stp_pb2

ostinato.protocols.stp_pb2 module¶

Setup STP in Ostinato for network testing. Access and adjust STP attributes via the provided API to manage network loop prevention

To add and configure Stp in a stream, add a protocol to the stream, set the protocol id to ost_pb.Protocol.kStpFieldNumber and access the Stp object from the Protocol object's Extensions dictionary using the key stp_pb2.stp

from ostinato.protocols import stp_pb2
...
# stream is an object of type ost_pb.Stream
proto = stream.protocol.add()
proto.protocol_id.id = ost_pb.Protocol.kStpFieldNumber
my_stp = proto.Extensions[stp_pb2.stp]

You can then set Stp attributes using my_stp.<attribute>
