TEMPLATE USING

STEPS TO REPRODUCE

cmd = ["show boot"]
try:
    net_connect = ConnectHandler(**device)
    show = net_connect.send_command(cmd, use_textfsm=True)
    pprint(show)
except (ReadTimeout, NetmikoTimeoutException) as error:
    print(f"{error} Connection timed out to {device['host']}")
except NetmikoAuthenticationException as error:
    print(f"{error} Authentication failed to {device['host']}")
except (IndexError, ValueError) as error:
    print(f"{error} {device['host']} had a problem parsing the output")

EXPECTED RESULTS

Would return formatted data like every other command using textfsm??? show version/sh int status/sh clock/sh vlan brief works

ACTUAL RESULTS

State error raised

please provide the output of the command

The white space in the show boot output changed during a Cisco IOS release.

Currently:
^Boot\soptimization\s:\s${BOOT_OPTIMIZATION}

Suggested:
^Boot\s+optimization\s+:\s+${BOOT_OPTIMIZATION}

I'm working up a PR for this.

Hello @bskine
I have submitted PR #1623 to address the white space changes that appear in show boot in current IOS releases. I was able to locate a 3560cx to pull example raw output from.
