Configuring PADM Messages

You can configure PPPoE to issue and display a PPPoE Active Discovery Message (PADM). The PADM message is a control message that servers send to clients. The clients may act on the control message, but are not required to do so. There are two types of PADM messages:

Message of the minute (MOTM)—Informs clients of interesting system information
URL—Typically spawns an Internet browser with the specified URL as the initial page

You can configure the router to send PADM messages as follows:

Send MOTM messages to all clients connected to the router.
Send MOTM and URL messages to all clients connected to a subinterface.

Configure profiles to send MOTM and URL messages to new clients created when the profile is dynamically attached to an IP interface.

Note: You can use the pppoe motm command at three different points in the configuration process: Privileged Exec, Interface Configuration, and Profile Configuration modes. You can use the pppoe url command at two different points in the configuration process: Interface Configuration and Profile Configuration modes. Note the differences described in guidelines below.

pppoe motm

Use to cause the PPPoE application to send a PADM message of the minute (MOTM) message to all PPPoE clients connected to the router. The MOTM string is passed with no changes.
The message string is not saved in nonvolatile storage (NVS).
Use in Privileged Exec mode.
Example
host1#pppoe motm Router going down at 10:00 p.m.
Use the no version to disable the message.
See pppoe motm.

pppoe motm

Use in the context of a PPPoE subinterface to cause the PPPoE application to send the specified PADM message to the client as it is configured (if connected).
The message is also sent whenever the subinterface transitions from down to up.
The message string is saved in nonvolatile storage (NVS).
Use in Interface Configuration mode.
Example
host1(config-if)#interface fastEthernet 1/0.1.1 host1(config-if)#pppoe motm Router going down at 10:00 p.m.
Use the no version to disable the message.
See pppoe motm.

pppoe motm

Use in a profile to cause the PPPoE application to send the string to the new client that is created when the profile is dynamically attached to an IP interface.
The message string is saved in nonvolatile storage (NVS).
Use in Profile Configuration mode.
Example
host1(config-profile)#pppoe motm Router going down now
Use the no version to disable the message.
See pppoe motm.

pppoe url

Use in the context of a PPPoE subinterface to cause the PPPoE application to send the specified PADM message to the client as it is configured (if connected).
The message is also sent whenever the subinterface transitions from down to up.
The message string is saved in nonvolatile storage (NVS).
Use in Interface Configuration mode.
Example
host1(config-if)#interface fastEthernet 1/0.1.1 host1(config-if)#pppoe url http://www.relevanturl.com
Use the no version to disable the message.
See pppoe url.

pppoe url

Use in a profile to cause the PPPoE application to send the string to the new client that is created when the profile is dynamically attached to an IP interface.
The message string is saved in nonvolatile storage (NVS).
PPPoE substitutes the following characters for information in the specified URL string before transmitting:
- %U user and domain name
- %u user name
- %d domain name
- %D profile name
- %% % character
Use in Profile Configuration mode.
Example
host1(config-profile)#pppoe url http://www.relevanturl.com
Use the no version to disable the message.
See pppoe url.
