LTM failover itself

LTM 1600 in pair getting failover itself without any error. and every day they are bouncing here and there. is it normal? or configuration issue?

 

Update:

 

I was reading about VLAN fail-safe, look like something interesting there. I have created VLAN but nothing connected on that VLAN. do you think because of that its getting failover?

 

Q1. Does fail-safe by default enabled on ALL VLAN?

 

Q2. Can i disable fail-safe on specific VLAN?

 

Q3. How do i find out it is fail-safe causing issue? any logs etc..?

    You enable failsafe on the vlans of your choosing. My advice would be to configure something in the vlan as it needs to see traffic and/or generate its own traffic to known objects in the vlan. Without a node at least I'm not surprised you may have issues.

     

    Hope this helps,
