Chapter 12 Network Management Tools and Systems 12.1 Network Management Tools The catalog of network management tools is extensive,and we cannot do justice to the full range of these tools here.They are necessary for troubleshooting of problems in networks and supplement system tools that detect problems or failures and notify the various alarms.In this section,we will consider the tools used daily by network managers and operators to conduct their activities.Some of these tools can also be utilized by network users in their normal use of network services
