CLI Guide

Line Description
• Number of packets and bytes into the interface
• Number of packets with IP headers and VLAN tagged
headers.
NOTE: The sum of the number of packets may not
be as expected since a VLAN tagged IP packet
counts as both a VLAN packet and an IP packet.
• Packet size and the number of those packets inbound to
the interface
• Number of symbol errors, runts, giants, and throttles
packets:
– symbol errors = number packets containing bad data.
That is, the port MAC detected a physical coding
error in the packet.
– 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, IP Checksum, overrun, and discarded
packets:
– CRC = packets with CRC/FCS errors
– IP Checksum = packets with IP Checksum errors
– overrun = number of packets discarded due to FIFO
overrun conditions
– discarded = the sum of runts, giants, CRC, IP
Checksum, 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
– packets = total number of packets
– bytes = total number of bytes
– underruns = number of packets with FIFO underrun
conditions
• 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 throttles and discards packets::
– throttles = packets containing PAUSE frames
– discarded = number of packets discarded without
any processing
Rate information... Estimate of the input and output traffic rate over a
designated interval (30 to 299 seconds). Traffic rate is
