Configuring F5 using Trunking

Hi All,

 

 

I just opened a brand new F5 LTM box. I am ready to configure them with our Cisco switches.

 

 

I am planning to do create a trunk using 4 ports for the front end and 4 ports on the backend to aggregate 4 gigE ports.

 

 

For the front end, I just want to tag only one vlan but for the backend I want to tag multiple vlans since the servers that needs load balancing are on different vlans.

 

 

I found a solution that explains how to aggregate links and tag one vlan. How do I tag multiple vlans on a trunk?

    On each VLAN that you want to have on the backend trunk just add the trunk interface (whatever you named the trunk) to the Tagged column.

    Thank you. I think I did it correctly.

     

     

    How about the spanning tree configuration? What is the difference between STP being disabled or pass through? Does disabled mean stop sending/receiving BPDUs? Pass through is probably let the BPDUs go through the device.

     

     

    I want the upstream swithces to take care of the loop detection/prevention and I do not want the F5s to send/receive BPDUs. In this case, do I disable it or set it as a "pass through"?

     

     

    thanks,
