Data Interface Pairs - Getting Started

You can set up a data interface pair (DIP) between two clients by using the Control Panel or from the Client.

No more than one DIP should be created between two clients. If another interface is created, the clients will use only the newer defined interface pair.

From the Control Panel

  1. From the CommCell Console ribbon, click Control Panel.
  2. In the Control Panel window, under System, click Data Interface Pairs.

    The Data Interface Pairs Wizard appears.

  3. In the welcome page of the wizard, click Next.
  4. Choose the hosts to pair by selecting one host name from each list and clicking Next. The wizard shows existing defined interface pairs between those two hosts.
  5. If the pair you need is not already shown, click Add, and select one interface for each host.

    • If you do not find the network interface you are looking for in the list, you can type its name or IP address.
    • With remote computers, the network interface you specify for a host must be visible to the other host.

    Click Next.

  6. Review the state of the defined pairs, and select the pair to make active.

    • If more than one DIP is defined and active (as indicated by a check in the Status column), only the one added most recently is actually used. To ensure that the pair you want is used, deselect any others.

    Click Finish.

  7. To verify that the interface pair has been properly set up between the two clients, you can check the firewall configuration of one of the clients:
    1. From the CommCell Browser, navigate to one of the paired clients.
    2. Right-click the <Client> and click Properties.
    3. Click Advanced | Firewall Configuration | Summary.
    4. Under the section named [outgoing], which shows outgoing network routes from that host, look for the entry showing the two clients, with their respective interface names. For example, if you created an interface pair between ida34vm3 and ida34vm1_2, the entry for ida34vm3 should have this layout:

      ida34vm3 ida34vm1_2 type=dip local_iface=172.16.64.228 remote_iface=172.16.64.200

      where local_iface indicates the network interface that ida34vm3 will use to communicate with ida34vm1_2 on that host's remote_iface. The type=dip parameter indicates a data interface pair route.

    5. Here is an example firewall configuration summary for a server named rentacs, with a DIP connection to another server named servertest2_32bit:

From the Client Level

  1. From the CommCell Browser, navigate to one of the two client computers to connect. Right-click the <Client> | Properties.
  2. Click the General tab, then Advanced, then the Job Configuration tab.
  3. In the Data Interface Pairs area, click Add.
  4. The CommCell Browser populates the 1st Computer entry. Select the 2nd Computer, and click Next.
  5. If the pair you need is not already shown, click Add, and select one interface for each host.

    • If you do not find the network interface you are looking for in the list, you can type its name or IP address.
    • With remote computers, the network interface you specify for a host must be visible to the other host.

    Click Next.

  6. Review the state of currently defined pairs, and select the pair to make active.

    • If more than one DIP is defined and active (as indicated by a check in the Status column), only the one added most recently is actually used. To ensure that the pair you want is used, deselect any others.

    Click Next.

  7. Click Finish to create the new data interface pair.
  8. To verify that the interface pair has been properly set up between the two clients, you can check the firewall configuration of one of the clients:
    1. From the CommCell Browser, navigate to one of the paired clients.
    2. Right-click the <Client> and click Properties.
    3. Click the Firewall Configuration | Summary.
    4. Under the section named [outgoing], which shows outgoing network routes from that host, look for the entry showing the two clients, with their respective interface names. For example, if you created an interface pair between ida34vm3 and ida34vm1_2, the entry for ida34vm3 should have this layout:

      ida34vm3 ida34vm1_2 type=dip local_iface=172.16.64.228 remote_iface=172.16.64.200

      where local_iface indicates the network interface that ida34vm3 will use to communicate with ida34vm1_2 on that host's remote_iface. The type=dip parameter indicates a data interface pair route.
