username: User name.
groupname: Specifies the group name for a user.
v1 | v2c | v3: Specifies the SNMP version. Only SNMPv3 supports later security parameters.
encrypted: The specified password input mode is ciphertext input. Otherwise, plaintext is used for input. If
ciphertext input is selected, enter a key consisting of continuous hexadecimal digits. An MD5 protocol
authentication key consists of 16 bytes and an SHA authentication protocol key consists of 20 bytes. Two
characters stand for one byte. Encrypted keys are valid for this engine only.
auth: Specifies whether authentication is used.
md5: Specifies the MD5 authentication protocol. sha specifies the SHA authentication protocol.
auth-password: Configures a password string (not more than 32 characters) used by the authentication
protocol. The system converts the passwords into the corresponding authentication keys.
priv: Specifies whether confidentiality is used. des56 specifies the use of the 56-bit DES encryption
protocol.
priv-password: Configures a password string (not more than 32 characters) used for encryption. The system
converts the password into the corresponding encryption key.
aclnum: ACL number. The specified ACL is associated and the range of IPv4 NMS addresses from which
access to the MIB is allowed is specified.
aclname: ACL name. The specified ACL is associated and the range of IPv4 NMS addresses from which
access to the MIB is allowed is specified.
ipv6-aclname: IPv6 ACL name. The specified ACL is associated and the range of IPv6 NMS addresses from
which access to the MIB is allowed is specified.
Configure user information so that the NMS can communicate with the agent by using a valid user.
For an SNMPv3 user, you can specify the security level, authentication algorithm (MD5 or SHA),
authentication password, encryption algorithm (at present, only DES is available), and encryption password.
times: Number of continuous failed attempts.
lock: After continuous authentication fails, the source IP address is permanently forbidden to initiate
authentication for access. The administrator needs to manually unlock the IP address.
