Internetworking Routers and Switches (IRS)

Understand interoperability issues when running in a multivendor network.

Course Description

Today's corporations base their success on the performance of their voice and data communications networks. In order to design and configure these rapidly evolving networks, an understanding of routing and switching technologies is essential. In this powerful 3-day course, extensive hands-on labs, utilizing Cisco, Dell, 3Com, and Nortel routers and switches, will help you understand routing and switching concepts, as well as how to better design and configure your real-world internetworks.

Course Objectives

MARS solution, features, and functions as they relate to security incidents and security information in an enterprise network
Basic physical installation process
Add Cisco security and network devices into MARS appliance
Add Non-Cisco security and network devices into MARS appliance
Configure security devices to generate interesting events that constitute an attack scenario and have MARS collect the events for incident investigation
Attack mitigation and false positive confirmation in context of MARS appliance
Configure appliance to perform Incident Investigation and Mitigation
Explain how to create, view, and save a long-duration query and reports on the MARS appliance
Configure the MARS appliance to send an alert
Describe and configure rules that detect interesting patterns of network activity
Use management features in the MARS appliance to assign event, addressing, service, and user information
Configure hardware maintenance chores such as viewing audit trail, data archiving, hot swapping hard drives, and upgrading software on MARS appliance.
Overview of MARS Global Controller
Overview of Log Parser Templates

Intended Audience

Networking professionals who need a working knowledge of routing and switching within a multivendor network. Administrators, IT managers, marketing/sales personnel who need to understand routing and switching, network designers, network engineers, sales engineers, technicians, telecom managers, and engineers working in a Cisco, Dell, 3Com, and Nortel networking environment.

Prerequisites

This course assumes a basic understanding of networking knowledge. Understanding Networking Fundamentals is an excellent prerequisite course.
