Hi Hank,

I am trying to connect to an ASR920 running IOS XE but don't see the platform listed in the pyats testbed documentation. So I left the platform key blank in the yaml file. I get the following error:

I tried the following in my testbed.yaml file:

devices:
asr-920-24:
type: 'router'
os: 'iosxe'
alias: 'test'
credentials:
default:
username: [redacted]
password: [redacted]
connections:
cli:
protocol: telnet
ip: "[redacted]"

I get the following error:

Traceback (most recent call last):
File "mac_lookup.py", line 295, in
layer3_devices = find_layer3_devices(testbed, args.layer3_devices)
File "mac_lookup.py", line 62, in find_layer3_devices
for name in layer3_devices_list:
TypeError: 'NoneType' object is not iterable
