Configuring SNMP Users
To configure a user for SNMP, perform this task:
Enforcing SNMP Message Encryption
You can configure SNMP to require authentication or encryption for incoming requests. By default the
SNMP agent accepts SNMPv3 messages without authentication and encryption. When you enforce
privacy, Cisco NX-OS responds with an authorization Error for any SNMPv3 PDU request using
securityLevel parameter of either noAuthNoPriv or authNoPriv.
Command Purpose
Step 1
switch# configuration terminal
Enters configuration mode.
Step 2
switch(config)# snmp-server user name
[auth {md5 | sha} passphrase [auto]
[priv [aes-128] passphrase] [engineID
id][localizedkey]]
Configures an SNMP user with authentication and
privacy parameters.
Step 3
switch(config-callhome)# show snmp user
(Optional) Displays information about one or more
SNMP users.
Step 4
