> 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, refer to the RADIUS Server State Behavior appendix in the AAA and GTPP 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
> radius 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 IPv4/ipv6 address of the server.
> ip_address must be specified in dotted decimal notation for IPv4 or colon notation for IPv6. 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

> Important: For a complete explanation of RADIUS server states, refer to the RADIUS Server State Behavior Appendix in the AAA and GTPP 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

> 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.

> 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.

> 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:

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

> 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.

> Syntax
> radius ip vrf vrf_name
> no radius ip vrf
> 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 ‘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.
