3.2.3 Configuring a Working Mode for an APS Group

A working mode can be configured for an APS group. The NE80E/40E supports APS working
modes, including automatic APS switching, and delayed switchback with the wait to restore
(WTR) time configured. An APS working mode must be configured on a protection interface.
Context
Automatic APS switching modes are classified into 1:1 bidirectional and 1+1 unidirectional.
The default automatic APS switching mode is 1+1 unidirectional.
After a fault in the working link is rectified, services automatically switch from the protect link
to the working link. During the switchback, some service traffic is dropped because some
resources related to the working link or NE80E/40E are being restored. To prevent service loss,
the WTR time can be set on the NE80E/40E to delay a switchback. Services can automatically
switch from the protect link back to the working link in the specified WTR time after the working
link becomes available.
Perform the following steps on a protection interface in an APS group:
