## Symptoms

- * Bridge slave interfaces are configured according to [sk108121](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk108121) to enable LSP.  

  Slave Interfaces status will be down if the interface(s) are jacked out and wait for 30 seconds and then jacked in.  

  Then the interfaces will remain in down state unless manually reboot the appliance.

* Slave Interfaces status remain up if the interface(s) are jacked out and jacked in within 30 seconds.

* Similiar logs are found in /var/log/messages:
