Switching off V1 module in a mix of V1 and V2 modules on Provision OS
When the application detects a device that is capable of starting Service Insertion but has V1
modules, a Service Insertion tunnel fails to establish and the application will fallback to using
OpenFlow.
To enable Service Insertion, turn off V1 module. You can turn off V1 module from the CLI or through
SNMPv3.
• From the CLI, enter the command no allow-v1-modules.
The V1 modules are disabled and are not operational.
OR
1. From SNMPv3, set hpSwitchAllowV1Modules to false.
2. To confirm the status, enter the following command from the switch terminal: getMib
hpSwitchAllowV1Modules.0
The output must be 2.
