About the Networks page


To work with networks and network aliases, you use the Networks page in the HCP System Management Console.

The Networks page has four sections:

Network View — Lets you view, create, modify, and delete networks and network aliases, and monitor the health of individual networks.

Node View — Lets you view, add, modify, and delete the IP addresses assigned to each node for each network.

NoteWebHelp.png

Note: Both the Network View panel and the Node View panel let you view and modify node IP addresses. However, the Network View panel shows the node IP addresses defined for each network, while the Node View panel shows the IP addresses assigned to each node for all networks in which it participates. The Node View panel is particularly useful for assigning IP addresses to nodes that are added to the HCP system after you’ve defined multiple networks.

All Zone Definitions — Lets you view the DNS zone definitions that HCP uses for all network domains that are currently defined on the HCP system.

NoteWebHelp.png

Note: You cannot filter the list of DNS zone definitions that are displayed on the All Zone Definitions panel. However, you can use the Network View panel to display all properties of any specific network, including the zone definition information for that network.

For information on displaying zone definition information for a specific network or for all networks defined on the system, see Viewing the DNS zone definition for a network domain.

Advanced Settings — Lets you enable IP address configurations for the nodes in your networks and enable virtual network management.

To display the Networks page, in the top-level menu, select Configuration Networks.

The System Management Console opens the Networks Network View page.

RoleWebHelp.png

Roles: To view the Networks page, you need the monitor, administrator or service role. To create, modify, and delete user-defined networks and network aliases, you need the administrator role. To modify the [hcp_system] or [hcp_backend] network, you need the service role.

When you use the Configuration menu to access the Networks page, the Networks Network View is displayed by default. You can then use the tabs on the left side of the page to navigate between sections.

About the Network View page


The Networks Network View page lets you view, create, modify, and delete networks and network aliases, and monitor the health of individual networks. This panel displays a list of existing networks and network aliases defined for the HCP system and shows basic configuration information and alerts for each network and network alias.

Understanding the network list


The NetworksNetwork View contains a list of existing networks and network aliases. For each network, this list shows:

The network name.

The IP mode currently used for the network. The IP mode for a network indicates the types of IP addresses that the network is configured to use for each node that participates in the network.

If the IP mode for a network is:

oIPv4, the network is configured to use only IPv4 addresses

oIPv6, the network is configured to use only IPv6 addresses

oIPv4/IPv6, the network is configured to use both IPv4 and IPv6 addresses

All IPv4 and IPv6 subnets that are defined for the network, shown in CIDR format.

The name of the network domain.

None, one, or more alert icons representing problems with the network. To see the text that accompanies an icon, hover over the icon.

For information on the alerts that can appear on the Networks Network View page, see Networks page alerts.

For each network alias, the list shows:

The alias name

The IP mode, IPv4 and IPv6 subnets, and domain name used for the target network

The alerts that apply to the target network

Additionally, the network list displays this icon in the table row that corresponds to the network or alias that’s currently selected as the replication network: ReplicationNetwork.png

To view more information about a specific network or network alias, or to modify the configuration settings used for that network or network alias, click on its name in the network list.

To filter the list by network name:

1.Select Name from the drop-down list above the network list.

2.In the text field, type the text string that you want to use as a filter. This string can be up to 64 characters long, can contain any valid UTF-8 characters except commas (,), and is not case sensitive. White space is allowed.

3.Click on the find control ( FindControl.png ).

When filtered by network IP mode, the list includes only those networks and network aliases that have the specified IP mode (IPv4, IPv6, or IPv4/IPv6).

To filter the list by IP mode:

1.Select IP Mode from the drop-down list above the network list.

2.In the text field, type the text string that corresponds to the IP mode that you want to use as a filter:

oType IPv4 to filter the list to show the networks and network aliases that are configured to use only IPv4 addresses.

oType IPv6 to filter the list to show the networks and network aliases that are configured to use only IPv6 addresses.

oType IPv4/IPv6 to filter the list to show the networks and network aliases that are configured to use both IPv4 and IPv6 addresses.

3.Click on the find control ( FindControl.png ).

About the Advanced Setting panel


The Networks Advanced Settings page is used for enabling network creation, configuring network versions for your nodes, and enabling the management network if the system is configured for the management network.

Enabling IPv4 and IPv6 addresses

IPv4 addresses are automatically permitted on all nodes in your networks. To permit IPv6 addresses on all nodes in your networks, on the Networks Advanced Settings page, select Enable IPv6.

Enabling and configuring the management network

Allowing management network configuration lets users with the system administrator role to segregate system management traffic to the [hcp_management] network. For more information on the management network, see HCP networks.To enable and configure the management network:

1.On the Networks Advanced Settings page, select Allow Management Network Configuration. This option is visible only if HCP is running on either hardware or VM that is configured for the management port network.

NoteWebHelp.png

Note: If the Allow Management Network Configuration is visible but grayed out on the Advanced Settings page, it means that [hcp_management] network is enabled. If you want to disable Allow Management Network Configuration, you first need to set the [hcp_management] Network status to disable. For more information on disabling the Network status, see Modifying a network on the Network View panel.

2.Click on Update Settings.

3.On the Networks Network View page, confirm that the [hcp_management] network is listed.

4.Click on the [hcp_management] network, then click on the IP Configuration tab.
