Unable to log into Brocade ICX (fastiron) when RADIUS authentication for Enable is configured

I’m testing using a Brocade ICX7250. If enable authentication is disabled with the following command, everything works: aaa authentication enable default none

If enable authentication is configured to use RADIUS: aaa authentication enable default radius local

I get the following when connecting:

net_connect = netmiko.ConnectHandler(**icx)
SSH connection established to 10.0.0.2:22
Interactive SSH session established
Traceback (most recent call last):

netmiko.ssh_exception.NetMikoTimeoutException: Timed-out reading channel, data not available.

Here is what a login looks like with enable radius configured:

Using username "service_netmiko".
Using keyboard-interactive authentication.
Password:
SSH@Lab-ICX7250>en
User Name:service_netmiko
Password:
SSH@Lab-ICX7250#

from typing import from netmiko import ConnectHandler from getpass import getpass

password = getpass() secret = getpass()

brocade = { “device_type”: “cisco_ex”,
“host”: “172.16.1.1”, “username”: “admin”, “password”: password, “port”: 22, # optional, default 22 “secret”: secret, # this is the enable password “verbose”: True # optional, default False }

connection = ConnectHandler(**brocade)

connection.enable

I made up this for my Brocade MLxe and its working for me.
