Which interfaces to use when TRUNKING.

I have an i4800 Big-IP and will be setting up LACP between it and my Cisco 3850's using the Gig SFP ports. Since the ports on the Big-IP are grouped together with 4 ports in each group. Is better to TRUNK with both port in the same group, or 1 port from each group. Some architectures have separate processors and buses to allow better performance and I cannot find any documentation on F5's site detailing this.

    You shouldn't see any significant performance gains or losses from using ports in one cluster versus one from each. They should connect to the same internal bus (I don't have a block diagram for this unit, so I can't 100% confirm that).

     

    I would suggest that you pick the ports that make the most sense from a cable management standpoint.
