Managing Fusion Fabrics

With Junos Fusion technology, network administrators can reduce network complexity and operational expenses by collapsing underlying network elements into a single, logical point of management using QFX Series and EX Series switches running the Junos operating system. You can create and provision Junos Fusion fabrics using Network Director. The Manage Fusion Fabrics page displays the status and details of all fusion fabrics that are created using Network Director.

To open the Manage Fusion Fabrics page:

Under Views, select one of these options: Logical View, Location View, Device View, or Custom Group View.

Tip:
Do not select Dashboard View or Topology View.
Click in the Network Director banner.
From the Tasks menu, select Network Builder > Manage Fusion Fabrics.

The Manage Fusion Fabrics page opens. Table 1 describes the fields that are displayed in the Manage Fusion Fabrics page.

Edit Aggregation Device Details

To edit the aggregation device details:

Open the Aggregation Devices tab in the Edit Fusion Fabric page to edit the aggregation device details. You can add cascade ports or delete cascade ports from an aggregation device. To do this, select an aggregation device from the table. Network Director displays the cascade ports that are part of the selected aggregation device in the port details table.
To add new cascade ports to the aggregation device, click Add Ports. The Select Ports window opens. Click an FPC and select the ports that you want to include. When you have added the ports, click Add.
To delete a cascade port, select a port from the port details table and click Remove.
Note:
In a multihome Junos Fusion fabric, if you remove a cascade port from one aggregation device, Network Director initiates a two-step commit process on both the aggregation devices. If one of the aggregation device is out-of-sync or is not reachable, the port is not deleted.

Edit Satellite Device Details

To edit the satellite device details:

Open the Satellite Devices tab in the Edit Fusion Fabric page to edit the satellite device details.
You can perform the following operations on the satellite devices in the Edit Fusion Fabric page:
- change the alias name for the satellite device. See Step 2.
- remove a satellite device. See Step 3.
In a multi-home setup, the configuration for a satellite device exists on both the aggregation devices. In such a topology, the alias name of the satellite device should be identical on both the aggregation devices. If the alias names of a satellite device does not match, you need to edit the alias name to be identical on both the aggregation devices. To edit the alias name of a satellite device:
1. Select the FPC slot number.
2. Click the alias name in the column Alias Name.
3. Type the new alias name and then click Save.
  Network Director displays a warning message Alias name for AD1 and AD2 will be same after the edit.
4. Click OK.
  The alias name of the satellite device is now identical on both the aggregation devices.
To remove a satellite device from the fusion fabric, select the device and click Remove.
Note:
Replacing a satellite device that has no MAC address or serial number binding to the FPC slot on the aggregation device is plug-and-play. Replace the satellite device in your Junos Fusion topology and Network Director takes care of all the remaining configurations. This is irrespective of whether the device is a standalone device or a member of a satellite cluster. However, if there is a MAC address or serial number binding between the satellite device and the FPC slot on the aggregation device, you must run some commands from the CLI of the aggregation device to replace the satellite device. For more details, see Replace Aggregation Device or Satellite Device in Junos Fusion.

Enable Uplink Failure Detection

To enable update failure detection:

Click the Settings tab in the Edit Fusion Fabric page.
Select Uplink Failure Detection check box corresponding to the device to enable uplink failure detection on a Junos Fusion.
Enabling uplink failure detection on a satellite devices detects link failures on the uplink interfaces used to connect to aggregation devices. When uplink failure detection detects uplink failure on a satellite device, all of the device’s extended ports (which connect to host devices) are shut down.

You can also view the ICL and ICCP settings for a multihome Junos Fusion Enterprise fabric.

View the Cabling Plan

To download the cabling plan for the Junos Fusion fabric, click Download Cabling Plan from the Action field corresponding to a fabric. Network Director generates and downloads the cabling plan as a PDF file.

View Fabric Connectivity

After you have set up and deployed Junos Fusion devices in Network Director, you can pictorially view the physical connectivity between the various devices in the fabric. This page displays the devices and their physical connectivity in the spine-and-leaf topology.

To view the connectivity between the Junos Fusion devices:

Do one of the following:
- From the Manage Fusions page, click View Topology in the Actions field.
- While in the Logical, Location, Device, or Custom View, select the Junos Fusion fabric for which you want to view the connectivity details from the View pane and click Connectivity > View Fabric Connectivity from the Tasks pane.

Replace Aggregation Device or Satellite Device in Junos Fusion

Network Director enables you to replace faulty or non-responsive aggregation devices in your Junos Fusion fabric by using the Replace functionality. You can replace an aggregation device in a dual home Junos Fusion by selecting the device that you want to remove and by specifying the serial number or the MAC address of the replacement device.

Replacing a satellite device that has no MAC address or serial number binding to the FPC slot on the aggregation device is plug-and-play. Replace the satellite device in your Junos Fusion topology and Network Director takes care of all the remaining configurations. This is irrespective of whether the device is a standalone device or a member of a satellite cluster. However, if there is a MAC address or serial number binding between the satellite device and the FPC slot on the aggregation device, you must run some commands from the CLI of the aggregation device to replace the satellite device.

This topic describes the steps that you must perform to replace an aggregation device or a satellite device from the a Junos Fusion fabric.

To replace aggregation device or satellite device:

From the Manage Fusions page, select a fusion fabric for which you want to replace an aggregation and click Replace. The Replace Fusion Fabric page opens.
To replace an aggregation device, select the aggregation device that you want to replace and click Replace.
Enter the MAC address or the serial number of the new aggregation device.
Do one of the following to replace a satellite device that has a MAC address or serial number binding to the FPC slot of the aggregation device:
- If the satellite device is a standalone device, log in to the CLI of the aggregation device and execute the following commands:
  
  user@aggregation-device# set chassis satellite-management fpc fpc-id system-id MAC-address-of-the-device | Serial-number -of-the-deviceuser@aggregation-device# Commit
- If the satellite device is part of a cluster, log in to the CLI of the aggregation device and execute the following commands:
