In this section:


Use this window to specify Lwresd Profile configuration. Currently, the SBC supports only one Lwresd Profile (DEFAULT). Deletion of the default profile is not allowed but it can be edited.

By default the SBC sends ENUM queries from the management interface (Type option = Mgmt). You have the option to send them through a packet interface (Type option = IP) or through the signaling interface using the SIP Signaling Port IP address (Type option = Signaling IP). different options must configured depending on your choice.

To View Lwresd Profile

On the SBC main screen, navigate to All > Global > Servers > Lwresd Profile. The Lwresd Profile window displays.

To Edit the Lwresd Profile

To edit the Lwresd Profile:

Click the radio button next to the name DEFAULT. The Edit Selected Lwresd Profile window opens with the Type set as Mgmt by default, as in the following figure. When you select a different type, the options on the window change as shown in the figures that follow.

Use the following table to configure the options that appear for the Type you have chosen and click Save.

Table 1: Lwresd Profile Parameters

ParameterDescription
Name

Profile name used by the SLWRESD process. The default profile name is DEFAULT. The SLWRESD process uses the ENUM zones configured for performing an ENUM query against Enum Domain Label.

DescriptionTextual description of Lwresd Profile (length: 1-255 characters).
ENUM Domain Label Name 

The ENUM domain name label created for Enum Domain Name Label entity. Use this parameter to associate the Lwresd Profile with a particular Enum Domain Name Label.

Currently, SBC supports only one label name (DEFAULT_ZONE_LABEL).

Enable Lwresd LogUse this flag to enable/disable the LWRESD log.
  • Disable (default)
  • Enable
ENUM ARS Profile IDSelect the name of the ENUM Address Reachability Service (ARS) profile you want to use. This profile applies to ENUM servers and specifies behavior for managing device failover to a secondary or backup ENUM server in the form of blacklisting and whitelisting parameters. Refer to Global - Servers - ENUM ARS Profile for more information.
Type

Use this parameter to specify the interface to use to send ENUM queries. Your choice for this option changes the other options that are available on the window.

  • Mgmt (default)
  • IP
  • Signaling IP
Address Context

Select the Address Context for the IP Interface Group you want to use.

This parameter is only visible if Type is set to IP or Signaling IP.

IP Interface Group

Select the name of the IP Interface Group to use for sending ENUM queries.

This parameter is only visible if Type is set to  IP or Signaling IP.

E Dns Global Buffer SizeUse this parameter to specify the buffer size to use for OPT records when a buffer size is not configured at the individual ENUM Domain Name level. Refer to Global - Servers - ENUM Domain Name. The default value is 4096 and the range allowed is 512 to 4096.
E Dns Monitor IntervalUse this parameter to specify an interval during which the ERE does not send eDNS queries after a DNS server sends an eDNS failure response. During this interval value, the ERE instead sends DNS queries. The default value is 120 and the range allowed is 60 to 180.
Zone

Select the Zone for the IP Interface Group you want to use.

This parameter is only visible if Type is set to Signaling IP.

SIP Sig Port

Select the SIP signaling port to that specifies the IP address to use for sending ENUM queries. The signaling interface uses port 988 to send and receive the queries.

This parameter is only visible if Type is set to Signaling IP.

To configure the SBC to use the appropriate interface for handling ENUM queries, sequentially perform the following configuration steps:

For using the Packet Interface:

  1. Add the intended Static Route to the ENUM server. For further details on creating a Static Route, refer to  System Provisioning - Static Route.
  2. Set the Type parameter of the Lwresd Profile as IP. See the To Edit Lwresd Profile section in this page.
  3. Add an IP Access Control List (ACL) rule to get the response of the ENUM Queries. For further details on adding ACL rules, refer to Ip Access Control List - Rule.

For using the Signaling Interface:

  1. Add the intended Static Route to the ENUM server. For further details on creating a Static Route, refer to  System Provisioning - Static Route.
  2. Set the Type parameter of the Lwresd Profile as Signaling IP. See the To Edit Lwresd Profile section in this page.

For using the Management Interface (default):

  1. Delete the Static Route (if any) from the list of Static Routes added to the ENUM Server. For further information on deletion of Static Routes, refer to  System Provisioning - Static Route.
  2. Set the Type parameter of the Lwresd Profile as Mgmt. See the To Edit Lwresd Profile section in this page.
  3. Add an IP Access Control List (ACL) rule to get the response of the ENUM Queries. For further details on adding ACL rules, refer to Ip Access Control List - Rule.
