The following figure shows a topology using a pair of Dell PowerSwitch S5232F-ON upstream switches, but any SmartFabric OS10 switches can be used. This section details configuration of the S5232F-ON with Ethernet - No Spanning Tree uplink as well as validation of the S5232F-ON configuration. It also includes instructions on how to configure SmartFabric.
Configure SmartFabric
Perform the following steps to configure SmartFabric:
- Physically cable the MX9116n FSE to the S5232F-ON upstream switch. Make sure that chassis are in a Multi-Chassis Management group. For instructions, find the relevant version of the User Guide in the OME-M and OS10 compatibility and documentation table.
- Define VLANs to use in the Fabric. For instructions, see Define VLANs.
- Create the SmartFabric as per instructions in Create the SmartFabric.
- Configure uplink port speed or breakout. For more instructions, see Configuring port speed and breakout.
- After the SmartFabric is created, create the Ethernet - No Spanning Tree uplink. See Create Ethernet – No Spanning Tree uplink for more information.
- Set MX I/O modules global spanning tree configurations to Rapid Spanning Tree Protocol (RSTP).
- Create and deploy the appropriate server templates to the compute sleds. See Server Deployment for more information.
Dell PowerSwitch S5232F-ON configuration
This section outlines the configuration commands issued to the Dell PowerSwitch S5232F-ON switches with Ethernet - No Spanning Tree uplink connected from MX9116n FSE to S5232F-ON. The switches start with their factory default settings as indicated in the Reset SmartFabric OS10 switch to factory defaults section.
There are four steps to configure the S5232F-ON upstream switches:
- Set the switch hostname and management IP address. Enable spanning-tree mode as RSTP.
- Configure the VLT between the switches.
- Configure the VLANs.
- Configure the port channels to connect to the MX switches.
Use the following commands to set the hostname, and to configure the OOB management interface and default gateway.

Configure the VLT between switches using the following commands. VLT configuration involves setting a discovery interface range and discovering the VLT peer in the VLTi. The vlt-domain command configures the peer leaf-2 switch as a back-up destination.
S5232-ON Leaf 1 | S5232-ON Leaf 2 |

Configure the required VLANs on each switch. In this deployment example, the VLAN used is VLAN 10 and the Untagged VLAN used is VLAN 1.
S5232-ON Leaf 1 | S5232-ON Leaf 2 |
| |
Configure the port channels that connect to the downstream switches. The LACP protocol is used to create the dynamic LAG. Trunk ports allow tagged VLANs to traverse the trunk link. In this example, the trunk is configured to allow VLAN 10. Disable the spanning tree on port channels and run the commands related to Ethernet - No Spanning Tree uplinks as mentioned in the following.

Dell PowerSwitch S5232-ON validation
This section contains validation commands for the Dell PowerSwitch S5232-ON leaf switches.
show vlt
The show vlt command
validates the VLT configuration status when the VLTi Link Status is up. The role of one switch in the VLT pair is primary, and its peer switch (not shown) is assigned the secondary role.

connect to the two MX9116n FSEs, C160A2
and C140A1
. The remaining links, ethernet1/1/29

show smartfabric uplinks
The show smartfabric uplinks
command is used to verify the uplinks configured across the nodes in the fabric. This displays name, description, id, media type, native vlan, configured interfaces, and network profile associated with fabric. Run this command on MX9116n FSE. The following output shows that the uplink created is an Ethernet - No Spanning Tree uplink.
