Why are there input errors found when viewing interface statistics on the ProxySG?



There are many reasons the ProxySG interfaces may detect input errors. Some of these causes may be related to bad cables, defective interface on switch/router/sg, duplex mismatch, etc.
To determine the root cause, it is important to try various simple troubleshooting actions such as the following:

  • Swapping cables
  • Swapping ports on switch/router/SG/Firewall and/or other
  • Hard coding duplex and speed settings on both the SG and interconnected devices
  • Swapping devices (e.g. changing the switch out with another)
  • Restarting SG and/or interconnected devices

These basic troubleshooting steps may save time by helping you find the solution prior to opening a Blue Coat technical support service request.
