Description: The number of ICMP traceroute requests issued by the transparent firewall to resolve a destination IP address.
This counter is accumulated since the last reboot of the firewall.
What is cufwL2GlobalNumIcmpRequests?
This Counter64, in ICMP Traceroute Requests, counts ICMP traceroute requests issued by the transparent firewall to help resolve a destination IP address, accumulated since the last reboot. An admin uses it to understand how often the transparent firewall falls back on ICMP-based resolution techniques rather than ARP alone. A rising count here alongside difficulty reaching certain destinations could suggest the firewall is having trouble resolving some hosts via ARP and is compensating.
