Service Manual
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.
Line Description
TenGigabitEthernet
1/1...
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-qualied — 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-qualied — if wavelength is reading error, and F10 ID is not
present
Dell Networking allows unsupported SFP and XFP transceivers to be used, but Dell
Networking OS might not be able to retrieve some data about them. In that case,
typically when the output of this eld 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.
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 rst in rst 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
– giants = packets that are greater than the MTU size
– throttles = packets containing PAUSE frames
630
