Configuring Ppp - Avaya G250 Administration

Configuring PPP

PPP is the default encapsulation on a WAN port. If the encapsulation has been changed to
frame relay and you want to restore PPP encapsulation, or to change the PPP parameters:
1. Ensure that you are in the context of a serial interface that is defined on the port. If you are
not in the context of a serial interface, use the interface Serial command. To view
all serial interfaces that are defined, use the show interfaces Serial command.
2. If the interface is not already configured to use PPP encapsulation, use the
encapsulation ppp command to change the encapsulation to PPP.
3. If you want to change the queuing mode of the interface, see
(WFVQ)
4. Use the following commands to change the interface parameters:
- Use the ip address command to configure the IP address and subnet mask of the
interface.
- Use the ppp timeout ncp command to set the maximum time to wait for the
network layer to negotiate. If this time is exceeded, the G250/G350 restarts the PPP
session.
- Use the ppp timeout retry command to set the maximum time to wait for a
response during PPP negotiation.
- Use the keepalive-icmp command to enable keepalive or change the interval to
which keepalive is set. When activated, keepalive performs the initial negotiation and
sends health checks at defined intervals to the other side of the interface. To
deactivate keepalive, use the no form of the command or set the health check interval
to 0.
5. Type exit to return to general context. The prompt returns to:
G350-001(super)#
6. Test the WAN configuration. See
connectivity
7. Use the copy running-config startup-config command to save the
configuration.
