Port and Interface Numbering

Each port on the services gateway corresponds to a unique interface name in the CLI. The four Chassis cluster (HA) ports (referred to as PIC 0 ports of FPC 0), four 40/100-Gigabit Ethernet QSFP28 (quad small form-factor pluggable) ports (referred to as PIC 0 ports of FPC 1), and eight 1/10-Gigabit Ethernet SFP+ ports (referred to as PIC 1 ports of FPC 1). Figure 6 shows the SRX4600 Interface Port numbering.

In the syntax of an interface name, a hyphen (-) separates the media type from the FPC slot number (represented as an FPC in the CLI). The FPC slot number corresponds to the first number in the interface. The second number in the interface corresponds to the PIC number. The last number in the interface matches the port number on the PIC. Slashes (/) separate the FPC number from the PIC number and port number:

type-fpc/pic/port

  • type—Media type, which identifies the network device. For example:

    • ge—Gigabit Ethernet interface

    • so—SONET/SDH interface

    • xe—10-Gigabit Ethernet interface

    For a complete list of media types, see Interface Naming Overview.

  • fpc—FPC number, 0 or 1.

  • pic—PIC number, 0 or 1.

  • port—Port number.

Figure 6: SRX4600 Interface Port Numbering
SRX4600 Interface
Port Numbering

The maximum capacity of an SRX4600 Services Gateway is 400 Gbps, which cannot be oversubscribed. In SRX4600, the network ports are available in two groups (referred to as PICs), with restrictions around the number and type of ports that can be configured without over-subscribtion.
