%SYS-3-SYS_LCPERR3:Module [dec]: Coil [dec] Port [dec] stuck [dec] times([dec] due to lcol; [dec] due to notx)
This message indicates that the module has detected a problem with the port ASIC. The module has detected that a port is locked up. Module [dec] is the module reporting the error. Coil [dec] is the ASIC number reporting the error. Port [dec] is the ASIC port with the error. stuck [dec] is the error duration. The last two [dec] are the late collision and no data transmission counts. [dec] values start at 0.
Recommended Action: Check the port status for duplex mismatch, out-of-sync network interface cards on the workstations attached, error disable condition, late collisions, or any link level errors. If the message reoccurs, contact your technical support representative.
