6.3.1.0 Added the Pluggable Media Type field in the E-Series TeraScale output.
Usage Information
Use the show interfaces command for details on a specific interface. Use the show interfaces
linecard command for details on all interfaces on the designated line card.
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.
The following table describes the show interfaces command shown in the 10G example.
Line Description
TenGigabitEthern
et 0/0...
Interface type, slot/port, 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, Non-qualified — Dell Force10 ID is not present, but wavelength
information is available from XFP or SFP serial data
• Wavelength, F10 unknown—Dell Force10 ID is present, but not able to determine the
optics type
• Unknown, Non-qualified— if wavelength is reading error, and F10 ID is not present
Dell Networking allows unsupported SFP and XFP transceivers to be used, but the
system 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 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
