## Symptoms

- * After issuing '`cpstop;cpstart`' commands on the Standby VSX cluster member, the output of '`cphaprob -a if`' command shows the following state of the Sync interface configured on Bond interface:

  * The state of Sync interface as '`UP`' in the context of VSX itself (VS0).
  * The state of Sync interface as '`DOWN`' for each Virtual System.

    vsid 0:
    ------
    Required interfaces: 3
    Required secured interfaces: 1
    
    wrp1       UP                    non sync(non secured), multicast
    bond2      UP                    non sync(non secured), multicast, bond High Availability
    bond4      UP                    sync(secured), broadcast, bond High Availability 
    
    vsid 2:
    ------
    Required interfaces: 3
    Required secured interfaces: 1
    
    bond4      DOWN            sync(secured), broadcast, bond High Availability
    wrp129     UP                    non sync(non secured), multicast
    wrp128     UP                    non sync(non secured), multicast
     
    vsid 7:
    ------
    Required interfaces: 4
    Required secured interfaces: 1
    
    bond4      DOWN            sync(secured), broadcast, bond High Availability
    wrp448     UP                    non sync(non secured), multicast
    wrp449     UP                    non sync(non secured), multicast
    wrp450     UP                    non sync(non secured), multicast 
    ```

* Reboot of Standby VSX cluster member resolves the issue.

## Cause

Sync interface is working normally. This is only a cosmetic issue - state of the Bond interface is not updated after issuing '`cpstop;cpstart`' commands.
