Configuring VLANs

Aruba Central now supports a management 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. for the uplink traffic on an AP. You can configure an uplink VLAN when an AP needs to be managed from a non-native VLAN. After an AP is provisioned with the uplink management VLAN, all management traffic sent from the AP is tagged with the management VLAN.

To configure the AP management VLAN, complete the following steps:

1. In the Aruba Central app, select one of the following options:
   • To select a group in the filter:
     1. Set the filter to one of the options under Groups. Ensure that the group selected contains at least one active access point.
        The dashboard context for the group is displayed.
     2. Under Manage, click Devices > Access Points.
        A list of APs is displayed in the List view.
   • To select an AP in the filter:
     1. Set the filter to Global.
     2. Under Manage, click Devices > Access Points.
        A list of APs is displayed in the List view.
     3. Click an AP listed under Device Name.
        The dashboard context for the AP is displayed.
     4. Under Manage, click Device > Access Point.
2. Click the Config icon.
   The tabs to configure APs are displayed.
3. Click Show Advanced, and click the System tab.
   The System details page is displayed
4. Expand the VLAN accordion and specify the following parameters:

   • Customize VLANs of Uplink Ports—Configures the wired port profile on the uplink ports and allows to modify the VLAN settings. Select an option from the drop-down list.

   • Customize Management VLAN—Toggle the switch to customize the management VLAN.

     When Customize Management VLAN is enabled, downgrading the firmware to versions before ArubaOS 10.5.0.0 is not supported, especially in the case of static IP.

   • AP Management VLAN—Specify the AP management VLAN.

   • Obtain Management IP through 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. —Specify the AP management IP address through DHCP or Static IP through customized VLAN.

     By default, the Obtain Management IP through DHCP is enabled when you configure the management VLAN in a group context.

   • IP Address—Specify the AP management IP address.

   • Netmask—Specify the netmask.

   • Default Gateway—Specify the default gateway.

   • DNS Domain Name System. A DNS server functions as a phone book for the intranet and Internet users. It converts human-readable computer host names into IP addresses and IP addresses into host names. It stores several records for a domain name such as an address 'A' record, name server (NS), and mail exchanger (MX) records. The Address 'A' record is the most important record that is stored in a DNS server, because it provides the required IP address for a network peripheral or element. Servers—Specify the DNS servers.

   • Domain Suffix—Specify the domain suffix.

   The IP Address, Netmask, Default Gateway, DNS Servers, and Domain Suffix are available only when you configure the management VLAN in a device context.
