Line Description
• 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 the 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
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).
