On a configuration load, the icmp-echo property is always set disabled for a virtual address with network prefix.
ICMP and ARP behavior stops for the virtual address.
This occurs on virtual addresses that have a network prefix.
Manually reconfigure the icmp-echo property for virtual addresses with network prefixes.
The icmp-echo property is now set correctly for virtual addresses with network prefixes.
