Parameters user-name: Specifies the username, a case-sensitive string of 1 to 32 characters. group-name: Specifies the group name, a case-sensitive string of 1 to 32 characters. cipher: Sets ciphertext authentication and privacy keys, If this keyword is not specified, auth-password and priv-password must be plaintext keys. To obtain the hexadecimal ciphertext for a key, use the snmp-agent calculate-password command. authentication-mode: Specifies an authentication algorithm. MD5 is faster but less secure than SHA. For more information about these algorithms, see Security Configuration Guide. • md5: Specifies the MD5 authentication algorithm. • sha: Specifies the SHA-1 authentication protocol algorithm. auth-password: Specifies the authentication key string. This argument is case sensitive. If cipher is not specified, it must be a plaintext string of 1 to 64 characters. If cipher is specified, the ciphertext key length requirements differ by authentication algorithm and key string format, as shown in Table 21. Table 21 Encrypted authentication key length requirements Authentication algorithm MD5 SHA Hexadecimal string 32 characters 40 characters Non-hexadecimal string 53 characters 57 characters privacy-mode: Specifies an encryption algorithm for privacy. The three encryption algorithms AES, 3DES, and DES are in descending order of security. Higher security means more complex implementation mechanism and lower speed. DES is enough to meet general requirements. • 3des: Specifies the 3DES algorithm. • des56: Specifies the DES algorithm. • aes128: Specifies the AES algorithm. priv-password: Specifies the privacy key string. This argument is case sensitive. If cipher is not specified, it must be a plaintext string of 1 to 64 characters. If cipher is specified, the ciphertext key length requirements differ by authentication algorithm and key string format, as shown in Table 22.

The acl-number argument represents a basic ACL number in the range of 2000 to 2999. Only the NMSs with the IPv4 addresses permitted in the ACL can use the specified username to access the SNMP agent. 83
