Essentially, this creates a baseline for the standby server. The standby server will have the complete device list
and all the configurations that are identical to the active server. This also means that the standby server will poll
the network in exactly the same way as the active server.
If you want to reduce the impact of polling on network bandwidth, do the following:
Step 1. Increase the polling interval to a very large value (1 hour) to reduce impact on network bandwidth.
You can do this by going to Administration > Polling Parameters, selecting each group, and editing the
polling interval values.
Step 2. Go to Administration > Notifications > Notification Criteria.
Step 3. Select all notification criteria and select Suspend.
Step 4. Go to Administration > Diagnostics Tests > Synthetic Tests. For each test, select Stop.
This will stop the synthetic tests.
Step 5. Go to Administration > Diagnostics Tests > Phone Status Tests.
You will see a list of configured tests.
Step 6. For each test, click Edit and configure the schedule to run between “00:00” to “00:00.”
This essentially stops the test.
Step 7. Suspend monitoring of SRST routers used in SRST tests.
To do this:
a. Go to Administration > Polling and Thresholds > SRST Operations.
You will see a list of SRST tests configured.
b. Make a note of all the target routers.
c. Go to Administration > Device Management > Device Configuration.
You will see an overview of all managed devices.
d. Click Monitored Devices.
e. Click the SRST router IP address in this report.
The Detailed Device View is launched.
f. In this screen, suspend the device.
This will automatically stop the SRST tests.
Continuous Data Synchronization
After the active server and the standby server are operating, any changes to the active server must be propagated
to the standby server. Different kinds of data that can change, and recommendations for replication, are listed
below.
Device List
Changes to the device list can be propagated by using a central DCR. There are two possibilities:
●
Central LMS server as the source of the device list for both active and standby In this case, the LMS server
acts as a master repository of devices, which pushes any additions or deletions to the device list to the
active and standby servers.
