Description: The value indicates the configured maximum size of the ARP cache used for management traffic.
What is cufwL2GlobalArpCacheSize?
This read-only Integer32, in ARP entries, reports the configured maximum size of the ARP cache used for management traffic. An admin uses it to know the capacity ceiling of the transparent firewall's ARP table for its own management-plane traffic, which affects how many management-related hosts it can track simultaneously. If this configured size seems too small relative to the number of managed devices, an admin might expect frequent ARP cache evictions.
