Configuring the Network Cable Quality Check
Context
The network cable quality check allows you to locate network cable quality problems and take corresponding measures promptly, avoiding packet loss and its impact on services.
Only XGE electrical interfaces on the ES5D21X08T00 of S5730-HI, S5731-H, and S5731S-H, GE electrical interfaces on the S5731-H, S5735-L, S5735S-L, S5735S-L-M, S5735-S (except S5735-S48S4X), S5735S-S, S5735-S-I, S5720I-SI, and MultiGE electrical interfaces on the S5720-28X-PWH-LI-AC, S5720-28X-PWH-LI-ACF, S5732-H24UM2CC, S5732-H48UM2CC, S6720-32C-SI-AC, S6720-32C-SI-DC, S6720-32C-PWH-SI-AC, S6720-32C-PWH-SI, S6720-52X-PWH-SI, S6720-56C-PWH-SI-AC, and S6720-56C-PWH-SI support this function.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- Run cable-snr-test
The network cable quality check is configured.
- This command checks real-time quality of the network cable on an interface, and the network cable quality changes with the external environment.
- A MultiGE electrical interface supports accurate network cable quality check only when it works at the rate of 2.5 Gbit/s or higher.
- An XGE electrical interface supports accurate network cable quality check only when it works at the rate of 10 Gbit/s.
- A GE electrical interface supports accurate network cable quality check only when it works at the rate of 1 Gbit/s.
- An interface does not support the network cable quality check when it is Down or in loopback detection mode.
- After the interface goes Up, wait for several minutes before running this command. Otherwise, the command fails to be delivered.
