Add SSID Interfaces for Single Engines
You can define several SSID Interfaces for the Wireless Interface.
An SSID (service set identifier) interface represents an 802.11 wireless LAN. You can define several SSID Interfaces for the Wireless Interface.
For more details about the product and how to configure features, click Help or press F1.
Steps
SSID Interface Properties dialog box
Use this dialog box to configure properties for SSID interfaces.
Option | Definition |
---|---|
General tab | |
Wireless Network Name (SSID) | The name that identifies the network to the end users. |
Wireless SSID Broadcast |
Note: Even if you disable SSID broadcast, anyone within range can discover your wireless network with detection tools widely available on the Internet.
|
MAC Address Type |
|
MAC Address | (When MAC Address Type is Custom) Enter the custom MAC address. |
Zone
(Optional) |
Select the network zone to which the interface belongs. Click Select to select an element, or click New to create an element. |
Comment (Optional) |
A comment for your own reference. |

QoS Mode
(Optional) |
Select the QoS mode to apply to the link on this interface. You can select from one of the following options:
Note:
|
QoS Policy |
(When QoS Mode is Full QoS or DSCP Handling and Throttling) The QoS policy for the link on this interface. If the interface is a Physical Interface, the same QoS policy is automatically selected for any VLANs created under it. Note: If a Virtual Resource has a throughput limit defined, the interfaces on the Virtual Engine that use a QoS policy all use the same policy. The policy used in
the first interface is used for all the interfaces.
|
Interface Throughput Limit |
(When QoS Mode is Full QoS) Enter the throughput for the link on this interface as megabits per second. If the interface is a Physical Interface, the same throughput is automatically applied to any VLANs created under it. The throughput is for uplink speed (outgoing traffic) and typically must correspond to the speed of an Internet link (such as an ADSL line), or the combined speeds of several such links when connected to a single interface. CAUTION: Make sure that you set the interface speed correctly. When the bandwidth is set, the Engine always scales the total amount of traffic on this
interface to the bandwidth you defined. This scaling happens even if there are no bandwidth limits or guarantees defined for any traffic.
CAUTION: The throughput for a Physical Interface for a Virtual Engine must not be higher than the throughput for the Master Engine interface that hosts
the Virtual Engine. Contact the administrator of the Master Engine before changing this setting.

Security Mode |
|
Key Length | (When Security Mode is WEP Open System or WEP Shared Key) Select the encryption key length for WEP. |
Default Key | (When Security Mode is WEP Open System or WEP Shared Key) Select the encryption key to use by default for WEP. |
Key | (When Security Mode is WEP Open System or WEP Shared Key) Enter 1–4 decryption keys for WEP. By default, passwords and keys are not shown in plain text. To show the password or key, deselect the Hide option. |
WPA Mode | (When Security Mode is WPA Personal or WPA Enterprise) Select the encryption mode to use for WPA. |
Pre-Shared Key | (When Security Mode is WPA Personal) Enter the pre-shared key for WPA Personal. By default, passwords and keys are not shown in plain text. To show the password or key, deselect the Hide option. |
Authentication Method | (When Security Mode is WPA Enterprise) Click Select to select the authentication method for WPA Enterprise. |

Filter | Allows you to filter the elements shown. |
Up | Navigates up one level in the navigation hierarchy. Not available at the top level of the navigation hierarchy. |
A menu that contains various options, such as for creating new elements or showing elements that have been moved to the Trash. | |
Max Packet Size | Set the maximum allowed packet size. |
DHCP Relay | Select the CVI or IP address you want to use for DHCP relay. |
Trusted Circuit | When selected, DHCP relay agents that terminate switched or permanent circuits and can identify the remote host end of the circuit are allowed to add the Remote-ID option to the DHCP messages before relaying them. |

DHCPv4 tab, DHCPv4 Server settings (When DHCP Mode is DHCPv4 Server) |
|
DHCP Address range | Defines the DHCP address range that the Engine assigns to clients in one of the following ways:
Note: The DHCP address range must be in the same network space defined for the Physical
Interface. The DHCP address range must not contain the Engine's NDI or CVI addresses or broadcast IP addresses of networks behind the Engine.
|
Primary DNS Server | Enter the primary DNS server IP address that clients use to resolve domain names. If there is a listening IP address for DNS Relay on the same interface, clients use the DNS services provided by the engine by default. If you want clients to use a different external DNS server, enter the IP address of the external DNS server. |
Secondary DNS Server | Enter the secondary DNS server IP address that clients use to resolve domain names. |
Primary WINS Server | Enter the primary WINS server IP address that clients use to resolve NetBIOS computer names. |
Secondary WINS Server | Enter the secondary WINS server IP address that clients use to resolve NetBIOS computer names. |
Default Gateway | Enter the IP address through which traffic from clients is routed. |
Default Lease Time | Enter the time after which IP addresses assigned to clients must be renewed. |
Domain Name Search List
(Optional) |
Enter a comma-separated Domain Name Search List to configure DNS search suffixes. |
Override DHCP Ranges per Node
(Engine Clusters only) |
Enter the DHCP address range for each node. CAUTION: Enter unique ranges for each node. Overlapping ranges can cause IP address duplication.

Override Engine's Default Settings | When selected, the default settings of the Secure SD-WAN Engine are overridden. |
SYN Rate Limits |
|
Allowed SYNs per Second | Defines the number of allowed SYN packets per second. |
Burst Size | The number of allowed SYNs before the Engine starts limiting the SYN rate. We recommend that you set the burst size to be at least one tenth of the Allowed SYNs per Second value. If the burst size is too small, SYN rate limits do not work. For example, if the value for Allowed SYNs per Second is 10000, set the value for Burst Size to at least 1000. |
Enable Log Compression | By default, each generated Antispoofing and Discard log entry is logged separately and displayed as a separate entry in the Logs view. Log Compression settings allow you to define the maximum number of separately logged entries. When the defined limit is reached, a single antispoofing log entry or Discard log entry is logged. The single entry contains information about the total number of the generated Antispoofing log entries or Discard log entries. After this log entry, the logging returns to normal and all generated entries are once more logged and displayed separately. Log Compression is useful when the routing configuration generates a large volume of antispoofing logs or the number of Discard logs becomes high. For each event type, Antispoofing or Discard, you can define:
|
Set to Default | Returns all changes to the log compression settings to the default settings. |
Send IPv6 Router Advertisements | Select and specify what configuration information is offered in the Router Advertisement messages to devices that connect to the same network as the engine. |
Managed address configuration | When selected, the router advertisement messages that the Engine sends instruct the hosts to use the DHCPv6 protocol to acquire IP addresses and other configuration information. |
Other configuration | When selected, the router advertisement messages that the Engine sends instruct the hosts to acquire the IPv6 prefix and the default route information from the router advertisement messages, and to use the DHCPv6 protocol to acquire other configuration information (such as DNS server addresses). |
