Parameters
plain-password
: Specifies a plaintext authentication or privacy key.
mode
: Specifies authentication and privacy algorithms. Select a mode option, depending on the
authentication and privacy algorithm you are configuring with the
snmp-agent usm-user v3
command.
The three privacy algorithms Advanced Encryption Standard (AES), Triple Data Encryption Standard
(3DES), and Data Encryption Standard (DES) are in descending order of security strength. Higher
security means more complex implementation mechanism and lower speed. DES is enough to meet
general requirements. The Message-Digest Algorithm 5 (MD5) and Secure Hash Algorithm (SHA-1) are
the two authentication algorithms. MD5 is faster but less secure than SHA-1.
•
3desmd5
: Converts the plaintext privacy key to an encrypted key for 3DES encryption used together
with MD5 authentication.
•
3dessha
: Converts the plaintext privacy key to an encrypted key for 3DES encryption used together
with SHA-1 authentication.
•
md5
: Converts the plaintext authentication key to an encrypted key for MD5 authentication, or
converts the plaintext privacy key to an encrypted key for AES or DES encryption used in
conjunction with MD5.
•
sha
: Converts the plaintext authentication key to an encrypted key for SHA-1 authentication, or
converts the plaintext privacy key to an encrypted key for AES or DES encryption used in
conjunction with SHA-1 authentication.
local-engineid
: Uses the local engine ID to calculate the encrypted key. For more information about
engine ID-related configuration, see the
snmp-agent local-engineid
command.
specified-engineid
: Uses a user-defined engine ID to calculate the cipher text password.
engineid
: Specifies an SNMP engine ID as a hexadecimal string. It must comprise an even number of
hexadecimal characters, in the range of 10 to 64. All-zero and all-F strings are invalid.
Description
Use
snmp-agent calculate-password
to convert a plaintext key to an encrypted key for authentication or
encryption.
This command helps you calculate encrypted authentication and privacy keys for SNMPv3 users that use
encrypted authentication and privacy keys. To create an SNMPv3 user, see the
snmp-agent usm-user v3
command.
Make sure the SNMP agent is enabled before you execute the
snmp-agent calculate-password
command.
The converted key is valid only under the engine ID specified for key conversion.
