Issue

  • Excessive CRC and symbol receive errors on Ethernet ports can cause a range of issues from poor port performance to system instability.
  • CRC and symbol errors are typically a physical connection issue between two ports, such as SFPs/QSFPs and or cables. Other reasons can be due to incompatible switch configurations.
  • The following is an example message of a system disruption:

page fault (supervisor read data, page not present) on VA 0x2 cs:rip 0x20:0xffffffff80ac0b58 rflags 0x10246 in process NwkThd_01 on release 9.15.1 (C)
