A composite operation is a set of operations that the Branch Gateway can perform when a rule matches a packet. Every rule in a policy list has an operation field that specifies a composite operation. The operation field determines how the Branch Gateway handles a packet when the rule matches the packet.

There are different composite operations for access control list rules and QoS list rules. For each type of list, the Branch Gateway includes a pre-configured list of composite operations. You cannot change or delete pre-configured composite operations. You can define additional composite operations.
