Concept Guide

Line Description
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 trac rate over a designated interval (30 to 299
seconds). Trac rate is displayed in bits, packets per second, and percent of line rate.
Time since... Elapsed time since the last interface status change (hh:mm:ss format).
Usage Information
The interface counter “over 1023-byte pkts” does not increment for packets in the range 9216 > x <1023.
The Management port is enabled by default (no shutdown). If necessary, use the ip address command to
assign an IP address to the Management port.
