mode, authPriv as the security level, SHA as the authentication algorithm, 1234 as the 
authentication password, DES as the privacy algorithm and 1234 as the privacy password:
Switch#configure
Switch(config)#snmp-server user admin remote nms1 smode v3 slev authPriv cmode 
SHA cpwd 1234 emode DES epwd 1234
Switch(config)#show snmp-server user
