External servers are often used to store security backups of network devices like Cisco or Juniper switches and routers. This backups include operation system images like Cisco IOS and Juniper JUNOS, and more often configuration files from devices.
When we want to configure some of the networking devices, we usually connect to the device with laptop, directly with console cable. This is the best way to set up the device for the first time, and it may be the only way. It’s because, first thing’s first, we need to setup the device to make it possible for us to communicate with other devices on the network. And then, when the router or the switch are ready to communicate, the best way to make all future changes is by doing it from a certain remote centralized location,by simply connecting to the devices using Telnet or SSH. This is because we don’t need to be literally in front of the device to configurate it; we can be on the other side of the network and remotely connect.
In this article we will help you understand Cisco IOS and Juniper JUNOS command line configurational modes that are first thing that you must know if you want to get into Cisco or Juniper device configuration. This modes will enable you to access different levels of configuration. In this manner you will be allowed to set the device up and running.
This article will help you understand and manage basic configuration of devices from different brands. With Cisco and Juniper router configurations, you will be able to manage network that is made of devices from other sellers, not only Cisco. In that way, you will not be in problems when making some implementation, changes or troubleshooting connectivity issues on multi-brand network topologies.
