Use this dialog box to define the Layer 3 Physical Interface properties for a Master Engine in the Engine/VPN role or a Virtual Engine.

General tab | |
Interface ID | The Interface ID automatically maps to a physical network port of the same number during the initial configuration of the engine. The mapping can be changed as necessary
through the engine’s command line interface. Note: Changes to the Master Engine interface mapping do not affect the Interface IDs that are defined for Virtual Engines
in Virtual Resource elements.
|
Type |
Note: We recommend that you do not use the IP address of an Aggregated Link interface as the primary or secondary control IP address of the Engine.
|
Second Interface ID | (When Type is Aggregated Link in High Availability Mode) The second interface in the aggregated link for high availability Mode. |
Additional Interface(s) | (When Type is Aggregated Link in Load Balancing Mode) Lists interfaces that you have added for an aggregated link. Click Add to add a row to the table, or Remove to remove the selected row. |

Virtual Resource section (Master Engines only) |
|
Virtual Resource |
The Virtual Resource associated with the interface. Select the same Virtual Resource in the properties of the Virtual Engine to add the Virtual Engine to the Master Engine. If the interface is to be used for the Master Engine system communications, select None. For Master Engines that host Virtual Engines, you can select Multiple Virtual Resources to allow several Virtual Engines to share a single physical interface. To add multiple Virtual Resources for Virtual IPS engines or Virtual Layer 2 Engines, add VLAN Interfaces to the Physical Interface, then select a Virtual Resource in the properties of each VLAN Interface. |
Allow VLAN Definition in Virtual Engine | (When the Virtual Resource option is a single Virtual Resource) When selected, you can add VLAN Interfaces to the automatically created physical interfaces in the Virtual Secure SD-WAN Engines that are associated with this interface. |
Virtual Engine Interface ID | (When the Virtual Resource option is a single Virtual Resource) Specifies the Interface ID of the Physical Interface in the Virtual Engine that is associated with this interface. |
Cluster MAC Address | (When the Virtual Resource option is a single Virtual Resource) Specifies a MAC address for the Master Engine. Do not use the MAC address of any actual network card on any of the Master Engine nodes. |
Interface Throughput Limit | (When the Virtual Resource option is a single Virtual Resource) Enter the throughput for the link on this interface as megabits per second. If the Virtual Resource element has a limit defined, the limit defined in that element is always used. |
Virtual Resources table | (When the Virtual Resource option is Multiple Virtual Resources) Select the Virtual Resources that you want to use for the associated Virtual Engines. Click Add to add an element to the table, or Remove to remove the selected element. |
Virtual Resource | The selected Virtual Resource element. |
Interface ID | Specifies the Interface ID of the Physical Interface in the Virtual Engine that is associated with this interface. |
Throughput Limit | Enter the throughput for the link on this interface as megabits per second. If the Virtual Resource element has a limit defined, the limit defined in that element is always used. |
MAC Address Prefix | (When the Virtual Resource option is Multiple Virtual Resources) Enter a unique unicast MAC address prefix (the first five octets of a MAC address) that identifies the interface and groups the Virtual Engines that use this interface. Each individual Virtual Engine is identified by a full unique unicast MAC address (the prefix and the final octet which is taken from the Virtual Engine ID). |

Zone
(Optional) |
Select the network zone to which the interface belongs. Click Select to select an element, or click New to create an element. |
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.

MTU
(Optional) |
The maximum transmission unit (MTU) size on the connected link. Either enter a value between 400–65535 or select a common MTU value from the list. If the interface is a Physical Interface, the same MTU is automatically applied to any VLANs created under it. The default value (also the maximum standard MTU in Ethernet) is 1500. Do not set a value larger than the standard MTU, unless you know that all devices along the communication path support it. To set the MTU for a Virtual Engine, you must configure the MTU for the interface on the Master Engine that hosts the Virtual Engine, then refresh the policy on the Master Engine and the Virtual Engine. |
LLDP Mode | Specifies how LLDP is used on the interface.

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. |
