Service Manual

Version Description
7.5.1.0 Introduced on the C-Series.
6.4.1.0 Changed the organization of the display output.
6.3.1.0 Added the Pluggable Media Type eld in the E-Series output.
Usage Information
Use the show interfaces command for details on a specic interface.
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
TenGigabitEthernet
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, Non-qualied — Dell ID is not present, but wavelength information is
available from XFP or SFP serial data
• Wavelength, F10 unknown — Dell ID is present, but not able to determine the optics
type
• Unknown, Non-qualied — 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
