Configuring the WAN Uplink

Uplinks connect Microbranch to underlay networks. By default, both wired and cellular uplinks are set as active links with load balancing enabled on Microbranch.

To configure a WAN Wide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. interface, complete the following steps:

1. In the Aruba Central app, set the filter to a Microbranch group that contains at least one AP.

   The dashboard context for a group is displayed.

2. Under Manage, click Devices > Access Points.

3. Click the Config icon.

   The Microbranch group configuration page is displayed.

4. In the WAN card, click WAN Uplink.

   The WAN uplink page is displayed. This section defines uplink interfaces by creating WAN-facing VLANs 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., labeling them as uplink interfaces, and assigning them to the desired uplink ports.

5. To add a WAN port, click the + icon in the WAN Uplinks table.

   The Add Uplink page is displayed.

6. To configure an ethernet or cellular uplink, select the WAN type from the drop-down list, and enter details for the parameters provided in the following table.

   Table 1: WAN Parameters

   Parameters	Description
   Uplink	Specify the name of the uplink.
   VLAN	Specify the VLAN ID that you want to assign to the uplink. By default, this is set to 4092 or 4093 based on availability. NOTE: The valid VLAN IDs range from 2 to 4093, except 3333.
   WAN Type	Specify one of the following connection types: Ethernet Ethernet is a network protocol for data transmission over LAN. Cellular By default, Ethernet is selected. NOTE: Aruba Central creates a wired profile when ethernet uplink (eth0 or eth1) is added as one of the uplink profile. For more information of wired profiles, refer Configuring Port Profiles.
   If WAN Type is Ethernet, provide details for the following parameters.
   Speed	Configure the uplink speed to optimize performance. Range of values is 10-5000 Mbps. If not set, the WAN uplink speed defaults to auto-negotiated port speed for INET, MPLS Multiprotocol Label Switching. The MPLS protocol speeds up and shapes network traffic flows. , and Metro-Ethernet. Based on the speed and bandwidth threshold allowed for an uplink, Microbranch assigns the session traffic.
   Use as backup	Enable this option if you want to use the uplink in the standby mode. By default, only one uplink operates as an active uplink. While configuring the first uplink, this option is disabled. While configuring the second uplink, this option is enabled. NOTE: This option is disabled while editing the existing uplink configuration.
   IP addressing method	Select one of the following options: DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  server assigned—Select this option to assign an IP address from a DHCP pool to the WAN uplink. Static IP address—Select this option to manually configure an IP address on the WAN interface.   NOTE: The static IP address uplink requires a default gateway, which can be configured in the Static Routing section. For more information, see Configuring Static Routing. The Static IP address option is available only for device-level configuration. PPPoE Point-to-Point Protocol over Ethernet. PPPoE is a method of connecting to the Internet, typically used with DSL services, where the client connects to the DSL modem.—Select this option to select an authentication type to connect to the ISP Internet Service Provider. An ISP is an organization that provides services for accessing and using the Internet.. NOTE: You can configure PPPoE at the group or device level.
   Static IP address	Enter the static IP address. This option is available only if the IP addressing method is Static IP address.
   Network mask	Enter the network mask. This option is available only if the IP addressing method is Static IP address.
   User	Enter the username. This option is available only if the IP addressing method is PPPoE.
   Password and Retype Password	Enter the password, and retype the password. This option is available only if the IP addressing method is PPPoE.
   CHAP Challenge-Handshake Authentication Protocol. CHAP is a challenge and response authentication method used to verify the identity of a remote user. Secret and Retype CHAP Secret	Enter the CHAP secret, and retype the CHAP secret. This option is available only if the IP addressing method is PPPoE.
   Service Name	Enter the PPPoE service name. This option is available only if the IP addressing method is PPPoE.
   LCP interval	Enter the PPPoE LCP interval. This option is available only if the IP addressing method is PPPoE.
   LCP failure	Enter the PPPoE LCP failure value. This option is available only if the IP addressing method is PPPoE.
   Port assignment	Assign an available port for the uplink. For ethernet, maximum of two ports can be assigned. The previously assigned ports are not available for selection in the drop-down list.
   If WAN Type is Cellular, provide details for the following parameters to configure Cellular WAN Type (3G Third Generation of Wireless Mobile Telecommunications Technology. See W-CDMA. or 4G Fourth Generation of Wireless Mobile Telecommunications Technology. See LTE. uplinks).
   Type	Select Aruba USB Universal Serial Bus. USB is a connection standard that offers a common interface for communication between the external devices and a computer. USB is the most common port used in the client devices.  LTE Long Term Evolution. LTE is a 4G wireless communication standard that provides high-speed wireless communication for mobile phones and data terminals. See 4G. as the modem type to configure a 3G or 4G uplink manually.
   Access Point Name (APN)	Enter the name of the Access Point to which the uplink connects.
   Public land Mobile Network (PLMN Public Land Mobile Network. PLMS is a network established and operated by an administration or by a Recognized Operating Agency for the specific purpose of providing land mobile telecommunications services to the public.)	Select Auto or Manual for the PLMN. If you have selected Manual, enter the PLMN ID in the text box. By default, Auto is selected.
   Mode	Select one of the following network modes: Auto —This mode keeps both 3G and 4G LTE options open and switches based on availability. 4G LTE—Connects to the 4G LTE cellular network and takes the default frequency band Band refers to a specified range of frequencies of electromagnetic radiation.. 3G—Connects to the 3G cellular network and takes the default frequency band.
   Enable GPS Global Positioning System. A satellite-based global navigation system.	Select the check box to enable GPS.
   Sim Slot	Select sim slot 1, 2, or Auto. By default, Auto is selected.
