Configuring the single-interface WAN option using the wizard

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.

Configure the primary node:

Enable the CLI configuration mode:

node1-hostname > enable
node1-hostname # configure terminal

Respond to the basic Central Management System configuration questions the wizard asks, as described in the Central Management System Administration Guide.

Start the configuration wizard:

node1-hostname (config) # configuration jump-start

Respond to the cluster configuration questions the wizard asks, as described below.
Configure CM HA?
Enter yes.
CM HA uses ether1 as CM HA default interface. Do you want to change CM HA interfaces?
Enter yes.
CM HA default interface name?
Enter the name of the default HA interface.
CM HA default interface IPv4 address and masklen?
Enter the default HA interface IPv4 address and mask length.
Configure CM HA default interface gateway?
Enter yes.
Changing interface gateway will affect IP routing table. Do you still want to configure CM HA default interface gateway?
Enter yes.
CM HA default interface gateway IPv4 address?
Enter the IPv4 address of the default HA interface's default gateway or next-hop device.
Neighbor node CM HA default interface IPv4 address and masklen?
Enter the other node's default HA interface IPv4 address and mask length.
Do you want to configure CM HA backup interface?
Enter no.
Configure this node as primary CM HA node?
Enter yes.
Wait for all services to be in the "running" state:
```
node1-hostname (config) # show ha status
```

Configure the secondary node:

Enable the CLI configuration mode:

node2-hostname > enable
node2-hostname # configure terminal

Start the configuration wizard:

node2-hostname (config) # configuration jump-start

CM HA default interface name?
Enter the name of the default HA interface.

Enter the default HA interface IPv4 address and mask length.
Configure CM HA default interface gateway?
Enter yes.
Changing interface gateway will affect IP routing table. Do you still want to configure CM HA default interface gateway?
Enter yes.
CM HA default interface gateway IPv4 address?
Enter the IPv4 address of the default HA interface's default gateway or next-hop device.
Neighbor node CM HA default interface IPv4 address and masklen?
Enter the other node's default HA interface IPv4 address and mask length.
Do you want to configure CM HA backup interface?
Enter no.
Configure this node as primary CM HA node?
Enter no.
CM HA primary node IP address?
Enter the IPv4 address of the primary node.
CM HA primary node admin account password?
Enter the password for the primary node's remote admin user.
Confirm CM HA primary node admin account password?
Re-enter the password for the primary node's remote admin user.

Note

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