Yes you can create a link-aggregated trunk across multiple blades . I would create single trunk with all 4 ports and a VPC on nexus unless you need physical port segregation for your environments say you got two vCMPs and from network point of view you need them to be physically segregated.

 

Generally I'd consider :

 

  • Same number of ports from each blade
  • make total numbers even due to the frame-balancing algorithms
  • What blade are you using? if its 2250 and if you don't have SFP limitation I'd go for ports 1/1.1 , 1/1.5, 2/1.1 and 2/1.5. This gives you physical port resiliency on each blade

Farshad put it perfectly, I would do as he has said if possible regarding 4 port Trunk and 4 port VPC on the nexus.

 

If you do need physical port separation be careful with Spanning-Tree as the default mode on F5 is 'pass-through' so if any VLANs are shared you could end up with ports being put into blocking from the switch side.
