This section describes the new features or enhancements to existing features in Contrail Service Orchestration (CSO) Release 4.0.2. For new and changed features in CSO Release 4.0.0, see the CSO 4.0.0 Release Notes at https://www.juniper.net/documentation/en_US/cso4.0/ information-products/ pathway-pages/4.0/index.html.
CHAP authentication support for PPPoE—From Release 4.0.2 onward, Contrail Service Orchestration enables you to choose CHAP authentication for PPPoE. You can now choose either PAP or CHAP as the authentication protocol for PPPoE when you configure a site. PPPoE is available only on ADSL and VDSL links and in previous releases supported only PAP authentication.
ZTP of NFX250 over ADSL and VDSL links—From Release 4.0.2 onward, Contrail Service Orchestration supports ZTP of NFX250 devices with static and DHCP-based addressing over ADSL and VDSL links. The staging script (dsl-pre-staging.tgz) performs the configuration based on input YAML and configures JDM, JCP, and GWR for provisioning ADSL and VDSL links. After this, ZTP can be done over the link.
Note In CSO Release 4.0.2, ZTP is not supported with PPPoE over ADSL and VDSL links.
MX Series routers as cloud hub—From Release 4.0.2, Contrail Service Orchestration supports MX Series routers as cloud hub devices.
Ability to specify the supported platform while uploading a device image—From Release 4.0.2, Contrail Service Orchestration enables you to specify the supported device when you upload a device image. This field is not mandatory. However, information provided in this field is useful in identifying the right image while upgrading physical SRX family devices during the Site Upgrade workflow.
