Hi,

Thank you for the update last week.

When I use the following function, I receive a stack trace:

device.get_mac_address_table()

Traceback (most recent call last):

Using a switch that has been factory reset and only the basics of SSH configured.
I can run all other 'Get info' commands succesfully.

Seems very related to: napalm-automation-community/napalm-ftos#2

Please do let me know if I can help troubleshoot further.

请问大佬是什么问题

Hello,

I would like to know against what models you are testing the driver. I could help you to test it with S2700, S7700, S7703, NE40E-X8, NE40E-X3.
I did not see this driver before and I developed one that fit my needs. mainly for S2700 to get info needed in netbox.
I tried this one but I could not get the info expected in netbox (get_facts mainly, like uptime, model version or serial number)
are you planning to upgrade to the newest napalm driver model and dependencies?

Facing issue: Unexpected output data: [" ^\nError: Unrecognized command found at '^' position."] I hope issue is my device have super mode password, passed secret optional value still facing same issue

def get_lldp_neighbors_detail(self):
results = {}
command = 'display lldp neighbor brief'
output = self.device.send_command(command)
lines = output.split("\n")
for line in lines:
# translate Huawai
skip_lines = ['local', '-----']
local_iface = line[:14].strip()
remote_port = line[39:65].strip().replace(" ", "")
remote_system_name = line[14:39].strip()
local_iface = local_iface.replace("XGE", "XGigabitEthernet")
remote_port = remote_port.replace("XGE", "XGigabitEthernet")

        if local_iface[:5].lower() not in skip_lines:
            if local_iface not in results:
                results[local_iface] = []

            neighbor_dict = dict()
            neighbor_dict['remote_port'] = py23_compat.text_type(remote_port)
            neighbor_dict['remote_system_name'] = py23_compat.text_type(remote_system_name)
            results[local_iface].append(neighbor_dict)
    return results

this is working for 10gig interfaces in NetBox.. i have no gig nor 40/100 gig interfaces active to test against.. is suspect that the replace statement needs to be expanded tot get them equal to the names in the config.

I wrote this as a start for use in netbox only..so see it as a partial implementation

If you need me to test on a couple of VRP devices i am glad to help out.. i am in no way a python developer :)

Hi @tkspuk

I'm writing because i'm very interested on becoming a maintainer of this repository. I have used this driver in a project and developed multiple methods to add support for other Huawei devices, routers specifically: NE40E-X2, NE40E-X16, NE8000 and ATN 910C.

I know i can simply make pull request and wait for your approval, but i want to be an active contributor adding codes and reviewing others people Pull requests and issues.

Regards

Hello !

I have 2 switches S7706,
and I'm attempting to perform a get_config() operation using napalm.

On one of the switches, the process is not completing and results is:

"_Pattern not detected: '<Switch\-S7706\-core>' in output.
Things you might try to fix this:

1. Explicitly set your pattern using the expect_string argument.
2. Increase the read_timeout to a larger value.
   You can also look at the Netmiko session_log or debug log for more information._"

I have tried every combination of optional_args (without any success):
global_delay_factor, fast_cli, timeout, conn_timeout, session_timeout.

With cli, using SSH, I don't have any problem.
I also mention that get_facts(), works as expected.

I am using:
Python 3.11.2
Netmiko 4.2.0
Napalm 4.1.0

The following script also fails:
napalm --vendor huawei_vrp --user username --password secret --optional_args 'port=22, global_delay_factor=2, read_timeout_override=30.0' 10.10.10.10 call get_config

What do you think might be causing this, and what else can I try?

In the new Napalm version py23compat is no longer available.
Crashing the vrp driver.

Hi,

In the Netbox web-interface when going to the Status window of my device, I get the following error:

Error Fetching Device Environment Data
Method get_environment failed: 'NoneType' object has no attribute 'group'

The Status window has partially filled in information.
Below "Device Facts", everything is filled except for: FQDN, Model and OS Version. These 3 fields have as value "unknown".
Below "Environment" no information is filled.

