Service Manual

Line Description
• 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
Rate information... 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.
Time since... Elapsed time since the last interface status change (hh:mm:ss format).
