LAG Hashing on Stacking Products

LAG hashing on stacking products is required when multicast routing is configured on a tunnel interface and the IP multicast packets terminate in the tunnel (for example, when the ip pim, ip pim-sparse, or ip igmp proxy multicast routing commands are configured on a tunnel interface).

Stacking trunk hashing for FastIron devices is dynamic. Based on load, traffic is distributed across individual links in the trunk. Stacking trunks on ICX 7150 devices are an exception. Just as on ICX 7150 Layer 2 LAGs, ICX 7150 stacking trunks hash traffic based on traffic type, for example, Layer 2, Layer 3, and Layer 4 header information.
