Input Statistics: Description Displays the ARP type and the ARP timeout value for the interface. Displays the time when the show interfaces counters where cleared. States the packet queuing strategy. FIFO means first in first out. Displays all the input statistics including: • Number of packets and bytes into the interface • Number of packets with IP headers, VLAN tagged headers and MPLS 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 Note: Symbol errors is supported on E-Series EtherScale only. • 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 634 | Interfaces
