AAA Server Group Configuration Mode Commands

The AAA Server Group Configuration Mode is used to create and manage the Diameter/RADIUS server groups within the context or system. AAA server group facilitates management of group (list) of servers at per subscriber/APN/realm level for AAA functionality.

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

dictionary dictionary

Specifies which dictionary to use. The following table describes the possible values for dictionary:

Dictionary Description

customXX

These are dictionaries that can be customized to fit your needs. Customization information can be attained by contacting your local service representative.

XX is the integer value of the custom dictionary.

standard

This dictionary consists only of the attributes specified in RFC 2865, RFC 2866, and RFC 2869.

3gpp

This dictionary consists not only of all of the attributes in the standard dictionary, but also all of the attributes specified in 3GPP 32.015.

3gpp2

This dictionary consists not only of all of the attributes in the standard dictionary, but also all of the attributes specified in IS-835-A.

3gpp2-835

This dictionary consists not only of all of the attributes in the standard dictionary, but also all of the attributes specified in IS-835.

starent-vsa1

This dictionary consists not only of the 3GPP2 dictionary, but also includes Starent Networks vendor-specific attributes (VSAs) as well. The VSAs in this dictionary support a one-byte wide VSA Type field in order to support certain RADIUS applications. The one-byte limit allows support for only 256 VSAs (0 - 255). This is the default dictionary.

IMPORTANT:

In 12.0 and later releases, no new attributes can be added to the starent-vsa1 dictionary. If there are any new attributes to be added, these can only be added to the starent dictionary. For more information, please contact your Cisco account representative.

starent-vsa1-835

This dictionary consists not only of the 3gpp2-835 dictionary, but also includes Starent Networks vendor-specific attributes (VSAs) as well. The VSAs in this dictionary support a one-byte wide VSA Type field in order to support certain RADIUS applications. The one-byte limit allows support for only 256 VSAs (0 - 255). This is the default dictionary.

starent

This dictionary consists of all of the attributes in the starent-vsa1 dictionary and incorporates additional Starent Networks VSAs by using a two-byte VSA Type field. This dictionary is the master-set of all of the attributes in all of the dictionaries supported by the system.

starent-835

This dictionary consists of all of the attributes in the starent-vsa1-835 dictionary and incorporates additional Starent Networks VSAs by using a two-byte VSA Type field. This dictionary is the master-set of all of the attributes in all of the -835 dictionaries supported by the system.


deadtime minutes

Specifies the number of minutes to wait before changing the state of a RADIUS server from “Down” to “Active”. minutes must be an integer from 0 through 65535.

Default: 10

IMPORTANT:

This parameter should be set to allow enough time to remedy the issue that originally caused the server’s state to be changed to “Down”. After the deadtime timer expires, the system returns the server’s state to “Active” regardless of whether or not the issue has been fixed.

IMPORTANT:

For a complete explanation of RADIUS server states, if you are using StarOS 12.3 or an earlier release, refer to the RADIUS Server State Behavior appendix in the AAA and GTPP Interface Administration and Reference. If you are using StarOS 14.0 or a later release, refer to the AAA Interface Administration and Reference.

detect-dead-server { consecutive-failures consecutive_failures_count | keepalive | response-timeout response_timeout_duration }

consecutive-failures consecutive_failures_count: Specifies the number of consecutive failures, for any AAA Manager, before a server’s state is changed from “Active” to “Down”. consecutive_failures_count must be an integer from 1 through 1000. Default: 4.

keepalive: Enables the AAA server alive-dead detect mechanism based on sending keepalive authentication messages to all authentication servers. Default is disabled.

response-timeout response_timeout_duration: Specifies the number of seconds, for any AAA Manager, to wait for a response to any message before a server’s state is changed from “Active” to “Down”. response_timeout_duration must be an integer from 1 through 65535.

IMPORTANT:

If both consecutive-failures and response-timeout are configured, then both parameters must be met before a server’s state is changed to “Down”.

IMPORTANT:

The “Active” or “Down” state of a RADIUS server as defined by the system, is based on accessibility and connectivity. For example, if the server is functional but the system has placed it into a “Down” state, it could be the result of a connectivity problem. When a RADIUS server’s state is changed to “Down”, a trap is sent to the management station and the deadtime timer is started.

max-outstanding max_messages

Specifies the maximum number of outstanding messages a single AAA Manager instance will queue.

max_messages must be an integer from 1 through 4000.

