What to Do Next
See the “Monitoring SNMP” section on page 78-9.
Using SNMP Version 3
To configure parameters for SNMP Version 3, perform the following steps:
Step 1 Choose Configuration > Device Management > Management Access > SNMP.
Step 2 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.
Step 3 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
Step 4 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.
Step 5 Indicate the type of password you want to use by clicking one of the two radio buttons: Encrypted or
Clear Text.
Step 6 Indicate the type of authentication you want to use by clicking one of the two radio buttons: MD5 or
SHA.
Step 7 In the Authentication Password field, type the password to use for authentication.
