Table 25-45. Lines in show interfaces Command Example
Line Description
TenGigabitEthernet 2/0... Displays the interface’s type, slot/port, and administrative and line protocol status.
Hardware is... Displays the interface’s hardware information and its assigned MAC address.
Interface index... Displays the interface index number used by SNMP to identify the interface.
Internet address... States whether an IP address is assigned to the interface. If one is, 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 9252.
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, 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 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, 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