Default: 256

max-retries max_retries

Specifies the maximum number of times communication with a AAA server will be attempted before it is marked as “Not Responding”, and the detect dead server’s consecutive failures count is incremented.

max_retries must be an integer from 0 through 65535.

Default: 5

max-transmissions max_transmissions

Sets the maximum number of re-transmissions for RADIUS authentication requests. This limit is used in conjunction with max-retries parameter for each server.

When failing to communicate with a RADIUS sever, the subscriber is failed once all of the configured RADIUS servers have been exhausted, or once the configured number of maximum transmissions is reached.

For example, if three servers are configured and if the configured max-retries is 3 and max-transmissions is 12, then the primary server is tried four times (once plus three retries), the secondary server is tried four times, and then a third server is tried four times. If there is a fourth server, it is not tried because the maximum number of transmissions (12) has been reached.

max_transmissions must be an integer from 1 through 65535.

Default: Disabled

probe-message local-service-address ipv4/ipv6_address

radius probe-message: Configures AVPs to be sent in RADIUS authentication probe messages.

local-service-address: Configures the service ip-address to be sent as an AVP in RADIUS authentication probe messages.

ipv4/ipv6_address: Specifies the IP address of the server.

ip_address must be specified in IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal notation. A maximum of 128 RADIUS servers can be configured per context. This limit includes accounting and authentication servers.

strip-domain { authentication-only | accounting-only }

Specifies that the domain must be stripped from the user name prior to authentication or accounting.

By default, strip-domain configuration will be applied to both authentication and accounting messages, if configured.

When the argument authentication-only or accounting-only is present, strip-domain is applied only to the specified RADIUS message types.

timeout idle_seconds

Specifies the number of seconds to wait for a response from the RADIUS server before re-sending the messages.

idle_seconds must be an integer from 1 through 65535.

Default: 3


Usage:

Use this command to configure the basic RADIUS parameters according to the RADIUS server used for the context.


Example:
The following command configures the RADIUS timeout parameter to 300 seconds.
radius timeout 300
radius accounting

This command configures the current context’s RADIUS accounting parameters.

Removes the specified configuration.

default

Configures the default setting for the specified keyword.

archive [ stop-only ]

Enables archiving of RADIUS accounting messages in the system after the accounting message has exhausted retries to all available RADIUS accounting servers. All RADIUS accounting messages generated by a session are serially delivered to the RADIUS accounting server. That is, previous RADIUS accounting messages from the same call must be delivered and acknowledged by the RADIUS accounting server before the next RADIUS accounting message is sent to the RADIUS accounting server.

stop-only specifies archiving of only STOP accounting messages.

Default: enabled

deadtime minutes

Specifies the number of minutes to wait before changing the state of a RADIUS server from “Down” to “Active”.

minutes must be an integer from 0 through 65535.

Default: 10 minutes

IMPORTANT:

This parameter should be set to allow enough time to remedy the issue that originally caused the server’s state to be changed to “Down”. After the deadtime timer expires, the system returns the server’s state to “Active” regardless of whether or not the issue has been fixed.

IMPORTANT:

For a complete explanation of RADIUS server states, if you are using StarOS 12.3 or an earlier release, refer to the RADIUS Server State Behavior appendix in the AAA and GTPP Interface Administration and Reference. If you are using StarOS 14.0 or a later release, refer to the AAA Interface Administration and Reference.

detect-dead-server { consecutive-failures consecutive_failures_count | keepalive | response-timeout response_timeout_duration }

consecutive-failures consecutive_failures_count: Specifies the number of consecutive failures, for any AAA Manager, before a server’s state is changed from “Active” to “Down”. consecutive_failures_count must be an integer from 1 through 1000. Default: 4

keepalive: Enables the AAA server alive-dead detect mechanism based on sending keepalive authentication messages to all authentication servers. Default: disabled

response-timeout response_timeout_duration: Specifies the number of seconds, for any AAA Manager, to wait for a response to any message before a server’s state is changed from “Active” to “Down”. response_timeout_duration must be an integer from 1 through 65535.

IMPORTANT:

If both consecutive-failures and response-timeout are configured, then both parameters must be met before a server’s state is changed to “Down”.