Running Netbox locally I get the following result:

python3 manage.py runserver 0.0.0.0:8000 --insecure

Running the following, I get a stack-trace:

>>> device.get_environment()
Traceback (most recent call last):

                                         ^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'group'

File /opt/netbox-3.7.4/venv/lib/python3.11/site-packages/napalm_huawei_vrp/huawei_vrp.py contains the following code:

        fan_output = self.device.send_command(fan_cmd)
        power_cmd = self.device.send_command(power_cmd)
        temp_cmd = self.device.send_command(temp_cmd)
        cpu_cmd = self.device.send_command(cpu_cmd)
        mem_cmd = self.device.send_command(mem_cmd)

fan_cmd = "display fan"
power_cmd = "display power"
temp_cmd = "display temperature all"
cpu_cmd = "display cpu-usage"
mem_cmd = "display memory-usage"

None of the display commands listed above, exist on my Huawei Cloudengine.
However, I do have the "display health" command, that displays the same information but sorted differently.

I have tried the 5 display commands on 2 Cloudengines running VRP "Version 8.180" (2018) and "Version 8.191" (2020) respectively.

In short, I think the ""def get_environment(self)" function should be modified to use the results of "display health" instead.

Thank you for your continued development.

You have a misprint in open method. At line 126 you wrote - "huawei_telent" instead of "huawei_telnet". It entails an error when you try to use telnet connection instead ssh

I wanna contribute my effort to upgrade the Huawei driver continually.
The network devices that i can connect to are in the company's inner network.
It's will be helpful that you guys provide the Huawei device, thanks.
I have been using Napalm to develop the Network Automation Project in our company since 2018.

In routers that have 2 cfcards, saving files need to save in slave cards also. So when I want to use the device.commit_config() API, because it trying to save a file into cfcard the router ask an extra question to save the file to slave cfcard:
<BRKSAB_KS0006>save config_20221004_1026.cfg
Warning: Are you sure to save the configuration to cfcard:/config_20221004_1026.cfg? [Y/N]:
By the “y” command that will be sent to the node using “_save_config(self)” function the node goes to the next step, so the situation will be like below:

Warning: cfcard:/config_20221004_1026.cfg exists,overwrite? [Y/N]:y
Now saving the current configuration to the slot 11 .
Info: Save the configuration successfully.
Warning: Are you sure to save the configuration to slave#cfcard:/config_20221004_1026.cfg? [Y/N]:

But in the last line, the node asks to save the file into slave cfcard, but the code doesn’t have an answer for this question. So that it senses an error. In continue we can see the _save_config(self) code:

def _save_config(self, filename=''):
"""Save the current running config to the given file."""
command = 'save {}'.format(filename)
save_log = self.device.send_command(command, max_loops=10, expect_string=r'Y/N')
# Search pattern will not be detected when set a new hostname, so don't use auto_find_prompt=False
save_log += self.device.send_command('y', expect_string=r'<.+>')
search_result = re.search("successfully", save_log, re.M)
if search_result is None:
msg = "Failed to save config. Command output:{}".format(save_log)
raise CommandErrorException(msg)

I have been trying to add change the function code to like below, but it doesn’t work while it seems true:

def _save_config(self, filename=''):
"""Save the current running config to the given file."""
command = 'save {}'.format(filename)
save_log = self.device.send_command(command, max_loops=10, expect_string=r'Y/N')
# Search pattern will not be detected when set a new hostname, so don't use auto_find_prompt=False
save_log += self.device.send_command('y', expect_string=r'Info:')
savecfcard = re.search(“save the configuration to slave#cfcard” , )
if savecfcard == True:
save_log += self.device.send_command('y', expect_string=r'<.+>')
search_result = re.search("successfully", save_log, re.M)
if search_result is None:
msg = "Failed to save config. Command output:{}".format(save_log)
raise CommandErrorException(msg)

Would you help me please to solve this problem?

Hi @tkspuk,
