What is hm2AgentPortSecurityDynamicCount?

This read-only Unsigned32 reports how many MAC addresses are currently dynamically locked onto this port. Admins monitor it against hm2AgentPortSecurityDynamicLimit to see how close a port is to its dynamic-learning ceiling. A value of 600 on a port with the default limit of 600 means the dynamic table for that port is completely full.
