Junos Subscriber Management (JSM)

Junos Subscriber Management (JSM) 

This four-day course is designed to provide students with the knowledge required to configure and manage subscriber management on devices running the Junos operating system. This course focuses on the main configuration components of subscriber management, including subscriber authentication, authorization, and accounting (AAA), Dynamic Host Configuration Protocol (DHCP) local server and DHCP relay/proxy agent, the Point-to-Point Protocol (PPP), subscriber addressing, dynamic profiles, subscriber interfaces, Layer 3 and Layer 2 wholesale services, Pseudowire Head-end Termination (PHT), L2TP, dynamic firewall services, subscriber class of service (CoS), dynamic multicast services, basic NAT and CGN functions, and Subscriber Secure Policy (SSP, or Lawful Intercept). Through demonstrations and hands-on labs, students will gain experience in configuring, monitoring, and troubleshooting subscriber management features on MX Series Universal Edge Routers running the Junos OS.

Additional Details

This course is based on the Junos OS Release 20.1R1.11.
