Cable Test
Use the Cable Test screen to display information about the cables connected to switch ports.
To display the cable test screen:
1. Select Monitoring
Ports > Cable Test.
2. Select whether to display physical interfaces, link aggregation groups (LAGs), or both by
clicking one of the following links above the table heading:
• 1. On
ly physical interfaces are displayed. This is the default setting.
• All.
Both physical interfaces and link aggregation groups are displayed.
To locate an interface quickly, type the interface number (for example, xg12) in the Go To
I
nterface field at the top or bottom of the table and click Go.
3. Click App
ly to perform a cable test on the selected interface.
The cable test can take up to 2 seconds to complete. If the port has an active link then the
link is not t
aken down and 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 can be Open or Short because some Ethernet adapters leave unused wire
pairs unterminated or grounded.
