link aggregation with a dual port modem but only one 2.5 gig port on router?(ax6000)
I have Comcasts 1 gig plan. They have recently upgraded us to a 1.2 gig plan. My modem, a Arris SB8200, supports up to 2 gb/s but uses two different ports with link aggregation. I have enabled link aggregation on the modem. The AX6000 has one 2.5 gig/port, but also states it supports link aggregation on ports 2 and 3. How can I configure the AX6000 to use both of my ports on my modem to get past the 1 gig speed barrier? Or am I going to need to find a modem that has one 2.5 gig port only? Please advise.. I'm figuring we can use only use the 2.5 gig port on the router to connect to a modem?.
