 TX BIP−16 Error Description
      Clearing the Errors
 Related Information

The bit−interleaved parity with sixteen bit errors (BIP−16) is generated when the BFrame is created on the
ingress and which stays with it until the cell is extracted on the egress of the switch. The 

TX BIP−16

 error

count is taken at the BIF−TX as the BFrame is transmitted onto the backplane.

For more information on document conventions, see the Cisco Technical Tips Conventions.

There are no specific prerequisites for this document.

This document is not restricted to specific software and hardware versions.

Because the data path up to the BIF−TX is on a single card, 

TX BIP−16

 errors indicate an error on the

reporting card, which makes isolating the fault easy. The errors indicate corruption of the BFrame which
should appear as either BFrame Parity or Payload errors on the trunk or port statistics of the receiving card.

Follow the instructions provided below to clear 

TX BIP−16

 errors:

Replace the card on which the Tx BIP−16 errors occur.

A hardware problem usually results in the maximum rate count being logged, but can occur only if
traffic flows through the card. If less than the maximum rate is seen, it is possible that the
configuration of the BFrame header for one particular channel may be incorrect. However, a hardware
failure could cause this as well.
