In this section:

Use the system parameter sweConfigProfileSelection to configure the SBC SWe provisioning limits based on the following profiles:

  • extrasmall
  • small
  • large
  • largeuseracl

Command Syntax

% set system sweConfigProfileSelection name <extrasmall | large | largeuseracl | small>


Command Parameters

Parameter

Description

name

This parameter indicates the name of the configuration provisioning profile to apply.

The profile options are:

  • extrasmall – applicable when the VM RAM is between 6 and 10 GiB
  • large – applicable when the VM RAM is >=18 GiB
  • largeuseracl – applicable when the VM RAM is >=18 GiB  (supports up to 10,5926 IP ACLs)
  • small (Default) – applicable when the VM RAM is >=10 GiB
Note

When an instance comes up in an environment which has between 6 and 10 GB of memory, the value for sweConfigProfileSelection is automatically set to extrasmall. It is not valid to reconfigure a deployment from one of the larger sizes (small, large, or largeuseracl) to the extrasmall size.

For feature provisioning limits of the large, largeuseracl and small profiles, refer to SBC Provisioning Limits. 
For feature provisioning limits of the extrasmall profile, refer to Small SBC SWe Deployment Characteristics.

Command Example

set system sweConfigProfileSelection name large
 
The following warnings were generated:
'system sweConfigProfileSelection':To Activate the configuration profile system will be rebooted. Operator to confirm that the existing configuration fits into the new profile being assigned to avoid unexpected behavior (Refer to Provisioning Limits section in Documentation). All active calls will be lost during this process. Do you wish to continue?
Proceed? [yes,no]
Note

The preceding warning applies to non-Cloud SBC SWe only.

The SBC does not support downgrading the SBC SWe Config Profile setting. For example, downgrading from large or largeuseracl to small, or small to extrasmall is not supported.

SBC N:1 Deployments

Activation of the SBC SWe Config profile from OAM is supported from SBC 9.0 onwards.

For extra small deployments, start up the SBCs as well as the OAM with <10 GB Memory. The default activated profiles of the SBC SWe config profile based on memory are provided in the following table:

SBC SWe Config Profile Based on Memory

The following table shows the SBC SWe Config profiles based on memory.

RAM on SBC and OAMSWe Config Profile
< 10GBextrasmall
>=10GBsmall

On the SBC, activate the SWe config profile using a manual reboot of all the managed SBCs under an OAM. For extrasmall deployments, all of the nodes in a redundancy group under an OAM node are extrasmall. That is, a separate OAM node is required to manage extrasmall nodes.

The OAM does not validate the H/W(Memory) resources on the SBC while activating a config profile. Therefore, ensure that adequate resources are provided to the SBCs for activating a config profile.

The OAM does not require a reboot for activation of config profile.

If you activate an SBC SWe config profile from the OAM, which requires a higher than available H/W resources on the SBC, it raises the alarm sonusConfigProfileActivationNotification with the corresponding failure reason.

Recovery Steps

Scenario 1: Attempt to downgrade the SBC SWe config profile

An attempt to downgrade the config profile raises the alarm sonusConfigProfileActivationNotification, with the corresponding reason of failure. Reboot the SBC to recover. Upon reboot, the SBC starts up with the unchanged SweConfigProfile, rejecting the downgrade request from the OAM.

Example:

If the initial SweConfigProfileSelection configuration on the SBC and the OAM is large and the operator commits and activates a small SBC SweConfigProfileSelection on the OAM, the SBC raises the failure alarm. When you reboot the SBC, the application starts up with the large configuration rejecting the small configuration as seen from the OAM.

To downgrade the SweConfigProfile from large to small, rebuild the SBC. In such scenarios, the SBC starts up with the small configuration, honoring the configuration from the OAM.

Scenario 2: Error due to requirement of hardware resources

Note

On the OAM, downgrading the SweConfigProfile from large to small is supported for recovery of the SBC instances.

  1. On the OAM, activate the SweConfigProfile as small. 
  2. Reboot all the SBCs under the OAM. Do not reboot the OAM.

The SBC starts up with the small config profile.
