snmp configuration password in c9300

[Leftz]

Hi snmp configuration is tried as below. I would like to know authentication password. Where is the password from? Is it from snmp server or somewhere else? Thanks

SW1(config)#snmp-server user SW-View viewNetwork v3 auth sha ?
WORD authentication password for user

the SNMP server and SW share same password, 
so the password you enter here must match the password you enter in SNMP server

you will use the user to poll SNMP to switch using SNMP or NMS Server

you can also use
