When netmask is 32, loopback address is considered as Broadcast address and discovery is being aborted with the error message: "<IP address> is a broadcast address. Aborting discovery".
1. Make sure that the SNMPv3 credential is working for the IP Switch.
2. Run a quick discovery against this IP Switch: 10.xx.xxx.xx.
Discovery does not complete and CI is are not populated. The following error gets logged: "10.xx.xxx.xx is a broadcast address. Aborting discovery" and CI is not discovered.
