interfaces bonding <dpFbondx> mtu <mtu>
Specifies the MTU for an Ethernet link bond group.
The MTU of the first Ethernet link added to the group is used.
- dpFbondx
- The identifier for a bond group. The identifier ranges from dp0bond0 through dp0bond99.
- mtu
- The MTU, in octets, for the interface as a whole, including any logical interfaces that are configured for it. The MTU ranges from 68 to 9000.

Use this command to set the maximum transmission unit (MTU) for an Ethernet link bond group. The MTU is also applied to any vifs that are defined for the bonding interface.
Changing the MTU changes the MTU on the Ethernet links within the bond. Also, explicitly changing the MTU of the Ethernet links within the bond (by configuring the individual links) is not allowed.
During forwarding, IPv4 packets larger than the MTU are fragmented unless the DF bit is set. In that case, the packets are dropped and an ICMP “Packet too big” message is returned to the sender.
Use the set form of this command to set the MTU of a bond group.
Use the delete form of this command to restore the default MTU, which is the MTU of the first Ethernet link added to the group, and disable fragmentation.
Use the show form of this command to display the MTU for a bond group.
