Beskrivning
This five-day course provides a comprehensive focus on Juniper Networks data center switching technologies.
The first two days are designed to introduce the data center features including zero touch provisioning (ZTP), unified in-service software upgrade (ISSU), multichassis link aggregation (MC-LAG), Mixed Virtual Fabric, and Virtual Chassis Fabric (VCF).
The third day of the course is designed to provide students with advanced knowledge of troubleshooting key data center features including MC-LAG, Virtual Chassis, and VCF deployments.
The last two days of the course are designed to introduce data center features that are more advanced including IP Fabric, Virtual eXtensible Local Area Network (VXLAN) Layer 2 and Layer 3 Gateways, VXLAN with Ethernet VPN (EVPN) signaling, and Data Center Interconnect (DCI) for a VXLAN overlay. Students will learn to configure and monitor these features on the Junos operating system running on the QFX5100, EX4300, and vMX Series platforms.
Through demonstrations and hands-on labs, students will gain experience configuring, monitoring, troubleshooting, and analyzing the mentioned features of the Junos OS. This content is based on Junos OS Release 13.2X51-D21.1 and 14.1X53.
Advanced Data Center Switching (ADCX) begins at an intermediate-level course, and finishes at an advanced level.
