3Com WX3000 Configuring the Type of Radius Servers to be Supported, Key authentication string

received from each other by using the shared keys that have been set on them, and can accept and respond to the messages only when both parties have the same shared key.

Follow these steps to configure shared keys for RADIUS messages:

To do…	Use the command…	Remarks
Enter system view	system-view	—
		Required
Create a RADIUS scheme and	radius scheme	By default, a RADIUS scheme
enter its view	radius-scheme-name	named "system" has already
		been created in the system.
Set a shared key for RADIUS		Required
authentication/authorization	key authentication string	By default, no shared key is
messages		created.
Set a shared key for RADIUS		Required
	key accounting string	By default, no shared key is
accounting messages
		created.

The authentication/authorization shared key and the accounting shared key you set on the device must be respectively consistent with the shared key on the authentication/authorization server and the shared key on the accounting server.

Configuring the Maximum Number of RADIUS Request Transmission Attempts

The communication in RADIUS is unreliable because this protocol uses UDP packets to carry its data. Therefore, it is necessary for the device to retransmit a RADIUS request if it gets no response from the RADIUS server after the response timeout timer expires. If the device gets no answer after it has tried the maximum number of times to transmit the request, the device considers that the request fails.

Follow these steps to configure the maximum transmission attempts of a RADIUS request:

To do…	Use the command…	Remarks
Enter system view	system-view	—
		Required
Create a RADIUS scheme and	radius scheme	By default, a RADIUS scheme
enter its view	radius-scheme-name	named "system" has already been
		created in the system.
Set the maximum number of		Optional
RADIUS request transmission	retry retry-times	By default, the system can try three
attempts		times to transmit a RADIUS request.
