Cisco Systems OL-6415-04 Selecting the Csid Format, Configuring Settings for All Radius Servers

Chapter 7 Configuring RADIUS Servers

Configuring and Enabling RADIUS

Selecting the CSID Format

You can select the format for MAC addresses in Called-Station-ID (CSID) and Calling-Station-ID attributes in RADIUS packets. Use the dot11 aaa csid global configuration command to select the CSID format. Table 7-1lists the format options with corresponding MAC address examples.

	Table 7-1	CSID Format Options
	Option		MAC Address Example
	default		0007.85b3.5f4a
	ietf		00-07-85-b3-5f-4a
	unformatted		000785b35f4a
	To return to the default CSID format, use the no form of the dot11 aaa csid command, or enter
	dot11 aaa csid default.
Note	You can also use the aaa csid command to select the CSID format.

Configuring Settings for All RADIUS Servers

Beginning in privileged EXEC mode, follow these steps to configure global communication settings between the access point and all RADIUS servers:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	radius-server key string	Specify the shared secret text string used between the access point and all
		RADIUS servers.
		Note The key is a text string that must match the encryption key used on
		the RADIUS server. Leading spaces are ignored, but spaces within
		and at the end of the key are used. If you use spaces in your key, do
		not enclose the key in quotation marks unless the quotation marks
		are part of the key.
Step 3
	radius-server retransmit retries	Specify the number of times the access point sends each RADIUS request
		to the server before giving up. The default is 3; the range 1 to 1000.
Step 4
	radius-server timeout seconds	Specify the number of seconds an access point waits for a reply to a
		RADIUS request before resending the request. The default is 5 seconds; the
		range is 1 to 1000.
Step 5
	radius-server deadtime minutes	Use this command to cause the Cisco IOS software to mark as “dead” any
		RADIUS servers that fail to respond to authentication requests, thus
		avoiding the wait for the request to time out before trying the next
		configured server. A RADIUS server marked as dead is skipped by
		additional requests for the duration of minutes that you specify, up to a
		maximum of 1440 (24 hours).
		Note If you set up more than one RADIUS server, you must configure the
		RADIUS server deadtime for optimal performance.
