What is snCamStatAddIPHostCount?
This counter tracks the number of times the CAM (Content Addressable Memory) table has added new entries for IP host addresses. The CAM table stores MAC-to-IP address mappings used for switch forwarding decisions, and this counter shows how frequently new hosts are being discovered on the network. Network administrators monitor this value to understand host churn rates and to diagnose problems like address table exhaustion or unusual network activity patterns.
