Re: Need help with LACP Trunking on 4948 switch

I assume you've set your vlan's to the new trunk to send traffic through the bundle. Can you post your bigip_base.conf with relevant data?

I have this same config in multiple environments, one with an 8900 as well. I'll share that section when I'm near a computer again.
