  • Cisco Nexus 7000 Series Switches

Known Affected Releases

6.2(2)S9

Description (partial)

Symptom:
The FEX port is unable to report CRC error as output under the 'show interface'  statistics and consequently the ifOutErrors will show zero for CRCs.


N7K# show interface Eth140/1/20 counters detailed | grep CRC
  Output CRC Errors:                              9349243


N7K# sh int eth140/1/20 | begin TX
