Managing dynamic components for network containers

This topic describes working with the dynamic components of a network container. It contains the following sections:

Dynamic components of a network container

The dynamic components of the container are the networks associated with its selected blueprint and the load balancers associated with the networks.

After you specify the name, pod, and container blueprint of the network container you are creating, you next enable or disable the associated networks and load balancers. You can add tag data to a selected network.

Note

External and other networks might be marked as Locked; that is, you cannot enable or disable them from the Network Containers: Dynamic Components dialog box. You will receive an error message if you attempt to enable or disable a locked network. A load balancer or firewall that is marked as locked can be neither enabled nor disabled.

After you have provisioned a network container, you can perform the following:

  • Edit the network address and mask of a selected network. To change the network address and mask of a network, you must first disable the network and then re-enable it and put in the new values. These tasks can take a significant amount of time (anywhere from 5 to 30 minutes} depending on how complex the network is and what is being changed. 

  • Add tag data.

    Note

    If you want to provision a VM to a specific Virtual Cluster, and your environment contains more than one port group on the same VLAN, use a separate network tag for each port group to avoid random selection of a port group when the VM is provisioned.

    In BMC Network Automation, if multiple port groups belong to the same VLAN, they are viewed as being the same network. However, in BMC Cloud Lifecycle management, the port groups represent two different networks. Therefore, you must tag the port groups individually, to avoid random selection of a port group.

  • Enable or disable associated networks, load balancers, and firewalls.

To make dynamic component selections in list view

These steps describe how to make selections when working in the list view. For guidelines on using the graphical view, see Working in the graphical view of dynamic components - create mode.

The following sections describe the tabs on the Dynamic Components dialog box.

Networks

These are the networks that are associated with the container blueprint selected in the General Information dialog box.

  1. Review the list of available networks, and determine which one or ones you want to enable for the container.

    Field

    Description

    Name

    The name of the network.

    Enabled

    Indicates whether the network is enabled or not.

    Tags

    Metadata that is applied to the network description.

    Zone

    The zone in which the network resides.

    Type

    String description that denotes the network type: for example, Customer, External, and so forth.

    Address

    The network address.

    Mask

    The network mask for the network address.

    Network Label

    The purpose of the network: for example, public, management, customer, data, application, and so forth.

  2. Click the Enable or Disable icon.
  3. To add tag metadata, click the Add Tag icon.

Load balancers

These are virtual load balancers associated with the networks specified under the Networks list.

  1. Review the list of available load balancers, and determine which one or ones you want to enable for the container.

    Field Description 

    Name

    The name of the load balancer.

    Client Networks

    Network from where traffic is coming into the load balancer pool.

    Server Networks

    Network to where traffic is going to from the load balancer pool.

    Enabled

    Indicates whether the load balancer is enabled or not.

  2. Click the Enable or Disable icon.

Back to top

Firewalls

The Firewalls tab is for the virtual, or perimeter, firewalls associated with the container.

  1. Review the list of available firewalls, and determine which one or ones you want to enable for the container.

    Field

    Description

    Name

    The name of the firewall.

    Enabled

    Indicates whether the firewall is enabled or not.

    IndependentIndicates that you can directly toggle the firewall, irrespective of the state of the serviced networks (enabled or disabled).
  2. Click the Enable or Disable icon.

Back to top

Distributed firewalls

These are distributed firewalls associated with the container. Enable or disable the associated distributed firewalls.

  1. Review the list of available distributed firewalls, and determine which one or ones you want to enable for the container.

    Field

    Description

    Name

    The name of the firewall.

    Enabled

    Indicates whether the distributed firewall is enabled or not.

    Independent

    Indicates that you can directly toggle the firewall, irrespective of the state of the serviced networks (enabled or disabled).

  2. Click the Enable or Disable icon.

    Note

    The container blueprint includes a distributed firewall which is attached to a particular switch and secures a certain set of networks. The distributed firewall virtual machine (VM) is created by BMC Network Automation when the network container is created (if the distributed firewall is enabled) or modified to enable a previous disabled distributed firewall.

Additional Parameters

  1. Click Next to continue to the Additional Parameters dialog box, where you can add runtime parameters from the network container blueprint. The parameters are name-value pairs.
  2. Click the Add Additional Parameters icon to add a row to the table.
  3. In the Name column, enter a parameter name that matches a network container blueprint parameter.
  4. In the Value column, enter a value for the parameter or select a value from the drop-down list that can be configured for the container.

    If there are parameters available in the network container blueprints, those parameters are pre-populated along with default values. You can modify values before submitting the create or modify container operations.



    Note

    Creating a network container from a previous version blueprint or modifying a network container created in a previous version do not support the pre-populated additional parameters. In these cases, you can add a parameter by clicking the Add button. 
  5. Click Submit.

To edit dynamic components of a network container

These steps describe how to edit selections when working in the list view. For guidelines on using the graphical view, see Working in the graphical view of dynamic components - edit and view modes.

  1. On the main Edit Network Container: Dynamic Components dialog box, select the desired tab and then select a network, load balancer, or distributed firewall to enable or disable. Then click the corresponding toggle button.

    You can enable or disable networks on the main Edit Network Container: Dynamic Components dialog box only, not from the secondary Edit Network Details dialog box. shown below.

  2. To add any new network tags, click the Add Tag icon on the Network tab.
  3. To edit the network address or subnet mask of a selected network, click the Edit Network icon to display the Edit Network Details dialog box.
  4. Update the network address and mask as needed.
  5. Click Save.
