cluster commands in LSA architecture

Dear community members,


I have a question regarding LSA implementation, any input is appreciated.

 

in "NSO Layered Service Architecture" manual, there is no mention of cluster commands, but in -for example- "example-22 init.sh" there are these cluster commands :

 

set cluster device-notifications enabled
set cluster remote-node lower-nso-1 address 127.0.0.1 port 2023 authgroup default username admin
set cluster remote-node lower-nso-2 address 127.0.0.1 port 2024 authgroup default username admin
set cluster commit-queue enabled

 

What is the use of and/or benefit of enabling cluster device-notifications in an LSA setup compared to enabling device-notifications via ncs.conf ?

What is the use of enabling cluster commit-queue in an LSA setup compared to "devices global-settings commit-queue" settings?
What is the use of defining lower-nso nodes as cluster remote-node in upper-nso in an LSA setup ?


Thanks and regards
