To configure a default CHAP secret for an interface, include the default-chap-secret statement at the [edit interfaces interface-name ppp-options chap] hierarchy level:
- [edit interfaces interface-name ppp-options chap]
-
default-chap-secret name;
The default CHAP secret is used when no matching CHAP access profile exists, or if the CHAP name changes during PPP link negotiation.
