Define the Interface Range
The following example shows how to define 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 configured using the values saved in a named interface-range macro.
CONFIGURATION mode
interface range macro name
The following example shows how to change to the interface-range configuration 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, traffic 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.
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 reflectometer (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 reflection of the signal that returns. By examining
the reflection, TDR is able to indicate whether there is a cable fault (when the cable is broken, becomes unterminated, or if a
transceiver is unplugged).
TDR is useful for troubleshooting an interface that is not establishing a link; that is, when the link is flapping or not coming up.
TDR is not intended to be used on an interface that is passing traffic. When a TDR test is run on a physical cable, it is important
to shut down the port on the far end of the cable. Otherwise, it may lead to incorrect test results.
NOTE: TDR is an intrusive test. Do not run TDR on a link that is up and passing traffic.
To test and display TDR results, use the following commands.
