9800 ups optical-layer ASON taking too long to switch

Dear friend!
Please check whether the switching delay is configured. If yes, delete the switching delay or reduce the switching delay.
To prevent the failure of WDM equipment to complete protection switching in a timely manner, you are advised to comply with the following two points:
1. If no protection nesting exists, do not set the WDM switching delay time. (That is, the value of this parameter is 0, and the default value is 0.)
2. When switching is nested, the delay of each nested level of outer protection is increased by 50 ms.

In addition, check whether the ASON rerouting time increases because OCh routes on the WDM network are too complex. If yes, please optimize the WDM network.

Thank you！

Thank you so much for your help as always. I will test the switch during the maintenance window and report the results.

Friends.
What really solved it was a change in the preset route.
