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]
To remove a user from the SNMP group, use the no 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] command.
Parameters
auth-password (OPTIONAL) Enter a text string (up to 20 characters long) password that enables the
agent to receive packets from the host and to send packets to the host. Minimum: eight
characters long.
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 to decrypt the
contents of the message it receives from the agent. Minimum: eight characters long.
Defaults If no authentication or privacy option is congured, then the messages are exchanged (attempted anyway) without
any authentication or encryption.
