14 Dell EMC PowerEdge MX SmartFabric Configuration and Troubleshooting Guide
Full Switch mode
SmartFabric mode
username
spanning-tree
vlan
All switch interfaces are assigned to VLAN 1 by
default and are in the same Layer 2 bridge domain.
Layer 2 bridging is disabled by default. Interfaces
must join a bridge domain (VLAN) before being able
to forward frames.
All configurations changes are saved in the running
configuration by default. To display the current
configuration, use the
show running-
configuration
command.
Verify configuration changes using feature-specific
show commands, such as show interface and
show vlan, instead of show running-
configuration.
2.3 Changing operating modes
In both Full Switch and SmartFabric modes, all configuration changes you make using the OME-M GUI are
retained when you switch modes. Dell EMC recommends using the graphical user interface for switch
configuration in SmartFabric mode and the OS10EE CLI for switch configuration in Full Switch mode.
By default, a switch is in Full Switch mode. When that switch is added to a fabric, it automatically changes to
SmartFabric mode. When you change from Full Switch to SmartFabric mode, all Full Switch CLI
configurations are deleted except for the subset of CLI commands supported in SmartFabric mode.
To change a switch from SmartFabric to Full Switch mode, the fabric must be deleted. At that time, all
SmartFabric GUI configuration changes are deleted except for the configurations supported by the subset of
SmartFabric CLI commands (hostname, SNMP settings, etc.) and the changes you make to port interfaces,
except for admin state (shutdown/no shutdown), MTU, speed, and auto-negotiation mode.
There is no CLI command to switch between operating modes. The CLI command
show switch-
operating-mode
will display the currently configured operating mode of the switch. This information is
also available on the switch landing page in the OME-Modular GUI.
2.4 MX9116n Fabric Switching Engine (FSE): virtual ports
A virtual port is a logical switch port that connects to a downstream server and has no physical hardware
location on the switch. Virtual ports are created when an MX9116n Fabric Switching Engine (FSE) on-boards
an MX7116n Fabric Expander Module (FEM). The onboarding process consists of discovery and
configuration.
NOTE: If the servers in the chassis have dual-port NICs, only QSFP28-DD port 1 on the FEM needs to be
connected. Do not connect QSFP28-DD port 2.
To verify the auto-discovered Fabric Expanders, enter the show discovered-expanders command
OS10# show discovered-expanders
