According the documentation, SX550 support 2 interfaces agregation to compose a stacking LAG (increasing BW between the switches)...
But the documentation mention that only interfaces XG1-XG2 and XG3-XG4 can be used for this purpose... that's not SFP interfaces on the SX550X-24 model, and i've planned to use SFP-H10GB-CU1M to connect the switches...
Does it means it's impossible to use 2 SFP interfaces (11-12 or 23-24) to connect 2 SX550X-24 in a stack to obtain a 20Gbps stack link ?
