• DefaultSuper—Default SNMP view for administrator views.
Other views can be added.
• Object ID Subtree—Displays the subtree to be included or excluded in the SNMP view.
• Object ID Subtree View—Displays whether the defined subtree is included or excluded in the
selected SNMP view.
Creating SNMP Groups
In SNMPv1 and SNMPv2, a community string is sent along with the SNMP frames. The community string
acts as a password to gain access to an SNMP agent. However, neither the frames nor the community string
are encrypted. Therefore, SNMPv1 and SNMPv2 are not secure.
In SNMPv3, the following security mechanisms can be configured.
• Authentication—The device checks that the SNMP user is an authorized system administrator. This is
done for each frame.
• Privacy—SNMP frames can carry encrypted data.
Thus, in SNMPv3, there are three levels of security:
• No security (No authentication and no privacy)
