Chapter 5. Router Access and System Administration


There are two categories of methods for accessing any router. A physical connection can be made from relatively close proximity or a connection can be made from a remote location. A physical close-proximity connection is by default the only way of connecting to the router. Once a physical connection has been made and the appropriate configuration statements put into place, connections can be established from remote locations as needed. With the convenience of remote access comes security risk; therefore, measures must be taken to prevent unauthorized access to the device. These measures include enabling services that will allow authorized users to access the system and defining permissions and restrictions for the users based on their individual job responsibilities. These activities are a major part of the administrative duties of a network engineer.

This chapter describes the craft interfaces on the Juniper Networks M-Series routers and how to configure the settings for the console port, auxiliary port, and the management Ethernet connections. It also outlines the broad range of administrative activities a network engineer would perform during a typical router installation. This chapter concludes with a case study, which coherently demonstrates the configuration components described throughout this portion of the book.
