About data interface settings
You can configure the data interfaces under Networking > Networking: Data Interfaces.
Under Data Interface Settings, click an interface and complete the configuration with these options:
Enable Interface
Enables the data interface, which can be used for the Core.
Obtain IPv4 Address Automatically
Obtains the IP address from a DHCP server. A DHCP server must be available so that the system can request the IP address from it. The primary and in-path interfaces can share the same network subnet. The primary and auxiliary interfaces cannot share the same network subnet.
Enable IPv4 Dynamic DNS
Sends the hostname with the DHCP request for registration with Dynamic DNS. The hostname is specified under Networking > Networking: Host Settings.
Specify IPv4 Address Manually
Indicates you do not use a DHCP server to set the IPv4 address. Specify these settings:
• IPv4 Address
• IPv4 Subnet Mask
• Default IPv4 Gateway
The default gateway must be in the same network as the primary interface. You must set the default gateway for in-path configurations.
Specify IPv6 Address Manually
IPv6 Auto-Assigned
Displays the link-local address that is automatically generated when IPv6 is enabled on the base interfaces.
IPv6 Address
Specifies an IP address using this format: eight 16-bit hex strings separated by colons, 128-bits. For example:
2001:38dc:0052:0000:0000:e9a4:00c5:6282
You do not need to include leading zeros. For example:
2001:38dc:52:0:0:e9a4:c5:6282
You can replace consecutive zero strings with double colons (::). For example:
2001:38dc:52::e9a4:c5:6282
IPv6 Prefix
Specifies a prefix. The prefix length is 0 to 128, separated from the address by a forward slash (/). In this example, 60 is the prefix:
2001:38dc:52::e9a4:c5:6282/60
IPv6 Gateway
Specifies the gateway IP address. The gateway must be in the same network as the primary interface. You cannot set an IPv6 address dynamically using a DHCP server.
Speed and Duplex
Speed
Specifies a speed from the drop-down list. The default value is Auto.
Duplex
Specifies Auto, Full, or Half from the drop-down list. The default value is Auto.
If your network routers or switches do not automatically negotiate the speed and duplex, be sure to set them manually.
The speed and duplex must match (LAN and WAN) in an in-path configuration. If they do not match, you might have a large number of errors on the interface when it is in bypass mode, because the switch and the router are not set with the same duplex settings.
MTU
Specifies the MTU value. The MTU is the largest physical packet size, measured in bytes, that a network can send. The default value is 1500.
IPv4 routes
Under Main IPv4 Routing Table, you can configure static routing in the main routing table for out-of-path deployments or if your device-management network requires static routes. You can add or remove routes from the table list with these configuration options:
Destination IPv4 Address
Specifies the destination IP address for the out-of-path appliance or network management device.
IPv4 Subnet Mask
Specifies the subnet mask.
Gateway IPv4 Address
Specifies the IP address for the gateway. The gateway must be in the same network as the primary or auxiliary interface you are configuring.
Interface
Specifies an interface for the IPv4 route from the drop-down list.
The Management Console writes your configuration changes to memory.
IPv6 routes
Under Main IPv6 Routing Table, you can configure static routing in the main routing table if your device-management network requires static routes. You can add or remove routes from the table list with these configuration options:
Destination IPv6 Address
Specifies the destination IP address.
IPv6 Prefix
Specifies a prefix. The prefix length is from 0 to 128 bits, separated from the address by a forward slash (/).
Gateway IPv6 Address
Specifies the IP address for the gateway. The gateway must be in the same network as the primary or auxiliary interface you are configuring.
Interface
Specifies an interface for the IPv6 route from the drop-down menu.
The Management Console writes your configuration changes to memory.
