Hi Mansoor,
Its a bad hardware as it is failing the POST test.
You have to get it replaced.

Hi Mansoor,
AFAIK you cannot use these ports as they are failing the post test which is POWER ON SELF TEST indicating hardware failure
HTH,if yes please rate the post.

Actually, i am troublshouting a switches, so i am asking such type of question,
Next Question,
in a Show Logg command i found this error.
00:00:10: %PLATFORM_HW-3-ASIC_BIST_FAILURE:
C2950 BIST failed for memory XQ0 count 1

Hi Mansoor,
This message means that during power-on self-test (POST), the built-in memory test on the ASIC failed, which might occur because the ASIC has a defect. [chars] is the name of the ASIC memory table, and [dec] is the number of address failures in the built-in memory test.
If this is the same switch on which you are getting loopback test failure messages you get it replaced from TAC.
Also to get the details of different error messages on 3550, 2955, 2950 and 2940 Switches have a look at this link
HTH, if yes please rate all post.
