Advantages and Disadvantages to trunk LTMs

I was initially concerned with isolating the traffic between client and web servers.

 

 

With trunking on front and back of the F5 I thought that the clients could bypass the F5 on our main switch by going directly to the servers since nothing would be forcing them through the F5. But, my final working design now puts the F5s in trunks on the front and back end but only through a dedicated physical switch on each side. That's the only place where the trunks will be configured. This way I can gain all the benefits of trunking but not cause any issues on the actual network.

 

 

Any gotchas with that?
