System and Instance Naming Conventions

System and instance names are assigned during instantiation. You can edit the userdata values that specify these names in the template file you are using during instantiation. Refer to Instantiating SBC SWe on OpenStack using Heat Templates or Instantiating SBC SWe on AWS. If you deploy using VNFM, you can set the system name during the instantiation process. The default instance names are set within the VNFD file. Refer to Instantiating SBC SWe on OpenStack using VNFM.

System Naming Convention

The system name is used in billing, external PSX queries (if applicable), and system logs. On an HA system, one system name applies to both units and each unit has its own instance name as described in the Instance Naming Convention section. 

An example system name is WFDSBC01, where:

• The first three letters represent the physical location of the system (WFD =  Westford).
• The second three letters identify the system type (SBC).
• The last two digits identify the SBC (or SBC pair) instance at this particular location.
  
  

The following table lists system naming convention to follow while setting up SBC SWe systems:

SBC System Naming Convention

Convention/Character	System Name	Use as Leading Character	Use as Trailing Character
Maximum number of characters	26
Letters  [ a-z ] | [ A-Z ]
Digits [ 0-9 ]
Hyphen [ - ]
Period [ . ]
Underscore [ _ ]
Other special characters

Instance Naming Convention

If you are providing an instance name, the instance must be configured with the same name and used for all accounting, logging, PSX and EMS communications. The instance name is specific to an instance.

The following table lists the instance naming convention to follow while setting up SBC SWe systems:

SBC Hostname/Instance Naming Convention

Convention/Character	Instance Name	Use as Leading Character	Use as Trailing Character
Maximum number of characters	64
Letters  [ a-z ] | [ A-Z ]
Digits [ 0-9 ]
Hyphen [ - ]
Period [ . ]1
Underscore [ _ ]2
Other special characters

VNFC and Cluster Naming Convention

The following table lists VNFC and Cluster naming convention to follow while instantiating VNFC and creating clusters:

VNFC and Cluster Naming Convention

Convention/Character	Instance Name	Use as Leading Character	Use as Trailing Character
Maximum number of characters	64
Letters  [ a-z ] | [ A-Z ]
Digits [ 0-9 ]
Hyphen [ - ]
Period [ . ]1
Underscore [ _ ]2
Other special characters

Checking the Instance Name using CLI

To know the instance names, execute show table system serverAdmin. In the example, vsbc1 is the ceName provided in the userdata.

admin@vsbc1> show table system serverAdmin
       ACTUAL

vsbc2  none    default   secondary  false    ConnexIP5000  -           virtualCloud

Checking the System Name using CLI

To know the system name, execute show table system admin actualSystemName. In the below example, vsbcSystem is the system name given in the userdata.

admin@vsbc1> show table system admin actualSystemName
