NETWORK MANAGEMENT TECHNOLOGIES COURSE DESCRIPTION A comprehensive tour of the available network management technologies available for todays networks. The course starts with basic tools such as syslog along with Python network automation. SNMP is then covered with the *flow technologies and streaming telemetry. Configuration management with ansible, Python, NETCONF and RESTCONF is then studied. The final part of the course looks at SDN. Hands on sessions are used throughout to reinforce the theory rather than teach specific manufacturer equipment. Note that sections are available as individual courses. WHAT WILL YOU LEARN * Evaluate network management technologies. * Evaluate network management technologies. * Recognise the weaknesses of SNMP versus NETCONF and streaming telemetry. * Explain the role of NETCONF and RESTCONF. * Compare & contrast *flow and streaming telemetry. * Explain the role of SDN in network management. * Automate network configuration with ansible and Python. NETWORK MANAGEMENT TECHNOLOGIES COURSE DETAILS * Who will benefit: Those wishing to manage networks.
