> Disables the configured CDR storage and CDR file processing in this mode:

> • | remove-file-after-transfer: Retains a copy of the file even after it has been pushed or pulled to another server.

> • | use-harddisk: Disables data storage on the SMC hard disk.

> Important: use-harddisk keyword is available only on the ASR 5000 chassis.

> Configures the default setting for the specified keyword(s):

> • | push-interval: 300 seconds

> • | push-trigger: 80 percent

> • | remove-file-after-transfer: Disabled

> • | transfer mode: Pull

> • | push via: LC is used for push

> • | use-harddisk: Disabled

> Important: use-harddisk keyword is only available on ASR 5000 chassis.
> push-interval value
> Specifies the transfer interval, in seconds, to push EDR and UDR files to an external file server.
> value must be an integer from 60 through 3600.
> Default: 300
> push-trigger space-usage-percent trigger_percentage
> Specifies the EDR/UDR disk space utilization percentage, upon reaching which an automatic push is triggered and files are transferred to the configured external server.
> trigger_percentage specifies the EDR/UDR disk utilization percentage for triggering push, and must be an integer from 10 through 80.
> Default: 80%
> remove-file-after-transfer
> Specifies that the system must delete EDR/UDR files after they are transferred to the external file server.
> Default: Disabled
> transfer-mode { pull | push primary { encrypted-url encrypted_url | url url } [ via local-context ] [ secondary { encrypted-secondary-url enc_sec_url | secondary-url sec_url} ] }
> Specifies the EDR/UDR file transfer mode.

> • | pull: Specifies that the L-ESS is to pull the CDR files.

> • | push: Specifies that the system is to push CDR files to the configured L-ESS.

> • | primary encrypted-url encrypted_url: Specifies the primary URL location in encrypted format to which the system pushes the CDR files.

> encrypted_url must be the location name in an encrypted format, and must be an alpha and/or numeric string of 1 through 1024 characters in length.

> • | primary url url: Specifies the primary URL location to which the system pushes the CDR files.

> url must be an alpha and/or numeric string of 1 through 1024 characters in the //user:password@host:[port]/directory format.

> • | via local-context: Configuration to select LC/SPIO for transfer of CDRs. The system pushes the UDR files via SPIO in the local context.

> • | encrypted-secondary-url enc_sec_url: Specifies the secondary URL location in encrypted format to which the system pushes the CDR files when the primary location is unreachable or fails.

> enc_sec_url must be the location name in an encrypted format, and must be an alpha and/or numeric string of 1 through 1024 characters in length.

> • | secondary-url sec_url: Specifies the secondary URL location to which the system pushes the CDR files when the primary location is unreachable or fails.

> sec_url must be an alpha and/or numeric string of 1 through 1024 characters in //user:password@host:[port]/directory format.
> use-harddisk
> Specifies that on ASR 5000 chassis the hard disk on the SMC be used to store EDR/UDR files. On configuring to use the hard disk for EDR/UDR storage, EDR/UDR files are transferred from RAMFS on the PSC to the hard disk on the SMC.
> Default: Disabled
> Important: use-harddisk keyword is available only on the ASR 5000 chassis.
> +
> Indicates that more than one of the previous keywords can be entered within a single command.
> Usage
> Use this command to configure how charging data records (CDR) are moved and stored.
> On the ASR 5000 chassis, run this command only from the local context. Running in any other context would fail and deliver an error message.
> The use-harddisk keyword is only available on the ASR 5000 chassis. This command can be run only in a context where CDRMOD is running. Configuring in any other context will result in failure with the message “Failure: Please Check if CDRMOD is running in this context or not.”
> This configuration can be applied either in the EDR/UDR module, but will be applicable both to the EDR and UDR modules. Configuring in one of the modules prevents the configuration to be done in the other module.
> If PUSH transfer mode is selected, the L-ESS server URL to which the CDR files need to be transferred to must be specified. The configuration allows a primary and a secondary server to be configured. Configuring the secondary server is optional. Whenever a file transfer to the primary server fails for four consecutive times, the files will be transferred to the secondary server. The transfer will switch back to the original primary server when:

> • | Four consecutive transfer failures to the secondary server occur

> • | After switching from the primary server, 30 minutes elapses

> When changing transfer-mode from pull to push, disable the PULL from L-ESS and then change the transfer mode to push. Make sure that the push server URL configured is accessible from the local context. Also, make sure that the base directory that is mentioned contains udr directory created within it.
> When changing transfer-mode from push to pull, after changing, enable PULL on the L-ESS. Any of the ongoing PUSH activity will continue till all the scheduled file transfers are completed. If there is no PUSH activity going on at the time of this configuration change, all the PUSH related configuration is nullified immediately.
> Example
> The following command configures the system to retain a copy of the data file after it has been transferred to the storage location:
> no cdr remove-file-after-transfer
> end
> Exits the current configuration mode and returns to the Exec mode.
