## Symptoms

- * SmartView Monitor shows:  
  `ClusterXL - Error: Refer to the Notification and Interfaces tables for information about the problem`  

  When clicking on '`More...`', under '`Problem Notification Table`' normal operational interface shows up as '`Disconnected`'.  

* Output of '`cphaprob state`' command shows the local member as '`Down`'.  

* Output of '`cphaprob list`' command shows that the state of '`Interface Active Check`' Device is '`problem`'.  

* Output of '`cphaprob -a if`' command shows the problematic interface as '`Disconnected`'.  

* Output of '`ifconfig -a`' command shows the problematic interface as '`UP`' and with assigned IP address.

## Cause

One of the possible causes is that by mistake, the problematic interface has been configured as '`Disconnected`' via `$FWDIR/conf/discntd.if` file (per [sk30060](http://supportcontent.checkpoint.com/solutions?id=sk30060)).
