Root cause

Versions 11.0 and above no longer support the multi-port mode of bridge (i.e. 1 LAN port and 2 WAN ports or 2 LAN ports and 1 WAN port), and only support single bridge or multi-bridge mode. Therefore, you need to modify the deployment mode and then upgrade the version.

solution

You need to change the IAG from the bridge multi-port mode to the single bridge or multi-bridge mode deployment according to the current network environment. After the modification is completed, re-upgrade to version 11.0.
