Configuring System IP Address for an AOS-10 Branch Gateway

Each AOS-10 Branch Gateway requires a unique system IP address that is used by the gateway to communicate with network services such as VPN Virtual Private Network. VPN enables secure access to a corporate network when located remotely. It enables a computer to send and receive data across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security, and management policies of the private network. This is done by establishing a virtual point-to-point connection through the use of dedicated connections, encryption, or a combination of the two., RADIUS Remote Authentication Dial-In User Service. An Industry-standard network access protocol for remote authentication. It allows authentication, authorization, and accounting of remote users who want to access network resources. , Syslog, TACACS+ Terminal Access Controller Access Control System+. TACACS+ provides separate authentication, authorization, and accounting services. It is derived from, but not backward compatible with, TACACS.  and SNMP Simple Network Management Protocol. SNMP is a TCP/IP standard protocol for managing devices on IP networks. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, and more. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. . The system IP addresses for your gateways can be assigned from the group using a pool or a per device or a bulk configuration upload.

To configure a system IP for an AOS-10Branch Gateway, complete the following steps:

1. In the WebUI, set the filter to a group that contains at least one Branch Gateway.
   The group dashboard is displayed.

2. Under Manage, click Devices > Gateways.
   A list of gateways is displayed in the List view.
   

3. Click a gateway under Device Name.
   The gateway device dashboard is displayed.
   

4. Under Manage, click Device.
   The gateway configuration page is displayed.
   If you are accessing the Branch Gateway configuration page for the first time, the Guided Setup wizard opens automatically. Otherwise, click the Guided Setup.
   

5. In the System tab, select one of the following methods to configure the system IP:

   • If you have not configured a system IP address pool during the group or the device configuration, complete the following steps in Configuration approach:

     • Define system IP address—If you select this option, enter the system IP address in the IPv4 Address field and enter a value in the Netmask field.
     • Specify static IP addresses later—Select this option if you want to define the system IP address at a later stage.
   • These options will appear only when you are on-boarding the device for the first time.
   • The administrator must configure system IP address for the HPE Aruba Networking Gateway to become completely operational.

   • If you have configured the system IP address pool for VLAN Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. 4087, which is the reserved system VLAN and a Controller IP VLAN, then the VLAN Interface is a read-only field that displays VLAN 4087.

   • If you have defined a system IP address pool during group configuration or in the Loopback Interface during device configuration, complete the following step:

     • VLAN Interface—Select the VLAN interface from the drop-down list to assign an IP address to the Branch Gateway.

6. If you have not configured a system IP address pool during the group or the device configuration, complete the following steps in Configuration approach:

   • Define system IP address—If you select this option, enter the system IP address in the IPv4 Address field and enter a value in the Netmask field.
   • Specify static IP addresses later—Select this option if you want to define the system IP address at a later stage.
• These options will appear only when you are on-boarding the device for the first time.
• The administrator must configure system IP address for the HPE Aruba Networking Gateway to become completely operational.

7. If you have configured the system IP address pool for VLAN 4087, which is the reserved system VLAN and a Controller IP VLAN, then the VLAN Interface is a read-only field that displays VLAN 4087.

8. If you have defined a system IP address pool during group configuration or in the Loopback Interface during device configuration, complete the following step:

   • VLAN Interface—Select the VLAN interface from the drop-down list to assign an IP address to the Branch Gateway.

9. Click Next.

   The Hostname page is displayed.

10. Enter the Hostname and click Next.
11. Review the Summary page and click Finish.

    The Finish button is disabled if there are any errors in the configuration. Resolve the errors to proceed to the next step.

12. Click Continue to configure a LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. interface.
