Configuring Pppoe - Avaya G250 Administration

Configuring PPPoE

1. Enter the context of the Fast Ethernet interface, using the command interface
FastEthernet 10/2.
2. Use the encapsulation pppoe command to change the encapsulation to PPPoE. You
must change the encapsulation to PPPoE before configuring an IP address on the
interface.
Note:
You cannot use PPPoE if:
Note:
- An IP address must not be configured on the interface.
- Dynamic CAC is not enabled on the interface. See
- The interface is not part of a primary-backup interface pair. See
interfaces
3. Use the ip address command to configure an IP address and subnet mask for the
interface. In most cases, PPPoE tunnels require a 32-bit subnet mask.
Alternatively, you can use the ip address negotiated command to obtain an IP
address via PPP/IPCP negotiation.
Note:
You cannot configure PPP/IPCP address negotiation if DHCP address
Note:
negotiation is already configured on the interface (see
client
4. Configure an authentication method and parameters:
- For PAP authenticating, type the ppp pap-sent command, followed by a username
and password. For example:
G350-001(super-if:FastEthernet 10/2)# ppp pap-sent username avaya32 password 123456
Done!
- For CHAP authentication, use the ppp chap hostname command, followed by a
hostname, and the ppp chap password command, followed by a password. For
example:
G350-001(super-if:FastEthernet 10/2)# ppp chap hostname avaya32
Done!
G350-001(super-if:FastEthernet 10/2)# ppp chap password 123456
Done!
Note:
Authentication parameters do not appear in the startup or running configuration
Note:
files. You can use the show ppp authentication command to view
authentication status. The copy running-config startup-config
command stores authentication parameters in NVRAM.
