Junos OS Configuration from External Devices

 

You can configure the router from a system console connected to the router’s console port or by using Telnet to access the router remotely. The router provides three ports on the craft interface for connecting external management devices to the Routing Engine and the Junos OS:

  • Console port—Connects a system console using an RS-232 serial cable.

  • Auxiliary port—Connects a laptop or modem using an RS-232 serial cable.

  • Ethernet management port—Connects the Routing Engine to a management LAN (or any other device that plugs into an Ethernet connection) for remote management through a PC or other client device. The Ethernet port is 10/100 megabits per second (Mbps) autosensing and requires an RJ-45 connector.
