Modifying the Global Configuration for Remote Device Connections

Global settings for TCP connections from the Cisco Provider Connectivity Assurance Sensor Control can be modified in this screen. You can change the base TCP port numbers for NFV tunnels and for flow broker TCP connections. The base port numbers are used to derive the actual TCP port numbers when the device is connected to Sensor Control in IP agnostic mode. For the NFV tunnel from the Sensor Control to the device, the actual TCP port number is the NFV tunnel base port number plus the device's instance index. For the Sensor Control's TCP connection to the device for flow broker data collection, the TCP port number is the flow broker base port number plus the device's instance index.

The NFV and flow broker require independent base port numbers to
accommodate the range of devices. You need to ensure the port number ranges for NFV and flow broker are not overlapping by taking into consideration the actual number of devices in your network.

The NFV and flow broker base port number could be in the Users Range (1024 - 49151) defined in RFC6335, but should preferably be in the Dynamic/Private Range (49152 - 65535).

▶To modify the global configuration for remote device connections

1. Access the page System ▶ Configuration ▶ RemDev Connection.
   The Global settings for remote-device connections window opens.

2. Enter the values for NFV tunnel base TCP port number and flow broker base TCP port number, FlowBROKER base TCP port number, Override-config and Autoupdate.

3. Click Apply.

For information on specific parameters, refer to the following table.
