Discovery is not skipping Cisco IP Phones

Help
1

Hey everyone,

New to LibreNMS. I did a search for Cisco IP Phones on the forum, but couldn’t find any other threads about this. The documentation indicates that by default discovery is disabled for Cisco IP Phones via XDP. However, when running discovery.php -d, I’m seeing attempts to poll these devices as they’re discovered. Here’s a sample from one of the discovery attempts.

Any feedback or guidance will be greatly appreciated!

Thanks!
