LAG/ECMP hashing on TTL/Hop Limit
Arista switches use the hashing algorithm to load balance traffic among LAG (Link Aggregation Group) members and among L3 ECMP (equal cost multipath) paths. In case of IP/IPV6 traffic, the hashing algorithm may include (if so configured for LAG) the typical IP packet fields such as source/destination IP address(es) as well as source/destination port(s) for UDP/TCP traffic. In order to improve traffic distribution for IPV4/IPV6 traffic, IPV4/TTL and IPV6/HopLimit fields have been added to the hashing algorithm for both LAG and ECMP starting EOS release 4.15.2F for the supported platforms listed below. Platform compatibility DCS-7300X series DCS-7050X series DCS-7250QX Configuration A new CLI for setting the TTL/Hop...
