Description
The number of frames received that were larger than maximum allowed MTU
the FCS bits and excluding the frame header) and that have either an FCS error or an alignment
error.
Note For information about the maximum allowed MTU size on the switch, see the
global configuration command.
The number of frames discarded because of lack of receive buffer memory.
