LX Series Configuration Guide
Configuring an IP Interface for PPP
You can bind an IP interface to PPP and specify a dedicated
asynchronous port for the IP interface to use for PPP Links.
In addition, you can configure CHAP or PAP authentication, CCP
negotiation, IPCP and LCP parameters, the PPP Mode, and the
Remote IP address for PPP Links on an IP interface.
The LX unit also supports PPP routing via static routing. With
PPP routing, you can manage serially connected devices on
remote LX units that do not have Ethernet connectivity. For
more information on the LX implementation of PPP Routing, see
“PPP Routing on the LX” on page 16-9.
X To configure PPP on an IP interface
1. Use the interface command in Configuration
Command Mode:
Example Config:0 >>interface 2
This enters the Interface Command Mode for the specified
interface (for example, Interface 2). The Interface Command
prompt (such as Intf 2-2:0 >>) is displayed.
2. Execute the bind port async protocol ppp command to
bind the IP interface to PPP, and to specify the
asynchronous port that the IP interface will use for its
PPP Links. In the following example, IP interface 2 is bound
to PPP, and asynchronous port 4 is specified as the port
that IP interface 2 will use for its PPP Links:
Example Intf 2-2:0 >>bind port async 4 protocol ppp
3. Execute the ppp command to access the PPP Command
Mode for the IP interface:
Example Intf 2-2:0 >>ppp
4. Execute the authentication command to specify CHAP or
PAP as the authentication method for PPP Links on the IP
interface. In the following example, CHAP is specified as
the authentication method:
