[c-nsp] WS-X6348-RJ-45 giant frames on shut ports

[Tassos Chatzithomaoglou]

I have a lot of ports in a WS-X6348-RJ-45 module (6509 - 7.3(1)), which get continuesly "MTU-Exced" frames, although they are shut 
down.

6509> (enable) sh mac 3/7
...
MAC      Dely-Exced MTU-Exced  In-Discard Out-Discard
-------- ---------- ---------- ---------- -----------
  3/7              0     265331          0           0


sw-core-ath-02> (enable) sh mac 3/12
....
MAC      Dely-Exced MTU-Exced  In-Discard Out-Discard
-------- ---------- ---------- ---------- -----------
  3/12             0     838940          0           0


But wheni move to the next 12 ports, these frames stop appearing/increasing.

sw-core-ath-02> (enable) sh mac 3/13
...
MAC      Dely-Exced MTU-Exced  In-Discard Out-Discard
-------- ---------- ---------- ---------- -----------
  3/15             0          0          0           0

Since i have enabled jumbo frames in ports 3/3-4 (which belong to the 1st group of ports), should i guess that the first 12 ports 
"receive" all the frames because of the same group they belong or is it just a CatOS bug?
