This counter is accumulated since the last reboot of the firewall.
What is cufwL2GlobalNumArpRequests?
This Counter64, in ARP Requests, counts ARP requests issued by the transparent firewall to resolve a destination IP address, accumulated since the last reboot. An admin uses it as a baseline of normal ARP resolution activity for a bridging firewall, which helps put related counters like bad or spoofed ARP responses into context. A count that grows roughly in line with new hosts appearing on the network would be expected normal behavior.
