    Interface Naming and Mapping

    Each network adapter defined for a vSRX is mapped to a specific interface, depending on whether the vSRX instance is a standalone VM or one of a cluster pair for high availability. The interface names and mappings in vSRX are shown in Table 1 and Table 2.

    Note the following:

    • In standalone mode:
      • fxp0 is the out-of-band management interface.
      • ge-0/0/0 is the first traffic (revenue) interface.
    • In cluster mode:
      • fxp0 is the out-of-band management interface.
      • em0 is the cluster control link for both nodes.
      • Any of the traffic interfaces can be specified as the fabric links, such as ge-0/0/0 for fab0 on node 0 and ge-7/0/0 for fab1 on node 1.

    Table 1 shows the interface names and mappings for a standalone vSRX VM.
