Customized Update Source
Aside from the OfficeScan server, clients can update from custom update sources.
Custom update sources help reduce client update traffic directed to the OfficeScan
server and allows clients that cannot connect to the OfficeScan server to get timely
updates. Specify the custom update sources on the Customized Update Source List,
which can accommodate up to 1024 update sources.
Tip: Trend Micro recommends assigning some clients as Update Agents and then adding
them to the list.
To configure the customized updated source list:
PATH: UPDATES > NETWORKED COMPUTERS > UPDATE SOURCE
1. Select Customized Update Source and click Add.
2. In the screen that displays, type a range of client IP addresses that will receive
updates from an update source.
3. Specify the update source. You can select an Update Agent if one has been assigned
or type the URL of a specific source.
4. Click Save.
5. Edit an update source by clicking the IP range link. Modify the settings in the
screen that displays and click Save.
6. Remove an update source from the list by selecting the check box and clicking
Delete.
7. To move an update source, click the up or down arrow. You can only move one
source at a time.
After you have set up and saved the list, the update process proceeds as follows:
1. A client updates from the first entry on the list.
2. If unable to update from the first entry, the client updates from the second entry,
and so on.
3. If unable to update from all entries, the client checks if the option Update from
OfficeScan server if all customized sources are not available or not found is
enabled. If enabled, the client updates from the OfficeScan server.