IMPORTANT:

The “Active” or “Down” state of a RADIUS server as defined by the system, is based on accessibility and connectivity. For example, if the server is functional but the system has placed it into a “Down” state, it could be the result of a connectivity problem. When a RADIUS server’s state is changed to “Down”, a trap is sent to the management station and the deadtime timer is started.

IMPORTANT:

If you are using StarOS 14.0 or a later release, refer to the AAA Interface Administration and Reference.

fire-and-forget

Enables RADIUS Fire-and-Forget accounting for the AAA group.

Default: Disabled

The request sent to the RADIUS accounting server configured under the AAA group with this keyword configured will not expect a response from the server. If the request must be sent to more than one such type of server, the acct-algorithm first-n configuration in the AAA group can be used.

Keepalive feature for server state detection is supported in conjunction since there is no waiting for responses. Archiving in such a AAA group is not supported. If the server is down, the request is sent to the next server in the group. If all the servers in the group are down, the request is deleted.

This CLI is independent of the APN or subscriber profile configuration aaa secondary-group aaa_group_name.

interim interval interim_interval

Specifies the time interval, in seconds, for sending accounting INTERIM-UPDATE records.

interim_interval must be an integer from 50 through 40000000.

Default: Disabled

IMPORTANT:

If RADIUS is used as the accounting protocol for the GGSN product, other commands are used to trigger periodic accounting updates. However, these commands would cause RADIUS STOP/START packets to be sent as opposed to INTERIM-UPDATE packets. Also, note that accounting interim interval settings received from a RADIUS server take precedence over those configured on the system.

max-outstanding max_messages

Specifies the maximum number of outstanding messages a single AAA Manager instance will queue.

max_messages must be an integer from 1 through 4000.

Default: 256

max-pdu-size octets

Specifies the maximum sized packet data unit which can be accepted/generated, in bytes (octets).

octets must be an integer from 512 through 2048.

Default: 2048

max-retries max_retries

Specifies the maximum number of times communication with a AAA server will be attempted before it is marked as “Not Responding” and the detect dead server consecutive failures count is incremented.

max_retries must be an integer from 0 through 65535.

Default: 5

Once the maximum number of retries is reached this is considered a single failure for the consecutive failures count for detecting dead servers.

max-transmissions max_transmissions

Sets the maximum number of transmissions for a RADIUS accounting message before the message is declared as failed.

max_transmissions must be an integer from 1 through 65535.

Default: Disabled

timeout timeout_duration

Specifies the duration to wait for a response from a RADIUS server before retransmitting a request.

timeout_duration must be an integer from 1 through 65535.

Default: 3


Usage:

Use this command to configure RADIUS accounting options according to the RADIUS server used for the context.

Configures the default setting.

Default: first-server

first-n n

Default: 1 (Disabled)

Specifies that the AGW must send accounting data to n (more than one) AAA servers based on their priority. The full set of accounting data is sent to each of the n AAA servers. Response from any one of the servers would suffice to proceed with the call. On receiving an ACK from any one of the servers, all retries are stopped.

n is the number of AAA servers to which accounting data will be sent, and must be an integer from 2 through 128.

first-server

Specifies that the context must send accounting data to the RADIUS server with the highest configured priority. In the event that this server becomes unreachable, accounting data is sent to the server with the next-highest configured priority. This is the default algorithm.

round-robin

Specifies that the context must load balance sending accounting data among all of the defined RADIUS servers. Accounting data is sent in a circular queue fashion on a per Session Manager task basis, where data is sent to the next available server and restarts at the beginning of the list of configured servers. The order of the list is based upon the configured relative priority of the servers.


Usage:

Use this command to specify the algorithm to select the RADIUS accounting server(s) to which accounting data must be sent.

minute must be an integer from 0 through 59.

hour must be an integer from 0 through 23.

trigger-event { active-handoff | active-start-param-change | active-stop }

active-start-param-change: Enabled

active-stop: Disabled

Configures the events for which a RADIUS event is generated for accounting as one of the following:
  • active-handoff: Disables a single R-P event (and therefore a RADIUS accounting event) when an Active PCF-to-PFC Handoff occurs. Instead, two R-P events occur (one for the Connection Setup, and the second for the Active-Start)
  • active-start-param-change: Disables an R-P event (and therefore a RADIUS accounting event) when an Active-Start is received from the PCF and there has been a parameter change.
  • active-stop: Disables an R-P event (and therefore a RADIUS accounting event) when an Active-Stop is received from the PCF.

