Num Addr Stored

Displays he number of addresses that are currently in the Port Address Table for this port. If this object has the same value as Num Addr, no more addresses can be authorized on this port. This value must be less than or equal to Num Addr.

Max Addr

Displays the maximum value that Num Addr can be set to. It is dependent on the system resources available, and so may change as system processes change. If resources are shared between ports, this value could increase or decrease as resources are shifted around.
