If you configure the MTU parameter of a network interface for an
ethernet bridge and then power off the Oracle VM Server for SPARC, the MTU used
by the bridge after the boot can be reset to the default value of
1500
instead of the configured value.
Workaround: When the interface used for the bridge is persistently plumbed in the primary domain, the bridge is created with the appropriate MTU parameter after the server power off and reboot. Use the ipadm(1M) command to persistently plumb a network interface, as in the following example:
# ipadm create-ip net0
