A comprehensive tour of the available network management technologies available for todays networks. After defining network management the course moves onto basic tools such as nmap that can be used to manage networks. SNMP is then covered in detail followed by the *flow technologies and streaming telemetry. SDN is then covered with course culminating with network automation and configuring networks with ansible. Hands on sessions are used to reinforce the theory rather than teach specific manufacturer equipment.

"Good content, good lecture, good venue."
"Course instructor knew the subject very well and answered all technical questions in an easy to understand manner. Excellent instructor! "
This structured course uses Instructor Led Training to provide the best possible learning experience. Small class sizes ensure students benefit from our engaging and interactive style of teaching with delegates encouraged to ask questions throughout the course. Quizzes follow each major section allowing checking of learning. Hands on sessions are used throughout to allow delegates to consolidate their new skills.
