Configuring VLAN Settings for WLAN SSID Profile in Tunnel and Mixed Mode

To configure VLANVirtual 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. settings for an SSIDService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network., complete the following steps:

  1. To access the WLANWireless Local Area Network. WLAN is a 802.11 standards-based LAN that the users access through a wireless connection. SSID configuration wizard for a new SSID profile or an existing SSID profile, see Configuring a WLAN SSID Profile in Bridge Mode or Creating a WLAN Profile in Tunnel and Mixed Mode.
  2. In the WLAN SSID configuration wizard, click the VLANs tab.
  3. In the VLAN tab, select any of the following options in Traffic Forwarding Mode to create a network in tunnel mode:
    • Tunnel—To forward client traffic to an Aruba gateway node in the tunnel mode network, select the Tunnel mode.
    • Mixed—To use both bridge and tunnel forwarding modes, select the Mixed option. To enable APs to tunnel client traffic to a gateway node in the tunnel mode network, select a gateway cluster from the Cluster drop-down list.
  4. Select one of the following options from the Primary Gateway Cluster drop-down list:
    • For auto-group clusters, select <group name:auto_gwcluster_<group ID>_0>. For example, Group1:auto_gwcluster_243_0.
    • For auto-site clusters, select <group name:auto_gwcluster_site_<site ID>_<group ID>_0>. For example, Group1:auto_gwcluster_site_8_243_0.
    • For manual clusters, select <groupname:manualclusterprofilename>. For example, Group2:ManualCluster123.

    The Primary Gateway Cluster drop-down list allows the APs to establish tunnels with the gateways in the tunnel mode network.

  5. (Optional), select a secondary gateway cluster profile from the Secondary Gateway Cluster drop-down list.

     You can use the Secondary Gateway Cluster drop-down list as a failover, when the primary cluster is unavailable.

    • Select the Cluster Preemption check box to allow the AP to switch back from the SSID of secondary gateway cluster to the SSID of primary gateway cluster, when the primary gateway cluster becomes available.
  6. Select the client VLAN assignment mode for WLAN clients and configure the following parameters:
  7. Click the Show VLAN section to view all the named VLANs mapped to the VLAN ID.
  8. To configure the VLAN Name and VLAN ID mapping feature, click the Add Named VLAN option to enter the VLAN Name and VLAN ID that is required to be mapped.
  9. Click Next to configure security settings.

Important Points to Note

  • When you select <group name:auto_gwcluster_site_<site ID>_<group ID>_0> from the Primary Gateway Cluster drop-down list, the tunnel orchestrator service automatically allows the devices on the particular site to establish tunnels among themselves. For example, an AP in site S1 only establishes tunnel with a gateway in site S1. The AP in S1 does not establish a tunnel with the gateway in site S2.
  • The following are the various scenarios applicable when you select the Cluster Preemption check box:

    • The reachable number of gateways in the primary cluster is equal to or more than the secondary cluster.
    • When all the tunnels are down, the tunnel that comes up first will serve the SSID profile.
    • The virtual APs wait for 5 minutes after they failover from one gateway cluster to another.
    • There is 1 minute delete time for Virtual APs when they failover from primary cluster to secondary cluster and vice versa.
    • All clients get disconnected during failover from one cluster to another.