Default: active-handoff: Disabled

IMPORTANT:

This keyword has been obsoleted by the trigger-policy keyword. Note that if this command is used, if the context configuration is displayed, radius accounting rp configuration is represented in terms of the trigger-policy.

trigger-policy { airlink-usage [ counter-rollover ] | custom [ active-handoff | active-start-param-change | active-stop ] | standard }

Default: airlink-usage: Disabled

custom:

active-handoff = Disabled

active-start-param-change = Disabled

active-stop = Disabled

standard: Enabled

Configures the overall accounting policy for R-P sessions as one of the following:
  • airlink-usage [ counter-rollover ]: Specifies the use of Airlink-Usage RADIUS accounting policy for R-P, which generates a start on Active-Starts, and a stop on Active-Stops.
  • If the counter-rollover option is enabled, the system generates a STOP/START pair before input/output data octet counts (or input/output data packet counts) become larger than (2^32 - 1) in value. This setting is used to guarantee that a 32-bit octet count in any STOP message has not wrapped to larger than 2^32 thus ensuring the accuracy of the count. The system, may, at its discretion, send the STOP/START pair at any time, so long as it does so before the 32-bit counter has wrapped. Note that a STOP/START pair is never generated unless the subscriber RP session is in the Active state, since octet/packet counts are not accumulated when in the Dormant state.
  • custom: Specifies the use of custom RADIUS accounting policy for R-P. The custom policy can consist of the following:
  • active-handoff: Enables a single R-P event (and therefore a RADIUS accounting event) when an Active PCF-to-PFC Handoff occurs. Normally two R-P events will occur (one for the Connection Setup, and the second for the Active-Start)
  • active-start-param-change: Enables an R-P event (and therefore a RADIUS accounting event) when an Active-Start is received from the PCF and there has been a parameter change.

    IMPORTANT:

    Note that a custom trigger policy with only active-start-param-change enabled is identical to the standard trigger-policy.

  • active-stop: Enables an R-P event (and therefore a RADIUS accounting event) when an Active-Stop is received from the PCF.

    IMPORTANT:

    If the radius accounting rp trigger-policy custom command is executed without any of the optional keywords, all custom options are disabled.

  • standard: Specifies the use of Standard RADIUS accounting policy for R-P in accordance with IS-835B.
trigger-stop-start

Specifies that a stop/start RADIUS accounting pair should be sent to the RADIUS server when an applicable R-P event occurs.


Usage:

Use this command to configure the events for which a RADIUS event is sent to the server when the accounting procedures vary between servers.


Example:
The following command enables an R-P event (and therefore a RADIUS accounting event) when an Active-Stop is received from the PCF:

ip_address [ port port_number ]

Specifies the IP address of the accounting server. ip_address must be specified using IPv4 dotted-decimal notation. A maximum of 1600 RADIUS servers per context/system and 128 servers per server group can be configured. This limit includes accounting and authentication servers.

port port_number specifies the port number to use for communications. port_number must be an integer from 0 through 65535. Default is 1813.

IMPORTANT:

The same RADIUS server IP address and port can be configured in multiple RADIUS server groups within a context.

[ encrypted ] key value

Specifies the shared secret key used to authenticate the client to the servers. The encrypted keyword indicates the key specified is encrypted.

In 12.1 and earlier releases, the key value must be an alphanumeric string of 1 through 127 characters without encryption, and 1 through 256 characters with encryption.

In StarOS 12.2 and later releases, the key value must be an alphanumeric string of 1 through 127 characters without encryption, and 1 through 236 characters with encryption enabled.

The encrypted keyword is intended only for use by the chassis while saving configuration scripts. The system displays the encrypted keyword in the configuration file as a flag that the variable following the key keyword is the encrypted version of the plaint text key. Only the encrypted key is saved as part of the configuration file.

acct-on { disable | enable }

Enables and disables sending of the Accounting-On message when a new RADIUS server is added to the configuration.

When this is enabled, the Accounting-On message is sent when a new RADIUS server is added in the configuration. However, if for some reason the Accounting-On message cannot be sent at the time of server configuration (for example; if the interface is down), then the message is sent as soon as possible. Once the Accounting-On message is sent, if it is not responded to after the configured RADIUS accounting timeout, the message is retried the configured number of RADIUS accounting retries. Once all retries have been exhausted, the system no longer attempts to send the Accounting-On message for this server.

