Chapter 13 Configuring Objects
Configuring Objects and Groups
Nesting Object Groups
You can nest object groups hierarchically so that one object group can contain other object groups of the
same type and you can mix and match nested group objects and regular objects within an object group.
The ASA does not support IPv6 nested object groups, however, so you cannot group an object with IPv6
entities under another IPv6 object-group.
To nest an object group within another object group of the same type, first create the group that you want
to nest (see the
“Configuring Object Groups” section on page 13-6 ), and then perform the steps in this
section.
Detailed Steps
Examples
Create network object groups for privileged users from various departments by entering the following
commands:
hostname (config)# object-group network eng
hostname (config-network)# network-object host 10.1.1.5
hostname (config-network)# network-object host 10.1.1.9
hostname (config-network)# network-object host 10.1.1.89
hostname (config)# object-group network hr
hostname (config-network)# network-object host 10.1.2.8
hostname (config-network)# network-object host 10.1.2.12
hostname (config)# object-group network finance
hostname (config-network)# network-object host 10.1.4.89
hostname (config-network)# network-object host 10.1.4.100
You then nest all three groups together as follows:
hostname (config)# object-group network admin
hostname (config-network)# group-object eng
hostname (config-network)# group-object hr
hostname (config-network)# group-object finance
Command Purpose
Step 1 object-group group {{protocol | network |
icmp-type } grp_id |service grp_id {tcp |
udp | tcp-udp}}
Example:
hostname(config)# object-group network
Engineering_group
Adds or edits the specified object group type under which you
want to nest another object group.
The service_grp_id is a text string up to 64 characters in length
and can be any combination of letters, digits, and the following
characters:
• underscore “_”
• dash “-”
• period “.”
Step 2 group-object group_id
Example:
hostname(config-network)# group-object
Engineering_groups
Adds the specified group under the object group you specified in
Step 1. The nested group must be of the same type. You can mix
and match nested group objects and regular objects within an
object group.
