The default action associated with the unknown service name tag depends on the
PPPoE service name table configuration. If all the services in the table are configured
to drop, the default action for the unknown service name tag is terminate. If all the
services in the table are configured to terminate, the default action for the unknown
service name tag is drop. If both terminate and drop are configured for services in the
table, all unknown service name tags are dropped by default.

Features

PPPoE service name tables enable an AC, such as an E Series router, to support multiple
service name tags in addition to the empty service name tag and the unknown service
name tag. You can configure up to 16 PPPoE service name tables per E Series router to:
Define the set of service name tags (empty service name, custom service name, and
unknown service name) that the router advertises in the PADO packets sent to PPPoE
clients.
Control whether the router responds to (terminate) or denies (drop) PADI requests
based on the action associated with the service name tags.
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.
You can add three types of service name tags to the PPPoE service name table: empty
service name, custom service name (serviceName), and unknown service name. Every
PPPoE service name table includes one empty service name tag and one unknown
service name service tag. An empty service name tag is a service tag of zero length
that is used to represent any service. An unknown service name service tag is used to
represent a service tag that has not been configured in the service name table. In
addition to these two tags, you can configure up to 16 custom service name tags per
table.
Action—Each service name tag has an associated action: terminate (the default action)
or drop. For empty service name and unknown service name entries, you can use the
action keyword with the service command to modify the default action associated
with the service. For custom service name (serviceName) entries, using the action
keyword with the service command is optional. The default action for a custom service
tag entry is terminate.
For example, Table 19 on page 374 shows a PPPoE service name table containing five
entries: three custom service name tags, two associated with the terminate action and
one associated with the drop action; an empty service name tag (" " ) associated with
the drop action; and an unknown service name tag associated with the drop action.
