Add a RADIUS Server

About this task

Add a RADIUS server to provide RADIUS service on the switch.

RADIUS supports IPv4 and IPv6 addresses, with no difference in functionality or configuration using CLI.

Procedure

Enter Global Configuration mode:

enable

configure terminal
Add a RADIUS server:

radius server host WORD <0–46> key WORD<0-32> [used-by {cli|eapol|endpoint-tracking|snmp|web}] [acct-enable][acct-port <1-65536>] [enable] [port <1-65536>][priority <1-10>][retry <0-6>] [secure-enable] [secure-log-level] [secure-mode] [secure-profile] [timeout <1-60>]

Example

Add a RADIUS server:

Switch:1>enable
Switch:1#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Switch:1(config)#radius server host 4717:0000:0000:0000:0000:0000:7933:0001 key testkey1 used-by snmp port 12 retry 5 timeout 10 enable

Variable Definitions

The following table defines parameters for the radius server host command.


Variable	Value
used-by {cli\|eapol\|endpoint-tracking\|snmp\|web}	Configures how the server functions: cli—configure the server for CLI authentication. eapol—configure the server for EAPoL authentication. endpoint-tracking—configure the server for Endpoint Tracking authentication. snmp—configure the server for SNMP accounting. web—configure the server for HTTP(s) authentication. Use the no option to remove a host server: no radius server host WORD<0–46> used-by {cli\|eapol\|endpoint-tracking\|snmp\|web}. The default is cli. The default command is: default radius server host WORD<0–46> used-by {cli\|eapol\|endpoint-tracking\|snmp\|web}.
host `WORD <0–46>`	Configures a host server. WORD <0–46> signifies an IPv4 address in the format A.B.C.D or an IPv6 address in the format x:x:x:x:x:x:x:x. RADIUS supports IPv4 and IPv6 addresses, with no difference in functionality or configuration using CLI.
acct-enable	Enables RADIUS accounting on this server. The system enables RADIUS accounting by default.
acct-port `<1-65536>`	Configures the UDP port of the RADIUS accounting server (1 to 65536). The default value is 1813. Important: The UDP port value set for the client must match the UDP value set for the RADIUS server.
enable	Enables the RADIUS server. The default is true.
key `WORD<0–32>`	Configures the secret key of the authentication client.
port `<1-65536>`	Configures the UDP port of the RADIUS authentication server. The default value is 1812.
priority `<1–10>`	Configures the priority value for this server. The default is 10.
retry `<0–6>`	Configures the number of authentication retries the server will accept. The default is 3.
secure-enable	Enable RADIUS Security (RADSec).
secure-log-level	Specifies the log severity level. Possible values are : critical debug error info warning
secure-mode	Specifies the protocol used for secure connection to the server.
secure-profile	Configures the secure profile for the server.
timeout `<1–180>`	Configures the number of seconds before the authentication request times out. The default is 8.
