Setup Guide

Dene the Interface Range
The following example shows how to dene an interface-range macro named “test” to select Ten Gigabit Ethernet interfaces 5/1 through
5/4.
Example of the define interface-range Command for Macros
Choosing an Interface-Range Macro
To use an interface-range macro, use the following command.
• Selects the interfaces range to be congured using the values saved in a named interface-range macro.
CONFIGURATION mode
interface range macro name
Example of Using a Macro to Change the Interface Range Conguration Mode
The following example shows how to change to the interface-range conguration mode using the interface-range macro named “test.”
DellEMC(config)# interface range macro test
DellEMC(config-if)#
Monitoring and Maintaining Interfaces
Monitor interface statistics with the monitor interface command. This command displays an ongoing list of the interface status (up/
down), number of packets, trac statistics, and so on.
To view the interface’s statistics, use the following command.
• View the interface’s statistics.
EXEC Privilege mode
Enter the type of interface and the interface information:
– For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport information.
– For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
Example of the monitor interface Command
The information displays in a continuous run, refreshing every 2 seconds by default. To manage the output, use the following keys.
• m — Change mode
• l — Page up
• T — Increase refresh interval (by 1 second)
• t — Decrease refresh interval (by 1 second)
• c — Clear screen
• a — Page down
• q — Quit
Maintenance Using TDR
The time domain reectometer (TDR) is supported on all Dell EMC Networking switches.
TDR is an assistance tool to resolve link issues that helps detect obvious open or short conditions within any of the four copper pairs. TDR
sends a signal onto the physical cable and examines the reection of the signal that returns. By examining the reection, TDR is able to
indicate whether there is a cable fault (when the cable is broken, becomes unterminated, or if a transceiver is unplugged).
