Table 7: show chassis cluster status Output Fields

Field Name

Field Description

Cluster ID

ID number (1-15) of a cluster is applicable for releases upto 12.1X45-D10. ID number (1-255) is applicable for releases 12.1X45-D10 and later. Setting a cluster ID to 0 is equivalent to disabling a cluster.

Redundancy-Group

ID number (1-128) of a redundancy group in the chassis cluster.

Node name

Node (device) in the chassis cluster (node0 or node1).

Priority

Assigned priority for the redundancy group on that node.

Status

State of the redundancy group (Primary, Secondary, Lost, or Unavailable).

  • Primary—Redundancy group is active and passing traffic.
  • Secondary—Redundancy group is passive and not passing traffic.
  • Lost—Node loses contact with the other node through the control link. Most likely to occur when both nodes are in a cluster and due to control link failure, one node cannot exchange heartbeats, or when the other node is rebooted.
  • Unavailable—Node has not received a single heartbeat over the control link from the other node since the other node booted up. Most likely to occur when one node boots up before the other node, or if only one node is present in the cluster.

Preempt

  • Yes: Mastership can be preempted based on priority.
  • No: Change in priority will not preempt the mastership.

Manual failover

  • Yes: If the Mastership is set manually through the CLI with the request chassis cluster failover node or request chassis cluster failover redundancy-group command. This overrides Priority and Preempt.
  • No: Mastership is not set manually through the CLI.
