In bridge mode, the 2.5G port cannot be dialed by Fiberhome HG5582A optical cat, but it can be dialed normally when connected to the router with a gigabit port

Q: What is the reason why the 2.5G port cannot be dialed in the bridge mode of the Fiberhome HG5582A optical cat? But connecting to the router with a gigabit port can dial normally.

A: Let's analyze the problem from 3 points first:

rate negotiation is likely to fail
"2.5G can not be dialed when connected to 2.5G", but " Gigabit port can be connected to 2.5G port can be ", which may be a problem with the rate negotiation between 2.5G ports It could be that the optical cat or router failed to properly establish a link layer connection at the 2.5G rate, causing the PPPoE dialing phase to fail, resulting in the failure to dial.
the 2.5G port of the Optical Cat is not correctly configured as a bridge WAN port
Some users have reported that some of the 2.5G ports of the Optical Cat are not bridged WAN ports by default, and you may need to manually set this port to "WAN port in bridge mode" in the background of the optical cat, otherwise PPPoE packets cannot be transmitted even if the physical connection is normal.

router's 2.5G port is not correctly set to WAN port
there are also cases where users do not switch the router's 2.5G port to WAN mode, causing it to still work as a LAN port and naturally unable to dial.

Troubleshooting steps:

1. Check the configuration of the Optical Cat 2.5G port: Log in to the Optical Cat background and check whether the 2.5G port has joined the bridge WAN connection.

2. Check the router's 2.5G port configuration: Log in to the router's background and make sure that its 2.5G port is set to a WAN port instead of a LAN port.

3. Forced rate negotiation test: If the device supports it, try to force the router's 2.5G port to 1Gbps mode and see if the dialing can be successful to confirm whether it is a rate negotiation problem.

4. Replace network cable test: Use high-quality network cables of Category 5 or more to rule out the possibility of 2.5G negotiation failure due to cable quality.

5. MAC address cloning (optional): If the carrier binds a MAC, you can try cloning the optical cat MAC to the router's WAN port and try again
