IR1101: application hosting and cellular interfaces

[Andre Chrcanovic]

Hi everyone!

Regarding IR1101 application hosting: are the cellular interfaces mapped to the container that runs the application (via VirtualPortGroup)?

Is it possible for a Docker type C based application to send/receive (via sockets) TCP frames to/from the cellular interfaces?

Is it possible for this same application to have access to information (like RSSI) related to the cellular interfaces? Cisco Application Framework (CAF) has support for that?

Thanks in advance,
Andre Chrcanovic

Hello Andre - 

IOx applications are connected to the VPG0 interface and they have not knowledge of how they are connected afterwards. This is a routing decision made by the IR1101 routing process. Therefore, no, the Cellular interfaces are not directly mapped to running IOx applications, but yes it is possible for a Docker container to send/receive TCP through the Cellular interface (using normal routing, or policy based routing). 

CAF does not support getting RSSI information, or any IOS-XE configuration, but you can still use SNMP like so for RSSI:

Hope this helps
