ExtremeSwitching series switches support fragmentation of IP packets. The above support is included whether or not the switches are present in a SummitStack.
ExtremeXOS supports the fragmenting of IP packets. If an IP packet originates in a local network that allows large packets and those packets traverse a network that limits packets to a smaller size, the packets are fragmented instead of discarded.
This feature is designed to be used in conjunction with jumbo frames. Frames that are fragmented are not processed at wire-speed within the switch fabric.
NoteJumbo frame-to-jumbo frame fragmentation is not supported. Only jumbo frame-to-normal frame fragmentation is supported.
NoteTo set the MTU size greater than 1500, all ports in the VLAN must have jumbo frames enabled.
