unless there is an IP address (either Alpha’s or Charlie’s) entered in Bravo’s Service and
alarm discovery area.
5. The discovery process will result in all devices and services on Subnet B automatically
registering with Charlie’s Lookup Service. If a client PC opens iC Navigator from Charlie, all
Subnet B devices and services will be visible.
6. If this client PC has access to Subnet A (e.g. via VPN), it can access Alpha’s iControl Startup
page from a Web browser, and download iC Navigator (or any client application). The
application knows about the Lookup Service on Alpha, and so the client PC will be able to
see all devices and services registered on both Alpha and Bravo. Similarly, downloading an
application from Charlie would make all of the devices and services on Subnet B visible.
However, in order for that same client PC to be able to see services and devices from both
Subnet A and Subnet B, the IP addresses of both Alpha and Charlie, must be typed in each
other’s Service and alarm discovery areas.
Examples: Alarm Publication Lookup Scenarios
Example 1 — Publishing Densité Alarms to all GSMs within the Local Subnet
If you want your local Application Server’s Densité alarms to be visible only to the GSMs within
the local subnet, you can leave the Alarm publication table of the local Application Server
unpopulated.
IMPORTANT: System behavior
If the Service and alarm discovery table of Application Servers is empty,
client applications on the local Application Server can see services and
alarms coming from the local GSM and all active GSMs on Application
Servers within the subnet.
Note: The order in which the IP addresses are typed is not important.
