configure node priority

configure node slot slot_id priority node_pri


Configures the priority of the node.

Syntax Description

slot_id Specifies the slot of the node. A is for the MSM/MM installed in slot A. B is for the MSM/MM installed in slot B.
node_pri Specifies the priority of the node. The default 0 gives MSM-A a higher priority over MSM-B. The range is 1 to 100; 0 means you have not configured a node priority.


Default node priority is 0.

Usage Guidelines

Use this command to configure the priority of the node. The lower the number, the higher the priority.

The node priority is part of the selection criteria for the primary node. The following list describes the parameters used to determine the primary node:
  • Node state—The node state must be STANDBY to participate in leader election and to be selected primary. If the node is in the INIT, DOWN, or FAIL states, the node will not participate in leader election.

  • Configuration priority—This is a user assigned priority. The configured priority is compared only after the node meets the minimum thresholds in each category for it to be healthy. Required processes and devices must not fail.

  • Software health—This represents the percent of processes available.

  • Health of secondary hardware components—This represents the health of switch components, such as the power supplies, fans, and so forth.

  • Slot ID—The MSM/MM slot where the node is installed (MSM-A or MSM-B).

If you do not configure any priorities, MSM-A has a higher priority than MSM-B.


The following command configures a priority of 2 for MSM-B:

configure node slot B priority 2
