Configuring Advanced Network Settings

Advanced Network Settings include additional options for configuring the network.

After selecting other network options, this is an optional section before the network is actually created. Not all options appear for all types of network. Exceptions are highlighted. Configure the following advanced network settings:

  1. In VLAN ID: Type the VLAN ID number (default is 1) that you want to assign to this network.
  2. In Max. Number of Devices: (Only for Captive Portal Host Approval and Self Sign In networks) Select the maximum number of devices that can connect to the network.
    The list allows up to 10 devices.
  3. In User Connection Settings (Default): (Only for Captive Portal networks except Click-Through)
    • Allow the user to stay connected for: Select Minutes or Hours from the drop-down arrow box and then use the up/down arrows to select the number of minutes or hours of connection time after which the client is disconnected.
    • Do not redirect to the portal when reconnecting within: You can set the grace period which sets the number of minutes during which previously authenticated clients that disconnect from the network can rejoin the network without going through the authentication process again. The default grace period is 60 minutes, but this time cannot be longer than the allowed user connection period.
  4. In User Connection Settings (Time Limited): (Only for Captive Portal Click-Through networks) If you have clicked the Change to Time limited connection option.
    • Allow users to connect for: Enter an aggregated time period after which the user is disconnected. The default is 24 hours.
    • After that time, don't allow to reconnect for: Sets a lock-out time during which users are not allowed to sign-in again. The default is 2 hours.
  5. In the Load Control section:
    • Max rate: There are three options:
      • Unlimited—no limits on bandwidth allocation.
      • Per AP—The maximum bandwidth allocation limit of all connections to that specific network on the AP. If selected, two other options appear, Upload Limit and Download Limit. If either (or both) check boxes are selected, a sliding scale appears and you can drag your cursor along the line to choose the Mbps limits.
      • Per Client—The maximum bandwidth allocated for a device connected to this network. If selected, two other options appear, Upload Limit and Download Limit. If either (or both) check boxes are selected, a sliding scale appears against each option and you can drag your cursor along the line to choose the Mbps limits.
    • Max clients per radio: Limit the number of clients that can associate with this network per AP radio (default is 100).
    • Enable load balancing between 2.4GHz & 5GHz radios: Select this check box to enable load balancing between the 2.4GHz and 5GHz radios. Load balancing helps improve network performance by helping to spread the client load between the two radios on the AP.
    • Enable load balancing between APs: Select this check box to spread the client load between nearby access points, so that one AP does not get overloaded while another sits idle.
  6. In Access Control section: you can define a user traffic policy by clicking the Set up a Policy link. The Traffic Control Policy dialog appears.
    By default, the Allow Traffic option (green) is enabled. You can choose to change this to Deny Traffic by clicking the option (red) provided.
  7. To create a new traffic rule, click the Add Rule link. The Add Traffic Access Rule dialog appears. You can create rules only for up-stream traffic.
    Note: L3/L4 traffic policy rules will not be applied to traffic between clients attached to the same WLAN on the same AP.
    • Enter a description for the rule in the text field provided.
    • You can create a rule to allow or block up-stream traffic by clicking and selecting the Allow Traffic or Block Traffic option, respectively.
    • Select the protocol which you wish to use for the new traffic rule, from the Protocol drop down list. Following are the list of protocols available for use.
      • TCP—Transmission Control Protocol
      • UDP—User Datagram Protocol
      • UDPLITE—Lightweight User Datagram Protocol, which is a connectionless protocol that allows even a damaged data payload to be delivered rather than being discarded.
      • ICMP (ICMPV4)—Internet Control Message Protocol, which is an error-reporting protocol used by network devices to generate error messages to the source IP address, when issues in the network prevent delivery of IP packets.
      • IGMP—Internet Group Management Protocol, which is a communications protocol used by hosts on IPv4 networks to establish multicast group memberships.
      • ESP—Encapsulating Security Payload is a protocol which provides the authentication, integrity, and confidentially of network packets in IPv4 and IPv6 networks.
      • AH—Authentication Header protocol, which is used to authenticate SNMP.
      • SCTP—Stream Control Transmission Protocol is a communications protocol which operates at the transport layer.
    • Specify the source address in the Source field. You can either specify a range (a network address and a Subnet Mask, in the field provided) or you an specify a source IP address in the field provided. Also, specify a port number or a range of ports (e.g: 22-34) for the source, in the field provided.
    • Specify the destination address in the Destination field. You can either specify a range (a network address and a Subnet Mask, in the field provided) or you an specify a source IP address in the field provided. Also, specify a port number or a range of ports (e.g: 22-34) for the destination, in the field provided.
      Note: If you choose the ICMP protocol in the previous step, you do not need to specify ports for the source and the destination. Hence, the option to select ports will not be presented to you.
  8. Click Create. The rule which you created appears in the Traffic Control Policy dialog.
    Note: The rule which you initially create appears in a row with priority set a "1", by default. When you create a second rule, it appears in the row with priority "1" and the previous rule which you created appears as second in the row, with priority "2". When you have multiple rules created, you can use the "up" and "down" arrows available at the end of each row, to shift respective rows up or down in the order, to set the desired priority.

    The edit and delete links available at the end of each row allow you to edit and delete respective rules. Each time you click the edit button, the Add Traffic Access Rule dialog appears where you can edit any of the rule properties.

  9. Click OK in the Traffic Control Policy dialog, once you have all the required rules added.
    You are navigated back to the Advanced Network Settings dialog, where are can click the Traffic Policy toggle button to "ON" or "OFF", activating or de-activating the traffic policy which you created, respectively. The Edit option allows you to navigate to the Traffic Control Policy dialog, where you can edit the policy which you created. The Clear button allows you to delete the traffic policy.
  10. In Enable Client Isolation: Select this check box to prevent clients on the same network from communicating with each other.
  11. In Force DHCP: Select this check box to force clients to obtain a valid IP address from a DHCP server. This prevents clients configured with a static IP address from connecting to the network.
    If a client performs Layer 3 roaming between different subnets, in some cases the client sticks to the former IP address. This mechanism optimizes the roaming experience by forcing clients to request a new IP address.
  12. In Hide SSID: Select this check box if you do not want the ID of this network advertised at any time. This will not affect performance or force the network user to perform any unnecessary tasks.
  13. In Enable OFDM only (Disables 802.11b): Enabling this option disables CCK rates of 1, 2, 5.5, and 11 Mbps, so no 802.11b-only clients can connect. Beacons and probe responses will be transmitted at 6 Mbps, and data frames at 6, 9, 18, 24, 36, 48, and 54 Mbps. Enforcing higher minimum data rates increases overall network throughput capacity, but reduces the distance at which clients are able to remain connected.
  14. In Enable logging client data to external syslog: Select this check box to allow client data to be logged in all venues that have the external syslog server enabled. The box is unchecked by default. Refer to the page for details about configuring the external syslog server for a venue.
  15. In BSS Min Rate: Use this option to configure the minimum transmission rate supported by the network. If OFDM Only is enabled, the only valid options are 12 Mbps and 24 Mbps, with Mgmt Tx frames fixed at 6 Mbps. This option can also be used to prevent 11b clients from connecting, and to allow greater client density with higher data rates.
  16. In Mgt Tx Rate: This option is only available if both OFDM Only and BSS Min Rate are disabled. (Otherwise, the Mgmt Tx Rate is defined by those settings.) Use this setting to configure the rate at which management frames are sent. The default is 6 Mbps.
  17. Click Reset to Defaults in the lower left side of the screen to reset all the advanced settings back to their defaults.
  18. Click OK to save your settings.
You have completed configuring the advanced network settings.
