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 will belong. 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.
Step 8 Indicate the type of encryption you want to use by clicking one of these three radio buttons: DES, 3DES,
or AES.
Step 9 If you chose AES encryption, then from the AES Size drop-down list, choose the level of AES
encryption to use: 128, 192, or 256.
Step 10 In the Encryption Password field, type the password to use for encryption. The maximum number of
characters allowed for this password is 64.
Step 11 Click OK to create a group (if this is the first user in that group), display this group in the Group Name
drop-down list, and create a user for that group.
The Add SNMP User Entry dialog box closes.
The SNMPv3 Users pane lists the following information: SNMP Version 3 server group name, name of
the user that belongs to the specified group, encrypted password setting, authentication setting,
encryption algorithm setting, and the AES size setting.
Step 12 Click Apply.
SNMP parameters for Version 3 are configured, and the changes are saved to the running configuration.

Monitoring SNMP
NMSs are the PCs or workstations that you set up to monitor SNMP events and manage devices, such as
the adaptive security appliance.You can monitor the health of a device from an NMS by polling required
information from the SNMP agent that has been set up on the device. Predefined events from the SNMP
agent to the NMS generate syslog messages. This section includes the following topics:
