      I just tried to connected F5(40G) to Cisco(10G * 4ea)

      F5 interface not working [40G port status is down but cisco side is up] when I tried to connected 40G port to 10G * 4ea using break out cable

      (I guess this is relate to speed negotiation)

      So, I try to connect to 10G *4ea using trunk

      [ F5 40G port configure trunk and cisco port configure trunk ]
