Setting the Node ID and Cluster ID

After connecting the two devices together, you configure a cluster ID and a node ID. A cluster ID identifies the cluster that the two nodes belong to. A node ID identifies a unique node within a cluster.

Before You Begin

Read:

The system uses node IDs and cluster IDs to apply the correct configuration for each node when you use the apply-group command described in Configuring Chassis Cluster Information . The node ID and cluster ID statements are written to the EPROM, and when the system is rebooted, they take effect.

You can deploy up to 15 clusters in a Layer 2 domain. Each cluster is defined by a cluster-id value within the range of 1 through 15. A device can belong to only one cluster at any given time. Nodes in a cluster are numbered 0 and 1.

CLI Configuration

To set the node IDs and cluster IDs, connect to each device through the console port and enter the following operational commands, then reboot the system.

Enter the cluster ID and node ID information for the first node. If you want redundancy groups to be primary on this node when priority settings for both nodes are the same, make it node 0.
user@host> set chassis cluster cluster-id 1 node 0 warning: A reboot is required for chassis cluster to be enabled
Enter the cluster ID and node ID for the other node. If you want redundancy groups to be secondary on this node when priority settings for both nodes are the same, make it node 1.
user@host> set chassis cluster cluster-id 1 node 1 reboot Successfully enabled chassis cluster. Going to reboot now.

After you set the cluster ID and node ID for each node and the system reboots, the built-in interfaces are automatically renamed (see Table 112). Use the show chassis cluster status operational command to view node status.

{primary:node1}

user@host# show chassis cluster status

Cluster ID: 3
Node name                  Priority     Status    Preempt  Manual failover

Redundancy group: 0 , Failover count: 1
    node0                   254         secondary no       no
    node1                   2           primary   no       no

Redundancy group: 1 , Failover count: 1
    node0                   101         Secondary no       no
    node1                   99          primary   no       no

When you complete the chassis cluster basic configuration, any subsequent configuration changes you make are automatically synchronized on both nodes.
