Understanding Junos Fusion Enterprise Software and Hardware Requirements

Aggregation Device Hardware Models

Table 1 lists the hardware platforms that are supported as aggregation devices for a Junos Fusion Enterprise. It also lists the supported satellite devices for each Junos OS Release supporting Junos Fusion Enterprise.

Maximum Number of Aggregation Devices

A Junos Fusion Enterprise supports one or two aggregation devices.

Cascade Ports

A cascade port is a port on an aggregation device that sends and receives control and network traffic from an attached satellite device.

Table 2 provides a list of line cards on an EX9200 switch that have interfaces that can be converted into cascade ports, and the initial Junos OS release that introduced cascade port support for interfaces on the line card.

Direct attach copper (DAC) cable connections cannot be configured as cascade ports.

Best Practice:

A cascade port is typically a 10-Gbps interface with an SFP+ transceiver or a 40-Gbps interface with a QSFP+ transceiver, although other interfaces on the aggregation device can be converted into a cascade port.

Satellite Device Hardware Models

Table 3 lists the EX2300 switches that are supported as satellite devices for a Junos Fusion Enterprise.

To convert an EX2300 switch from Junos OS to satellite software, the switch must be running Junos OS Release 15.1X53-D55 or later.

To find the required satellite software version, see Junos Fusion Hardware and Software Compatibility Matrices.

Table 4 lists the EX3400 hardware platforms that are supported as satellite devices for a Junos Fusion Enterprise.

To convert an EX3400 switch from Junos OS to satellite software, the switch must be running Junos OS Release 15.1X53-D55 or later.

To find the required satellite software version, see Junos Fusion Hardware and Software Compatibility Matrices.

Table 5 lists the EX4300 hardware platforms that are supported as satellite devices for a Junos Fusion Enterprise.

To convert an EX4300 switch from Junos OS to satellite software, the switch must be running Junos OS Release 14.1X53-D43 or later.

To find the required satellite software version, see Junos Fusion Hardware and Software Compatibility Matrices.

Table 6 lists the QFX5100 hardware platforms that are supported as satellite devices for a Junos Fusion Enterprise.

To convert a QFX5100 switch from Junos OS to satellite software, the switch must be running Junos OS Release 14.1X53-D43 or later.

To find the required satellite software version, see Junos Fusion Hardware and Software Compatibility Matrices.

Table 7 lists the EX4600 hardware platforms that are supported as satellite devices for a Junos Fusion Enterprise.

To convert an EX4600 switch from Junos OS to satellite software, the switch must be running Junos OS Release 14.1X53-D47 or later.

To find the required satellite software version, see Junos Fusion Hardware and Software Compatibility Matrices.

Note:

The EX4600-EM-8F and QFX-EM-4Q expansion modules are not supported in a Junos Fusion Enterprise.

Satellite Device Firmware Requirements

Table 8 lists the firmware requirements for satellite devices for a Junos Fusion Enterprise.

Satellite Device Software Requirements for Satellite Device Clustering

A standalone switch must be running the required satellite software before it can be added to a Junos Fusion Enterprise as a member of a satellite device cluster. A standalone switch running any version of satellite software below the minimum required version for that switch is not recognized by the aggregation device and cannot be added to a Junos Fusion Enterprise as a member of a satellite device cluster. To find the required satellite software version, see Junos Fusion Hardware and Software Compatibility Matrices.

If your switch is running a version of satellite or Junos OS software below the required minimum and you want to include the switch in a satellite device cluster, follow one of these procedures:

• if your switch is already cabled into a Junos Fusion and is able to upgrade to a version of satellite software that supports satellite device clustering, upgrade the satellite software on the switch before adding it to the satellite device cluster. See Configuring or Expanding a Junos Fusion Enterprise.

• If your switch is not cabled into a Junos Fusion, install a version of Junos OS that supports satellite device clustering using the procedure outlined in Installing Junos OS Software on a Standalone Device Running Satellite Software before installing the switch into the satellite device cluster.

  Once the switch is running a version of Junos OS that supports satellite device clustering, you can install the required satellite software version manually or as part of the satellite software installation that occurs as part of the procedure for adding a satellite device to a Junos Fusion Enterprise.

Satellite Software to Junos OS Conversion Requirements

A satellite device can be removed from a Junos Fusion Enterprise and reinserted into a network as a switch running Junos OS. See Removing a Satellite Device from a Junos Fusion.

A device running satellite software must be converted to a version of Junos OS that supports satellite device conversion. The minimum Junos OS versions that support satellite device conversion are provided in this document.

The following list provides additional information for converting each type of switch from satellite software to Junos OS.

• EX2300 and EX3400 switches:

  • EX2300 and EX3400 switches must be converted to Junos OS Release 15.1X53-D55 or later.

  • EX2300 and EX3400 switches cannot be converted from satellite software to Junos from an aggregation device. To convert the satellite software, remove the satellite device from the Junos Fusion Enterprise and perform the upgrade manually. See Installing Junos OS Software on a Standalone Device Running Satellite Software

  • The target Junos OS image must be a signed version of Junos OS. The text string -signed text must be n the Junos OS image filename when the image is downloaded from the Software Center.

• EX4300 switches:

  • EX4300 switches must be converted to Junos OS Release 14.1X53-D43 or later.

  • The target Junos OS image must be a signed version of Junos OS. The text string -signed text must be n the Junos OS image filename when the image is downloaded.

• QFX5100 switches:

  • The QFX5100 switch must be converted to Junos OS Release 14.1X53-D43 or later.

  • The target Junos OS image must be a Preboot eXecution Environment (PXE) version of Junos OS. The PXE version of Junos OS includes pxe in the package name when it is downloaded from the Software Center—for example, the PXE image for Junos OS Release 14.1X53-D43 is named install-media-pxe-qfx-5-14.1X53-D43.3-domestic-signed.tgz.

  • The target Junos OS image must be a signed version of Junos OS. The text string -signed text must be n the Junos OS image filename when the image is downloaded.

• EX4600 switches:

  • The EX4600 switch must be converted to Junos OS Release 14.1X53-D47 or later.

  • The target Junos OS image must be a Preboot eXecution Environment (PXE) version of Junos OS. The PXE version of Junos OS includes pxe in the package name when it is downloaded from the Software Center—for example, install-media-pxe-qfx-5-14.1X53-D47.<version>-domestic-signed.tgz.

  • The target Junos OS image must be a signed version of Junos OS. The text string -signed text must be n the Junos OS image filename when the image is downloaded.

Power over Ethernet Requirements for a Satellite Device

A satellite device must be running Power over Ethernet (PoE) controller software version as specified in Table 8.

To check the PoE controller software version, enter the show chassis firmware detail command and view the PoE firmware output.

For information on checking and upgrading the PoE controller software, see Upgrading the PoE Controller Software.

Note:

PoE is not supported for QFX5100 satellite devices.

Maximum Number of Satellite Devices or Extended Ports

A Junos Fusion Enterprise supports up to 128 satellite devices or 6,000 extended port access interfaces.
