Configuring object groups

Overview

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.
