Configuring Base Interfaces
You view and modify settings for the appliance primary and auxiliary interfaces in the Networking: Base Interfaces page.
When you initially ran the Configuration wizard, you set required settings for the base interfaces for the SteelHeads. Only use the controls on this page if you require modifications or additional configuration:
•  Primary Interface - On the appliance, the primary interface is the port you connect to the LAN switch. The primary interface is the appliance management interface. You connect to the primary interface to use the Management Console or the CLI.
•  Auxiliary Interface - On the appliance, the auxiliary interface is an optional port you can use to connect the appliance to a non-Riverbed network management device. The IP address for the auxiliary interface must be on a subnet different from the primary interface subnet.
•  Main Routing Table - Displays a summary of the main routing table for the appliance. If necessary, you can add static routes that might be required for out-of-path deployments or particular device management subnets.
IPv6 Support
RiOS 7.0 extended support for IPv6 traffic with packet-mode optimization, and RiOS 8.5 and later further enhances their IPv6 capabilities by supporting autodiscovery and fixed-target rules. By using autodiscovery or fixed-target in-path rules, RiOS can apply transport and application streamlining techniques (similarly as it does for TCP connections over IPv4) to improve the user experience as the transition to IPv6 continues.
IPv6 is enabled by default in RiOS 8.5 and later. The SteelHead support for IPv6 is twofold:
•  Managing SteelHeads - Support for management access using IPv6 IP addresses on primary and auxiliary interfaces.
•  Optimizing IPv6 traffic using SteelHeads - SteelHeads can optimize IPv6 traffic.
For details about IPv6 deployments, see the SteelHead Deployment Guide and the SteelHead Management Console User’s Guide for SteelHead CX.
For details about IPv6 support for SteelHead CX by feature and any limitations and special considerations, see the SteelHead Management Console User’s Guide for SteelHead CX.
To display and modify the configuration for base interfaces
1. Choose Administration > Networking: Base Interfaces to display the Base Interfaces page.
Figure: Modifying the Base Interfaces
2. Under Primary Interface, complete the configuration as described in this table.
Control
Description
Enable Primary Interface
Enables the appliance management interface, which can be used for both managing the SteelHead and serving data for a server-side out-of-path (OOP) configuration.
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.
Note: 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 hexadecimal 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 this 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.
3. Under Auxiliary Interface, complete the configuration as described in this table.
Control
Description
Enable Aux Interface
Enables an auxiliary interface, which can be used only for managing the SteelHead. It cannot be used for an out-of-path (OOP) SteelHead data service. Typically this is used for device-management networks.
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.
Note: The primary and in-path interfaces can share the same 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.
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 hexadecimal 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 this example, 60 is the prefix:
2001:38dc:52::e9a4:c5:6282/60
 
Note: You cannot set an IPv6 address dynamically using a DHCP server.
Speed and Duplex
Speed - Select the 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 on the device manually.
The speed and duplex must match (LAN and WAN) in an in-path configuration. To avoid a speed and duplex mismatch, configure your LAN external pair to match the WAN external pair.
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.
Apply
Applies your settings to the running configuration.
