Juniper SRX5400 Hardware Manual page 120

Each port on a MIC corresponds to a unique interface name in the CLI.
In the syntax of an interface name, a hyphen (-) separates the media type from the MPC number
(represented as an FPC in the CLI). The MPC slot number corresponds to the first number in the
interface. The second number in the interface corresponds to the logical PIC number. The last number
in the interface matches the port number on the MIC. Slashes (/) separate the MPC number from
the logical 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—Slot in which the MPC is installed in an SRX5400, SRX5600, or SRX5800 Services Gateway.
pic—Logical PIC on the MIC, numbered 0 when installed in the first slot or 2 when installed in the
second slot.
port—Port number.
Figure 47 on page 121 shows the port and interface numbering of an SRX-MIC-10XG-SFPP MIC
when it is installed in slot 0 of an MPC in slot 2 of an SRX5400, SRX5600, or SRX5800 Services
Gateway.

xe-2/0/1
The SRX-MIC-10XG-SFPP MIC contains one logical PIC, numbered PIC 0 in the CLI when inserted
in the first slot of the MPC or PIC 2 when inserted in the second slot of the MPC. Each logical PIC
contains 10 ports numbered 0 through 9.
The sample output of the show chassis fpc pic-status command displays two 10-port 10-Gigabit
Ethernet MICs with SFP+ — inserted into the slots of an MPC in slot 2.
The logical PICs of the two MICs— 10x 10GE SFP+ — are shown as PIC 0 and PIC 2.
