6.4.1.0 Changed the organization of the display output.
6.3.1.0 Added the Pluggable Media Type field in the E-Series output.
Usage
Information
Use the show interfaces command for details on a specific interface.
In the output of the show interfaces managementEthernet slot/port command, the value
displayed for the bytes field under the Input Statistics section is 4 bytes less for each packet that is
received (inbound) by the interface. For example, if 1000 packets, with each packet being 64 bytes in
size, arrive at the interface, the bytes count is displayed as 6000. The lower value for the byte statistical
counter is because of 4 bytes being discarded for each packet from the computation.
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 example.
Line Description
TenGigabitEther
net 1/1...
Interface type and administrative and line protocol status.
Hardware is... Interface hardware information, assigned MAC address, and current address.
Pluggable media
present...
Present pluggable media wavelength, type, and rate. The error scenarios are:
● Wavelength, unknown — Unable to determine the optics type
● Unknown — If the wavelength is reading an error
Dell EMC Networking allows unsupported SFP and XFP transceivers to be used,
but Dell EMC Networking OS might not be able to retrieve some data about them.
In that case, typically when the output of this field is “Pluggable media present,
Media type is unknown”, the Medium and the XFP/SFP receive power reading data
might not be present in the output.
Interface index... Displays the interface index number the SNMP uses 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 negotiation mode.
Energy Efficient
Ethernet
Displays whether Energy Efficient Ethernet has been enabled or not.
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.
