Additional Information
The destination gateway of each route must match the subnet of at least one configured IP
l
address listed in the IP Address Table. If no match is found, an error displays stating that the
route's destination gateway is not reachable.
In the example shown below, to reach a host on the 10.50.50.x subnet, you would enter
l
10.50.50.0 for destination network, 255.255.255.0 for the destination netmask, and 10.20.20.1 as
the destination gateway.
5. Click Update to save the changes you made to the Routing Details table. (Clicking Update does not
yet apply the new network settings to the DXi6900.)
6. Click Delete to remove IP routing information for the selected interface. Or click Undo to revert all
current Routing Details changes to the last update.
Applying Network Settings
For network changes to take effect, you must apply the changes, finalize the confirmation, and reboot the
system. To apply all changed settings on the Network page to the DXi6900, click Apply at the bottom of the
page. Follow the prompts to confirm the changes and reboot the system.
Note: To revert all network settings to the initial state and undo all changes, click the Reset button.
Understanding Interface Routing
For a network on the interface to communicate with a host located on a different subnet, you must specify
routing information in the Routing Details section. Routing is used to direct outgoing traffic from a network
interface on the DXi to an IP address in another subnet by means of a destination gateway. Responses from
the destination are routed back to the DXi using the gateway specified for the interface in the IP Address
Table section.
In addition, when configuring segmented network interfaces, if the source DXi replication, data, and
management interfaces are on the same subnet, you must add a host route on the source DXi to make sure
the replication interface is correctly selected when replicating data to the target DXi.
See the following examples for details:
Example 1: Segments and Target on Different Subnets
In the example below (see
traffic and one for data traffic:
The management interface is assigned to the 10.30.24.x subnet in the IP Address Table section. This
l
subnet connects to the corporate network by mean of the default gateway (10.30.24.1).
The data interface is assigned to the 10.20.20.x subnet in the IP Address Table section. This subnet
l
connects to a gateway at 10.20.20.1.
Using the data interface, the DXi needs to connect to a backup host that is on the 10.50.50.x subnet.
