The Port Security Violations table shows information about violations that occurred on ports that are enabled for port security. The following table describes the fields in the Port Security Violations table. Table 202. Port Security Violations 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 violation MAC address. 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. 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. To configure port security settings: 1. Launch a web browser. 2. In the address field of your web browser, enter the IP address of the switch. The login window opens. Manage Switch Security 556 User Manual
