ONTAP System Manager 9.8 to 9.11.1

Answer

  • ONTAP System Manager between ONTAP 9.8 and ONTAP 9.11.1 does not provide the ability to change the maximum transmission unit (MTU) size for a network port.
    • System Manager added configuration of MTU values in a broadcast domain in 9.12.0 and later.
  • Run the network port broadcast-domain modify CLI command to modify the MTU value (in bytes) for a network port.
    Note: The port's MTU is determined by its broadcast domain. Changing the MTU value will affect all ports in the broadcast domain:

network port broadcast-domain modify -ipspace <IPspace> -broadcast-domain <broadcast-domain> -mtu <value>
