Trunk with F5

Hi Ajay,

 

 

Since you have redundant units you could connect LTM A 1.1 and 1.2 to switch A and LTM B 1.1 and 1.2 to switch B. Cross connecting 1.2 is not going to buy you anything because if you loose one of the switches then you lose one LTM and one link from the surviving LTM. If you connect them the way I stated then you if you loose an LTM or a switch you simply failover keeping 2 links up since they are active/standby.

 

 

Hope this helps

If you are creating etherchannels on the Cisco switches, both pieces of cable have to go to the same BIG-IP.

 

 

If that isn't what you are doing, then you shouldn't put 1.1 and 1.2 on the BIG-IP in a trunk, just assign them both to the same vlan, make sure they are assigned the same vlan on each switch, make the trunk between switches an L2 bridge and let spanning tree do the rest.
