Cisco Cisco Email Security Appliance C190 Guida Utente

If there are two or more, as in our example, decide if those two will share any 
settings with each other that are not shared with the cluster. In that case, you will 
be creating one or more groups for them. Otherwise, you will make machine level 
settings for each, and do not need to have extra groups.

In our case we want to run 

clusterconfig

 from the CLI on any of the machines 

already in the cluster, and select ADDGROUP. We will do this twice, once for 
Paris and once for Rome.

Now you can begin using the GUI and CLI to build configuration settings for the 
cluster and for ALL the groups, even if the groups have no machines in them yet. 
You will only be able to create machine specific settings for machines after they 
have joined the cluster.

The best way to create your override or exceptional settings is to copy the settings 
from the higher (e.g. cluster) level down to a lower (e.g. group) level.

For example, after creating the cluster our 

dnsconfig

 settings initially looked like 

this:

Configured at mode:

Cluster: Yes

Group Main_Group: No

Group Paris: No

Group Rome: No

Machine lab2.cable.nu: No

If we "Copy to Group" the DNS settings, it will look like this:

Configured at mode:

Cluster: Yes

Group Main_Group: No

Group Paris: Yes

Group Rome: No

Machine lab2.cable.nu: No
