Actually, I have tried both switchport mode access and switchport mode trunk, the result is similar.

 

 

While setting the correct VLAN no for external and internal interface on F5 provide much different result. Actually I have untagged the interface and I thought it shouldn't affect anything. But the result is not, when I disregard the VLAN no (does not match with cisco 2960), the network even goes down for a while some times.

 

 

 

It seems like the F5 participate in VLAN stuff even in my route mode setup scenario.

 

 

 

Anyway, do you think I better try to include external VLAN (10) and internal VLAN (4093) on the failover VLAN ? That means failover VLAN include 10, 4092 and 4093 also. For I don' have much idea over here, coz the fail over interface is a fibre direct connection.
