A method for configuring network devices. The method includes selecting a first hash function to use to process packets using Equal-Cost Multi-Path (ECMP) on a network device, where the first hash function is selected from a set of hash functions using a second hash function, a network chip ID of the network chip in the network device, a network device media access control (MAC) address, and an ECMP flag. The method further includes selecting a third hash function to use to process packets using a Link Aggregation Group (LAG), where the third hash function is selected from the set of hash functions using a fourth hash function, the network chip ID of the network chip in the network device, the network device MAC address, and the LAG flag. The method further includes processing a packet received by the network device using the first hash function or the third hash function.
