The setup I am working with has a Arris XB6 Modem/Wireless Router which sadly only has two gigabit ethernet ports. There are several devices that benefit from having a wired connection to the router including a NAS that supports link aggregation (LACP) to provide maximum bandwidth for the clients to utilize.
Unfortunately it's not possible to wire the NAS directly to the XB6 as this would take up all the available ports so instead I installed a Netgear GS308T switch to put downstream of the router. This is a "smart" switch that supports link aggregation - both static and LACP.
I connected both ports of the XB6 to the GS308T and configured a static LAG for both corresponding ports on the GS308T with STP enabled which seemed to work pretty well. (I also created a LACP LAG on two ports for the NAS which worked flawlessly).
I thought all was well until I tested some of the other downstream wired devices and noticed that some weren't able to get DHCP addresses and others were complaining about duplicate addresses on the network. Does anyone have any idea why this might be happening? Is it simply a case that the XB6 doesn't play nice with Link Aggregation or is there perhaps something I can do to make this work?
It feels like I am close as some of the devices are working fine and the switch isn't detecting any loops so if anyone had any ideas that would be much appreciated. Thanks in advance!
