F5 LTM Interface flapping
The LTM interface keeps flapping.
This caused the LB to keep failover between active and standby status.
Unable to find the reason. Any suggestions or advise plz ?
Are you using network failover or serial cable?
If network then you should check the network cable and change it preferably. It is best practise to use two physical interfaces directly cabled between the two devices, in an LACP trunk. Use a single self-IP, configured for Default Port Lockdown. If you can, upgrade the software to at least 10.2.4. Bear in mind that serial failover does not work after v11.
