SUMMARY

Parser does not work when the data is passed to it.

textfsm.parser.TextFSMError: State Error raised. Rule Line: 12. Input Line: show interfaces description

show_int_desc_parsed = parse_output(platform="cisco_ios", command="show interfaces description", data=show_int_desc)

STEPS TO REPRODUCE

Connect to cisco device using Netmiko and run the command "show interfaces description" and pass the output into parse_output

EXPECTED RESULTS

Using textfsm=True should return a JSON data structure

ACTUAL RESULTS

raise TextFSMError('State Error raised. Rule Line: %s. Input Line: %s'
textfsm.parser.TextFSMError: State Error raised. Rule Line: 12. Input Line: show interfaces description

@itdependsnetworks @jmcgill298 can you please help

[FragmentedPacket]

It appears the command is in the output you're providing the parse_output command. What does your merino code look like for this call?

[sakabio]

from netmiko import Netmiko
from textfsm import TextFSM
from ntc_templates.parse import parse_output
import getpass

net_connect = Netmiko(host='x.x.x.x', username='username', password=password, device_type='cisco_ios')

show_int_desc = net_connect.send_command_timing("show interfaces description", strip_command=False, strip_prompt=False)

show_int_desc_parsed = parse_output(platform="cisco_ios", command="show interfaces description", data=show_int_desc)

print(show_int_desc_parsed)

[diepes]

@sakabio, to better debug add print(show_int_desc) before parse_output

my guess is that the command is included in show_int_desc e.g. "show interface description" and this is tripping up textfsm.

[FragmentedPacket]

You either want to strip command and strip prompt to true or remove them from the output prior via regex or string manipulation

@FragmentedPacket thanks this worked like a charm.
