You need jumbo frames when running the Extreme Networks VMAN implementation. With SummitStack or ExtremeSwitching series switches, you can enable and disable jumbo frames on individual ports before configuring VMANs. For more information on configuring VMANs, refer to VLANs.
Jumbo frame support is available on ExtremeSwitching series switches that are operating in a SummitStack. For information about displaying jumbo frame status, see Displaying Port Information.
