Command Line Reference Guide

NOTE: In the CLI output, the power value will be rounded to a 3-digit value.
For receive/transmit power that is less than 0.000, an snmp query will return
the corresponding dbm value even though the CLI displays as 0.000.
NOTE: After the counters are cleared, the line-rate continues to increase until
it reaches the maximum line rate. When the maximum line rate is reached,
there will be no change in the line-rate.
User
Information
The following describes the show interfaces command shown in the 10G
example below.
Line Description
TenGigabitEthern
et 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
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
