password that enables the agent to receive packets from the
host and to send packets to the host. Minimum: eight
characters long.
priv des56 (OPTIONAL) Enter the keywords priv des56 to initiate a
privacy authentication level setting using the CBC-DES
privacy authentication algorithm (des56).
aes128 (OPTIONAL) Enter the keyword aes128 to initiate the
AES128-CFB encryption algorithm for transmission of SNMP
packets.
priv password (OPTIONAL) Enter a text string (up to 20 characters long)
password that enables the host to encrypt the contents of
the message it sends to the agent and decrypt the contents

History
Version 9.3(0.0) Added support for the AES128-CFB encryption algorithm on
the MXL 10/40GbE Switch IO Module platform.
Version 8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
No default values exist for authentication or privacy algorithms and no default
password exists. If you forget a password, you cannot recover it; the user must be
reconfigured. You can specify either a plain-text password or an encrypted cypher-
text password. In either case, the password is stored in the configuration in an
encrypted form and displayed as encrypted in the show running-config
command.
