Do i need to configure STP to prevent mesh packet traffic or loop?or it is enough to use LACP?my configuration use etherchannel "trunk".
and do LACP prevent looping/broadcast storm?
and just to make clear about configuration my server are ESX with 4 interfaces (2 interfaces for vmkernel traffic and 2 interfaces for data traffic). The interfaces just in tagged vlan mode with load balance "route based on originating virtual port", no LAG configured on aruba switch side.
kindly need your advice. Thank You
Best Regards
