> SGSN Service Configuration Mode Commands
> The SGSN Service configuration mode is used within the global configuration mode to specify the 3G operations of the SGSN and the available SGSN services for a specific context.
> SGSN Service works with MAP Service, SGTP Service, GTPP Group, and IuPS Service. All five of these services must be configured to enable a 3G SGSN to communicate with other elements within a UMTS network.
> In this mode, the command prompt should appear like:
> [<ctx_name>]hostname(config-sgsn-service)#
> Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

> Security Administrator, Administrator
> Syntax
> admin-disconnect-behavior { clear-subscription | detach-type { reattach-not-required | reattach-required } }
> [ default | no ] admin-disconnect-behavior { clear-subscription | detach-type }
> clear-subscription
> Including this keyword in the configuration instructs the SGSN to clear subscriber contexts and the subscription data database whenever the clear subscribers all command is issued (from the Exec mode) for attached subscribers. As well, the SGSN will issue an appropriate Map-Purge-MS-Req to the HLR if needed.
> Default: disabled
> detach-type
> Including this keyword defines which type of detach instruction to include in the Detach-Request message during an Admin-Disconnect procedure. One of the following options must be included when this command is entered:

> • | reattach-not-required

> • | reattach-required

> Default: reattach-required
> default | no
> Including either default or no keyword in the command, instructs the SGSN to use the default value for the specified parameter.
> Usage
> Include the clear-subscription keyword with this command configuration to ensure that more than attached MM-context and active PDP-contexts are cleared when the clear subscribers all command is issued for attached subscribers.
> To clear subscription data for detached subscribers, refer to the sgsn clear-detached-subscriptions command described in the Exec mode chapter.
> Including the detach-type keyword with this command instructs the SGSN to include either a ‘reattach-required’ or a ‘reattach-no-required’ instruction in the Detach-Request message.

> Privilege
> Security Administrator, Administrator
> Syntax
> check-imei { gf-failure-action | gf-timeout-action } { continue | reject }
> default check-imei { gf-failure-action | gf-timeout-action }
> default
> Resets the default function to reject the Attach.
> gf-failure-action
> Coupled with either continue or reject, this keyword instructs the SGSN to take action if a valid EIR configuration exists under the MAP service and if the EIR is temporarily unreachable due to associated DPC/SSN inaccessible/out-of-service.
> gf-timeout-action
> Coupled with either continue or reject, this keyword instructs the SGSN to take action if a valid EIR configuration exists under the MAP service and the route to the EIR is available, but no response is received from the EIR.
> continue
> Instructs the SGSN to continue the Attach process.
> reject
> Instructs the SGSN to reject the Attach process.
> Usage
> Typically, the Attach process will be continued when there is an IMEI check timeout based on the configuration under the SGSN service configuration and/or the GPRS service configuration. But this works only if the route towards the EIR is UP and the IMEI request timer expires. This command configures the SGSN to allow the Attach process to continue in the case the route towards the EIR is down, that is the DPC / SSN is out-of-service.
> Example
> Use the following command to reset the default and reject Attach:
> default check-imei gf-failure-action
> check-imei-timeout-action
> In Releases 12.0 and higher, this command has been replaced with enhanced functionality in the check-imei command, also available in this configuration mode.

> Usage
> Use this command to identify the SGSN identified with the NRI in the MS generated P-TMSI.
> This command adds or removes the Iu Flex configuration for this SGSN service. When using Iu Flex, all keywords must be defined. The command can be repeated to specify different values for any of the keyword parameters. If more than one NRI is configured, the SGSN service will round-robin between the available NRIs when new subscribers (re)connect.
> Use this command to retrieve the NRI (identity of an SGSN) stored in in bits 23 to 18 of the packet-temporary mobile subscriber identity (P-TMSI). If more than one NRI value is configured, the SGSN service will round-robin between the available NRIs when new subscribers (re)connect.
> When using MOCN mode for network sharing without SGSN pooling, the NRI length and the NRI value should both be used.

> This command is one of the steps needed to enable the SGSN to create a log for events such as Attach, RAU, and Activations. The log is an EDR (event data record) in CSV format. For details about how this feature works, refer to the GMM-SM Event Logging chapter in the SGSN Administration Guide.
> Related Commands:

> • | To enable GMM/SM event logging for 2G services, the reporting-action event-record command must be configured in the GPRS service configuration.

> • | To enable a log to be generated in an EDR file, the edr-module active-charging-service command must be enabled in the Context configuration mode.

> • | To configure parameters for the logging file characteristics and for file transfer, use the commands in the EDR Module Configuration Mode.

> Example
> Enable GMM/SM event logging for 3G services:
> reporting-action event-record
> sgsn-number
> This command defines the E.164 number that identifies this particular SGSN service context.
> Product
> SGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> sgsn-number E.164_number
> no sgsn-number
> no
> Removes the SGSN number configuration from the SGSN service configuration.
> E.164_number
> Enter a maximum of 15 digits to define the ‘phone’ number associated with this SGSN service in the specified context.
> Usage
> The SGSN supports multiple SGSN numbers – different numbers in the 2G GPRS service configuration and the the 3G SGSN service configuration. If an HLR-initiated dialog is received, the SGSN will perform a lookup based on the IMSI and find the correct SGSN number with which the MS is associated. Subsequent messaging will use this address.
> Example
> To delete the sgsn-number associated with this SGSN service context, enter:
> no sgsn-number
> sgtp-service
> This command creates an instance of an SGTP service.

> default sm timer
> default
> Resets the selected timer to the system default value.

> max-modf-retransmission
> Configures maximum retries for modify PDP ctxt request. Default is 4
> Usage
> Repeat the command to configure multiple session management parameters for the SGSN service.
