To view existing SNMP users, click SNMP under Configuration > System Configuration in the
tree view and click Manage SNMP Users. Alternatively, you can click the Manage SNMP User
Access link located on the Configuration > Security and Access > Users page.
The admin user or a user with privileges for the SNMP feature can modify the security level,
authentication pass phrase, and privacy pass phrase for existing SNMP users, and create or
delete SNMP users. Pass phrases differ from passwords only in length—pass phrases are
usually much longer than passwords. Their greater length makes pass phrases more secure.
The IPSO implementation of SNMP supports DES and MD5 authentication to automatically
generate USM keys.
SNMP must be enabled on the system before you can set an SNMP user authentication or
privacy pass phrase.
Note
If you change the security level from either authPriv or authPrivReq to authNoPriv, the
privacy pass phrase is automatically deleted. If you change it back to authNoPriv, you must
supply a privacy pass phrase.
