Configuring the SBC for ENUM Queries

Overview

The SBC sends ENUM queries and receive responses, using the Signaling Interface. The user can configure the Signaling Interface for sending ENUM queries and receive responses, using the packet interface port 988. The packets from the Signaling Interface are prioritized over the packets from the Management Interface.

The SBC uses the Management Interface as default for handling ENUM queries. There are two ways to handle ENUM queries:

• Handling the ENUM Queries Using the Signaling Interface
• Handling the ENUM Queries Using the Management Interface

Handling the ENUM Queries Using the Signaling Interface

To configure the SBC for sending the ENUM queries and receive responses using the Signaling Interface, perform the following steps:

1. Checking Static Routes Currently Configured for an ENUM Server [optional]

   % show addressContext default staticRoute

   Sample Output for IPV4

   staticRoute 10.54.78.21 32 10.54.24.1 LIG001 LIF1_v4 {
   preference 100;
   }
   

   Sample Output for IPV6

   staticRoute fd00:10:6b50:44e0::15 60 fd00:10:6b50:4180::1 LIG001 LIF1_v4 {
   preference 100;
   }

2. Adding a Static Route for an ENUM Server

   Note:

   It is not necessary to add a Static Route for an ENUM server, if it is already configured and shown in the output of the command "show addressContext <addressContext_Name> staticRoute".

   For example, if the ENUM server IP 10.128.254.116 is already added as a static route, then the output of the "show addressContext default staticRoute" command displays the following information:

   staticRoute 10.128.254.116 32 10.54.4.1 LIG001 LIF1_v4 {

       preference 120;

   }

   For IPV4

    % set addressContext default staticRoute 10.128.254.116 32 10.54.4.1 LIG001 LIF1_v4 preference 120
   commit

   For IPV6

   % set addressContext DEFAULT staticRoute fd00:10:6b50:44e0::15 60 fd00:10:6b50:4180::1 LIG001 LIF1_v4 preference 177
   commit

3. Setting lwresdProfile to ip

   % set global servers lwresdProfile DEFAULT type ip addressContext default ipInterfaceGroup LIG001
   commit

4. Viewing the lwresdProfile [optional]

   % show global servers lwresdProfile DEFAULT

   Sample Output

   description                       DEFAULT;
   ENUMDomainNameLabel               DEFAULT_ZONE_LABEL;
   enableLwresdLog                   disable;
   type                              ip;
   addressContext                    default;
   ipInterfaceGroup                  LIG001;

   Note:

   The parameters addressContext and ipInterfaceGroup appears in the results of the command "show global servers lwresdProfile DEFAULT", only if the parameter lwresdProfile type is set to ip.

5. Adding an ACL Rule

   For IPV4

   % set addressContext default ipAccessControlList rule DNS1 precedence 9 ipInterfaceGroup LIG2 ipInterface LIF2_v4 sourceIpAddress 10.128.254.1 sourceAddressPrefixLength 24 state enabled
   commit

   For IPV6

   % set addressContext DEFAULT ipAccessControlList rule DNS1 precedence 11 ipInterfaceGroup LIG001 ipInterface LIF1_v4 sourceIpAddress fd00:10:6b50:4020::99 sourceAddressPrefixLength 60 state enabled
   commit

Handling the ENUM Queries Using the Management Interface

To configure the SBC for sending the ENUM queries and receive responses using the Management Interface, perform the following steps:

1. Deleting the Existing Static Routes for an ENUM Server

   Note:

   The SBC selects the interface based on priority of the static route configured for interface. To enable the Management Interface for handling ENUM queries, delete static routes configured for the ENUM server.

   
   For IPV4

   % delete addressContext default staticRoute 10.128.254.116 32 10.54.4.1 LIG001 LIF1_v4
   commit

   For IPV6

   % delete addressContext default staticRoute fd00:10:6b50:44e0::15 60 fd00:10:6b50:4180::1 LIG001 LIF1_v4
   commit

2. Setting lwresdProfile to mgmt

   % set global servers lwresdProfile DEFAULT type mgmt
   commit

3. Viewing the Settings of lwresdProfile [optional]

   % show global servers lwresdProfile DEFAULT

   Sample output:

   description                       DEFAULT;
   ENUMDomainNameLabel               DEFAULT_ZONE_LABEL;
   enableLwresdLog                   disable;
   type                              mgmt;
   

4. Adding an ACL Rule

   For IPV4

   % set addressContext default ipAccessControlList rule DNS1 precedence 9 sourceIpAddress 10.54.92.180 sourceAddressPrefixLength 24 state enabled
   commit

   For IPV6

   % set addressContext DEFAULT ipAccessControlList rule DNS1 precedence 11 sourceIpAddress fd00:10:6b50:4020::99 sourceAddressPrefixLength 60 state enabled
   commit
