PyATS and ISE connection failure with renamed prompt.

AdamLowery — Thu, 17 Oct 2019 06:24:09 GMT

Hi Guys.

Im having an issue with logging into our devices that are on ISE. Im assuming the problem is with the regex not matching the login prompt, or expecting a username prompt which is not there? not sure. I have added an new regex in the my_testbed file and also tried a direct connection using unicors with the following commands:

dev = Connection(hostname='1DP-xxxxxxxxxxx-SW1',
start=['ssh 10.11.122.98'],
credentials={'default': {'username': 'axxxxxxx', 'password': 'xxxxxxxxxx'}},
os='iosxe')
dev.settings.LOGIN_PROMPT = r'TI-Pass:\s?$'
dev.settings.PASSWORD_PROMPT = r'PASSWORD:\s$'

here is my testbed file:

devices:

1DP-Txxxxxxxxxx-SW:

type: 'switch'

os: 'iosxe'

platform: CAT3K

alias: 'test'

tacacs:

username: axxxxxx

passwords:

tacacs: xxxxxxxxx

connections:

cli:

protocol: ssh

ip: "10.1xxxxxxx98"

1DP-xxxxxxxxxxx-SW1:

type: 'switch'

os: 'iosxe'

platform: CAT3K

alias: 'uut'

credentials:

default:

username: axxxxx

password: xxxxxxx

connections:

cli:

protocol: ssh

ip: "10.1xxxxx.29"

prompts:

I have tried both switches with the same error....super confused now. I dont have an issue logging into a switch not on ISE.

here is the output.

Im a bit worried about Cisco Support at the moment.
CISCO COBRA SDK only supports 2.7 which is depricated in a month and now pyATS looks like there is no community either?
