Managed Interface has Status UNKNOWN after domain restarted.
All Supported Smarts releases
The interface status is UKNOWN since the interface on the router has not yet been SNMP polled by Smarts after the restart. The first SNMP polls after a restart will require a few minutes before all the SNMP responses will be inserted in the status property for managed interfaces.
None. This is expected behavior
If viewing the interface status property in the Smarts AM administration console, be sure to hit refresh button every thirty seconds until the status property updates from an UNKNOWN to an up or down value. The administration console properties view does not automatically update once open and left on a specific object.
