The no form of the command disables access via SNMP v3 for the specified user.
Syntax Description	v3	Configures SNMPv3 users.
	auth	Configures SNMPv3 security parameters, specifying passwords in plaintext on the command line (note: passwords are always stored encrypted). Available hash-type options are: <md5\|sha\|sha224\|sha256\|sha384\|sha512>.

Default	No SNMP v3 users defined
Configuration Mode	config
History	3.1.0000 3.7.0000 3.8.1000: Syntax updated
Example	switch (config) # snmp-server user admin v3 enable
Related Commands	show snmp user
Notes	The username chosen here may be anything that is valid as a local UNIX username (alphanumeric, plus '-', '_', and '.'), but these usernames are unrelated to, and independent of, local user accounts. That is, they need not have the same capability level as a local user account of the same name. Note that these usernames should not be longer than 31 characters, or they will not work. The hash algorithm specified is used both to create digests of the authentication and privacy passwords for storage in configuration, and also in HMAC form for the authentication protocol itself There are three variants of the command, which branch out after the “v3” keyword. If “auth” is used next, the passwords are specified in plaintext on the command line. If “encrypted” is used next, the passwords are specified encrypted (hashed) on the command line. If “prompt-pass” is used, the passwords are not specified on the command line the user is prompted for them when the command is executing. If “priv” is not specified, only the auth password is prompted for. If “priv” is specified, the privacy password is prompted for; entering an empty string for this prompt will result in using the same password specified for authentication. AES privacy type encryption using the newest algorithm, which means we use aes-blumenthal. For more information see http://www.snmp.com/eso/esoConsortiumMIB.txt. No more than 30 SNMPv3 users are allowed in the database
