3Com Router 3000 Ethernet Family
Configuration Guide
Table 1-17 Implement PPP callback (server configuration) in C-DCC
Set the link layer protocol of the interface
to PPP
Configure an authentication mode
Configure the user name that the local
end will send to the remote end for
CHAP authentication
Configure the password that the local
end will send to the remote end for
CHAP authentication
Configure the callback user and callback
number
Configure the local end to be the PPP
callback server
Disable the local end to be the PPP
callback server
Configure the PPP callback reference
Disable the callback server function of
the router
Configure the destination address(es)
and dial number(s) for calling one (or
more) remote ends
By default, the system does not enable the callback function. Once it is enabled, the
server will originate return calls according to the user name configured in the dialer
route command.
Note:
If the callback client adopts the dynamically assigned network address, the server will
be unable to use the dialer route command to configure a callback dial number to
associate with the network address. In this case, the callback client can only use the
service-type ppp command to configure a callback dial number to associate with the
callback user name, and hence determine the callback reference.
