    Excessive Transmit Discards between 3560 interface and LWAPP1141

    tydirium

      I am new to these forums so I am not sure if this is the correct place to post these questions so please forgive me.

       

      We are seeing Transmit Discards in excess of 100,000 on one of our Cat3560 (12.2(44)SE5 and a Cisco LAP1141.  When drilling down into the two two interface, we are not seeing where these discards are coming from and none of the numbers are matching up.  

       

      NPM is reporting:

      NODEINTERFACERECEIVE
      ERRORS
      RECEIVE
      DISCARDS
      TRANSMIT
      ERRORS

      104,016 discards 

       

      While the access point shows:

       5 minute output rate 3000 bits/sec, 4 packets/sec

           93252704 packets input, 149305006 bytes, 0 no buffer

           0 lost carrier, 0 no carrier, 0 pause output

           0 output buffer failures, 0 output buffers swapped out

      And finally the switchport is reporting:

           146171 packets input, 19641802 bytes, 0 no buffer

           0 output errors, 0 collisions, 0 interface resets

           0 lost carrier, 0 no carrier, 0 PAUSE output

           0 output buffer failures, 0 output buffers swapped out

       

      Does anyone have any ideas what may be causing these transmit discards to report?  Thanks.
