Usage Guideline
To create a SMNP user, specify the security model that the user uses and the group that the user is created for.
To create an SNMPv3 user, the password used for authentication and encryption needs to be specified. An
SNMP user is unable to be deleted if it has been associated with a SNMP server host.
Example
This example shows how the plain-text password is configured for the user “user1” in the SNMPv3 group
public.
Switch# configure terminal
Switch(config)# snmp-server user user1 public v3 auth md5 authpassword priv
privpassword
Switch(config)#
This example shows how the MD5 digest string is used instead of the plain text password.
