Configuring object groups

About object groups

An object group is a group of objects that can be used by an ACL, object policy, or object group to identify packets. Object groups are divided into the following types:

·     IPv4 address object group—A group of IPv4 address objects used to match the IPv4 address in a packet or match the user from whom a packet comes.

·     IPv6 address object group—A group of IPv6 address objects used to match the IPv6 address in a packet or match the user from whom a packet comes.

·     Port object group—A group of port objects used to match the protocol port number in a packet.

·     Service object group—A group of service objects used to match the upper-layer service in a packet.

Restrictions and guidelines: Object group configuration

You cannot edit an object group if the group is used by a global static NAT rule.

Configuring an IPv4 address object group

1.     Enter system view.

system-view

2.     Create an IPv4 address object group and enter its view.

object-group ip address object-group-name

The system has one default IPv4 address object group named any.

3.     (Optional.) Configure a description for the IPv4 address object group.

description text

By default, an object group does not have a description.

4.     Configure an IPv4 address object.

[ object-id ] network { host { address ip-address | name host-name } | subnet ip-address { mask-length | mask | wildcard wildcard } | range ip-address1 ip-address2 | group-object object-group-name }

5.     Exclude an IPv4 address or a subnet from the IPv4 address object.

object-id network exclude { ip-address | subnet ip-address { mask-length | mask } }

By default, no IPv4 address in an IPv4 address object is excluded.

Support for this command depends on the device model. For more information, see the command reference.

6.     Exclude a host name from the IPv4 address object.

object-id network exclude host-name host-name

By default, no host name in an IPv4 address object is excluded.

Support for this command depends on the device model. For more information, see the command reference.

7.     (Optional.) Specify a security zone for the IPv4 address object group.

security-zone security-zone-name

By default, no security zone is specified for an IPv4 address object group.

Configuring an IPv6 address object group

1.     Enter system view.

system-view

2.     Create an IPv6 address object group and enter its view.

object-group ipv6 address object-group-name

The system has one default IPv6 address object group named any.

3.     (Optional.) Configure a description for the IPv6 address object group.

description text

By default, an object group does not have a description.

4.     Configure an IPv6 address object.

[ object-id ] network { host { address ipv6-address | name host-name } | subnet ipv6-address prefix-length | range ipv6-address1 ipv6-address2 | group-object object-group-name }

5.     Exclude an IPv6 address or a subnet from the IPv6 address object.

object-id network exclude { ip-address | subnet ipv6-address prefix-length }

By default, no IPv6 address in an IPv6 address object is excluded.

Support for this command depends on the device model. For more information, see the command reference.

6.     Exclude a host name from the IPv6 address object.

object-id network exclude host-name host-name

By default, no host name in an IPv6 address object is excluded.

Support for this command depends on the device model. For more information, see the command reference.

By default, an object group does not have a description.

4.     Configure a port object.

[ object-id ] port { { eq | lt | gt } port | range port1 port2 | group-object object-group-name }

Configuring a service object group

1.     Enter system view.

system-view

2.     Create a service object group and enter its view.

object-group service object-group-name

The system has multiple default service object groups.

3.     (Optional.) Configure a description for the service object group.

description text

By default, an object group does not have a description.

4.     Configure a service object.

[ object-id ] service { protocol [ { source { { eq | lt | gt } port | range port1 port2 } | destination { { eq | lt | gt } port | range port1 port2 } } * | icmp-type icmp-code | icmpv6-type icmpv6-code ] | group-object object-group-name }

Renaming an object group

1.     Enter system view.

system-view

2.     Rename an object group.

object-group rename old-object-group-name new-object-group-name

You can only rename non-default object groups.

Configuring aging of DNS-resolved IP addresses from host names

About this task

In load balancing scenarios where one host name maps to several IP addresses, DNS-resolved IP address for a host name changes between these mapping addresses. Upon every change, the object group module notifies relevant policies of the change, which causes policies to submit changes frequently and consumes memory. To resolve this issue, you can enable aging of DNS-resolved IP addresses from host names.

With this feature enabled, the system maintains an IP address group for each host name. If a resolved IP address is not in the group, the system adds the address to the group and notifies relevant policies of the change. If a resolved IP address is in the group, the system does not notify relevant policies and update the aging time for the resolved IP address. If an IP address in the group reaches its aging time, the system deletes it from the group and notifies relevant policies. This reduces rule matching accelerations for the relevant policies and lowers the memory usage.
