Provide Client Network Configuration Information

Language:

Ideally, the client network should be on a separate subnet from the management network, but they can be on the same subnet, if necessary.

In the Network Settings pane, click the Client Network tab.
The configuration fields for the client access network is displayed.
Click on the Configure IP Allocation button.
The Configure IP Allocation window appears.
Enter the starting IP address for the client access network and the IP address pool size.
Information that you enter into this tool will assign IP addresses for the client access network. The first twelve IP addresses will be assigned to components at the system level (for example, for the two compute nodes and the kernel zone), and the remaining IP addresses will be used for the database and application virtual machines that you create later on.
- Starting IP address — The starting IP address for the IP addresses assigned to the client access network.
- IP Address Pool Size — The total number of IP addresses that you need for the client access network. Beginning with the starting IP address you entered above, this number represents the number of consecutive IP addresses that will be available for the system-level components, such as compute nodes, and the client access network when creating database or application virtual machines and groups.
  
  You need at least twelve IP addresses for the client access network for the system-level components. The additional number of IP addresses that you need for virtual machines and groups varies, depending on the number of virtual machines and groups you create. However, the maximum number of IP addresses that you need for virtual machines and groups is typically around 45.
Click the Add button.
The starting IP and IP address pool size information is populated into the table on this page.
Add additional IP addresses for the client access network, if necessary.
You can add additional sets of IP addresses for the client access network by entering additional starting IP addresses and IP pool size information in those fields, and clicking the Add button for each set. Each set of new starting IP addresses and IP address pool size is populated into the table each time, as shown here.

Note - All IP addresses on the client network must be from the same IP subnet. Multiple subnets on the same client network are not supported.

Tip - Consecutive IP addresses are assigned for each range that you enter into the Configure IP Allocation window, starting with the entry that you put into the Starting IP Address field for that range. However, if you need to have individual, non-consecutive IP addresses for the client access network, enter each IP address in the Starting IP Address field, and enter 1 in the IP Address Pool Size, then click the Add button. Repeat this process to configure multiple non-consecutive IP addresses for the client access network.
Verify that the information that you entered in the Configure IP Allocation window is correct.
To delete a set of IP addresses from the list, select that set of address and click Delete.

You can access this window again from the main Initial Configuration tool window. However, once you have completed the Initial Configuration tool process and you have generated the IP addresses, the only way to change the IP address pool information is to completely rerun these procedures again.

Note - Even though this IP address pool information will be set once you complete the Initial Configuration tool process, you can add additional IP addresses to the client access network IP address pool using the MiniCluster BUI. Refer to the Oracle MiniCluster S7-2 Administration Guide for more information.

When you finish entering the information in the Configure IP Allocation window, click OK.
The Configure IP Allocation window disappears, and the IP address information is populated with the information that you entered in the Configure IP Allocation window.

If you provided information for more than one set of IP addresses in the Configure IP Allocation window, then the IP address information will reflect everything that you entered in the Configure IP Allocation window. For example, if you entered information for two sets of IP addresses, and entered 25 for the IP pool size for each of those two sets of IP addresses, you would see 50 in the IP Pool Size field.

You can click the Configure IP Allocation button again to view or edit the IP addresses that you entered for the client access network.
Enter the gateway IP address for the client access network in the Gateway IP Address field.
Enter the subnet mask for the client network in the CIDR Prefix field.
For example, 23. See Step 4 in Provide Management Network Configuration Information for the table to find the CIDR equivalent of your subnet mask. Ideally, the client network should be on a separate subnet from the management network, but they can be on the same subnet, if necessary.
Enter the IP addresses for the client domain name servers in the DNS Server 1, 2, and 3 fields.
At least one IP address must be provided, starting with the DNS Server 1 field. The entries for the DNS servers can be the same, or they can be different, from the entries for the DNS servers that you provided in the Management Network tab.
Enter the IP addresses for the client Network Time Protocol servers in the NTP Server 1 and 2 fields.
At least one IP address must be provided, starting with the NTP Server 1 field. The entries for the NTP servers can be the same, or they can be different, from the entries for the NTP servers that you provided in the Management Network tab.

Note - If you find that you need to change the client DNS or NTP server entries at any time after the initial installation is complete, you can make those changes through the MCMU BUI. Refer to the Oracle MiniCluster S7-2 Administration Guide for those instructions. Note that you cannot change the management DNS or NTP server entries after the initial installation without a system reset.
In the Network Redundancy Type field, determine the method that you want to use to make the client access network highly available.
Options are IPMP (IP network multipathing) or LACP (link aggregation control protocol).

Note - Do not choose LACP unless you are certain that your switch is properly configured to support LACP.

If you select LACP, complete the following fields:
- Load Balancing Policy — The load balancing policy. Options are L4, L2, or L3.
- Configured LACP Mode — The configured LACP mode. Options are:
  - Active — Enables LACP unconditionally.
  - Passive — Enables LACP only when an LACP device is detected.
Determine if you want to set up a VLAN configuration on the client access network.
- If you do not want to set up a VLAN configuration on the client access network, leave the two VLAN fields blank. Go to Step 14.
- If you want to set up a VLAN configuration on the client access network, determine if you want to set up a tagged VLAN configuration or an untagged (port-based) VLAN configuration.
  
  Note - Do not choose a VLAN configuration unless you are certain that your switch is properly configured to support VLANs.
  - VLAN ID — If you want to set up a tagged VLAN configuration on the client access network, enter the VLAN tag ID.
  - Port VLAN ID — If you want to set up an untagged (port-based) VLAN configuration, enter the port VLAN ID.

In the Client Connectivity field, select the method that you will use to connect the MiniCluster to the 10GbE client access network.
Options are:
- Copper — Choose this option if you are connecting to the client access network through the NET 2 and NET 3 ports, using Category 6/6E (RJ45) Ethernet cabling.
- Fiber — Choose this option if you are connecting to the client access network through the 10GbE NIC, using either of the these two cables:
  - QSFP to 4x SFP copper splitter cable
  - MPO to 4x LC duplex fiber optic splitter cable
See Connect the 10GbE Client Access Network for more information.
