This section defines the CLI syntax and parameters used to configure 

ENUM Domain Name

Command Syntax

% set global servers enumDomainName <domain_name>
	forwardersData <0-99999>
		forwarderDescription <description>
		forwarderIP <IPv4 or IPv6 address>
	loadDistribution <proportion | roundRobin | sequence> 
	queryRetryTimer <0-10000 ms>
	zoneType individual

Command Parameters

Note

All forwarderIP entries for this enumDomainName must be configured with the same loadDistribution type and queryRetryTimer value because attributes apply to ENUM domain, not individual forwarderIP entries.

Note
Refer to ENUM Support for additional feature details and descriptions.

ENUM Domain Name Parameters

Parameter

Length/Range

Description

<domain_name>1-63 characters

The name of the ENUM domain containing forwarderIP entries for load balancing.

forwardersData0-99999

<priority #> – Priority or sequence number of each forwarderIP defined below. A lower value represents a higher priority. This value is unique for each forwarderIP.

  • forwarderDescription <description> – Textual description of each fowarderIP entry.
  • forwarderIP <IPv4 or IPv6 address> – ENUM server IPv4 or IPv6 address of this forwarderIP entry.
loadDistributionN/A

Load distribution strategy. Refer to ENUM Support for details.

  • proportion
    • percentageDistribution – The percentage of load distribution to calculate for each IP in enumDomainName (range: 0-99999).
  • roundRobin
  • sequence (default)
queryRetryTimer0-10000

The time, in milliseconds, that SLWRESD process waits before trying the next IP in the forwardersData list (default = 4000).

zoneTypeN/A

The zone type for this ENUM domain.

  • individual – At present, this is the only zone type available, and it indicates the SBC supports load balancing across individual zones).

ENUM Domain Name Label

Command Syntax

% set global servers enumDomainNameLabel DEFAULT_ZONE_LABEL enumDomainNameId <enumDomainName's name>

Command Parameters

ENUM Domain Name Label Parameters

Parameter

Description

enumDomainNameLabel

<ENUM domain name label> – A collection of ENUM domains used by SLWRESD process for performing ENUM queries. The default enumDomainNameLabel value is "DEFAULT_ZONE_LABEL".

  • enumDomainNameId <enumDomainName's name> – The enumDomainName of each ENUM domain to attach to this enumDomainNameLabel.

ENUM Service

To support ENUM services for the SBC in ERE mode, manually create an ACL rule towards ENUM server to allow the packets (ENUM responses) from ENUM server into the SBC. See the CLI example below.

Note

Set fillRate to a higher value (for example, fillRate = 2000) to support high ENUM call loads (more than 20 cps). Refer to IP Access Control List - Cloud - CLI for configuration details.

Example ACL Rule
% set addressContext default ipAccessControlList rule ENUMSEV precedence 1 protocol any sourceIpAddress <ENUM_SERVER_ADDRESS> sourceAddressPrefixLength 32 action accept fillRate 50 bucketSize 50 state enabled 

 

Command Syntax

% set global servers enumService <name>
	criteria triggerCriteria <criteria>
	defaultTreatment <applyFinalTreatment | routeAsDialed>
	enumDefinitions privateDomainNameForEnumLookups <private_domain_name>
	flags 
		active <disable | enable>
		processCallingNumber <disable | enable>
		processNewANI <disable | enable>
	priority <129-140>
	requestTimeOut <0-2147483647>
	serviceType <cnam | lnp | sipAor>

 

Command Parameters

Global ENUM Service Parameters

Parameter

Length/Range

Description

<service_name>1-23ENUM Service name.
criteria1-23triggerCriteria <criteria> – Trigger criteria to use for this ENUM Service. The characters #%^&(){}<>,/\;`[]=!$"*?|~ and SPACE are not allowed.
defaultTreatmentN/A

Default treatment to apply to this ENUM Service.

  • applyFinalTreatment
  • routeAsDialed (default)
enumDefinitionsN/A

Use this parameter to specify how to treat ENUM definitions.

  • privateDomainNameForEnumLookups <private_domain_name> – Specify the private domain name to use for ENUM look-ups.
 flags N/A 
  • active
    • disable (default)
    • enable
  • processCallingNumber –Enable this flag to analyze the calling number using prefix profile. When this flag is disabled, the calling number is not analyzed and hence if it has +CC, the same is sent as-is to SBC in the calling number field in policy response.
    • disable (default)
    • enable
  • processNewANI – When this flag is enabled for ENUM AoR service, and ENUM AoR response contains "newani=<some_number>" parameter in NAPTR record, the ERE overwrites the existing calling number of the call with the newANI number. When this flag is disabled, any newANIparameters received in NAPTR response are ignored in PES.
    • disable (default)
    • enable
priority129-140

The priority (order) of ENUM service execution. If this parameter is not set or set to the default of '129', default priorities are assigned for LNP (130), CNAM (131) and SIP AoR (132). If a different order of service execution is desired, set the priorities accordingly.

For example, setting CNAM priority to 133 executes SIP AoR before CNAM.

requestTimeOut0-2147483647Request timeout value, in milliseconds. (default = 2000)
serviceTypeN/A

Use this parameter to specify the ENUM service type.

  • cnam
  • lnp
  • sipAor

 

  • No labels
