Query in output of sh interface

Hi all,

I have a query in output of sh interface on ASA.

On ASA's when we do 'show interface' for a gig interface, we can get any among two,

input queue (blocks free curr/low): hardware (255/230)

output queue (blocks free curr/low): hardware (255/0)

OR

input queue (curr/max packets): hardware (0/7)

output queue (curr/max packets): hardware (0/13)

cur/low I suppose when we have underruns and overruns going on.

What i want to know is the meaning of the output. In case of curr/max its very clear.

input queue (curr/max packets): hardware (0/7)

output queue (curr/max packets): hardware (0/13)

Above means (correct me if I am incorrect), there are Zero packets currently in input queue, and 7 were the max packets seen at one time. For output queue, zero are the current packets in ouput queue and 13 were max that were seen in output queue. This is documented.

But I could not find an explaination for,

input queue (blocks free curr/low): hardware (255/230)

output queue (blocks free curr/low): hardware (255/0)

How should I interpret it? I need supporting documentaion please.

I have gone through this link :

http://www.cisco.com/en/US/docs/security/asa/asa84/command/reference/s3.html#wp1497263

But i couldn't find an explanation for blocks free current/low

Please explain me the following output:

2506116 packets input, 2624544574 bytes, 0 no buffer

       Received 0  broadcasts, 0 runts, 0 giants

       8036 input errors, 0 CRC, 0 frame, 8036  overrun, 0 ignored, 0 abort

       0 L2 decode drops

       5065834  packets output, 6024814558 bytes, 0 underruns

       0 pause output, 0 resume  output

       0 output errors, 0 collisions, 0 interface resets

       0  late collisions, 0 deferred

       0 input reset drops, 0 output reset drops,  0 tx hangs

       input queue (blocks free curr/low): hardware  (255/230)

       output queue (blocks free curr/low): hardware (254/0)

input errors????

i am mainly concerned about

  input queue (blocks free curr/low): hardware  (255/230)

       output queue (blocks free curr/low): hardware (254/0)
