    In this case, you should configure TR-TERF to not strip the 32-bit CRC and configure the MAC to add a hardware-calculated CRC. This has the effect of reducing the burden of calculating a CRC in the software. Example dagconfig noterf_strip tx_crc ©2004 - 2008 Endace Technology Ltd. Confidential - Version 13 - November 2008...

This reduces the possibility of a buffer under-run occurring if insufficient data is committed in a burst and the process is not scheduled by the OS to run in a timely manner.
  • Page 45 If guaranteed inter-packet timing is required, Endace recommends that TR-TERF be enabled on only one interface at a time. Applicable to Multi port DAG cards only. ©2004 - 2008 Endace Technology Ltd. Confidential - Version 13 - November 2008...
