5. Select Monitoring > Ports > Cable Test.
The Cable Test page displays.
6. If a stack is configured, select whether to display the physical interfaces for one switch
or for all switches in the stack:
• Unit ID for a stacked switch: The physical interfaces for the switch with the
selected stack unit ID are displayed.
If no switch stack is configured, the only option is unit ID 1.
• All: The physical interfaces for all switches in the stack are displayed.
If no switch stack is configured, the All option does not have any effect.
7. Select the check boxes that are associated with the physical ports for which you want
to test the cables.
8. Click the Apply button.
A cable test is performed on the selected interface. The cable test might take up to
two seconds to complete. If the port has an active link, the cable status is always
Normal. The command returns a cable length estimate if this feature is supported
by the PHY for the current link speed. Note that if the link is down and a cable is
attached to a 10/100 Ethernet adapter then the cable status might be Open or Short
because some Ethernet adapters leave unused wire pairs unterminated or grounded.
The following table describes the view-only fields on the page.
Table 184. Cable Test
