Port Security Violations information Field Port Last Violation MAC VLAN ID Description The physical interface. The source MAC address of the last packet that was discarded at a locked port. The VLAN ID corresponding to the last MAC address violation. Configure a Port Security Interface 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 was not 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.