Default: disable

acct-off { disable | enable }

Disables and enables the sending of the Accounting-Off message when a RADIUS server is removed from the configuration.

The Accounting-Off message is sent when a RADIUS server is removed from the configuration, or when there is an orderly shutdown. However, if for some reason the Accounting-On message cannot be sent at this time, it is never sent. The Accounting-Off message is sent only once, regardless of how many accounting retries are enabled.

Default: enable

max max_messages

Specifies the maximum number of outstanding messages that may be allowed to the server.

max_messages must be an integer from 1 through 256.

Default: 0

max-rate max_value

max_value must be an integer from 0 through 1000.

Default: 0 (disabled)

oldports

Sets the UDP communication port to the out of date standardized default for RADIUS communications to 1646.

priority priority

Specifies the relative priority of this accounting server. The priority is used in server selection for determining which server to send accounting data to.

priority must be an integer from 1 through 1000, where 1 is the highest priority. When configuring two or more servers with the same priority you will be asked to confirm that you want to do this. If you use the -noconfirm option, you are not asked for confirmation and multiple servers could be assigned the same priority.

Default: 1000

This option is available only when nexthop-forwarding gateway is also configured with nexthop-forwarding-address nexthop_address keyword and aaa-large configuration is enabled at Global Configuration level.


Usage:

This is necessary for NetWare Access Server usage such as the system must be identified to the NAS.

The system supports the concept of the active nas-ip-address. The active nas-ip-address is defined as the current source ip address for RADIUS messages being used by the system. This is the content of the nas-ip-address attribute in each RADIUS message.

The system will always have exactly one active nas-ip-address. The active nas-ip-address will start as the primary nas-ip-address. However, the active nas-ip-address may switch from the primary to the backup, or the backup to the primary. The following events will occur when the active nas-ip-address is switched:
  • All current in-process RADIUS accounting messages from the entire system are cancelled. The accounting message is re-sent, with retries preserved, using the ne w active nas-ip-address. Acct-Delay-Time, however, is updated to reflect the time that has occurred since the accounting event. The value of Event-Timestamp is preserved.
  • All current in-process RADIUS authentication messages from the entire system are cancelled. The authentication message is re-sent, with retries preserved, using the new active nas-ip-address. The value of Event-Timestamp is preserved.
  • All subsequent in-process RADIUS requests uses the new active nas-ip-address.
The system uses a revertive algorithm when transitioning active NAS IP addresses as described below:
  • If the configured primary nas-ip-address transitions from UP to DOWN, and the backup nas-ip-address is UP, then the active nas-ip-address switches from the primary to the backup nas-ip-address.
  • If the backup nas-ip-address is active, and the primary nas-ip-address transitions from DOWN to UP, then the active nas-ip-address switches from the backup to the primary nas-ip-address.

Example:
The following command configures the RADIUS identification parameter, NAS IP address to 10.2.3.4.

no

Disables the configured IP Virtual Routing and Forwarding (VRF) context instance and removes the association between the VRF context instance and the AAA group instance (NAS-IP).

By default this command is disabled, which means the NAS-IP being used is assumed a non-VRF IP and specific AAA group does not have any VRF association.

vrf_name

Specifies the name of a pre-configured VRF context instance.

vrf_name is the name of a pre-configured virtual routing and forwarding (VRF) context configured in Context configuration mode through ip vrf command.

CAUTION:

Any incorrect configuration, such as associating AAA group with wrong VRF instance or removing a VRF instance, will fail the RADIUS communication.


Usage:

Use this command to associate/disassociate a pre-configured VRF context for a feature such as BGP/MPLS VPN or GRE, and IPSec tunneling which needs VRF support for RADIUS communication.

By default the VRF is NULL, which means that AAA group (NAS-IP) is associated with global routing table and NAS-IP being used is assumed a non-VRF IP.

This IP VRF feature can be applied to RADIUS communication, which associates the VRF with the AAA group. This command must be configured whenever a VRF IP is used as a NAS-IP in the AAA group or at the Context level for the “default” AAA group.

This is a required configuration as VRF IPs may be overlapping hence AAA needs to know which VRF the configured NAS-IP belongs to. By this support different VRF-based subscribers can communicate with different RADIUS servers using the same, overlapping NAS-IP address, if required across different AAA groups.


Example:
The following command associates VRF context instance ip_vrf1 with specific AAA group (NAS-IP):
radius ip vrf ip_vrf1
