Table Structure

Each entry, or row, in a PPPoE service name table consists of the following components:

• Service name tag—Service name tags specify the client services that an AC supports. Every PPPoE service name table includes one empty service name tag, which is a tag of zero length used to represent any service. In addition, you can configure up to 16 specific service name tags per table to specify custom values such as an ISP name or class of service.
• Action—Each service name tag has an associated action: terminate (the default action) or drop. For the empty service name tag, you can specify that the router ignore (drop), rather than respond to (terminate), all PADI requests containing the empty service name tag. By contrast, when you configure a specific (custom) service name tag, you cannot specify the action; the default action, terminate, is always used.

For example, Table 15 shows a PPPoE service name table containing four entries: an empty service name tag (“ ” ) associated with the drop action, and three specific service name tags. Note that the only action currently supported for a specific service name tag is terminate.
