config.axon.port ignored when port parameter is used or defaults to 8091

[mltrev23]

Describe the bug

Hey team,

I noticed that this line in the axon.py file:

bittensor/bittensor/core/axon.py

Line 336 in ae02978

config.axon.port = port or DEFAULTS.axon.port

...ends up replacing config.axon.port with the port parameter (if provided) or defaults to 8091. This makes the config.axon.port setting kind of pointless since it only gets used if no port is passed explicitly.

What’s the recommended way to set a custom port? Should we always pass it as a parameter?

Thanks!

To Reproduce

1. python neurons/miner.py --axon.port 8092
2. However, you could see the terminal log like following:
   Axon created: Axon([::], 8091, ..., stopped, ['Synapse'])
3. If I fix the code to hand in port as a param, axon is created on 8092.

Expected behavior

We can't run multiple neurons on the same device.
