Radius Server Setup

September 10, 2023 - Reading time: 3 minutes

In a Cisco environment, a RADIUS (Remote Authentication Dial-In User Service) server is commonly used to authenticate users for various network services, one of which is network access. This lab introduces using a RADIUS server to allows for centralized user authentication. Instead of maintaining separate user accounts and authentication databases on each network device. All authentication requests are sent to the RADIUS server. This centralization simplifies administration and ensures consistent authentication across the network.

With local authentication, administrators can define user accounts and passwords locally on a network device, rather than relying on external authentication servers.

Switch Errdisable Recovery

February 27, 2021 - Reading time: 4 minutes

In this tutorial we look at errdisable recovery and highlight it on the PocketCLI Network Simulator. Errdisable recovery is a feature on Cisco switches that allows network administrators to automatically activate an err-disabled port after a specified timeout period. 

A common cause for an interface to be placed in err-disable status is a port security violation. Please reference the tutorial Port Security - Configuration for more details. The port in the err-disabled state needs an administrator to manually restore the port back to operation. Activation of the port will be accomplished by issuing the command shutdown followed by the no shutdown command.

The topology below will be used for this tutorial:
