Configure a SONET Frame Checksum

Purpose

After you have checked the FCS and determined that a problem exists, you might need to do one of the following, depending on the situation:

• Return to the Default 16-Bit Checksum
• Configure a 16-Bit Checksum
• Configure a 32-Bit Checksum
  

  NOTE: By default, SONET interfaces use a 16-bit frame checksum. You can configure a 32-bit checksum, which provides more reliable packet verification. However, some older equipment may not support 32-bit checksums.
