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.
On the S4810, the show interface output displays incorrect rate information details over
time for link monitoring when the rate-interval is configured for 5 seconds. Dell Force10
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
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 Force10 allows unsupported SFP and XFP transceivers to be
used, but FTOS 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.
