12.5.4. Cluster settings

This section describes how to configure configuration and high availability clusters.

12.5.4.1. Configuration cluster settings

This section is located at the settings device-mgmt configuration-cluster level.

To update an existing cluster mode, use the following command:

Admin@UGOS# set settings device-mgmt configuration-cluster <node-name>

Available parameters:

Parameter

Description

name

Change the cluster node name.

description

Update the cluster node description.

ip

Set the IP address of the interface included in the zone allocated to the cluster.

To delete and display cluster node settings, use the following commands:

Admin@UGOS# delete settings device-mgmt configuration-cluster <node-name> 

Admin@UGOS# show settings device-mgmt configuration-cluster <node-name>

12.5.4.2. Settings for high availability clusters

You apply settings to HA clusters at the settings device-mgmt ha-cluster level.

To create an HA cluster, use the following command:

Admin@UGOS# create settings device-mgmt ha-cluster

Provide the following parameters:

Parameter

Description

enabled

Enable/disable the HA cluster:

  • on.

  • off.

name

HA cluster name.

description

HA cluster description.

mode

Select cluster operation mode:

  • active-passive: Active-Passive mode (one server operates as the master node that processes traffic while the remaining servers act as backup).

  • active-active: Active-Active mode (one server operates as the master node that distributes traffic to all other nodes in the cluster).

master-node

Select the Master node (will list currently active cluster nodes).

ha-cluster-id

Configure session synchronization in the cluster:

  • <num>: multicast cluster ID (can take values from 0 to 8). User session synchronization (except for sessions that use a proxy server, such as HTTP/S traffic) is enabled automatically.

  • off: disable user session synchronization.

virtual-router-id

Virtual Router ID (VRID).

nodes

Select configuration cluster nodes to combine them into an HA cluster.

virtual-ips

Set the virtual IP address for the cluster and select an interface for each node (the VRRP service should be enabled in the selected interface zone; for more details on how to configure zones using the CLI, see the section Zones).

To add a virtual IP address to the cluster, use the following command:

Admin@UGOS# create settings device-mgmt ha-cluster virtual-ips <virtual-ips-filter> <virtual-ip-info>

Available parameters for <virtual-ips-filter>:

  • new: create a virtual IP address for the specific cluster.

  • <ip>: change data for the selected virtual address.

Available parameters for <virtual-ip-info>:

  • ip: set an IP address for the HA cluster (format: IP/mask).

  • ha-interfaces: set interfaces for the cluster nodes (format: node-name/interface).

To update cluster settings, use the following command:

Admin@UGOS# set settings device-mgmt ha-cluster <cluster-name>

The list of parameters is identical to the one used to create an HA cluster.

To delete a cluster, use the following command:

Admin@UGOS# delete settings device-mgmt ha-clusters <cluster-name>

You can also delete individual parameters:

  • nodes.

  • virtual-ips.

To display information about all HA clusters, use the following command:

Admin@UGOS# show settings device-mgmt ha-cluster

To display information about a specific HA cluster, use the following command:

Admin@UGOS# show settings device-mgmt ha-cluster <cluster-name>
