DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide 11. Cable Diagnostics Commands 11-1 test cable-diagnostics This command is used to start the cable diagnostics to test the status and length of copper cables. test cable-diagnostics interface INTERFACE-ID [, | -] Parameters interface INTERFACE-ID , - Specifies the interface ID. (Optional) Specifies a series of interfaces or separates a range of interfaces from a previous range. No space is allowed before or after the comma. (Optional) Specifies a range of interfaces. No space is allowed before or after the hyphen. Default None. Command Mode EXEC Mode. Usage Guideline This command is only available for physical port interface configuration. Cable Diagnostics can help users to detect whether the copper Ethernet port has connectivity problems. Use the test cable-diagnostics command to start the test. The copper port can be in one of the following status:  Open - The cable in the error pair does not have a connection at the specified position.  Short - The cable in the error pair has a short problem at the specified position.  Open or Short - The cable has an open or short problem, but the PHY has no capability to distinguish between them.  Crosstalk - The cable in the error pair has a crosstalk problem at the specified position.  Shutdown - The remote partner is powered off.  Unknown - The test got an unknown status.  OK - The pair or cable has no error.  No cable - The port does not have any cable connection to the remote partner. Example This example shows how to start the cable diagnostics to test the status and length of copper cables. Switch#test cable-diagnostics interface eth1/0/1 Switch# 11-2 show cable-diagnostics This command is used to display the test results for the cable diagnostics. show cable-diagnostics [interface INTERFACE-ID [, | -]] Parameters interface INTERFACE-ID (Optional) Specifies the interface ID. 91

Cable Diagnostics Commands
11-1
test cable-diagnostics
This command is used to start the cable diagnostics to test the status and length of copper cables.
test cable-diagnostics interface
INTERFACE-ID
[, | -]
Parameters
interface
INTERFACE-ID
Specifies the interface ID.
,
(Optional) Specifies a series of interfaces or separates a range of interfaces from
a previous range. No space is allowed before or after the comma.
-
(Optional) Specifies a range of interfaces. No space is allowed before or after the
hyphen.
Default
None.
Command Mode
EXEC Mode.
Usage Guideline
This command is only available for physical port interface configuration. Cable Diagnostics can help users to detect
whether the copper Ethernet port has connectivity problems. Use the test cable-diagnostics command to start the
test. The copper port can be in one of the following status:
Open
- The cable in the error pair does not have a connection at the specified position.
Short
- The cable in the error pair has a short problem at the specified position.
Open or Short
- The cable has an open or short problem, but the PHY has no capability to distinguish
between them.
Crosstalk
- The cable in the error pair has a crosstalk problem at the specified position.
Shutdown
- The remote partner is powered off.
Unknown
- The test got an unknown status.
OK
- The pair or cable has no error.
No cable
- The port does not have any cable connection to the remote partner.
Example
This example shows how to start the cable diagnostics to test the status and length of copper cables.
Switch#test cable-diagnostics interface eth1/0/1
Switch#
