Handling Time out exceptions

[shaanthomas]

I am experiencing time out issues with nornir-scrapli while using jinja templates. I have a script that loads in variables from a yaml file, renders a template using jinja2, and send the config to a device using nornir-scrapli. The first two tasks are working well, however the last task is not. I am receiving the Scrapli Timeoute error. After much reasearch, I think I need to do the following: leave the timeout_socket alone, set timeout_transport to 0, then just set timeout_ops to however long it takes for your longest output to print out on the terminal. The problem is that I do not know how to set these options in nornir. Is it done in the extras field on the hosts.yaml file?
I have attached screenshots of the hosts.yaml file, script, and the terminal. Also, I have attached the Nornir log file.

nornir.log

Thank you in advance for your help.

Seems reasonable, and yes, in extras. Like here: https://github.com/scrapli/nornir_scrapli/blob/main/examples/basic_netconf_usage/nornir_data/groups.yaml#L7-L9

you can pass whatever valid scrapli args in extras.

Carl,
Thank you for your help. I will add the changes to the group file once it works with the group file. Do you recommend changing the hosts file to something that looks like this.

Carl,
Sorry to bug you again. I am still having issues. I added the timeout_transport:0 and timeout_ops: 60 variables under the data/extra key in the host.yaml file. I kept getting a noneType error.:
File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/nornir/plugins/inventory/simple.py", line 26, in _get_connection_options
hostname=c.get("hostname"),
Next. I looked at the link you sent and noticed that all the info was on the group.yaml file. I ammended my groups.yaml file. I am still getting the time out error.I have tried using multiple steps of 10. I am only changing the time_out ops variable. I have scoured the documentation. Am I missing a plugin? I thought this had something to do with the fact that I am using jinja templates with logic in the template (for loops). I took the for loop out of the template and received the same Send config error. Do you have anymore suggestions. Thanks for your quick response. I have included the hosts, group, te
nornir.log

mplate, and log file.
I really appreciate your help.

Scrapli and Nornir attached. It seems to be connecting to the switch.. which is an CSR1, but it is only reading \n which is next lines.....?

scrapli.log

nornir.log

looks like whatever you are sending in configs is not what you think it is.

Carl,
Sorry, I had to put out another fire. But I checked out the configs. Configs is a list..which is what i think should be. But there is something strange at the beginning of the list. I think it is some kind of encoding done by the jinja2 template. The '\ufeff\ufeff' thing. Have you ever come across this?

['\ufeff\ufeff', 'interface loopback100', ' ip address 100.1.1.1 255.255.255.0', '', 'interface loopback11', ' ip address 11.1.1.0 255.255.255.0', '', 'interface GigabitEthernet2', ' ip address 1.1.1.1 255.255.255.0', ' ip ospf network point-to-point', ' no shutdown', ' negotiation auto', ' no mop enabled', ' no mop sysid', '', 'ip forward-protocol nd', 'ip tcp synwait-time 10', 'no ip http server', 'ip http authentication local', 'ip http secure-server', '', 'service tcp-keepalives-in', 'service tcp-keepalives-out', 'service timestamps debug datetime msec', 'service timestamps log datetime msec', 'service password-encryption', 'service compress-config', 'platform qfp utilization monitor load 80', 'platform punt-keepalive disable-kernel-core', 'no ip gratuitous-arps', 'no ip domain lookup', '', 'end']

Carl,
I was able to fix it. The device was received the \ufeff\ufeff', before the config. I think its called a BOM. The device was not able to read it. This is encoding that is append by the Jinja 2 template depending on where you create the template. My template was created in vS Code and you can change the encode settings on VS Code . I ended up just replacing the 'ufeff\ with nothing. I used the replace method. Thanks for your help
