Configuring a Chassis Cluster and Redundancy Groups—Quick Configuration

You can use J-Web Quick Configuration to quickly configure chassis clusters, as well as their redundancy groups. See Figure 102.

Caution: Before you can use J-Web Quick Configuration to configure the chassis cluster parameters, you must:

  • Set the cluster ID and node ID for each node.
  • Configure management interfaces.

Figure 102 shows the Chassis Cluster page.

Chassis Cluster Page

To configure chassis cluster with J-Web Quick Configuration:

  1. Select Configuration > Quick Configuration > Chassis Cluster.
  2. Fill in the parameter settings as described in Table 170.
  3. Click one of the following buttons:

Go on to Configuring Redundant Ethernet Interfaces—Quick Configuration.

Field

Function

Action

Chassis Cluster

Redundant ether-Interface Count

Specifies the number of redundant Ethernet Interfaces to be created for the cluster.

Specify a value between 1 and 128.

For SRX 210 devices, specify a value between 1 and 8.

Heartbeat Interval

Specifies, in milliseconds, how often heartbeats are sent out to the other nodes in the cluster.

The default heartbeat interval is 1000.

Specify a value between 1000 and 1200.

Heartbeat Threshold

Specifies the number of consecutive missed heartbeats that indicate a cluster failure.

The default number is 3.

Specify a value between 3 and 8.

Nodes

Specifies the nodes to be used for the chassis cluster.

To specify a node, select the node from the list and click Add.

To delete a node, select the node you want to delete and click Delete.

Group Number

Displays the selected redundancy group information or creates or modifies a redundancy group.

Select a group number from the list of configured redundancy groups.

  • To modify information for a redundancy group, select the corresponding group number. Specify a value between 1 and 128.
  • To create a new redundancy group:
    • Assign a group ID to the redundancy group. Specify a value between 1 and 128.
    • Configure the redundancy group with information described in the rest of this table.

Gratuitous ARP Count

For a redundancy group, specifies the number of gratuitous Address Resolution Protocol (ARP) requests that a newly elected master sends out on the active redundant Ethernet interface child links to notify network devices of a change in mastership on the redundant Ethernet interface links.

The default value is 4.

Specify a value between 1 and 16.

Preempt

For a redundancy group, allows a node with a better priority to initiate a failover. By default, this feature is disabled. When disabled, a node with a better priority does not initiate a redundancy group failover (unless some other factor, such as faulty network connectivity identified for monitored interfaces, causes a failover).

Select the check box.

Priorities

For a redundancy group, specifies the priority value of each node. The redundancy group becomes primary on the node with the best (higher) priority.

By default, this feature is disabled.

Select a node and a priority number, then click Add. The value is a number between 1 and 225.

Interface Monitor

For a redundancy group, specifies the interfaces to be monitored by the redundancy group and their respective weights.

Select the interface from the list and enter its weight. The value is a number between 1 and 255.
