SUMMARY

Trying to add by SNMP an unreachable switch fails with error 405.

STEPS TO REPRODUCE

• provide hostname and community to /switch/create-by-snmp
• click create on /switch/store-by-snmp

EXPECTED RESULTS

One of these steps should at least provide some kind of user-friendly error instead of an HTTP error page.

ACTUAL RESULTS

I get a plain white page with:

The server returned a "405 Method Not Allowed".

IMPORTANCE

Major: I am unable to add the new switches.

[rfc1036]

After switching to PHP 8.0 I have been able to add new switches, but I am still getting these errors in the log.

If anybody else incautiously upgraded to Ubuntu 24.04 then they can easily add back PHP 8.0 with something like:

/etc/apt/sources.list.d/ondrej.list:

deb http://ppa.launchpad.net/ondrej/php/ubuntu noble main

/etc/apt/preferences.d/pin-php:

# do not install by default from the PPA
Package: *
Pin: release o=LP-PPA-ondrej-php
Pin-Priority: 100

# but allow installing this php-common if needed
Package: php-common
Pin: release o=LP-PPA-ondrej-php
Pin-Priority: 990

apt update
apt install $(dpkg -l | awk '/ php8\.3-/ {print $2}' | sed -re 's/^php8\.3-/php8.0-/') php8.0-mcrypt

a2disconf php8.3-fpm
a2enconf php8.0-fpm
systemctl reload apache2.service

IXP Manager v6.x isn't supported on ubuntu 24.04.

IXP Manager v7.x is currently in development, and will use ubuntu 24.04 as the baseline platform, so it would be better to wait until 7.x is released before upgrading to ubuntu 24.04.

The bug in this issue is that there should be more graceful exception handling for switch discovery using snmp. We'll get this fixed.

I’m using Ubuntu 22, and the same issue exists in Ubuntu 20

Hi @JoyVolta - this usually happens when some data is missing. Ensure all fields are filled and particularly location/facility and cabinet/rack.

Thank you. It's resolved.
