If the connection speed falls below the value that you specify, the bandwidth throttling settings that you specify are applied.
Table: Throttling Periods settings
Add throttling period
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 set the following:
The start time and duration of the throttling period.
The amount of throttling, where the numerical value is either a percentage of the maximum download rate, or a specific download rate in KB/sec.
Deletes the selected throttling period from the list.
The time zone to use for defining the throttling periods.
The available time zones are as follows:
Use agent time
The times are specified without time zone information, and are applied at the local time at each managed computer. Throttling periods start and end at different times depending on the time zones of the managed computers.
Use server time
The times are specified with time zone information, where the time zone offset is that of the server's time zone where the policy is defined. The throttling periods start simultaneously irrespective of time zones, and are compensated for daylight saving.
This option ensures that throttling periods are always coordinated with the specified local time on the server where the policy is created.
Coordinate using UTC
The times are specified with time zone information, where the time zone offset is 0. The throttling periods start simultaneously irrespective of time zones and are not affected by daylight saving.
Table: Multicast Configuration settings
Allow Symantec Management Agents to use multicast for downloading packages
By default the Symantec Management Agent should use multicast when downloading packages
If multicast is set as the default for downloading packages in the Global Agent Settings policy, this option lets you turn it off. However, individual packages may override this setting.
If the Global Agent Settings policy has multicast turned off, you cannot turn it on with this option.
Maximum master sessions per computer
The maximum number of concurrent sessions for which a Symantec Management Agent can be the master.
The default value is 2 for new policies and for most of the default targeted agent settings policies that are supplied with Notification Server. The exception is the All Package Servers policy, which has a default value of 10. This is the suggested default for package servers.
Minimum receiving computers per session
The minimum number of Symantec Management Agents (excluding the master) that must join the session before package multicasting can proceed.
Wait time to begin session
The maximum time to wait for the minimum number of Symantec Management Agents (excluding the master) to join the session, before the session times out.
This value can be defined as a percentage of the Download new configuration interval on the General tab, or in minutes.
The default value is 50% of the Download new configuration interval.
The larger the value, more agents will join the session and reduce bandwidth utilization on the local segment, but it will take longer for the package to arrive. Configure this value higher than the minimum time to start multicast (around 10 minutes).
If a session times out, the Symantec Management Agents that were members of the session will attempt to download the package again through multicast, until the Maximum transmission attempts per package value is reached.
Number of receiving computers required to begin session before wait time has expired
The number of Symantec Management Agents (excluding the master) that must join a session to enable multicasting to begin.
The default value is 100.
This setting cannot be less than the value that you specified for Minimum receiving computers per session.
This setting can be used to override the wait time when enough agents have joined the session to represent significant bandwidth savings. The wait time is specified in the Wait time to begin session field.
Maximum bandwidth to use for multicasting
The maximum bandwidth that multicasting can use per package.
The default value is 125 Kbytes/sec.
Maximum transmission attempts per package
The maximum number of times that the Symantec Management Agent may attempt to receive the same package through multicast. If all attempts fail, the agent reverts to the normal package download procedure.
The default number is 3.
Maximum sessions per physical subnet
Specifies the maximum number of multicast sessions that can occur concurrently per physical subnet.
The default number is 10.
Disable multicast for packages smaller than
Specifies the minimum package size that may be downloaded using multicast.
The default size is 512 KB.
