Line Description
Internet address... States whether an IP address is assigned to the interface. If
an IP address is assigned, that address is displayed.
MTU 1554... Displays link and IP MTU information. If the chassis is in
Jumbo mode, this number can range from 576 to 12000.
LineSpeed Displays the interface’s line speed.
ARP type:... Displays the ARP type and the ARP timeout value for the
interface.
Last clearing... Displays the time when the show interfaces counters
where cleared.
Queuing
strategy...
States the packet queuing strategy. FIFO means first in first
out.
Input Statistics: 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 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
170
