get rb1100AHx2 and set MTU over 9000, seriously.
just note that you need to have supporting hardware elsewhere to use jumbo frames.

Hi Janisk...
you mean we set the value on the ethx > general > mtu?

hi, appreciated it.
got a question that, if i ping from the windows command prompt.

if i issue the following command...
ping 192.168.88.1 -t -l 5000, does it mean i am pinging with 5000 size of packet?

if not, how we going to check the packet size flow to the routerboard?

thanks

It means you are pinging with 5000 bytes of just ICMP payload. Add 8 bytes for the ICMP header, and 20 bytes for the IP header and that'll put you at 5028 bytes. This value of 5028 should not exceed the MTU value set on the router otherwise the packet will not pass.

ping -t -l 5000 -f 192.168.88.1
