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 interfaces 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
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
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).
Usage
Information
The interface counter over 1023-byte pkts does not increment for packets in the range 9216 > x <1023.
The Management port is enabled by default (no shutdown). If necessary, use the ip address
command to assign an IP address to the Management port.
