadcast packets:
– Multicasts = number of MAC multicast packets
– Broadcasts = number of MAC broadcast packets
• Number of runts, giants, and throttles packets:
– runts = number of packets that are less than 64B
– giants = packets that are greater than the MTU size
– throttles = packets containing PAUSE frames
• Number of CRC, overrun, and discarded packets:
– CRC = packets with CRC/FCS errors
– overrun = number of packets discarded due to FIFO
overrun conditions
– discarded = the sum of runts, giants, CRC, and
overrun packets discarded without any processing
Output Statistics: Displays output statistics sent out of the interface including:
• Number of packets, bytes, and underruns out of the
interface
• Packet size and the number of those packets outbound
to the interface
• Number of Multicast, Broadcast, and Unicast packets:
– Multicasts = number of MAC multicast packets
– Broadcasts = number of MAC broadcast packets
– Unicasts = number of MAC unicast packets
• Number of VLANs, throttles, discards, and collisions::
– Vlans = number of VLAN tagged packets
– throttles = packets containing PAUSE frames
– discarded = number of packets discarded without
any processing
– collisions = number of packet collisions
– wred=count both packets discarded in the MAC and
in the hardware-based queues
