Configuring LAG Hash

LAG-Hash is used to describe the load-balancing algorithm used for distributing traffic across the links within a port channel. This algorithm plays a crucial role in determining the distribution of traffic evenly among the member links of the port channel.

OPBNOS uses the CRC2 for NVIDIA ASIC and CRC32_LO for Broadcom ASIC for load-balancing traffic across a port channel.
