Operational Modes

The FN I/O Module supports four operational modes. Select the operational mode that meets your deployment needs. To enable a new operational mode, reload the switch.

  • Standalone mode — stack-unit unit iom-mode standalone . This is the default mode for IOA. It is fully automated zero-touch mode that allows you to configure VLAN memberships. (Manageable through CMC also)
  • Programmable MUX mode (PMUX) — stack-unit unit iom-mode programmable-mux . Select this mode to configure PMUX mode CLI commands.
  • Stacking mode — stack-unit unit iom-mode stacking. Select this mode to stack up to six IOA stack units as a single logical switch. The stack units can be in the same or on different chassis. This is a low-touch mode where all configuration except VLAN membership is automated. To enable VLAN, you must configure it. In this operational mode, ports 9 and 10 are dedicated to stacking.
  • Virtual Link Trunking mode (VLT) — stack-unit unit iom-mode vlt . Select this mode to multi-home server interfaces to different IOA modules. This is a low-touch mode where all configuration except VLAN membership is automated. To enable VLAN, you must configure it. In this mode, ports 9 is configured as VLT interconnect.
  • Full Switch mode — stack-unit unit iom-mode full-switch. The full switch mode provides Layer 2 / Layer 3 functionalities on the Dell FX2 chassis. All the commands and configurations supported on the MXL is available in full-switch mode.
