Overview Use this command to enable the device to forward jumbo frames. For more
information, see the
When jumbo frame support is enabled, the maximum size of packets that the
device can forward is 9710 bytes of payload.
Use the no variant of this command to remove jumbo frame support, and restore
the default MRU size (1500 bytes) for switch ports.
NOTE
