About Site Maintenance

Site maintenance is the management of sites, subnets, and site services in your organization. You can manage your computers according to site and subnet, which lets you control groups of computers while you minimize bandwidth consumption. A site is typically a physical location in your organization (such as a particular building, or a level of a building). A subnet is a range of logical addresses on your network.
Under normal operating conditions, each package server or task server services only the Symantec Management Agents that exist within the assigned sites. If no sites have been defined, all site servers are available to service all Symantec Management Agents (although this method is not recommended).
If no sites are defined for a package server or a task server, Notification Server uses the following rules:
  • Notification Server first tries to find any site servers on the same subnet as the requesting computer. If any are found, these site servers are returned to the Symantec Management Agent.
  • If no site servers are in the same subnet as the requesting computer, all site servers are returned to the Symantec Management Agent.
You can assign site servers to sites by using the following methods:
  • Assign the subnet that contains the site server to a site.
  • Assign the site server to a site.
  • Use Active Directory import to perform the task.
    Active Directory import overrides any subnets and sites that conflict with it. For example, if you manually assign subnets to a site that conflicts with the data from Active Directory import, the Active Directory information is used.
After the list of available site servers is returned to the Symantec Management Agent, the agent chooses the most suitable site server.
Site servers and managed computers may have multiple NICs and IP addresses; therefore, they may belong to more than one site through subnet assignment.
