Defaults If no authentication or privacy option is congured, then the messages are exchanged (attempted anyway) without
any authentication or encryption.

Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
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 recongured. You can specify either a plain-text password or an
encrypted cypher-text password. In either case, the password is stored in the conguration 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 congurable 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 congures 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
Related Commands show snmp user — displays the information congured on each SNMP user name.
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 dene 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.
Syntax
snmp-server user name {group_name remote ip-address udp-port port-number} [1 |
2c | 3] [encrypted] [auth {md5 | sha} auth-password] [priv {des56 | aes128–cfb}
priv– password] [access access-list-name | ipv6 access-list-name | access-list-
name ipv6 access-list-name]
