For VIPRION® platforms, F5 Networks strongly
recommends that you create a trunk for each of the BIG-IP® system
internal and external networks, and that each trunk contains interfaces from all slots in the
example, a trunk for the external network should contain the external interfaces of all blades
in the cluster. Configuring a trunk in this way prevents interruption in service if a blade in
the cluster becomes unavailable and minimizes use of the high-speed backplane when processing
Also, you should connect the links in a trunk to a vendor switch on the relevant network.
When processing egress packets, including those of vCMP® guests, the BIG-IP system uses trunk member interfaces on local blades whenever
possible. This behavior ensures efficient use of the backplane, thereby conserving backplane
bandwidth for processing ingress packets.
