Configuring Ppp Callback - 3Com 3C13636 Configuration Manual

3Com Router 3000 Ethernet Family
Configuration Guide
When the three commands, ppp mp min-bind, dialer threshold, and ppp mp
max-bind, are configured, the router performs MP bundling as follows:
1) Bring up a minimum number of links depending on the setting of the ppp mp
min-bind command.
2) If traffic size exceeds the link load threshold set by the dialer threshold command
still, bring up the next idle link. This process continues until the number of links
reaches the upper limit set by the ppp mp max-bind command or traffic size
decreases below the specified link load threshold.

1.2.5 Configuring PPP Callback

When configuring PPP callback, one endpoint of a connection should be configured as
client, and the other endpoint as server. The calling party is the callback client and the
called party is the callback server. The client first originates a call, and the server
determines whether to originate a return call. If it determines to do that, the callback
server disconnects and then originates a return call according to the information such
as user name or callback number.
Note:
Configure PPP callback after completing the basic configuration of C-DCC or
RS-DCC.
PPP callback implementation requires authentication. The users are recommended
to configure PAP or CHAP authentication on both the physical and dialer interfaces
on both the callback client and server.
I. Configuring PPP callback in the C-DCC implementation
1) Configure PPP callback client in the C-DCC implementation
As a callback client, a router can originate calls to the remote end (which can be a
router or Windows NT server having the PPP callback server function), and receive the
return calls from the remote end.
Use local-user in system view and password in local user view to configure a
username and password, and perform other configurations in dial interface (physical or
dialer interface) view.
