Changes in Behavior and Syntax

This section lists the changes in behavior of Junos OS features and changes in the syntax of Junos OS statements and commands from Junos OS Release 15.1F3 for the MX Series and T Series.

Subscriber Management and Services (MX Series)

Note: Although present in the code, the subscriber management features are not supported in Junos OS Release 15.1F3. Documentation for subscriber management features is included in the Junos OS Release 15.1 documentation set.

  • Local DNS configurations available when authentication order is set to none (MX Series)—Starting in Junos OS Release 15.1F2, subscribers get the DNS server addresses when both of the following are true:
    • The authentication order is set to none at the [edit access profile profile-name authentication-order] hierarchy level.
    • A DNS server address is configured locally in the access profile with the domain-name-server, domain-name-server-inet, or domain-name-server-inet6 statement at the [edit access profile profile-name] hierarchy level.

    In earlier releases, subscribers get an IP address in this situation, but not the DNS server addresses.


  • Clear all Internet key exchange (IKE), traffic encryption key (TEK), key encryption key (KEK), and security associations (SAs) for group VPN (MX Series)—The clear security group-vpn member group CLI command has been introduced in the Release 15.1F3 of Junos OS for MX Series routers to clear all Internet key exchange (IKE), traffic encryption key (TEK), key encryption, and key (KEK) security associations (SAs) for a group VPN.
