User Guidelines
If the SNMP local engine ID is changed, configured users will no longer be
able to connect and will need to be re-configured (deleted from the
configuration and added back).
Use of MD5 authentication in conjunction with AES privacy is discouraged
as it results in a weak cypher. Utilize SHA authentication when using AES
privacy.
The SNMP group must exist or an error is displayed and the user is not
configured. The user name can consist of any printable character and may
contain embedded blanks if enclosed in quotes.
Example
The following example configures an SNMPv3 user “John” in group “user-
group”.
console(config)# snmp-server user John user-group
