Using the BCC
Changing the Authentication Protocol
CHAP is the default authentication protocol. To change the authentication
protocol, navigate to the dial prompt and enter:
authentication-protocol
<
protocol
>
protocol
can be pap, chap, or none.
For example, to switch from the default protocol to PAP, enter:
dial/serial/1/1#
authentication-protocol pap
Modifying CHAP
If you configure CHAP as the authentication protocol, you must configure a
CHAP name and secret.
The CHAP name is part of the outbound call and informs remote peer routers of
the local router’s identity. The CHAP secret is for identification and security, and
must be the same on both sides of the link.
To change the CHAP name and secret, navigate to the ppp circuit prompt and
enter:
chap-name
<
text-string
>
chap-
s
ecret
<
text-string
>
text-string
can be any text string up to 20 characters.
For example, to modify CHAP for the demand circuit to phoenix, enter:
ppp/to-phoenix#
chap-name bayrs1 chap-secret southwest
Note that each circuit must have a unique CHAP name.
Modifying PAP
If you configure PAP as the authentication protocol, you must configure a PAP ID
and PAP password. The PAP ID identifies the calling router to the called router.
During the authentication phase, all password authenticate-request messages that
the calling router sends to the called router must include the correct PAP ID and
password or the connection will not succeed.
