Selecting the Phones

Associated with an

NBX Call Processor

■IP Ping Service: 3Com Network Director checks the availability of the phone using the ICMP Ping echo. Note that this monitor is only available for IP phones.

Because 3Com Network Director polls the NBX Call Processor rather than the phone itself to retrieve the phone status, even phones with no IP address assigned can be monitored.

If the NBX Call Processor is not responding, the whole phone network will be unavailable. As a result, all monitored phones will become red, indicating high stress, on the map.

Monitoring a Line Card

By default, line cards will not be monitored on your network, because they are not considered to be core devices.

To start monitoring a line card, select the icon for it on the map, and use the Monitoring > Start Monitoring menu option.

The only monitor available for a line card is the IP Ping Service. This monitor is only available if an IP address was configured for the line card.

If a line card does not have an IP address assigned, the Monitoring > Start Monitoring menu option will be disabled.

3Com Network Director allows you to highlight the phones that are managed by a given NBX Call Processor.

To do so, right-click on the NBX Call Processor icon on the map and click the Select Related Phones option, as seen in Figure 420.

The position of phones on the map does not necessarily mean that they are managed by the closest NBX Call Processor.
