If SNMPv3 is used, you can configure the SNMPv3 Engine ID and SNMP priority. Configuring the SNMPv3 Engine ID provides maximum security for SNMP management.
To configure SNMPv3 engine IDs
Select Mandatory Require SNMPv3. This disables SNMPv1/v2 and allows only SNMPv3 access, which provides maximum security for SNMP management.
If you select this option, you must specify an asset number on the General page before clicking OK.
Enter the hexadecimal Engine ID number in the Engine ID field.
SonicOS automatically populates this field, but you can change it. This number is matched against received SNMP packets to authorize their processing; only packets whose Engine ID matches this number are processed.
Optionally, enable Increase SNMP subsystem priority.
For efficient system operation, certain operations might take priority over responses to SNMP queries. Enabling this option causes the SNMP subsystem to always respond and operate at a higher system priority.
Enabling this option might affect the performance of the overall system.
Click OK. The SNMPv3 security options are now used in processing packets.
