Abstract: One aspect of the instant application provides a system and method for generating internal traffic for a switch. During operation, the system configures a replication list comprising a plurality of replication entries, with a respective replication entry corresponding to a destination port on the switch. The system generates a seed packet to be replicated for each replication entry in the replication list, with a destination address of a respective replicated packet corresponding to a replication entry. All replicated packets are associated with a virtual local-area network (VLAN) reserved for the internal traffic. The system then forwards the replicated packets along with external packets received by the switch to corresponding destination ports on the switch.

Abstract: One embodiment provides a system and method for facilitating a dynamic policy engine with recursive key selection. During operation, the system can receive, at a network device, a user request to create a policy table, the user request including multiple groups of policy fields and specifying an amount of hardware resource for the policy table. The system can in response to determining that an amount of unallocated hardware resource is less than the amount of hardware resource specified in the user request, free a portion of allocated hardware resources and allocate the specified amount of hardware resource for the policy table. The system can identify, based on the user request, an optimized matching policy template that accommodates the multiple groups of policy fields. The system can then configure, based on the optimized matching policy template, one or more hardware template registers; and create the policy table.
