I have two S5720 switch, and they connect to each other through a eth-trunk, to make sure the eth-trunk keeps working when few physical links donw, so I add more physical links than needed, in other words, there are physical redundancy. for example, I added four links and only two of them are in used, the rest are standby, but there are problems, the choosen interfaces are not expected one, though I configured lacp priority under the interface view. below is the configuration. when finished the configuration, I expect interface g0/0/3 and g0/0/4 as the main using, and g0/0/1, g0/0/2 are standby, but on the contrary, g0/0/1 and g0/0/2 are the main using, and g0/0/3, g0/0/4 are standby. what's the problem?
