Adding a Node to an Existing Junos Space Fabric
When you configure a Junos Space Virtual Appliance as a Junos Space node by using the Junos Space CLI, Junos Space Network Management Platform automatically adds the first node to the fabric. By default, the Junos Space fabric contains this single node that provides complete Junos Space Platform functionality. For each additional node that you install and configure, you must add the node from the Junos Space Platform UI to represent the node in the fabric.
Before you begin, the following prerequisites must be in place:
Multicast must be enabled on the switches to which Junos Space nodes are connected.
IGMP-snooping needs to be disabled on the switches to which Junos Space nodes are connected. By default, IGMP-snooping is enabled on most switches.
All Junos Space nodes must be interconnected using a high-speed (1-Gbps or 100-Mbps) network with a maximum latency not exceeding 300 milliseconds.
Using the Junos Space CLI, you can configure a Junos Space Appliance or a Junos Space Virtual Appliance either as a Junos Space node or a Fault Monitoring and Performance Monitoring (FMPM) node. If you want to add a node to the fabric as a dedicated database node,it must be configured as a Junos Space node.
For information about how to configure a Junos Space Virtual Appliance as a Junos Space node, see Configuring a Junos Space Virtual Appliance as a Junos Space Node in the Junos Space Virtual Appliance Installation and Configuration Guide.
For information about how to configure a Junos Space Virtual Appliance as an FMPM node, see Configuring a Junos Space Virtual Appliance as a Standalone or Primary FMPM Node or Configuring a Junos Space Virtual Appliance as a Backup or Secondary FMPM Node for High Availability in the Junos Space Virtual Appliance Installation and Configuration Guide.
If you want to change an existing Junos Space node to an FMPM node or vice versa, you must reimage the appliance and reconfigure it as an FMPM node or a Junos Space node. For more information, refer to the Junos Space Appliance and Junos Space Virtual Appliance documentation.
Before you add a node to the Junos Space fabric, verify the following:
The version of Junos Space Platform installed on the node is the same as the version installed on other nodes in the fabric.
Ensure that no jobs are pending.
If a Junos Space node, a database node, or an FMPM node that is part of an existing fabric is deleted, then you need to reimage the node before the node can be readded to the fabric. Junos Space displays the following message when you try to add such nodes to an existing fabric:
The node you are trying to add was part of another fabric, please re-image the node before adding to this fabric.
Ensure that you are not adding a non-FMPM node as an FMPM node. Junos Space Platform displays the following message when you try to add such a node to the fabric:
Node agent is not running on {0}. Please make sure the node being added is not a specialized node.
From the Junos Space Platform UI, you can add a node to the Junos Space fabric by executing one of the following procedures, based on whether you have configured the node as a Junos Space node or as an FMPM node.
Adding a Junos Space Node to the Junos Space Fabric
To add a Junos Space node to the fabric:
Adding an FMPM Node to the Junos Space Fabric
To add an FMPM node to the fabric:
The node is added to the fabric and appears on the Fabric page. When you add a node, the node functions are automatically assigned by Junos Space Platform.
Obtaining Fingerprint of a Junos Space Node
In a Junos Space cluster, the fingerprint of a node helps in authenticating and authorizing the node.
Starting from Junos Space Network Management Platform Release 17.1R1, the Fingerprint field is introduced to authenticate and authorize a node before adding the node to a Junos Space cluster.
To obtain the fingerprint of a Junos Space node:
