Assigning an ACI/ARI Pair to a Service Name and Configuring the Action Taken When the Client Request Includes ACI/ARI Information

You can configure up to 8000 agent circuit identifier/agent remote identifier (ACI/ARI) pairs per PPPoE service name table, distributed in any combination among the named, empty, and any service entries in the service name table. You can optionally configure the action taken by the PPPoE underlying interface when it receives a PADI packet that includes a service name tag and the vendor-specific tag with ACI/ARI information that matches the ACI/ARI pair that you specify.

You can use an asterisk (*) as a wildcard character to match ACI/ARI pairs, the ACI alone, or the ARI alone. The asterisk can be placed only at the beginning, the end, or both the beginning and end of the identifier string. You can also specify an asterisk alone for either the ACI or the ARI. You cannot specify only an asterisk for both the ACI and the ARI. When you specify a single asterisk as the identifier, that identifier is ignored in the PADI packet.

For example, suppose you care about matching only the ACI and do not care what value the ARI has in the PADI packet, or even whether the packet contains an ARI value. In this case you can set the remote-id-string to a single asterisk. Then the interface ignores the ARI received in the packet and the interface takes action based only on matching the specified ACI.

To indicate that it can service the client request, the interface returns a PADO packet in response to the PADI packet. By default, the interface immediately responds to the request; this is the terminate action. Alternatively, you can configure the drop action to ignore (drop) the PADI packet, or the delay action to set a delay between receipt of the PADI packet and transmission of the PADO packet.
