Securing Controller-to-Controller Communication

xSec can be used to secure data and control traffic passed between two Dell controllers. The only requirement is that both Dell controllers be members of the same VLAN. To establish a point-to-point tunnel between the two Dell controllers, you need to configure the following for the connecting ports on each controller:

•The MAC address of the xSec tunnel termination point. This would be the MAC address of the “other” controller.

•A 16-byte shared key used to authenticate the Dell controllers to each other. You must configure the same shared key on both Dell controllers.

•The VLAN IDs for the VLANs that will extend across both the Dell controllers via the xSec. Figure 279 shows an example network where two Dell controllers are connected to the same VLAN, VLAN 1. On controller 1, you configure the MAC address of controller 2 for the xSec tunnel termination point. On controller 2, you configure the MAC address of controller 1 for the xSec tunnel termination point. On both Dell controllers, you configure the same 16-byte shared key and the IDs for the VLANs which are allowed to pass through the xSec tunnel.

Configuring Controllers for xSec

The following sections describe how to use the WebUI or CLI to configure the port that connects to the wired network on which the other controller is installed. Other chapters in this manual describe the configuration of VLANs.

In the WebUI

1.On each controller, navigate to the Configuration > Network > Port page.

2.Click on the port to be configured.

3.Select the VLAN from the drop-down list.

4.Configure the xSec point-to-point settings:

a.Enter the MAC address of the tunnel termination point (the “other” controller’s MAC address).

b.Enter the key (for example, 1234567898765432) used by xSec to establish the tunnel between the Dell controllers.

c.Select the VLANs that would be allowed across the point-to-point connection from the Allowed VLANs drop- down menu, and click the <-- button.

5.Click Apply.

In the CLI

For Controller 1:

interface gigabitethernetfastethernet slot/port vlan 1

xsec point-to-point 10:11:12:13:14:15 1234567898765432 allowed vlan 101,200,250

For Controller 2:

interface gigabitethernetfastethernet slot/port
