Setting Up Individual IP Addresses

If your application uses a load balancer, you can give the users individual IP addresses by using the System Configuration Manager.

  1. From the Silk Performer menu bar, select Tools > System Configuration Manager . The System Configuration Manager dialog box appears.
  2. Click the IP Address Manager tab. From the Adapter list box, select the network adapter for which you want to configure IP addresses. The list contains all the network adapters to which IP is bound on the computer in question.
  3. Use the IP addresses area to find out information about the current configuration of the network adapter, and to set up IP addresses for the adapter.
  4. To add new IP addresses to the network adapter configuration, click the Add button. The Add IP Addresses dialog opens.
  5. On the Add IP Addresses dialog, specify the following:
    1. In the From IP address field, enter the IP address you want to add to the network adapter configuration. If you specify that you want to add multiple addresses, the System Configuration Manager generates sequential IP addresses, starting with this address.
    2. In the Subnet mask field, enter the subnet mask number for the IP addresses.
      Note: This number, combined with the IP addresses, identifies which network the computers are on.

      To add multiple IP addresses, either select the Number option and enter the number of addresses you want, or select the To IP address option.

      In the latter case, specify the highest IP address you want to add to the network adapter configuration. The System Configuration Manager generates sequential IP addresses, starting with the address you type in the From IP address field and ending with this address.

    3. Select the Do not add conflicting addresses option to only add IP addresses to the network adapter configuration that do not cause conflicts.
    4. When enabling the Allow CIDR addresses check box, the verification of the IP address and subnet mask pair is disabled. Classless Inter-Domain Routing (CIDR) has been adopted as a solution to the scaling problem in the Internet. CIDR is not as restrictive as the "normal" IP-Routing.
    5. Click OK.
    Tip: To edit a selected IP address, click the Edit button.
  6. To save the network adapter configuration to a file, click the Save button. By default, the file is stored in the System Configuration Manager home directory. To load a network adapter configuration from a file, click the Load button and locate the appropriate file.
  7. To remove IP addresses, click the Remove button.
    CAUTION:
    Be cautious about removing multiple IP addresses at once.
    The Remove IP Addresses dialog appears.
  8. On the Remove IP Addresses dialog, specify the following:
    1. In the From IP address field, enter the IP address you want to remove from the network adapter configuration. If you elect to remove multiple addresses, the System Configuration Manager deletes all successive IP addresses, starting with this address.
    2. In the Subnet mask field, enter the subnet mask number for the IP addresses you want to remove.
    3. To remove multiple IP addresses, select either the Number or the To IP address option. Select the Number option to specify the number of IP addresses you want to remove from the network adapter configuration, and enter the number of addresses in the field. The System Configuration Manager deletes that number of successive IP addresses, starting with the address you type in the From IP address field. Select the To IP address option to specify the highest IP address you want to remove from the network adapter configuration. The System Configuration Manager deletes all successive IP addresses, from the address you type in the From IP address field to this address.
    4. Click OK.
  9. If you want to check whether IP routing to a specified computer works for all configured IP addresses, enter the name or IP address of the computer in the Host name or IP address field in the Network area, then click Check. A report from this check will be provided at the bottom of the dialog.
  10. Click OK to exit the dialog and save your changes.
