Parameters
user-name: Username, a string of 1 to 32 characters.
group-name: Name of the group corresponding to the user, a string of 1 to 32 characters.
cipher: Specifies the authentication password (auth-password) or encryption password (priv-password)
to be in cipher text. The cipher text password can be calculated using the snmp-agent
calculate-password command.
authentication-mode: Specifies the security mode as authentication required. If you do not specify this
keyword, neither authentication nor encryption is performed.
md5: Uses HMAC MD5 algorithm for authentication.
sha: Uses HMAC SHA algorithm for authentication, which is securer than MD5.
auth-password: Authentication password, a string of 1 to 64 characters in plain text, a 32-bit
hexadecimal number in cipher text if MD5 algorithm is used, and a 40-bit hexadecimal number in cipher
text if SHA algorithm is used.
privacy: Specifies the security mode as encrypted.
des56: Specifies the encryption protocol as Data Encryption Standard (DES).
aes128: Specifies the encryption protocol as Advanced Encryption Standard (AES), which is securer
than DES.
priv-password: Encryption password, a string of 1 to 64 characters in plain text, a 32-bit hexadecimal
number in cipher text if MD5 algorithm is used, and a 40-bit hexadecimal number in cipher text if SHA
algorithm is used.
acl-number: Binds a user with an ACL, where acl-number represents ACL number, in the range 2000 to
2999. Using ACLs can restrict the source addresses of SNMP messages, namely, permitting or refusing
