Analyze Why Changing the MTU Does Not Correctly Set the Link Property (Oracle Solaris)

The dladm command might display this message:

# dladm: warning: cannot set link property 'mtu' on 'net0': link busy

The message indicates that some objects defined on the link might need to be removed or plumbed down.

1. Disable any network objects defined over the link.

   Depending on your configuration, you might need to use the dladm delete-vlan command or the dladm delete-vnics command to disable objects. For instructions, refer to How to Delete a VNIC in Managing Network Virtualization and Network Resources in Oracle Solaris 11.3 and Deleting a VLAN in Managing Network Datalinks in Oracle Solaris 11.3.

2. Change the MTU.

   # dladm set-linkprop -p mtu=9706 net0
