The use of SNMPv3 with password authentication and DES Encryption is mandatory to enable this 
service. (For more information on SNMPv3, see RFCs 2571-2575.) You are required to set a SNMPv3 
passphrase of at least 8 characters to enable SNMP system status monitoring. The first time you enter a 
SNMPv3 passphrase, you must re-enter it to confirm. The snmpconfig command “remembers” this 
phrase the next time you run the command.
