Configuring PPPoE Characteristics for a Profile

To configure PPPoE characteristics for a profile:

• Add an access concentrator name to the profile configuration.
  host1(config-profile)#pppoe acName CYM9876

  Use the no version to remove the AC name.

• Set up the router to offer to set up a session for the client, even if the router has insufficient resources to establish a session.
  host1(config-profile)#pppoe always-offer

  Use the no version to disable this feature.

• Prevent a client from establishing more than one session using the same MAC address.

  For a list of considerations to be observed when you use the duplicate protection feature for IWF PPPoE sessions, see Guidelines for Configuring Duplicate Protection for IWF PPPoE Sessions.

  host1(config-profile)#pppoe duplicate-protection

  Use the no version to disable duplicate protection.

• Enable packet trace logging on PPPoE dynamic interfaces created with this profile. Packet trace information is logged to the pppoeControlPacket log.
  host1(config-profile)#pppoe log pppoeControlPacket

  Use the no version to turn off packet trace logging.

• Configure the PPPoE application to send a PADM Message Of The Minute message. The recipient of the message is determined by the mode from which the command is issued.
  host1(config-profile)#pppoe motm string

  Use the no version to disable the command.

• Set the MTU using a combination of lower layer restrictions and controls.

  You can use the use-lower-layer keyword to use the lower layer interface value minus any PPPoE overhead. You can use the use-mtu-tag keyword to use the provided PPPoE mtu tag value.

  host1(config-profile)#pppoe mtu 1380

  Use the no version to restore the default value, 1494.

• Enable the router to capture and process a vendor-specific tag containing a remote circuit ID transmitted from a DSLAM device.

  Optionally, the router can use the remote circuit ID in place of either or both of the Calling-Station-Id [31] and NAS-Port-Id [87] RADIUS attributes to uniquely identify subscriber locations.

  host1(config-profile)#pppoe remote-circuit-id

  Use the no version to restore the default behavior, which is not to capture and process the remote circuit ID.

• Assign a PPPoE service name table to dynamic interfaces created with this profile.
  host1(config-profile)#pppoe service-name-table myServiceTable1

  Use the no version to remove the PPPoE service name table assignment.

• Specify the maximum number of PPPoE subinterfaces permitted on an interface, in the range 1–8000 (ERX routers) or 1–32,000 (E120 and E320 routers). On the ES2 10G ADV LM (E120 and E320 routers), you can have PPPoE subinterfaces in the range 1–32,000. The default value is 8000 (ERX routers) or 16,000 (E120 and E320 Broadband Services Routers) or 32,000 (ES2 10G ADV LM).
  host1(config-profile)#pppoe sessions 3000

  Use the no version to restore the default value, 8000 (ERX routers) or 16,000 (E120 and E320 routers) or 32,000 (ES2 10G ADV LM).

• Configure the PPPoE application to send the string to the new client created when the profile is dynamically attached to an IP interface.
  host1(config-profile)#pppoe url http://www.relevanturl.com

  Use the no version to disable the command.
