This parameter must be set. Defaults to if not set. If not given, defaults to This doesn't need to be set unless readers are connecting to a non-standard port. If your secret includes spaces, tabs, or " ", be sure to include it in double quotes. Can be used to prepend something like "news-" to all usernames in order to put news users into a different namespace from other accounts served by the same server. To receive nonencrypted tunnel passwords in attribute 69 Tunnel-Password , use the radius-server attribute 69 clear global configuration command.
To disable this feature and receive encrypted tunnel passwords, use the no form of this command. Because nonencrypted tunnel passwords can be sent in attribute 69, the NAS will no longer decrypt tunnel passwords.
Note Once this command is enabled, all tunnel passwords received will be nonencrypted until the command is manually disabled. The following example shows how to enable attribute 69 to receive nonencrypted tunnel passwords. To see whether the Tunnel-Password process is successful, use the debug radius command. To send the number of remaining links in the multilink bundle in the accounting-request packet, use the radius-server attribute format non-standard global configuration command.
To disable the sending of the number of links in the multilink bundle in the accounting-request packet, use the no form of this command. Use this command to send attribute in accounting "start" and "stop" records. The radius-server attribute nas-port extended command is replaced by the radius-server attribute nas-port format command. See the description of the radius-server attribute nas-port format command in this chapter for more information.
This is the default format used by Cisco IOS software. The upper 16 bits of the NAS-Port attribute display the type and number of the controlling interface; the lower 16 bits indicate the interface that is undergoing authentication. Note This command replaces the radius-server attribute nas-port extended command. To prevent user responses to Access-Challenge packets from being displayed on the screen, use the radius-server challenge-noecho global configuration command.
To return to the default condition, use the no form of this command. This command applies to all users. When the radius-server challenge-noecho command is configured, user responses to Access-Challenge packets are not displayed unless the Prompt attribute in the user profile is set to echo on the RADIUS server. The Prompt attribute in a user profile overrides the radius-server challenge-noecho command for the individual user. To have the Cisco router or access server query the vendor-proprietary RADIUS server for the static routes and IP pool definitions used throughout its domain when the device starts up, use the radius-server configure-nas command in global configuration mode.
Use the radius-server configure-nas command to have the Cisco router query the vendor-proprietary RADIUS server for static routes and IP pool definitions when the router first starts up.
Note Because the radius-server configure-nas command is performed when the Cisco router starts up, it will not take effect until you issue a copy system:running-config nvram:startup-config command. The following example shows how to tell the Cisco router or access server to query the vendor-proprietary RADIUS server for already-defined static routes and IP pool definitions when the device first starts up:.
To improve RADIUS response times when some servers might be unavailable, use the radius-server deadtime command in global configuration mode to cause the unavailable servers to be skipped immediately. To set dead-time to 0, use the no form of this command. 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 or unless there are no servers not marked "dead. The following example specifies five minutes deadtime for RADIUS servers that fail to respond to authentication requests:.
To disable the directed-request feature, use the no form of this command. Optional Prevents the user from being sent to a secondary server if the specified server is not available. The radius-server directed-request command sends only the portion of the username before the " " symbol to the host specified after the " " symbol.
In other words, with this command enabled, you can direct a request to any of the configured servers, and only the username is sent to the specified server. Disabling the radius-server directed-request command causes the whole string, both before and after the " " symbol, to be sent to the default RADIUS server. The router queries the list of servers, starting with the first one in the list. It sends the whole string, and accepts the first response that it gets from the server.
Use the radius-server directed-request restricted command to limit the user to the RADIUS server identified as part of the username. The no radius-server directed-request command causes the entire username string to be passed to the default RADIUS server. Note When no radius-server directed-request restricted is entered, only the "restricted" flag is removed, and the "directed-request" flag is retained.
To disable the directed-request feature, you must also issue the no radius-server directed-request command. The radius-server extended-portnames command is replaced by the radius-server attribute nas-port format command.
Optional Port number for authentication requests; the host is not used for authentication if set to 0. If unspecified, the port number defaults to Optional Port number for accounting requests; the host is not used for accounting if set to 0.
This setting overrides the global value of the radius-server timeout command. If no timeout value is specified, the global value is used. Enter a value in the range 1 to Optional Specifies the timeout value.
This setting overrides the global setting of the radius-server retransmit command. Optional Specifies the retransmit value. If no retransmit value is specified, the global value is used. This key overrides the global setting of the radius-server key command. If no key string is specified, the global value is used.
Always configure the key as the last item in the radius-server host command syntax. This is because the leading spaces are ignored, but spaces within and at the end of the key are used.
If you use spaces in the key, do not enclose the key in quotation marks unless the quotation marks themselves are part of the key. All 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 themselves are part of the key.
You can use multiple radius-server host commands to specify multiple hosts. The software searches for hosts in the order in which you specify them. If no host-specific timeout, retransmit, or key values are specified, the global values apply to each host. The following example specifies host1 as the RADIUS server and uses default ports for both accounting and authentication:. The following example specifies port as the destination port for authentication requests and port as the destination port for accounting requests on the RADIUS host named host Because entering a line resets all the port numbers, you must specify a host and configure accounting and authentication ports on a single line.
When asking questions, include the output from debugging mode radiusd -X. This information will allow people to help you. Without it, your message will get ignored. When a user connects to the access server, s he is asked for a login- name and a password. This information is then sent to the radius server. The server replies with "access denied", or "access OK". In the latter case login information is sent along, such as the IP address in the case of a PPP connection.
The access server also sends login and logout records to the radius server so accounting can be done. Each file has it's own manpage describing the format of the file. Click here to get plain text attribute list of MikroTik specific attributes FreeRadius comaptible.
Note: FreeRadius already has these attributes predefined. If you are using other radius server then use table below to create dictionary file. From MikroTik Wiki. Categories : Manual AAA.
