Service Manual

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 of the message it receives from the agent. Minimum: eight characters long.
access-list-name (Optional) Enter the standard IPv4 access list name (a string up to 16 characters long).
Defaults If no authentication or privacy option is configured, then the messages are exchanged (attempted anyway)
without any authentication or encryption.

Version Description
9.3(0.0) Added support for the AES128-CFB encryption algorithm on the MXL 10/40GbE Switch
IO Module platform.
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.
If you have an encrypted password, you can specify the encrypted string instead of the plain-text password. The
following command is an Example of how to specify the command with an encrypted string.
NOTE: The number of configurable users is limited to 16.
Example
Dell# snmp-server user privuser v3group v3 encrypted auth md5
9fc53d9d908118b2804fe80e3ba8763d priv des56 d0452401a8c3ce42804fe80e3ba8763d
Usage Information The following command is an example of how to enter a plain-text password as the string authpasswd for user
authuser of group v3group.
Example
Dell#conf
Dell(conf)# snmp-server user authuser v3group v3 auth md5 authpasswd
Usage Information The following command configures a remote user named n3user with a v3 security model and a security level of
authNOPriv.
Example
Dell#conf
Dell(conf)# snmp-server user n3user ngroup remote 172.31.1.3 udp-port 5009 3
auth md5 authpasswd

snmp-server user (for AES128-CFB Encryption)
Specify that AES128-CFB encryption algorithm needs to be used for transmission of SNMP information. The Advanced Encryption
Standard (AES) Cipher Feedback (CFB) 128-bit encryption algorithm is in compliance with RFC 3826. RFCs for SNMPv3 define two
authentication hash algorithms, namely, HMAC-MD5-96 and HMAC-SHA1-96. These are the full forms or editions of the truncated
versions, namely, HMAC-MD5 and HMAC-SHA1 authentication algorithms.
