Command History
Version Description
9.9(0.0) Introduced on the FN IOM and added support to display the interface configurations
corresponding to a range of ports.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information Starting with Dell Networking OS Release 9.3(0.0), you can also view the configuration of 40-Gigabit Ethernet
interfaces by using the fortyGigE keyword with the show interface interface-type brief
command. For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE followed by the slot/port
information to indicate the interface.
Use the show interfaces command for details on a specific interface. Use the show interfaces
stack-unit command for details on all interfaces on the designated stack unit.
On the switch, the show interface output displays incorrect rate information details over time for link
monitoring when the rate-interval is configured for 5 seconds. Dell Networking OS recommends using higher rate-
intervals, such as 15 to 299 seconds, to minimize the errors seen.
NOTE: In the CLI output, the power value is rounded to a 3-digit value. For receive/transmit power
that is less than 0.000, an snmp query returns 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 is no change in the line-rate.
User Information
The following table describes the show interfaces command shown in the 10G (TeraScale) Example below.
Line Description
TenGigabitEthernet
2/0...
Interface type, slot/port, and administrative and line protocol status.
Hardware is... Interface hardware information, assigned MAC address, and current 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.
LineSpeed Displays the interface’s line speed, duplex mode, and Slave.
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 VLAN tagged headers
• Packet size and the number of those packets inbound to the interface
• Number of Multicast and Broadcast packets:
• Multicasts = number of MAC multicast packets
• Broadcasts = number of MAC broadcast packets
• Number of runts, giants, and throttles packets:
• runts = number of packets that are less than 64B
