Example: Configuring Chassis Cluster Dual Fabric Links with Different Slots and Ports

Requirements

Before you begin, set the chassis cluster ID and chassis cluster node ID. See Example: Setting the Chassis Cluster Node ID and Cluster ID.

Overview

In most SRX Series devices in a chassis cluster, you can configure any pair of Gigabit Ethernet interfaces or any pair of 10-Gigabit interfaces to serve as the fabric between nodes. Interfaces on SRX210 devices are Fast Ethernet or Gigabit Ethernet (the paired interfaces must be of a similar type) and all interfaces on SRX100 devices are Fast Ethernet interfaces.

You cannot configure filters, policies, or services on the fabric interface. Fragmentation is not supported on the fabric link. The MTU size is 8980 bytes. We recommend that no interface in the cluster exceed this MTU size. Jumbo frame support on the member links is enabled by default.

This example illustrates how to configure the fabric link with dual fabric links with different slots and ports on each node.

Make sure you physically connect the RTO-and-probes link to the RTO-and-probes link on the other node. Likewise, make sure you physically connect the data link to the data link on the other node.

That is, physically connect the following two pairs:

• The node 0 RTO-and-probes link ge-2/1/9 to the node 1 RTO-and-probes link ge-11/0/0
• The node 0 data link ge-2/2/5 to the node 1 data link ge-11/3/0

Only the same type of interfaces can be configured as fabric children, and you must configure an equal number of child links for fab0 and fab1.

Note: If you are connecting each of the fabric links through a switch, you must enable the jumbo frame feature on the corresponding switch ports. If both of the fabric links are connected through the same switch, the RTO-and-probes pair must be in one virtual LAN (VLAN) and the data pair must be in another VLAN. Here too, the jumbo frame feature must be enabled on the corresponding switch ports.

Configuration

CLI Quick Configuration

To quickly configure the chassis cluster fabric with dual fabric links with matching slots and ports on each node, copy the following commands and paste them into the CLI:

Step-by-Step Procedure

1. Specify the fabric interfaces.
   {primary:node0}[edit]user@host# set interfaces fab0 fabric-options member-interfaces ge-2/1/9user@host# set interfaces fab0 fabric-options member-interfaces ge-2/2/5user@host# set interfaces fab1 fabric-options member-interfaces ge-11/0/0user@host# set interfaces fab1 fabric-options member-interfaces ge-11/3/0

Results

From configuration mode, confirm your configuration by entering the show interfaces command. If the output does not display the intended configuration, repeat the configuration instructions in this example to correct it.

For brevity, this show command output includes only the configuration that is relevant to this example. Any other configuration on the system has been replaced with ellipses (...).

If you are done configuring the device, enter commit from configuration mode.

Verification

Verifying the Chassis Cluster Fabric

Purpose

Verify the chassis cluster fabric.

Action

From operational mode, enter the show interfaces terse | match fab command.
