Node Interfaces on SRX-series Chassis Clusters

Normally, on SRX-series devices, the built-in interfaces are numbered as follows:

For chassis clustering, SRX-series devices have a built-in management interface named fxp0. For SRX 5600 and SRX 5800 devices, control interfaces are configured on SPCs. For SRX 3400 and SRX 3600 devices, control interfaces are dedicated Gigabit Ethernet ports. Table 45 shows an example of how these interfaces could be named and numbered for SRX-series chassis clusters.

Note: See the appropriate Services Gateway Hardware Guide for details about SRX-series devices. The JUNOS Software Interfaces and Routing Configuration Guide provides a full discussion of the interface naming convention.

After you enable chassis clustering, the two chassis joined together cease to exist as individuals and now represent a single system. As a single system, the cluster now has twice as many FPC slots. (See Figure 53 and Figure 54.)
