Engine Editor > General > Clustering

Use this branch to view nodes and add new nodes to the Security Engine cluster.

Option	Definition
Node ID (Not editable)	Shows the ID number of the node.
Name	Specifies the name of the node. Double-click the cell to edit the name.
Configuration Status (Not editable)	Shows the configuration status of the node.
Certificate (Optional)	Shows information about the node's certificate for external certificate management. Right-click the cell, then select Edit Certificate to create a certificate request for the Security Engine node. You must create a separate certificate request for each Security Engine node.
Version (Not editable)	Shows the version of the Security Engine software that is installed on the engine.
Comment (Optional)	A comment for your own reference.
SNMP Location	Specifies the SNMP location string that is returned on queries to the SNMPv2-MIB or SNMPv2-MIB-sysLocation object.
SNMP Engine ID (SNMPv3 only)	A unique identifier for each Security Engine node that is used by the SNMP agent. The engine ID is used with a hash function to generate keys for authentication and encryption of SNMPv3 messages. If you do not specify the SNMP engine ID, an SNMP engine ID is automatically generated.
Disabled	Disables the node. You can enable the node later.
Add Node	Adds a node to the cluster. Opens the Engine Node Properties dialog box.
Edit Node	Allows you to change the properties of the selected node. Opens the Engine Node Properties dialog box.
Remove Node	Deletes the selected node. The deleted node cannot be restored.
Clustering Mode (Not Layer 2 Engines)	Balancing — All nodes are simultaneously online providing enhanced performance and high availability if there is node failure. Balancing mode is the default mode. Standby — Only one node can be online at a time. We recommend having at least one other node on standby to allow automatic takeover if there is failure. Several nodes can be on standby at a time. A randomly selected standby node is turned online when the online node fails. Note: Only standby clustering mode is supported for Layer 2 Engine Clusters.
Clustering	Allows you to change advanced settings for the cluster. Opens the Advanced Cluster Settings dialog box.
