The VoIP Quality assessment requires you to select the locations on the network where simulated VoIP calls will run. These locations, or , are computers that have NetIQ Performance Endpoint software installed. You should install Performance Endpoints now, if you have not done so already. The endpoints are not required for the Network Inventory or Utilization Assessment or for Bandwidth Modeling. For more information, see Section 1.4, NetIQ Performance Endpoints.
As a first step in setting up a VoIP Quality assessment, you can instruct Vivinet Assessor to discover all the endpoints on the network and add them to a list. Then when you design your VoIP Quality assessment in the Design view, you simply click and drag endpoints from the list onto a network diagram. The ’ network addressing information is automatically entered into the database as they are discovered.
NOTE:Perform a Network Inventory before discovering Performance Endpoints That way, endpoint discovery can use the same IP network address ranges you already configured for the Network Inventory. For more information, see Section 3.0, Task 1: Performing a Network Inventory.
To discover endpoints installed on your network:
Expand the Assess VoIP Quality view tab and click the Discover Endpoints tab.
The ranges of IP network addresses you entered when setting up the Network Inventory appear in the Performance Endpoint Discovery Ranges table. By default, all are selected for endpoint discovery scanning.
To exclude any ranges from discovery, clear the boxes in the “Use in Discovery” column.
To add a new range of IP network addresses, click Add.
Click Activate Discovery. When discovery is complete, the Summary of Latest Discovery panel provides the following information:
|
Field |
Description |
|---|---|
|
Status |
The current state of endpoint discovery scanning. Once discovery is complete, the Status reads, “Discovery complete." |
|
Start time |
The time discovery scanning became active. |
|
End time |
The time discovery scanning ended. |
|
Number of addresses scanned / # expected |
How many endpoint discovery scans have been performed of the total number of scans scheduled to be performed. The second value is estimated from the number of addresses in the IP network address range(s) selected for endpoint discovery scanning. |
|
Number of endpoints found |
The number of endpoints already discovered and added to the Endpoint and Group List in the Design view. |
|
Number of errors encountered |
The number of errors that occurred during endpoint discovery scanning. Click View Error Log to view information about the errors and get help for avoiding them in future scans. |
After endpoint discovery is complete, click the Design view tab to see the complete list of endpoints available for the VoIP Quality assessment.
