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).
