ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual Port Security Interface Configuration A MAC address can be defined as allowable by one of two methods: dynamically or statically. Both methods are used concurrently when a port is locked. Dynamic locking implements a first arrival mechanism for Port Security. You specify how many addresses can be learned on the locked port. If the limit has not been reached, then a packet with an unknown source MAC address is learned and forwarded normally. When the limit is reached, no more addresses are learned on the port. Any packets with source MAC addresses that were not already learned are discarded. You can effectively disable dynamic locking by setting the number of allowable dynamic entries to zero. Static locking allows you to specify a list of MAC addresses that are allowed on a port. The behavior of packets is the same as for dynamic locking: only packets with an allowable source MAC address can be forwarded.
