I am facing a weird issue on one of the physical nodes, even though interfaces are showing up all trunk groups are down, including HA which is back to back connectivity between both the appliances is down.
Any advise to fix this issue, i tried disabling/enabling the interfaces and rebooted the appliance as well. It didn't work
it's difficult to say without know the platform and the BIG-IP version. Did you recently make changes to the trunk configuration or update the a newer BIG-IP version?
* Are ports working if you use them without being part of a trunk?
* Check for know bugs with your platform and BIG-IP version.
* Reboot and run End-User Diagnostic
* Open a case (if this is prod environment, you anyhow want professional help and not rely on community support.)
