To display information associated with RADIUS, use the debug radius command in privileged EXEC 
mode. To disable debugging output, use the no form of this command. 

debug radius [accounting | authentication | brief | elog | failover | retransmit | verbose ]

no debug radius [accounting | authentication | brief | elog | failover | retransmit | verbose ]

Debugging output in ASCII format is enabled. 

Privileged EXEC 

RADIUS is a distributed security system that secures networks against unauthorized access. Cisco 
supports RADIUS under the authentication, authorization, and accounting (AAA) security system. 
When RADIUS is used on the router, you can use the debug radius command to display detailed 
debugging and troubleshooting information in ASCII format. Use the debug radius brief command for 
abbreviated output displaying client/server interaction and minimum packet information. Use the debug 
radius hex command to display packet dump information that has not been truncated in hex format. 

The following is sample output from the debug radius command: 

Router# debug radius 

Radius protocol debugging is on 

Radius packet hex dump debugging is off 

Router# 

00:02:50: RADIUS: ustruct sharecount=3 

00:02:50: Radius: radius_port_info() success=0 radius_nas_port=1 

(Optional) RADIUS accounting packets only

(Optional) RADIUS authentication packets only

(Optional) Displays abbreviated debug output. brief Only I/O transactions 
are recorded.

(Optional) RADIUS event logging. 

(Optional) Packets sent upon fail-over

(Optional) Retransmission of packets

(Optional) Include non essential RADIUS debugs
