Understanding Interface Naming Conventions

 

The EX Series, QFX Series, NFX Series, OCX1100, QFabric System, and EX4600 devices use a naming convention for defining the interfaces that are similar to that of other platforms running under Juniper Networks Junos OS. This topic provides brief information about the naming conventions used for interfaces on the QFX Series and on EX4600 switches.

This topic describes:

Physical Part of an Interface Name for EX Series

Network interfaces in Junos OS are specified as follows:

type-fpc / pic / port

EX Series switches apply this convention as follows:

  • type—EX Series interfaces use the following media types:

    • ge—Gigabit Ethernet interface

    • xe—10 Gigabit Ethernet interface

    • et—40 Gigabit Ethernet interface

  • fpc—Flexible PIC Concentrator. EX Series interfaces use the following convention for the FPC number in interface names:

    • On an EX2200 switch, an EX3200 switch, a standalone EX3300 switch, a standalone EX4200 switch, a standalone EX4300 switch, a standalone EX4500, and a standalone EX4550 switch, FPC refers to the switch itself. The FPC number is 0 by default on these switches.

    • On an EX3300 Virtual Chassis, an EX4200 Virtual Chassis, an EX4300 Virtual Chassis, an EX4500 Virtual Chassis, an EX4550 Virtual Chassis, or a mixed Virtual Chassis, the FPC number indicates the member ID of the switch in the Virtual Chassis.

    • On an EX6200 switch and a standalone EX8200 switch, the FPC number indicates the slot number of the line card that contains the physical interface. On an EX6200 switch, the FPC number also indicates the slot number of the Switch Fabric and Routing Engine (SRE) module that contains the uplink port.

    • On an EX8200 Virtual Chassis, the FPC number indicates the slot number of the line card on the Virtual Chassis. The line card slots on Virtual Chassis member 0 are numbered 0 through 15; on member 1, they are numbered 16 through 31, and so on.

  • pic—EX Series interfaces use the following convention for the PIC (Physical Interface Card) number in interface names:

    • On EX2200, EX3200, EX3300, EX4200, EX4500 switch, and EX4550 switches, the PIC number is 0 for all built-in interfaces (interfaces that are not uplink ports).

    • On EX2200, EX3200, EX3300, and EX4200 switches, the PIC number is 1 for uplink ports.

    • On EX4300 switches, the PIC number is 0 for built-in network ports, 1 for built-in QSFP+ ports (located on the rear panel of the switch), and 2 for uplink module ports.

    • On EX4500 switches, the PIC number is 1 for ports on the left-hand uplink module and 2 for ports on the right-hand uplink module.

    • On EX4550 switches, the PIC number is 1 for ports in the expansion module or Virtual Chassis module installed in the module slot on the front panel of the switch and 2 for those in the expansion module or Virtual Chassis module installed in the module slot on the rear panel of the switch.

    • On EX6200 and EX8200 switches, the PIC number is always 0.

  • port—EX Series interfaces use the following convention for port numbers:

    • On EX2200, EX3200, EX3300, EX4200, EX4300, EX4500, and EX4550 switches, built-in network ports are numbered from left to right. On models that have two rows of ports, the ports on the top row start with 0 followed by the remaining even-numbered ports, and the ports on the bottom row start with 1 followed by the remaining odd-numbered ports.

    • Uplink ports in EX2200, EX3200, EX3300, EX4200, EX4300, EX4500, and EX4550 switches are labeled from left to right, starting with 0.

    • On EX6200 and EX8200 switches, the network ports are numbered from left to right on each line card. On line cards that have two rows of ports, the ports on the top row start with 0 followed by the remaining even-numbered ports, and the ports on the bottom row start with 1 followed by the remaining odd-numbered ports.

    • Uplink ports on an SRE module in an EX6200 switch are labeled from left to right, starting with 0.

Logical Part of an Interface Name for EX Series

The logical unit part of the interface name corresponds to the logical unit number, which can be a number from 0 through 16384. In the virtual part of the name, a period (.) separates the port and logical unit numbers: type-fpc/pic/port.logical-unit-number. For example, if you issue the show ethernet-switching interfaces command on a system with a default VLAN, the resulting display shows the logical interfaces associated with the VLAN:

Wildcard Characters in Interface Names for EX Series

In the show interfaces and clear interfaces commands, you can use wildcard characters in the interface-name option to specify groups of interface names without having to type each name individually. You must enclose all wildcard characters except the asterisk (*) in quotation marks (" ").

