Cisco Cisco Email Security Appliance C160 Mode D'Emploi

Use the 

clustermode cluster

 command to change to the cluster mode. 

Remember: the 

clustermode

 command is the CLI command you use to 

change modes to the cluster, group, and machine levels. 

Type 

listenerconfig

 to see the listener settings configured for the cluster. 

Choose the machine you want to experiment with, then use the 

clusterset

 

command to copy settings from the cluster “down” to machine mode. 

Use the 

clustermode

 command to navigate to machine mode for the experimental 

machine, e.g.:

 

clustermode machine newyork.example.com

In machine mode, on the experimental machine, issue the 

listenerconfig

 

command to make changes specifically for the experimental machine. 

Commit the changes. 

Continue to experiment with the configuration changes on the experimental 
machine, remembering to commit the changes. 

When you are ready to apply your new settings to all the other machines, use the 

clusterset

 command to move the settings up to the cluster mode.

Commit the changes. 

You use the 

REMOVEMACHINE 

operation of 

clusterconfig 

to remove a machine 

permanently from a cluster. When a machine is permanently removed from a 
cluster, its configuration is “flattened” such that it will work the same as it did 
when it was part of the cluster. For example, if there is only a cluster-mode Global 
Unsubscribe table, the Global Unsubscribe table data will be copied to the 
machine’s local configuration when the machine is removed from the cluster.

A cluster does not allow the connected machines to have different versions of 
AsyncOS. Before you perform an upgrade of AsyncOS, you need to disconnect 
each machine in the cluster will via the 

clusterconfig

 command. After you 

upgrade all the machines, the cluster can be reconnected via the 

clusterconfig
