Older Arista EOS devices fail on set terminal width

Hi @ktbyers - you are bombarded with questions and give your all to the community. If you can set me and my team straight I’ll donate an hour of my wages for your time if you can point me to your donation collections tin car 😉

Here is our test code

from netmiko import ConnectHandler
import logging

logging.basicConfig(filename='/home/gears/test.log', level=logging.DEBUG)
logger = logging.getLogger("netmiko")

device = {
    'host': 'zeushammer.net',
    'username': 'zeus',
    'password': 'hammer',
    'device_type': 'arista_eos_ssh',
    'allow_auto_change': True
}

net_connect = ConnectHandler(**device)
net_connect.disconnect()

My team sees two types of responses intermittently. Sometimes from the same host where the code had previously just worked.

Here is a gist of the log output where it failed Log output where it worked

Can you help us understand the logs, why one failed vs succeeded and what we can test to improve things?

Of course yes! I do want to donate.

The output is what expect is looking for.

Exactly as sent.

We see it manually, but it’s not seen via netmiko.

I’ll confirm with the team tomorrow to grab the exact copy/paste verbatim.

@zeushammer https://github.com/zeushammer Can you just include the CLI output of a failing device for the following:

terminal width 511

In other words, when you manually execute the following from the CLI what does the Arista device show/echo to the screen.

Probably easy way for a donation is just PayPal. If you want to do this, just let me know.

Kirk

Paypal is [e-mail] (if you donate let me know, so we check/monitor it on our side).
