Embodiments include receiving configuration information including a match criterion for packets received at a network device in a network and a pool of layer 3 addresses associated with a set of servers in the network, resolving layer 2 destination addresses based on the layer 3 addresses of the servers, and programming a hardware layer of the network device based, at least in part, on the match criterion, the pool of layer 3 addresses, and the layer 2 destination addresses. Specific embodiments include configuring a policy to indicate that packets from an external source are to be forwarded to a server of the set of servers. Further embodiments include receiving a packet at the network device, and matching the packet to the pool of layer 3 addresses and the resolved layer 2 addresses based, at least in part, on the match criterion programmed in the hardware layer.

Scalable network address translation at high speed in a network environment

In one embodiment a packet of data is received at a network element. At least one field is parsed from the packet of data. A forwarding entry is identified from a plurality of forwarding entries based on the at least one field. The forwarding entry of the plurality of forwarding entries is formed by merging information from at least one load balancing entry and at least one access control list (ACL) entry. The data packet is forwarded through a port of the network element in accordance with the identified forwarding entry.
