I have 2 arista 7060cx using a breakout cable going to 1 7280sr2k. I’m using 8 ports from each 7060 breakout to the 7280. The ports will not come up. I have configured 1st lane on 7060s with speed forced speed 100gfull. On the 7280, I have each lane configured at speed forced 25gb. The port channel will not come up. I am using port 33-48 on 7280sr2k which are 25 gig ports. I have attached a pic of the qsfp.
