Configuring Uplink Interfaces on a 9004-LTE Branch Gateway

  1. To configure a Branch Gateway group or a Branch Gateway, complete one of the following steps:

    • To select a gateway group:

      1. In the HPE Aruba Networking Central app, set the filter to a group that contains at least one Branch Gateway.

        The dashboard context for a group is displayed.

      2. Under Manage, click Devices > Gateways.

        A list of gateways is displayed in the List view.

      3. Click Config.

        The configuration page is displayed for the selected group.

    • To select a gateway:

      1. In the HPE Aruba Networking Central app, set the filter to Global or a group that contains at least one Branch Gateway.

      2. Under Manage, click Devices > Gateways.

        A list of gateways is displayed in the List view.

      3. Click a gateway under Device Name.

        The dashboard context for the gateway is displayed.

      4. Under Manage, click Device.

        The gateway device configuration page is displayed.

  2. If you are in the Basic Mode, click Advanced Mode to access the advanced configuration options.

  3. Go to WAN > Uplink. The Uplink configuration page opens.

  4. To add an uplink, click + in the Uplink VLANs table and select LTE from the Link type drop-down list.

    5. For detailed information, see Configuring an LTE Uplink.

    The following table contains the new fields that need to be configured for 9004-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. Gateway along with the existing fields:

    Table 1: Configuring an LTE Uplink on a 9004-LTE Gateway

    Parameter

    Description

    Link Name

    Specify the name of the uplink.

    Connection type

    Specify one of the following connection types:

    NOTE: For a 9004-LTE Branch Gateway, the default connection type is Internal.

    Interface VLAN ID

    The 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. ID assignment is not configurable for 4G Fourth Generation of Wireless Mobile Telecommunications Technology. See LTE. LTE USB and Internal uplinks. By default, VLAN ID 4095 is assigned to the 4G LTE USB and Internal uplinks.

    Low frequency probe

    This is a global configuration for all LTE connections. Use this check box to enable less-frequent health check probing on the LTE uplink. LTE uplinks normally have lower bandwidth compared to wired uplinks, therefore you may want to enable less frequent probing on the LTE uplinks. When Low frequency probe is enabled, health check probes are sent every 15 seconds with a burst size of 2 packets for all LTE uplink interfaces configured on the Branch Gateway.

    Use only as backup link

    By default, all uplinks operate as active uplinks. If you want to use the uplink in the standby mode, select this check box.

    Bandwidth Percentage

    Use this field to configure bandwidth percentage for uplink utilization. This field is available only for the Uplink utilization load balancing mode.

    Speed

    You can configure a custom value for uplink speed to optimize performance. The allowed range of values is 1–10000 Mbps. If not set, the WAN Wide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. uplink speed defaults to 100 Mbps for LTE. Based on the speed and bandwidth threshold allowed for an uplink, Branch Gateways assign session traffic.

    Weight

    For Round Robin and Session Count load balancing modes, you can define a value for Weight within a range of 1–100. By default, this is set to 10. In an active-active uplink scenario, an uplink with a higher weight is assigned more session traffic than an uplink with a lower weight.

    If you have selected Internal as the Connection Type, enter details for the following parameters:

    Active SIM slot

    Select SIM Subscriber Identity Module. SIM is an integrated circuit that is intended to securely store the International Mobile Subscriber Identity (IMSI) number and its related key, which are used for identifying and authenticating subscribers on mobile telephony devices. 1 or SIM 2 as the active uplink.

    Access point name (APN)

    Enter the name of the Access Point to which the uplink connects.

    Public land mobile network (PLMN)

    A 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. ID is a six digit ID which is a combination of Mobile Country Code and Mobile Network Code. Each service provider has their own PLMN code. This field allows you to restrict roaming. Select Auto or Manual for the PLMN mode. If you have selected Manual, enter the PLMN ID in the text box. By default, PLMN is on Auto mode.

    Mode

    Select one of the following network modes:

    • Auto—This mode keeps both 3G Third Generation of Wireless Mobile Telecommunications Technology. See W-CDMA. 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.
    • Custom—If you want to select one of the supported frequency bands for 3G and 4G LTE, select Custom. The following fields are displayed:
      • 3g band selection—Select the desired 3G band from the drop-down list.
      • 4g LTE band selection—Select the desired 4G LTE band from the drop-down list.

      • NOTE: The frequency bands are specific to the internal modem and not the SIM. You will experience an interim disruption in the cellular connectivity when a frequency band is configured. The connection is established only if the frequency band is supported in your region.

    Data Usage Tracking

    Turn on the toggle switch to start tracking your data usage. If this field is enabled, the options to configure data usage limit and the Billing cycle are displayed.

    Data usage alert limit

    Enter the data limit in megabytes (Range – 1 to 65535 MB) to be used per month. Configure an alert in the Alerts & Events page for the alert to be generated when the data usage crosses the specified limit.

    Monthly Billing start date

    Select the day of the month on which the billing cycle begins.

  5. Click Save Settings.