Physical Part of an Interface Name for QFX series, NFX Series, EX4600, QFabric System

Interfaces in Junos OS are specified as follows:

device-name:type-fpc/pic/port

The convention is as follows (and platform support depends on the Junos OS release in your installation):

  • device-name—(QFabric systems only) The device-name is either the serial number or the alias of the QFabric system component, such as a Node device, Interconnect device, or QFabric infrastructure. The name can contain a maximum of 128 characters and cannot contain any colons.

  • type—The QFX Series and EX4600 device interfaces use the following media types:

    • fc—Fibre Channel interface

    • ge—Gigabit Ethernet interface

    • xe—10-Gigabit Ethernet interface

    • sxe—10-Gigabit Service interface. sxe is an internal interface and user must not configure this interface. It supports L2 and L3 configurations like VLANs and IP address.

    • xle—40-Gigabit Ethernet interface (QFX3500, QFX3600, and QFX5100 switches running a QFabric software package)

    • et—40-Gigabit Ethernet interface (QFX3500, QFX3600, QFX5100, QFX5200, QFX10000, and EX4600 switches running Enhanced Layer 2 Software)

    • et—100-Gigabit Ethernet interface (QFX5200 and QFX10000 switches running Enhanced Layer 2 Software)

    • fte—40-Gigabit data plane uplink interface (QFX3500, QFX3600, and QFX5100 switches running a QFabric software package)

    • me—Management interface

    • em—Management interface on QFX5100 and EX4600 switches.

  • fpc—Flexible PIC Concentrator. QFX Series interfaces use the following convention for the FPC number in interface names:

    • On QFX3500, QFX3600, QFX5100 devices running a QFabric software package, and QFX10002 switches, the FPC number is always 0.

      The FPC number indicates the slot number of the line card that contains the physical interface.

    • On QFX3500, QFX3600, QFX5100, QFX5200, EX4600, QFX10002, QFX10008, and QFX10016 switches running Enhanced Layer 2 Software, the member ID of a member in a Virtual Chassis determines the FPC number.

      Note

      Every member in a Virtual Chassis must have a unique member ID, otherwise the Virtual Chassis will not be created.

    • On standalone QFX5100, EX4600, and QFX10002 switches, the FPC number is always 0.

  • pic—QFX Series and EX4600 device interfaces use the following convention for the PIC (Physical Interface Card) number in interface names:

      The QFX10000-36Q line card consists of 36 quad small form-factor pluggable plus (QSFP+) ports that support 40-Gigabit Ethernet optical transceivers. Out of these 36 ports, 12 ports are QSFP28 capable. The QSFP+ ports are dual speed and can support either 40-Gigabit or 100-Gigabit Ethernet optical transceivers. The line card can support 10-Gigabit Ethernet by channelizing the 40-Gigabit ports. Channelization is supported on fiber break-out cable using standard structured cabling techniques.

      With 100-Gigabit Ethernet using QSFP28 optical transceivers, when a QSFP28 transceiver is inserted into the ports marked with a fine black line underneath the socket and the port is configured for 100-Gigabit Ethernet, the two adjacent ports are disabled and the QSFP28 socket is enabled for 100-Gigabit Ethernet.

      You can use 40-Gigabit Ethernet using QSFP+ optical transceivers.

      With 10-Gigabit Ethernet using breakout cabling and attached optical transceivers, when configured for channelization, the system converts the 40-Gigabit Ethernet port into 4 independent 10-Gigabit Ethernet ports.

      Any of the 36 ports 0 through 35 can be configured as either uplink or access ports.

      Each of the 12 QSFP28 ports supports:

      • 100-Gigabit Ethernet QSFP28 transceivers

      • 40-Gigabit Ethernet QSFP+ transceivers

      Each of the 36 QSFP+ ports supports:

      • 40-Gigabit Ethernet QSFP+ transceivers

      • Access ports

        You can use 40-Gigabit Ethernet QSFP+ transceivers in any downstream port.

      • Uplink ports

        You can configure all the QSFP+ ports as uplinks.

      Every second and sixth port in a 6XQSFP cage on a QFX10000-36Q supports 100-Gigabit Ethernet using QSFP28 transceivers. These 100-Gigabit Ethernet ports work either as 100-Gigabit Ethernet or as 40-Gigabit Ethernet, but are recognized as 40-Gigabit Ethernet by default. When a 40-Gigabit Ethernet transceiver is inserted into a 100-Gigabit Ethernet port, the port recognizes the 40-Gigabit Ethernet port speed. When a 100-Gigabit Ethernet transceiver is inserted into the port and enabled in the CLI, the port recognizes the 100-Gigabit Ethernet speed and disables two adjacent 40-Gigabit Ethernet ports. You can also use an 100-Gigabit Ethernet transceiver and run it at 40-Gigabit Ethernet by using the CLI to set the port speed to 40-Gigabit Ethernet.

