This read-create INTEGER specifies the SNMPv3 security level, noAuthNoPriv, authNoPriv, authPriv, or none, applied to traps sent to the server identified by this row of zxr10SnmpTrapSvrTable. An admin sets it in conjunction with zxr10TrapSvrVersion being v3 to control whether outgoing traps to this server are authenticated, encrypted, both, or neither. For example, an admin sets zxr10TrapSvrSecurityLevel to authPriv for a trap server on an untrusted network segment so notifications are both authenticated and encrypted in transit.
