Cisco SD-WAN OMP

[RS19]

I am using default feature template for the OMP

In the default OMP template, there is option for graceful restart timer value. I want to change the timer value

but when i tried to edit & change the default OMP value it is not allowing me to do ? The option is greyed out to change the value.

Wanted to check how to change the OMP graceful timer value from the vManage GUI .

Have you changed it from default to global?

It is not allowing me to Edit & change it to Global.

Is it because this is the default template & this template is already assigned to other devices templates ?
