Check RADIUS Server Connectivity - Baseline Operations Guide

It is important to check connectivity to the RADIUS server when attempting to diagnose an authentication problem.

In configuration mode, go to the following hierarchy level:


                  
                     [edit]
                     user@host# edit system

Determine the IP address of the RADIUS server:


                  
                     [edit system]
                     user@host# show

For example:


                  
                     [edit system]
                     user@host# show            
                         
                     
                     host-name nut;
                     domain-name englab.company.net;
                     [...Output truncated...]
                     radius-server {     
                     
                        
                               10.10.10.5 {
                                   secret "$9$14bhlM-VYJGDX7-w2gUD"; # SECRET-DATA
                                   timeout 5;
                                   retry 3;
                           }
                        
                     
                     
                        
                               10.10.10.240 {
                                   secret "$9$hMKrMXwYoDik-VwgaJHk"; # SECRET-DATA
                                   timeout 5;
                                   retry 3;
                           }
                        
                     
                     }
                     [...Output truncated...]

Ping the IP address of the RADIUS server:


                  
                     user@host# run ping IP address

For example:


                  
                     user@host# run ping 10.10.10.5     
                     PING 10.10.10.5 (10.10.10.5): 56 data bytes
                     64 bytes from 10.10.10.5: icmp_seq=0 ttl=254 time=0.402
                        ms
                     
                     64 bytes from 10.10.10.5: icmp_seq=1 ttl=254 time=0.279
                        ms
                     
                     64 bytes from 10.10.10.5: icmp_seq=2 ttl=254 time=0.292
                        ms
                     
                     64 bytes from 10.10.10.5: icmp_seq=3 ttl=254 time=0.283
                        ms
                     
                     64 bytes from 10.10.10.5: icmp_seq=4 ttl=254 time=0.283
                        ms
                     
                     ^C

The sample output shows that the RADIUS server is connected and that the connection is running at a reasonable speed.
