Overview
In new device installations, it is possible to see that even though the device is passing traffic when it is powered off, i.e., in bypass mode, when powering it on, traffic stops passing through it.
Root Cause
In some new devices, the bridges are not enabled by default. This means that the two ports belonging to a bridge pair act independently of each other and no traffic is passed from one to the other.
Resolution
To address this issue using the WebUI:
- Navigate to Configuration > System > Network > IP Address.
- Select the bridges to enable and apply.
To address this issue using the CLI (command-line interface), execute the following commands:
en
conf t
bridge br[number] enable
Where [number] is the bridge number to enable.
