Cyclic redundancy check (CRC) or framing errors on the EX platform on any physical interface might generate the message "FCS Errors Found." This article describes the issue and explains how to clear the log of these messages.
Frame Check Sum error messages (FCS Errors Found) are seen on the EX platform at an interval of approximately 60 minutes. The message is generated for an interface where a CRC error is seen, even though the CRC error counter is not incrementing.
root@LAB# run show log messages | match error Nov 10 15:51:59 LAB pfed: send_if_error_snmp_traps 445 FCS Errors Found for Interface:ge-2/0/14SNMP Index:516 Error Count:359393 Nov 10 16:39:59 LAB pfed: send_if_error_snmp_traps 480 FCS Errors Found for Interface:ge-2/0/14SNMP Index:516 Error Count:359393 Nov 10 17:39:59 LAB pfed: send_if_error_snmp_traps 480 FCS Errors Found for Interface:ge-2/0/14SNMP Index:516 Error Count:359393
This message is informational and can be safely ignored.
Clear the interface statistics to stop logging this message.
Execute the command show interfaces ge-2/0/14 extensive | match crc :
show interfaces ge-2/0/14 extensive | match crc
root@LAB> show interfaces ge-2/0/14 extensive | match crc FIFO errors: 0, HS link CRC errors: 0, MTU errors: 0, Resource errors: 0 CRC/Align errors 359393 0 <<<<< CRC errors were pushed through IXIA for 40-50 sec.
Log is seen for the interface even though the CRC error counter is not incrementing:
root@LAB# run show log messages | match error Nov 10 15:51:59 LAB pfed: send_if_error_snmp_traps 445 FCS Errors Found for Interface:ge-2/0/14SNMP Index:516 Error Count: 359393 Nov 10 16:39:59 LAB pfed: send_if_error_snmp_traps 480 FCS Errors Found for Interface:ge-2/0/14SNMP Index:516 Error Count: 359393 Nov 10 17:39:59 LAB pfed: send_if_error_snmp_traps 480 FCS Errors Found for Interface:ge-2/0/14SNMP Index:516 Error Count:

Execute the command run clear interfaces statistics ge-2/0/14 to clear the interface.
run clear interfaces statistics ge-2/0/14
root@LAB# run clear interfaces statistics ge-2/0/14
After the interface statistics are cleared, the log message will no longer be generated.
