Setting The Delay Time For The System To Consider A Clock Source Lost; Setting The Wtr Time Of A Clock Source - Huawei Quidway S9300 Configuration Manual

Quidway S9300 Terabit Routing Switch
Configuration Guide - Device Management
Do as follows on the S9300.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
clock freq-check
Frequency offset check is enabled to affect clock source selection.
By default, the result of frequency offset check does not affect clock source selection.
Step 3 Run:
clock freq-check-range left-range right-range
The valid range of the frequency offset is set. If the frequency offset of a clock source is out of
the specified range, the clock source fails to pass the frequency offset check.
By default, the valid range of the frequency offset is -9.2 ppm to 9.2 ppm.

Do as follows on the S9300.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
clock hold-off-time hold-off-time source source
