Additional Information
l
The destination gateway of each route
must
match the subnet of at least one configured IP
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.
l
In the example shown below, to reach a host on the 10.50.50.x subnet, you would enter
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
), the DXi has two segmented interfaces, one for management
traffic and one for data traffic:
l
The management interface is assigned to the 10.30.24.x subnet in the
IP Address Table
section. This
subnet connects to the corporate network by mean of the default gateway (10.30.24.1).
l
The data interface is assigned to the 10.20.20.x subnet in the
IP Address Table
section. This subnet
connects to a gateway at 10.20.20.1.
l
Using the data interface, the DXi needs to connect to a backup host that is on the 10.50.50.x subnet.
