Description
Displays all the input statistics including:
• 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 input symbol errors, runts, giants, CRC, IP
Checksum, and overrun packets discarded without any processing
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
Estimate of the input and output traffic rate over a designated interval (30 to
299 seconds).
Traffic rate is displayed in bits, packets per second, and percent of line rate.
Elapsed time since the last interface status change (hh:mm:ss format).
