Re: how to trblshoot and solve it

The enc_out errors are commonly seen when ports bounce. The errors of concern are the enc_in and crc g_eof on switch 19 ports 22 and 23. If the errors continue to increment it indicates a physical layer issue on those connections. It could be sfp on either end or cable/infrastructure between the switches. Try cleaning/reseating cable connections or replacing cable or sfp on one side until errors clear up.
