Example: Configuring and Applying JUNOS Configuration Groups

In this example, the Simple Network Management Protocol (SNMP) configuration is divided between the group basic and the normal configuration hierarchy.

There are a number of advantages to placing the system-specific configuration (SNMP contact) into a configuration group and thus separating it from the normal configuration hierarchy—the user can replace (using the load replace command) either section without discarding data from the other.

In addition, setting a contact for a specific box is now possible because the group data would be hidden by the router-specific data.



[edit]
groups {
 basic {# User-defined group name
 snmp {# This group contains some SNMP data
 contact "My Engineering Group";


 community BasicAccess {
 authorization read-only;
}


}
apply-groups basic;# Enable inheritance from group "basic"
snmp {# Some normal (non-group) configuration
location "West of Nowhere";

This configuration is equivalent to the following:



[edit]
snmp {
location "West of Nowhere";
contact "My Engineering Group";


community BasicAccess {
authorization read-only;
}


}
