While I try to search for an IP address, it will show 3 devices with different ip's & host name.
Dx NetOps Spectrum any version
Functioning as designed
If you have 3 devices and they each have a common IP address in the ipAdEntAddrtable (attribute), and you do a locator search for that IP address, you will find all 3 devices. If a trap is sent from the common IP address it will be applied to all 3 devices that share that address. If you wish to change this, it would need to be changed at the device level
