On Gigabit Ethernet ePIMs of J4350 and J6350 Services
Routers, you can configure a maximum transmission unit (MTU) size
of only 9018 bytes even though the CLI indicates that you can configure
an MTU of up to 9192 bytes. If you configure an MTU greater than 9018
bytes, the router does not accept the configuration and generates
a system log error message similar to the following:
/kernel: ge-0/0/0: Illegal media change. MTU invalid: 9192.
Max MTU supported on this PIC: 9018