      The 40-Gigabit Ethernet ports can operate independently, be channelized into four 10-Gigabit Ethernet ports, or bundled with the next two consecutive ports and channelized into twelve 10-Gigabit Ethernet ports as a port range. Only the first and fourth port in each 6XQSFP cage are available to channelize a port range. The port range must be configured using the set chassis fpc pic port channel-speed command. For example, to channelize the first switch port, use the set chassis fpc 0 pic 0port 1channel-speed 10g command.

    QFX10016 with Line Card QFX10000-30C and QFX10000-30C-M (ELS)

    The QFX10000-30C and QFX10000-30C-M line cards consist of thirty 28-Gbps QSFP+ Pluggable Solution (QSFP28) cages that support either 40-Gigabit Ethernet or 100-Gigabit Ethernet optical transceivers. The QFX10000-30C and QFX10000-30C-M ports auto detect the type of transceiver installed and set the configuration to the appropriate speed.

    Each QSFP28 socket supports:

    • 100-Gigabit Ethernet using QSFP28 optical transceivers. When a QSFP28 transceiver is inserted into any of the ports, the QSFP28 socket is enabled for 100-Gigabit Ethernet.

    • 40-Gigabit Ethernet using QSFP+ optical transceivers. When a QSFP+ transceiver is inserted into any of the ports, the QSFP+ socket is enabled for 40-Gigabit.

      Any of the 30 ports 0 through 29 can be configured as either uplink or access ports, and of the 30 QSFP28 ports supports:

      • 100-Gigabit Ethernet QSFP28 transceivers

      • 40-Gigabit Ethernet QSFP+ transceivers

Logical Part of an Interface Name on a Switch Running QFabric Software Package for QFX series, NFX Series, EX4600, QFabric System

The logical unit part of the interface name corresponds to the logical unit number, which can be a number from 0 through 16384. In the virtual part of the name, a period (.) separates the port and logical unit numbers: device-name (QFabric systems only): type-fpc/pic/port.logical-unit-number. For example, if you issue the show ethernet-switching interfaces command on a system with a default VLAN, the resulting display shows the logical interfaces associated with the VLAN:

When you configure aggregated Ethernet interfaces, you configure a logical interface, which is called a bundle or a LAG. Each LAG can include up to eight Ethernet interfaces, depending on the switch model.

Logical Part of a Channelized Interface Name on a Switch Running Enhanced Layer 2 Software for QFX series, NFX Series, EX4600, QFabric System

Channelizing enables you to configure four 10-Gigabit Ethernet interfaces from a 40-Gigabit Ethernet QSFP+ interface. By default, a 40-Gigabit Ethernet QSFP+ interface is named et-fpc/pic/port. The resulting 10-Gigabit Ethernet interfaces appear in the following format: xe-fpc/pic/port:channel, where channel can be a value of 0 through 3.

For example, if an et interface named et-0/0/3 is channelized to four 10-Gigabit Ethernet interfaces, the resulting 10-Gigabit Ethernet interface names will be xe-0/0/3:0, xe-0/0/3:1, xe-0/0/3:2, and xe-0/0/3:3:

Wildcard Characters in Interface Names for QFX series, NFX Series, EX4600, QFabric System

In the show interfaces and clear interfaces commands, you can use wildcard characters in the interface-name option to specify groups of interface names without having to type each name individually. You must enclose all wildcard characters except the asterisk (*) in quotation marks (" ").

Physical Part of an Interface Name for OCX1100

Interfaces in Junos OS are specified as follows:

type-fpc/pic/port

The convention is as follows:

  • type—The OCX Series device interfaces use the following media types:

    • xe—10-Gigabit Ethernet interface

    • et—40-Gigabit Ethernet interface

    • em—Management interface

  • fpc—Flexible PIC Concentrator. OCX Series interfaces use the following convention for the FPC number in interface names:

    • On standalone OCX Series switches, the FPC number is always 0.

      The FPC number indicates the slot number of the line card that contains the physical interface.

  • pic—The OCX Series interfaces use the following convention for the PIC (Physical Interface Card) number in interface names:

    • PIC 0 provides six 40-Gbps QSFP+ ports and 48 10-Gigabit Ethernet interfaces.

  • port—Interfaces use the following convention for port numbers:

    • PIC 0 can support 48 network access ports (10-Gigabit Ethernet ports) labeled 1 through 48 and 6 40-Gbps QSFP+ ports labeled 49 through 54.
