SNMP V3 Host error

[nmz]

I'm trying to setup SNMP V3 host and I got Timeout while connecting to <IP:161> error. I get result with snmpwalk command. I have no I idea what I have to fill in Macro. Those are my macro {$SNMPV3_AUTH} : AuthPriv, {$SNMPV3_NAME} : Testing, {$SNMPV3_PRIV} : %3aa~@tei~Hte
That is my snmpwalk sample command : snmpwalk -v3 -u Testing -l AuthPriv -a MD5 -A %3aa~@tei~Hte -x AES128 -X %3aa~@tei~Hte 10.0.64.102 system I need it urgent. I hope to get help.

Thanks

{$SNMPV3_AUTH} is -A value and {$SNMPV3_PRIV} is -X value.
