Jumbo Frame

What is "BABY GIANT FRAME " and "JUMPO FRAME" in TCP/IP Networking ?

• The maximum size of an Ethernet frame should not exceed 1500 bytes + 18 bytes of Header
• If the size of an ethernet frame is more than 1518 bytes, then it is called as Baby Giant Frame or Jumpo frame.
• 1519 to 1600 bytes means Baby Giant Frame
• 1601 to 9216 bytes means Jumpo Frame.
• Mainly, the Switches are handling the Ethernet Frames.
• But Most of the switches do not accept Baby giant and Jumpos.

 So what? Why I am going to increase the size of a frame?

Taken this situation. When you are using VLAN (which uses 802.1Q tagging), four more extra bytes will be inserted into the frame making the frame as a giant frame (1518 +4 = 1822 bytes)
Yes, yes, How to sort out this problem?
If a port is declared as TRUNK PORT (instead of ACCESS PORT), then they will be able to handle these 1822-sized frames having the vlan tagging.

 
Is the any other method?

By configuration also we can increase the MTU size. (MTU stands for Maximum Transmission Unit).

Switch(config)#system mtu 1552
