Using the Symantec Management Agent's Bandwidth Throttling feature to decrease the traffic caused by the Symantec Management Agent (SMA) going through the network.
IT Management Suite 8.x
When you enable bandwidth throttling, you must also add and configure at least one throttling period.
You can create and modify the throttling periods that you want to use.
You can specify any number of throttling periods. If two or more periods overlap, the lowest throttling value is used.
For each throttling period, you can configure the following options:
On ULM agents, the package download speed can be higher than expected even when throttling is enabled. This is because, during the first 10 seconds, the ULM agent downloads a package with the maximum speed and measures the bandwidth during this time. After 10 seconds, the specified throttling limits are applied for the next 180 seconds, and then the agent measures the bandwidth again.
