# Configuring PPPoE Service Name Tables

To configure PPPoE service name tables on the router:

1. Create the PPPoE service name table.
2. (Optional) Add entries to populate the PPPoE service name table.

   You can:

   - Configure specific service names to represent custom values.
   - Specify a nondefault action for the empty service name entry.
   - Specify a nondefault action for the unknown service name entry.
3. Enable the PPPoE service name table for use with a static or dynamic interface.

The following sections describe how to perform these tasks.

## Creating and Populating PPPoE Service Name Tables

To create and populate a PPPoE service name table on the router:

1. From Global Configuration mode, create a PPPoE service name table by assigning it a name.
   host1(config)#pppoe-service-name-table myServiceTable1

   This command accesses PPPoE Service Name Table Configuration mode and builds a default PPPoE service name table named myServiceTable1. The table contains two entries: an empty service name entry associated with the default action, terminate; and an unknown service name entry associated with the default action, drop as shown in Table 25. This table directs the router to respond to all PADI requests containing an empty service name tag; and denies requests that contain a service name tag that has not been configured in the service name table.

   Table 25: Default PPPoE Service Name Table

   Service Name | Action
   --- | ---
   “ ” | Terminate
   unknown-service-name | Drop

2. (Optional) From PPPoE Service Name Table Configuration mode, create entries to populate the PPPoE service name table.

   You can configure up to 16 specific service name entries per table, in addition to the empty and unknown service name tags.

   host1(config-pppoe-service-name-table)#service myISPService action drop host1(config-pppoe-service-name-table)#service myQOSClass1 action terminate host1(config-pppoe-service-name-table)#service myQOSClass2 action drop host1(config-pppoe-service-name-table)#service myQOSClass3 host1(config-pppoe-service-name-table)#service empty-service-name action drop host1(config-pppoe-service-name-table)#service unknown-service-name action terminate

   These commands build the PPPoE service name table shown in Table 26. This table directs the router to send a PADO packet in response to all PADI requests containing the myQOSClass1, myQOSClass3, empty service name tags, and unknown service name tag. The router is directed to drop all PADI requests containing the myISPService or myQOSClass2 or the empty service name tags.

   Table 26: PPPoE Service Name Table with Entries

   Service Name | Action
   --- | ---
   myISPService | Drop
   myQOSClass1 | Terminate
   myQOSClass2 | Drop
   myQOSClass3 | Terminate
   “ ” | Drop
   unknown-service-name | Terminate

3. Exit PPPoE Service Name Table Configuration mode.
   host1(config-pppoe-service-name-table)#exit
4. (Optional) Use the appropriate show command to verify the creation of the PPPoE service name table and entries.
   host1(config)#show pppoe-service-name-table name myServiceTable1
5. (Optional) Repeat Steps 1 through 4 to configure additional PPPoE service name tables on the router.

pppoe-service-name-table

- Use from Global Configuration mode to create a PPPoE service name table.
- You can create a maximum of 16 PPPoE service name tables per E Series router.
- Specify a table name of up to 31 alphanumeric characters.
- This command accesses PPPoE Service Name Table Configuration mode, which enables you to configure entries for the PPPoE service name table.
- Example
  host1(config)#pppoe-service-name-table myServiceTable1
- Use the no version to remove the specified PPPoE service name table from the router.
- See pppoe-service-name-table.

service

- Use to add service name tags to the PPPoE service name table.
- Each PPPoE service name table includes one empty service name tag, one unknown service name tag, and can optionally include up to 16 additional custom service name tags. An empty service name tag is used to represent any service. An unknown service name tag is used to represent a service that has not been configured in the PPPoE service name table. A custom service name tag is used to represent a specific service.
- To modify the action associated with an empty service entry, use the empty-service-name keyword with the action keyword. This directs the router to drop PADI requests from the PPPoE client. The default action for an empty service name entry is terminate.
- To include a custom service entry, specify a serviceName of up to 31 alphanumeric characters. Use the optional action keyword with the service command for a custom service entry to specify that the router either drop or terminate PADI requests from the PPPoE client. The default action for a custom service entry is terminate.
- To modify the action associated with an unknown service entry, use the unknown-service-name keyword with the action keyword. This directs the router to terminate (allow) PADI requests from the PPPoE client. The default action for an unknown service name entry is drop.

  The default action for the unknown service name entry depends on the configuration of the service name table. If all the services in the service name table are configured to terminate, the default action of the unknown service name tag is drop. If all the services in the service name table are configured to drop, the default action for the unknown service name tag is terminate. If both terminate and drop are configured, the default action for the unknown service name tag is drop.

- Example 1– Includes a custom service entry in the PPPoE service name table. The associated action for this service tag is terminate. This is the default action when you add a custom service entry without using the optional action keyword.
  host1(config-pppoe-service-name-table)#service myISPService
- Example 2 – Includes a custom service entry in the PPPoE service name table. The associated action for this service tag is drop. Use the optional action keyword with the service command to associate an action with the custom service entry.
  host1(config-pppoe-service-name-table)# service myQOSClass2 action drop
- Example 3 – Includes an unknown service name entry in the PPPoE service name table. The associated action for this service tag is terminate. Use the action keyword with the service command to associate an action with the unknown service name entry.
  host1(config-pppoe-service-name-table)# service unknown-service-name action terminate
- Example 4 – Includes an empty service name entry in the PPPoE service name table. The associated action for this service tag is drop. Use the action keyword with the service command to associate an action with the empty service name entry.
  host1(config-pppoe-service-name-table)#service empty-service-name action drop
- Use the no version to remove the custom service name tags from the PPPoE service name table or restore the default action for the empty and unknown service name tags.
- See service.
