The table of users configured in the SNMP engine's Local Configuration Datastore (LCD). To create a new user (i.e., to instantiate a new conceptual row in this table), it is recommended to follow this procedure: 1) GET(usmUserSpinLock.0) and save in sValue. 2) SET(usmUserSpinLock.0=sValue, usmUserCloneFrom=templateUser, usmUserStatus=createAndWait) You should use a template user to clone from which has the proper auth/priv protocol defined. If the new user is to use privacy: 3) generate the keyChange value based on the secret privKey of the clone-from user and the secret key to be used for the new user. Let us call this pkcValue. 4) GET(usmUserSpinLock.0) and save in sValue. 5) SET(usmUserSpinLock.0=sValue, usmUserPrivKeyChange=pkcValue usmUserPublic=randomValue1) 6) GET(usmUserPulic) and check it has randomValue1. If not, repeat steps 4-6. If the new user will never use privacy: 7) SET(usmUserPrivProtocol=usmNoPrivProtocol) If the new user is to use authentication: 8) generate the keyChange value based on the secret authKey of the clone-from user and the secret key to be used for the new user. Let us call this akcValue. 9) GET(usmUserSpinLock.0) and save in sValue. 10) SET(usmUserSpinLock.0=sValue, usmUserAuthKeyChange=akcValue usmUserPublic=randomValue2) 11) GET(usmUserPulic) and check it has randomValue2. If not, repeat steps 9-11. If the new user will never use authentication: 12) SET(usmUserAuthProtocol=usmNoAuthProtocol) Finally, activate the new user: 13) SET(usmUserStatus=active) The new user should now be available and ready to be used for SNMPv3 communication. Note however that access to MIB data must be provided via configuration of the SNMP-VIEW-BASED-ACM-MIB. The use of usmUserSpinlock is to avoid conflicts with another SNMP command generator application which may also be acting on the usmUserTable.
