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.

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 a single empty service name entry associated with the default action, terminate, as shown in Table 18. With no further service name entries, this table directs the router to respond to all PADI requests containing an empty service name tag.

Table 18: Default PPPoE Service Name Table 

Service-Name	Action
" "	Terminate

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, or modify the action for the empty service name tag.

host1(config-pppoe-service-name-table)#service myISPService

host1(config-pppoe-service-name-table)#service myQOSClass1

host1(config-pppoe-service-name-table)#service myQOSClass2

host1(config-pppoe-service-name-table)#service empty-service-name drop

These commands build the PPPoE service name table shown in Table 19. This table directs the router to send a PADO packet in response to all PADI requests containing the myISPService, myQOSClass1, or myQOSClass2 service name tag, and to ignore (drop) all PADI requests containing empty service name tags.

Table 19: PPPoE Service Name Table with Entries 

Service-Name	Action
"myISPService"	Terminate
"myQOSClass1"	Terminate
"myQOSClass2"	Terminate
" "	Drop

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.

service

• Use to add a specific service name tag to a PPPoE service name table, or to modify the action for the empty service name tag in a PPPoE service name table.
• Each PPPoE service name table includes one empty service name tag, and can optionally include up to 16 additional specific service name entries.
• For each specific service name tag that you configure, assign a name of up to 31 alphanumeric characters.
• You cannot configure the action for a specific service name tag; the default action, terminate, is always used.
• For an empty service name tag, you can specify that the AC, such as an E-series router, ignore (drop), rather than respond to (terminate), all PADI requests from the client that contain an empty service name tag.
• Examples

host1(config-pppoe-service-name-table)#service myISPService

host1(config-pppoe-service-name-table)#service empty-service-name drop

• Use the no version to restore the default action, terminate, for an empty service name tag, or to remove the specified non-empty service name tag from the PPPoE service name table.

Enabling PPPoE Service Name Tables for Use with Static Interfaces

To enable a PPPoE service name table for use with a static interface, assign the service name table to the PPPoE major interface.

PPPoE over ATM Configurations

To enable a PPPoE service name table for use with a static interface in PPPoE over ATM configurations:

host1(config-subif)#atm pvc 10 100 22 aal5snap

4. Select PPPoE as the encapsulation method on the interface. This command creates the PPPoE major interface.

host1(config-subif)#encapsulation pppoe

5. Assign the PPPoE service name table to the PPPoE major interface.

host1(config-subif)#pppoe service-name-table myServiceTable1

PPPoE over Ethernet Configurations

To enable a PPPoE service name table for use with a static interface in PPPoE over Ethernet configurations:

1. Configure a Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet physical interface.

host1(config)#interface fastEthernet 4/1

2. Select PPPoE as the encapsulation method on the interface. This command creates the PPPoE major interface.

host1(config-if)#pppoe

3. Assign the PPPoE service name table to the PPPoE major interface.

host1(config-if)#pppoe service-name-table myServiceTable1

interface fastEthernet

• Use to select a Fast Ethernet interface.
• Example

host1(config)#interface fastEthernet 4/1

interface gigabitEthernet

    interface tenGigabitEthernet

• Use to select a Gigabit Ethernet interface or a 10-Gigabit Ethernet interface.
• For information about specifying the Gigabit Ethernet or 10-Gigabit Ethernet interface or subinterface, see interface gigabitEthernet and interface tenGigabitEthernet on 329.

pppoe service-name-table

• Use from Interface Configuration mode to assign a PPPoE service name table to a PPPoE major interface for use by a static Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface.
• Specify the name of the PPPoE service name table configured with the pppoe-service-name-table command from Global Configuration mode.
• Example

host1(config-if)#pppoe service-name-table myServiceTable1

Enabling PPPoE Service Name Tables for Use with Dynamic Interfaces

To enable a PPPoE service name table for use with a dynamic interface, add the service name table to a profile that is dynamically assigned to the interface.

For complete details, see Configuring a Dynamic Interface from a Profile in Chapter 15, Configuring Dynamic Interfaces.

To enable a PPPoE service name table for use with a dynamic interface:

1. Create a profile by assigning it a name.

host1(config)#profile baseProfile

2. Assign the PPPoE service name table to the profile as a PPPoE characteristic.

host1(config-profile)#pppoe service-name-table myServiceTable1

3. Exit Profile Configuration mode.

host1(config-profile)#exit

4. Configure a physical interface.

On ERX-7xx models, ERX-14xx models, and the ERX-310 router:

host1(config-if)#interface atm 3/0.1

5. Configure an ATM PVC by specifying the VCD, the VPI, the VCI, and the encapsulation type.

host1(config-subif)#atm pvc 10 100 22 aal5snap

6. Apply the profile to the interface.

host1(config-subif)#profile pppoe baseProfile

7. Enable the PPPoE dynamic encapsulation type.

host1(config-subif)#auto-configure pppoe

• This command causes the layers above ATM 1483 to become dynamic.
• Select pppoe as the dynamic next upper interface type.
• Example

host1(config-subif)#auto-configure pppoe
