The fabric is the back-to-back data connection between the nodes in a cluster. Traffic on one node that needs to be processed on the other node or to exit through an interface on the other node passes over the fabric. Session state information also passes over the fabric.
Before You Begin
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.
In a J Series chassis cluster, you can configure any pair of Gigabit Ethernet interfaces to serve as the fabric between nodes.
For details about port and interface usage for management, control, and fabric links, see Table 111 and Table 112.
You cannot configure filters, policies, or services on the fabric interface. Fragmentation is not supported on the fabric link. The maximum transmission unit (MTU) size is 8,980 bytes. We recommend that no interface in the cluster exceed this MTU. Jumbo frame support on the member links is enabled by default.

Enter the following commands to join ge-0/0/1 on one node in the cluster and ge-7/0/1 on the other to form the fabric:
- user@host# set interfaces fab0 fabric-options member-interfaces ge-0/0/1
- user@host# set interfaces fab1 fabric-options member-interfaces ge-7/0/1
