Hello, friend!
I suggest you can do this:
1. Choose Inventory > SDH Report > Statistics Report of SDH Protection Subnet Resources from the main menu (traditional style); alternatively, double-click Fix-Network NE Configuration in Application Center and choose Inventory > SDH Report > Statistics Report of SDH Protection Subnet Resources from the main menu (application style).
2. In the Filter window, select the protection subnet type and click Filter.
3. In the Statistics Report of the SDH Protection Subnet Resource window, view the resources of the qualified protection subnets.
4. Optional: Click Print or Save As to output the report.
This operation is very simple, you can try it.
Thanks!
