Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010, Руководство по настройке

Страница: 574 / 774

In this example, the router first attempts EAP negotiation. If PPP receives a NAK
from the peer in response to the EAP request, then the router attempts CHAP
negotiation. If PPP receives a NAK from the peer in response to the CHAP request,
then the router attempts PAP negotiation. If PAP is also rejected, then PPP
terminates the session.
■
Use the no version to specify that the router does not require authentication.
■
See ppp authentication.
pppoe
■
Use to specify PPPoE as the encapsulation method for the interface.
■
This command creates a PPPoE major interface.
■
Example
host1(config-if)# pppoe
■
Use the no version to remove the PPPoE major interface.
■
See pppoe.
profile
■
Use from Global Configuration mode to create a profile. You can specify a profile
name of up to 80 characters.
■
Use from Interface Configuration mode or Subinterface Configuration mode to
assign a profile to a PPP interface. The profile configuration is used to dynamically
create an upper IP interface.
■
Example 1–Creates a profile named foo.
host1(config)# profile foo
■
Example 2–Assigns a profile named action to a PPP interface.
host1(config-if)# interface gigabitEthernet 2/1
host1(config-if)# encapsulation ppp
host1(config-if)# profile action
■
Use the no version from Global Configuration mode to remove a profile.
■
Use the no version from Interface Configuration mode or Subinterface
Configuration mode to remove a profile assignment from an interface.
