Using SNMP Version 3
To configure parameters for SNMP Version 3, perform the following steps:
Step1 Choose Configuration > Device Management > Management Access > SNMP.
Step2 In the SNMPv3 Users pane, to add a configured user or a new user to a group, click Add. To change user
parameters, click Edit. To remove a configured user from a group, click Delete. When you remove the
last user in a group, ASDM deletes the group.
Note After a user has been created, you cannot change the group to which the user belongs.
The Add SNMP User Entry dialog box appears.
Step3 From the Group Name drop-down list, choose the group to which the SNMP user belongs. The available
groups are as follows:
•Auth&Encryption, in which users have authentication and encryption configured
•Authentication_Only, in which users have only authentication configured
•No_Authentication, in which users have neither authentication nor encryption configured
Step4 In the Username field, enter the name of a configured user or a new user. The username must be unique
for the SNMP server group selected.
Step5 Indicate the type of password you want to use by clicking one of the two radio buttons: Encrypted or
Clear Text.
Step6 Indicate the type of authentication you want to use by clicking one of the two radio buttons: MD5 or
SHA.
Step7 In the Authentication Password field, type the password to use for authentication.
