hello sir,
is this Error in packet, Reason: authorizationError (access denied to that object) something to do with ssh access to the device?
do I need to make the username on snmpv3 match the username to access ssh to the device?
because, until now it still hasn't worked, is there really a problem with the device software?
thanks

it has nothing to do with ssh. You need only correct snmp v3 settings

Snmp user ena ssh user are 2 different user. You can have the same, but for security reason take 2 different.

The problem with the authorization is probably due to this part:
snmp-server view ViewDefault iso included

That give the user the base of the OID where it can parse the device.

Did you try to reproduce my config with your user settings ? (I mean username and encryption level)

Is there anything that needs to be fixed in the config?

Can you post this: show snmp view

And in your SNMP group config:
groupname: SnmpSwitch security model:v3 priv
contextname: <no context specified> storage-type: nonvolatile
readview : <no readview specified> writeview: <no writeview specified>
notifyview: *tv.FFFFFFFF.FFFFFFFF.FFFFFFFF.F
row status: active

The readview and writeview are not configured

Thats whas the reason I said you need this line:
snmp-server view ViewDefault iso included

So your group config should look like that:
snmp-server group SnmpSwitch v3 priv read ViewDefault write ViewDefault

okay, thanks for the suggestion, so I only need to add these 2 commands, okay?
snmp-server group SnmpSwitch v3 priv read ViewDefault write ViewDefault
snmp-server view ViewDefault iso included

or I can just add like this?
snmp-server group SnmpSwitch v3 priv read ViewDefault
snmp-server view ViewDefault iso included
