Configuring Gigabit Ethernet Physical Interface Modules

 

Small form-factor pluggables (SFPs) are hot-pluggable modular interface transceivers for Gigabit and Fast Ethernet connections. The 1-Port Gigabit Ethernet SFP Mini-PIM interfaces a single Gigabit Ethernet device or a network. The below topics discuss the overview and configuration of 1-Port Gigabit Ethernet SFP Mini-PIM interface, overview and configuration of 2-Port 10-GE XPIM and overview and configuration of 8-Port GE SFP XPIMs.

Understanding the 1-Port Gigabit Ethernet SFP Mini-PIM

Small form-factor pluggables (SFPs) are hot-pluggable modular interface transceivers for Gigabit and Fast Ethernet connections. Gigabit Ethernet SFP Mini-PIMs can be used in copper and optical environments to provide maximum flexibility when upgrading from an existing infrastructure to Metro Ethernet.

The 1-Port Gigabit Ethernet SFP Mini-PIM interfaces a single Gigabit Ethernet device or a network. It supports a variety of transceivers with data speeds of 10-Mbps/100-Mbps/1-Gbps with extended LAN or WAN connectivity.

Transceivers are hot-swappable.

This topic includes the following sections:

Supported Features

The following features are supported on the 1-Port Gigabit Ethernet SFP Mini-PIM:

  • 10-Mbps/100-Mbps/1-Gbps link speed

  • Half-duplex/full-duplex support

  • Autonegotiation

  • Encapsulations

  • Maximum transmission unit (MTU) size of 1514 bytes (default) and 9010 bytes (jumbo frames)

  • Loopback

  • Transceivers are hot-swappable

Interface Names and Settings

The following format is used to represent the 1-Port Gigabit Ethernet SFP Mini-PIM interface names:

type-fpc/pic/port

Where:

  • type—Media type (ge)

  • fpc—Number of the Flexible PIC Concentrator (FPC) card on which the physical interface is located

  • pic—Number of the PIC on which the physical interface is located (0)

  • port—Specific port on a PIC (0)

Examples: ge-1/0/0 and ge-2/0/0

By default, the interfaces on the ports on the uplink module installed on the device are enabled. You can also specify the MTU size for the Gigabit Ethernet interface. Junos OS supports values from 256 through 9010. The default MTU size for Gigabit Ethernet interfaces is 1514.

Available Link Speeds and Modes

The 1-Port Gigabit Ethernet SFP Mini-PIM supports the following link speeds:

  • 10m—Sets the link speed to 10 Mbps.

  • 100m—Sets the link speed to 100 Mbps.

  • 1g—Sets the link speed to 1 Gbps.

The 1-Port Gigabit Ethernet SFP Mini-PIM supports the following link modes:

  • Full-duplex—Allows bidirectional communication at a given point in time.

  • Half-duplex—Allows single directional communication at a given point in time.

Link Settings

The 1-Port Gigabit Ethernet SFP Mini-PIM includes the following link settings:

  • auto-negotiation—Enables autonegotiation of link mode and speed.

    Note

    By default, autonegotiation is enabled. To disable autonegotiation, use set gigether-options no-autonegotiation

    We recommend enabling autonegotiation.

  • loopback—Enables loopback.

  • no-auto-negotiation—Disables autonegotiation of link mode and speed.

  • no-loopback—Disables loopback.

By default a link speed of 1 Gbps in full-duplex mode is supported.

Note

On SRX340 High Memory devices, traffic might stop between the SRX340 device and the Cisco switch due to link mode mismatch. We recommend setting the same value to the autonegotiation parameters on both ends.

Note

On SRX300 devices, the link goes down when you upgrade FPGA on 1-Port Gigabit Ethernet SFP mini-PIM. As a workaround, run the restart fpc command and restart the FPC.

Understanding the 2-Port 10-Gigabit Ethernet XPIM

The 10-Gigabit Ethernet (also known as 10GBASE-T or IEEE 802.3an) is a telecommunication technology that offers data speeds up to 10 billion bits per second over unshielded or shielded twisted pair cables.

The 2-Port 10-Gigabit Ethernet Physical Interface Module (XPIM) is a 2 x 10GBASE-T / SFP+ XPIM line card. (SFP+ is a fiber optic transceiver module designed for 10-Gigabit Ethernet and 8.5 Gbps-fiber channel systems.) The 2-Port 10-Gigabit Ethernet XPIM provides a front-end interface connection that includes the following ports:

  • 2 X copper ports. The copper ports support 10GBASE-T running with CAT6A or CAT7 Ethernet cable for up to 100 meters.

  • 2 X fiber (SFP+) ports. The fiber ports support SFP+ multiple 10G modules.

The 2-Port 10-Gigabit Ethernet XPIM provides interconnects for LANs, WANs, and metropolitan area networks (MANs). The XPIM provides multiple service levels (1-Gigabit Ethernet to 10-Gigabit Ethernet in increments) and a single connection option for a wide range of customer needs and applications.

Note

By default, the 2-Port 10-Gigabit Ethernet XPIM ports comes up in fiber mode, while autonegotiation is not supported.

type-fpc/pic/port

Where:

  • type — Media type (xe)

  • fpc — Number of the Flexible PIC Concentrator (FPC) card on which the physical interface is located

The default MTU for Gigabit Ethernet interfaces is 1514.

Copper and Fiber Operating Modes

On the 2-Port 10-Gigabit Ethernet XPIM, one copper port and one fiber port is grouped together as port 0, and another copper port and fiber port are grouped as port 1. Only two ports can be active at the same time (one port from port 0 and another port from port 1).

The 2-Port 10-Gigabit Ethernet XPIM can be configured to operate in two copper mode, two fiber mode, or mixed mode (one copper and one fiber). In mixed mode, the two ports should be from different port groups (one port from port 1 and the other from port 2).

Link Speeds

The 2-Port 10-Gigabit Ethernet XPIM ports support the following link speeds for copper and fiber:

  • Copper—10/100/1000 Mbps or 10Gbps (full duplex). Half-duplex is only for 10/100 Mbps.

  • Fiber—1000 Mbps or 10 Gbps (full duplex). Half-duplex mode is not supported.

To set the link speeds, use the following options:

  • 10m—Sets the link speed to 10 Mbps.

  • 10g—Sets the link speed to 10 Gbps.

  • 100m—Sets the link speed to 100 Mbps.

  • 1g—Sets the link speed to 1 Gbps.

Link Settings

The 2-Port 10-Gigabit Ethernet XPIM includes the following link settings:

By default, flow control is enabled on all ports, a link speed of 10 Gbps in full duplex is supported, autonegotiation is disabled on the fiber ports, and autonegotiation is enabled on copper ports.

Note

Autonegotiation is not supported when the 2-Port 10-Gigabit Ethernet XPIM is operating in fiber mode at a link speed of 10 Gbps.
