Transport CRC Checking

The Transport CRC for all data feature, allows all data to go through the Transport CRC checking function when it is enabled.

If this option is not enabled, Transport CRC checking will not be performed on packets that are non-compressible or packets less than 1024 bytes.

Compression must be enabled at the circuit level before enabling the

Transport CRC for all data feature.

This feature can be used for:

•Data protection on a WAN that has known problems, where the performance costs are tolerable

•Applications that are not tolerant of end to end CRC errors

•Network debugging purposes

Performance will be impacted when this option is enabled.
