F5 BIG-IP Link Controller cannot be auto-discovered virtual servers

 F5 BIG-IP Link Controller cannot be auto-discovered virtual servers,

LC Bigip Version: BIG-IP 15.1.1 Build 0.0.6 

Problem：

A new VS is added to the LTM module of the F5 LC, but the newly added VS cannot be automatically found in the link control module of the same F5 LC.

This cw VS was added three days ago，

This test2 was added half an hour ago

note:

I found that ,the standby LC must be restarted before the vs can be discovered by active LC.😂
