Description (partial)

Prime Infrastructure Ping Sweep Discovery may mark all devices as unreachable, despite being reachable via external ICMP Ping

This can occur when the Prime Infrastructure Pings are blocked by Network Firewalls, IDS/IPS or other security infrastructure due to being larger than expected

The pings generated are 68 bytes, rather than the standard 56 bytes
