Command Parameters

System Admin Parameters (set)

 

Parameter

Length/Range

Description

admin

N/A

Use this object to specify system name.

accountManagementN/A

Use this feature to manage system level account and password related settings. See Account Management Parameters table below for details.

auditLogState

N/A

Use this flag to specify the management audit log state.

  • disabled
  • enabled (default)

banner

1-23

Use this parameter to customize the post-login banner from EMA and CLI applications.

  • ackBanner – Enable flag to require user to acknowledge (accept) the banner before gaining access to the system each time the user logs into the system.
    • disabled (default)
    • enabled 
  • bannerText  – Use this parameter to specify the banner text to display when users login to EMA and CLI applications.

 

"Field Service" and "Operator" user types are not allowed to change the Login Banner configuration.

cliSetWarningSupport

N/A

When this flag is enabled, warning prompts are configured for the "set" command.

  • disabled
  • enabled (default)

contact

N/A

Use parameter to specify system contact information. (default is "Unknown")

dodN/A

Use this object to enable DoD mode, and to enable/disable CLI and/or EMA access for temporary troubleshooting and diagnostics.

  • cliAccess – Use this flag to temporarily enable CLI for troubleshooting and diagnostic while the SBC is in DoD mode.
    • disabled (default)
    • enabled
  • mode – Use this flag to enable/disable DoD Mode.
    • disabled (default)
    • enabled
  • pmAccess – Use this flag to temporarily enable EMA's Platform Mode for troubleshooting and diagnostic while the SBC is in DoD mode.
    • disabled (default)
    • enabled

Enabling CLI and/or EMA for DoD mode lowers the security posture of the SBC. Remember to disable CLI and PM access once troubleshooting and/or diagnostics is completed.

dspMismatchActionN/A

Use this parameter to specify the action to take if a DSP mismatch is detected between the active and standby servers. 

  • preserveCapacity – The Active 

    Unable to show "metadata-from": No such page "_space_variables"
    continues to use the extra DSP capacity, as needed, assuming appropriate session licenses are in place; partial redundancy is in effect.

    If a switchover occurs, calls using the extra, non-matching DSP capacity on Active are not protected during switchover (i.e. partial redundancy).

  • preserveRedundancy (default) – The Active automatically triggers a graceful dry-up in an attempt to align DSP hardware capabilities. Once dry-up completes, the Active SBC uses the protected, matching DSP capacity to preserve redundancy.

    During the dry-up period, active calls using the extra, non-matching DSP capacity are not protected in the event that a switchover occurs before the dry up completes.

externalAuthenticationEnabled

N/A

The confd CLI user information stored on remote RADIUS server is available for authentication.

  • false (default)
  • true
fips-140-2 modeN/A

 Use this object to enable FIPS-140-2 mode.

Command Parameters

System Admin Parameters (request)

 

Parameter

Description

loadConfig

Load saved configuration and restart the system without rebooting the servers.

  • allowOldVersion – This option is only intended for use to override checks for older releases which do not identify their version. In this case, the follow error results. Follow the instructions given:

    "There is no version identifier on the saved file. Use the allowOldVersion parameter only if you are sure the version of the saved configuration file is compatible with the running software version."
    • no
    • yes

  • filename – Enter the configuration file to load.

In a redundant system, using loadConfig restarts both CEs.

If "reason Configuration file version not compatible with current software version. matrixFileNotAvailable" error is returned, the lswuMatrixSBX5000.bin/lswuMatrixSBX5000.txt file is missing from the/opt/sonus directory. You must must restore these files from the release package of the currently running software with the name pattern of "sbc-V0X.YY.ZZRQQQ.x86_64.tar.gz". Unzip and untar the current release's tar.gz file in that directory, return to the CLI and perform the command again.

reGenerateSshRsaKeysUse this control to regenerate all SSH keys.
reKeyConfdEncryptionKeys

Use this control to regenerate system configuration database encryption keys.
