Modifying Host and Network Interface Settings : Modifying Data Interfaces
  
Modifying Data Interfaces
You view and modify settings for data interfaces in the Networking > Networking: Data Interfaces page. (This page is available only if you have a network card installed in any slot of the appliance except slot 0.)
SteelHead EX appliances support installing a four-port TX copper Gigabit Ethernet Card (410-00047-01/NIC-003-4TX) and configuring the card with data interfaces. You can use the data interfaces for SteelFusion iSCSI and Rdisk traffic and for ESXi NICs in the Virtual Services Platform.
To use data interfaces for ESXi, you must insert the network card in slot 1 of the appliance. You can configure NICs in other slots for data interfaces to be used by RiOS and SteelFusion.
Data interfaces are identified by ethX_Y notation, where eth denotes a data NIC, X denotes the slot, and Y denotes the interface/port on the slot (such as eth1_0, eth1_1, eth1_2 and eth1_3).
When you add a NIC to a Steelhead EX appliance, the system automatically configures the card as additional LAN/WAN interfaces and only usable for optimization. Follow the steps in this section to configure it as a NIC with data interfaces.
Note: This procedure is not supported on the SteelHead EX560 and EX760 models.
To display and modify the configuration for data interfaces
1. Choose Networking > Networking: Data Interfaces to display the Data Interfaces page.
2. To enable data interfaces on a network card installed in slot 1 of the appliance, under Interface settings select the “Use card in slot 1 for data interfaces” option and click Apply.
3. Reboot the appliance.
4. Return to the Data Interface configuration page and under Data Interface Settings, click an interface and complete the configuration as described in this table.
Control
Description
Enable Interface
Enables the data interface, which can be used for either SteelFusion or the Virtual Services Platform.
Obtain IPv4 Address Automatically
Select this option to automatically obtain the IP address from a DHCP server. A DHCP server must be available so that the system can request the IP address from it.
Important: 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
Select this option to send the hostname with the DHCP request for registration with Dynamic DNS. The hostname is specified in the Networking > Networking: Host Settings page.
Specify IPv4 Address Manually
Select this option if you do not use a DHCP server to set the IPv4 address. Specify these settings:
•  IPv4 Address - Specify an IP address.
•  IPv4 Subnet Mask - Specify a subnet mask.
•  Default IPv4 Gateway - Specify the default gateway IPv4 address. The default gateway must be in the same network as the primary interface. You must set the default gateway for in-path configurations.
Do Not Assign An IPv4 Address
Enables the interface without assigning an IP address. Use this option if all traffic on this interface is for VSP.
Specify IPv6 Address Manually
Select this option and specify these settings to set an IPv6 address.
•  IPv6 Auto-Assigned - Displays the link-local address that is automatically generated when IPv6 is enabled on the base interfaces.
•  IPv6 Address - Specify 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 - Specify a prefix. The prefix length is 0 to 128, separated from the address by a forward slash (/). In the following example, 60 is the prefix:
2001:38dc:52::e9a4:c5:6282/60
 
•  IPv6 Gateway - Specify the gateway IP address. The gateway must be in the same network as the primary interface.
Note: You cannot set an IPv6 address dynamically using a DHCP server.
Speed and Duplex
Speed - Select a speed from the drop-down list. The default value is Auto.
Duplex - Select 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
Specify the MTU value. The MTU is the largest physical packet size, measured in bytes, that a network can send. The default value is 1500.
5. Click Apply to apply your changes to the running configuration.
6. Click Save to save your changes permanently.
To configure routes for IPv4
•  Under Main IPv4 Routing Table, you can configure a 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 as described in this table.
Control
Description
Add a New Route
Displays the controls for adding a new route.
Destination IPv4 Address
Specify the destination IP address for the out-of-path appliance or network management device.
IPv4 Subnet Mask
Specify the subnet mask.
Gateway IPv4 Address
Specify the IP address for the gateway. The gateway must be in the same network as the primary or auxiliary interface you are configuring.
Interface
Select an interface for the IPv4 route from the drop-down menu.
Add
Adds the route to the table list.
Remove Selected
Select the check box next to the name and click Remove Selected.
The Management Console writes your configuration changes to memory.
To configure routes for IPv6
•  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 as described in this table.
Control
Description
Add a New Route
Displays the controls for adding a new route.
Destination IPv6 Address
Specify the destination IP address.
IPv6 Prefix
Specify a prefix. The prefix length is from 0 to 128 bits, separated from the address by a forward slash (/).
Gateway IPv6 Address
Specify the IP address for the gateway. The gateway must be in the same network as the primary or auxiliary interface you are configuring.
Interface
Select an interface for the IPv6 route from the drop-down menu.
Add
Adds the route to the table list.
Remove Selected
Select the check box next to the name and click Remove Selected.
