There are many reasons the Edge SWG (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 Broadcom technical support service request.
