Configuring the single-interface WAN option using the CLI

Use the commands in this section to configure the basic settings for a single-interface Central Management System cluster in a WAN deployment that uses a non-default interface.

Configuring the primary node

Perform the procedures in this section in order to configure the primary node.

Configure the default HA interface:

Configure the default HA interface address:
```
node1-hostname (config) # interface <interface name> ip address <ip address> /<mask>
```
where <ip address> is the IPv4 address of the default HA interface, and <mask> is the mask length prefixed by a slash (for example, /24) or a netmask (for example, 255.255.255.0).

Prevent the default HA interface from becoming disabled:

node1-hostname (config) # no interface <interface name> shutdown

Set the static route for the default HA interface on the primary node:
```
node1-hostname (config) # ip route <primary network prefix> /<mask> <gateway IP> <interface name>
```
where:
- <network prefix> is the IPv4 network prefix specifying the network.
- <mask> is the mask length prefixed by a slash (for example, /24) or a netmask (for example, 255.255.255.0).
- <gateway IP> is the IPv4 address of the gateway or next-hop device.
- <interface name> is the name of the default HA interface.

Set the static route for the default HA interface on the secondary node:

node1-hostname (config) # ip route <secondary network prefix> /<mask> <interface name>

Enable the interface as the default HA interface:

node1-hostname (config) # ha interface default <interface name>

Verify and save your changes:

Start the cluster engine:

Configuring the secondary node

Perform the procedures in this section in order to configure the secondary node.

Configure the default HA interface:

Configure the default HA interface address:
```
node2-hostname (config) # interface <interface name> ip address <ip address> /<mask>
```
where <ip address> is the IPv4 address of the default HA interface, and <mask> is the mask length prefixed by a slash (for example, /24) or a netmask (for example, 255.255.255.0).

Prevent the default HA interface from becoming disabled:

node2-hostname (config) # no interface <interface name> shutdown

Set the static route for the default HA interface on the secondary node:
```
node2-hostname (config) # ip route <secondary network prefix> /<mask> <gateway IP> <interface name>
```
where:
- <network prefix >is the IPv4 network prefix specifying the network.
- <mask> is the mask length prefixed by a slash (for example, /24) or a netmask (for example, 255.255.255.0).
- <gateway IP> is the IPv4 address of the gateway or next-hop device.
- <interface name> is the name of the default HA interface.

Set the static route for the default HA interface on the primary node:

node2-hostname (config) # ip route <primary network prefix> /<mask> <interface name>

Enable the interface as the default HA interface:

node2-hostname (config) # ha interface default <interface name>

Add the node to the cluster:

Add the node to the cluster:

node2-hostname (config) # ha node join <primary node IP addr>

When prompted, enter the password for the primary node's remote admin user:
```
Enter password for admin account on primary node: ********
```

Verify and save your changes:

Start the cluster engine:

Note

You can perform a manual failover to test the cluster.Failing over manually using the CLI

Examples

The following example configures the primary node in the single-interface WAN deployment using a non-default interface.

node1 (config) # interface ether3 ip address 10.2.140.25 /26
node1 (config) # no interface ether3 shutdown
node1 (config) # ip route 10.2.0.0 /26 10.2.140.1 ether3
node1 (config) # ip route 10.17.0.0 /24 ether3
node1 (config) # ha interface default ether3
node1 (config) # show ha configuration
...
node1 (config) # write memory
node1 (config) # ha engine restart
...
node1 (config) # show ha status
...

The following example configures the secondary node in the single-interface WAN deployment using a non-default interface.

node2 (config) # interface ether3 ip address 10.17.220.25 /24
node2 (config) # no interface ether3 shutdown
node2 (config) # ip route 10.17.0.0 /24 10.17.220.254 ether3
node2 (config) # ip route 10.2.0.0 /26 ether3
node2 (config) # ha interface default ether3
node2 (config) # ha node join 10.2.127.144
Enter password for admin account on primary node: ********
Node joining has started
Please check the status with CLI 'show ha configuration'. 
node2 (config) # show ha configuration
...
node2 (config) # write memory
node2 (config) # ha engine restart
...
node2 (config) # show ha status
...
