Hello everyone,
I am currently working on C9200 IOS-XE switches. I have to set up the SNMP service for supervision. I configured the service but there is no connection with the server that should receive the notifications. At first I thought the problem was related to the server but when I use the snmpwalk utility from the administration machine, I have the code Unknown user name.
Below is the configuration and results of the Show commands:

Can you please tell me if there is a particular parameter to activate on the 9000 series for it to work?
Thanks in advance !
