System - Admin Parameters

Parameter

Description

Name

Specifies the name of the SBC system.

Actual System Name

Specifies a system name assigned by the user using metadata or userdata (applies to SWe N:1 HA and cloud-based systems).

Note: If a system name was not assigned in this way, this field displays the system name.

HA Mode

Identifies the high-availability (HA) mode for the system.

  • haMode1to1 - Is the traditional HA/redundancy model (1:1 scenario) where one active instance is backed up by one standby instance. In 1:1 HA mode mode, the SBC configuration is synchronized between active and standby SBCs.
  • haModeNto1 - Is supported in SBC SWe cluster deployments where up to N active SBC instances are backed up by a single standby instance (N:1). In this mode, a 1:1 HA pair of dedicated Operations, Administration, and Maintenance (OAM) nodes is deployed to configure and manage SBC nodes. The SBC instances in such deployments have homogeneous configuration. The active OAM node holds the active configuration for the cluster and is responsible for sharing this configuration with the SBC nodes in the cluster.
Cluster IDSpecifies the unique alpha-numeric string for identifying the cluster to which the instance belongs as specified in userdata (applies only to SWe N:1 HA and cloud-based systems that are deployed as clusters that register with the Insight EMS).

Location

A user-editable field to specify the physical location of the SBC system.

Contact

A user-editable field to specify contact information for the SBC system.

Local Authentication Enabled

Specifies that Confd CLI user information stored locally can be used for authentication. Options are:

  • True (default)
  • False

External Authentication Enabled

Specifies that Confd CLI user information stored on a remote Radius Server can be used for authentication. Options are:

  • True
  • False (default)
External Authentication Type

Specifies the external authentication type. Set this option to ldap to use external authentication for LDAP.

  • Ldap
  • Radius (default)

Default Account Local Only

Specifies whether the default admin user must be locally authenticated. Options are:

  • True
  • False (default)

The option can only be set to True when the options that enable/disable local authentication on the SBC generally, Local Authentication Enabled and External Authentication Enabled, are also set to True. If both local and external (RADIUS) authentication are enabled on the SBC then the method for authentication of the default admin user is governed by this option.

Util Monitor Stats Interval

Specifies the time interval for system resource monitoring statistics. The value ranges from 5 to 60 minutes and the default value is 15 minutes.

Note:  

If using the EMS in your network, configure EMS PM data collection intervals for the SBC to be both:

  • Equal to or greater than the SBC interval size, and
  • Not less than the SBC interval size multiplied by the SBC number of intervals.

Refer to Insight EMS Documentation for configuration details.

Util Monitors Stats Num of Past Interval

Specifies the number of past intervals of the system resource monitoring statistics to save.

Audit Log State

Specifies the state of the management audit log. The options are:

  • Disabled
  • Enabled (default)

Dsp Mismatch Action

Specifies the action to take for one of the following DSP mismatch conditions:

  1. Mismatch in DSP card installation across any/all slot locations: Cards must match by slot location. For any mismatched slots, DSP capacity is not used when Preserve Redundancy is configured (and card dried up if calls were already in place when the mismatch occurred), or card is left unprotected when Preserve Capacity is configured.
  2. Mismatch in DSP card type within a slot location: Card installations must match by type – DSP25 (higher capacity) or DSP20 (lower capacity). Same rules as above apply.

The options are:

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

Note: During the dry-up period, active calls using the higher capacity DSPs are not protected in the event that a switchover occurs before the dry up completes.

  • Preserve Capacity: The active SBC continues to use the extra DSP capacity, as needed, assuming appropriate session licenses are in place; partial redundancy is in effect.

Note: If a switchover occurs, calls using the higher capacity DSPs on the active instance are not protected during switchover (that is, partial redundancy).

Cli Set Warning Support

Specifies whether or not to enable warning prompts configured for the Set commands. The options are:

  • Disabled
  • Enabled (default)
Verify Auto Index

Set this value to True to specify that the SBC should check before it adds a new entry to a configuration table that has an Auto Index column to that the newly assigned Auto Index value does not already exist in that table. The transaction fails if the configuration database (CDB) already uses that Auto Index number. Provisioning can be slow when this check is enabled since the CDB is queried for each item that uses an Auto Index number. Therefore this option should only be set to True when directed by Technical Support. The options are:

  • False (default)
  • True
Ssh Public Key Authentication Enabled

If set to True and the SSH keys are populated, SSH users can log into their servers without the need to enter their passwords.

  • False (default)
  • True
Ssh Max Auth TriesSpecifies the maximum number of times SSH users can attempt authentication before an account is locked. The valid range is 2 to 6. The default value is 6.

Admin Commands

Use the Admin commands to perform system administration actions such as restart and regenerating SSH encryption keys. A partial list of the commands appears in the following figure.

Admin Commands


Select one of the commands and click Select.  A pop-up window opens where you can specify any required command options and initiate the selected command. Some commands are only available in cloud-based deployments.

The commands are:


Admin Commands

Parameter

Description

Ad Manual SyncUse this command to initiate a request to sync with the Active Directory (AD) server to retrieve subscriber data.
Delete Config Store File

Use to delete a configuration file on an external cloud object store service.

Note: This action command is applicable only for SBC SWe N:1 HA and cloud-based deployments.

Discard Candidate ConfigurationUse to discard candidate configuration changes that have been committed on the OAM node, but not yet activated on the managed SBC nodes with the saveAndActivate command. This command also restarts the OAM nodes, although it does not impact the managed SBC nodes. Applies only to SBC SWe cluster deployments operating in OAM configuration mode.
Re Generate Ssh Rsa KeysUse this command to regenerate all SSH keys.

Re Key Confd Encryption Key

Soft ResetUse this command to restart the applications on the system without rebooting the server(s).
SwitchoverUse this command to perform a switchover of the management applications and restart all applications on currently active server.
Verify Database Integrity

Use this command to verify that the SBC policy and configuration databases on the active server are in sync and that the policy databases on the active and standby servers are in sync. Because these commands take a few seconds to execute, it is not advisable to run these commands repeatedly on the system. In the pop-up window, specify the following:

  • Active And Standby Policy – Check if policy databases on the active and standby servers are in sync.
  • Active Config And Active Policy – Check if the policy and configuration databases on the active server are in sync.
  • All – Perform both of the above checks.
View Configuration Changes

Use to review the list of changes associated with a specified revision. Specify the revision number in the pop-up window provided.

Note that viewing of configuration related to lawful intercept (LI) is restricted to authorized users and therefore output is filtered accordingly. LI-related changes are not present in the output shown to users that lack LI privileges. Similarly, users with only LI privileges can see only LI-related configuration changes.
