occur when the number of CRC errors in Fibre Channel frames for specific source ID (S_ID) and
destination ID (D_ID) pairs change. These messages might also be caused by dirty equipment,
temperature fluctuations, and aging equipment.

area of the End-to-End Performance Monitor class helps you tune your fabric. To reduce CRC
messages, experiment with alternative topologies and cabling schemes.
