Network Configuration Examples

DXi Connected to Two Different Networks Through Two Bonds

In this example, the bonded interfaces on the DXi are connected to two different subnets. You can configure two different default gateways for the subnet.

DXi With Only Two Independent Ports Being Used

In this example, there are only two independent customer ports that are configured. These independent customer ports need to be connected to two independent non-aggregated ports on the switch. You can configure the IP subnet dependent gateways.

DXi With Three Bonds of Two Ports Each (2 x 2 x 2 Networks)

In this example, there are three bonds, and each bond has two ports. Ensure the switch ports are appropriately aggregated and the gateways, if applicable, are configured.

DXi With One Bond and Two Independent Interfaces (1 x 1 x n-Data Networks)

In this example, the two independent interfaces need to be connected to a non-aggregated port on a switch. The bonded ports are connected to appropriately link the aggregated switch ports.

Configure a similar setup

Display the existing configuration:
syscli ‑‑list interface
Delete the default bond configuration with all customer ports connected together:
syscli ‑‑del netcfg ‑‑devname bond0
Configure Bond 0 for IP Address 1 and the replication source, and configure Gateway 1, as needed:
syscli ‑‑add netcfg ‑‑devname bond0:1 ‑‑slaves eth1, eth2, eth3, eth4 ‑‑ipaddr IPADDR1 ‑‑netmask NETMASK1 ‑‑gateway GATEWAY1 ‑‑segments REP
Configure Eth0 for IP Address 2, and configure Gateway 2, as needed:
syscli ‑‑add netcfg ‑‑devname eth0:1 ‑‑ipaddr IPADDR2 ‑‑netmask NETMASK2 ‑‑gateway GATEWAY2 ‑‑segments REP
Configure Eth5 for IP Address 3, and configure Gateway 3, as needed:
syscli ‑‑add netcfg ‑‑devname eth5:1 ‑‑ipaddr IPADDR3 ‑‑netmask NETMASK3 ‑‑gateway GATEWAY3 ‑‑segments MGMT

Tip

If you are configuring a replication segment for a device interface along with other segments on the same subnet, make sure to add a route that exclusively reserves the replication segment for replication between a source and a target DXi, as shown in the following examples:

syscli ‑‑add netcfg ‑‑devname eth1:1 ‑‑ipaddr IPADDR1 ‑‑netmask NETMASK1 ‑‑gateway GATEWAY1 ‑‑segments DATA,MGMT

syscli ‑‑add netcfg ‑‑devname eth2:1 ‑‑ipaddr IPADDR2 ‑‑netmask NETMASK1 ‑‑ gateway GATEWAY1 ‑‑segments REP

syscli ‑‑add route ‑‑devname eth2:1 ‑‑network DEST_IP_ADDRESS ‑‑netmask 255.255.255.255 ‑‑gateway IPADDR2

DXI With All Customer Interfaces Used Independently

In this example, data traffic comes from two media servers going thru GbE port 1 and the two 10 GbE ports. Replication and management traffic are routed to GbE port 0.

Delete a Bond and Set Up Independent Interfaces

This example demonstrates how to delete a bond that has eth0 and eth1 as slaves and set them up as independent interfaces.

Display the output of the current runtime network values.
Runtime values are values currently being used by the network service. You must first configure values using ‑‑add netcfg and ‑‑del netcfg. In order for these values to become runtime values, you must reboot the system to restart the network service. Use the syscli ‑‑nodemanage ‑‑reboot command to reboot the system.
