Platforms: All ePMP AC platforms Firmware versions: 4.7.1 and newer
Switching AP to a different channel always caused disconnection of all Subscriber Modules for ePMP platforms that led to services interruption for customers. Sometimes it could take up to 3-5 minutes to reconnect back to the AP depending on how many frequencies are configured in the scanning list on SM.
The Seamless Channel Switching feature is implemented starting 4.7.1 firmware that brings no disruption of Internet access for end users when the operator needs to change Channel Bandwidth or Primary Frequency on the AP.
The new feature is available on AC devices in TDD and TDD PTP modes only.
It is enabled by default and no actions are required from user for the configuration.
You mention it is available on AC devices - I understand if this is only available for AC and newer APs. I’d like to request, however, that it is made available for mixed SMs as @Alessio_Garavano asked. Either way, it is nice to see this feature now available.
