The following example shows the port security settings and number of secure
addresses for a specific port. The Last Intrusion MAC and Last Time Detected
Intrusion MAC fields show information about the last detected intrusion MAC
address. These fields are not applicable if no intrusion has been detected or port
security is disabled. The MAC Filter ID field is configured by the
network-access
port-mac-filter command. If this field displays Disabled, then any unknown source
MAC address can be learned as a secure MAC address. If it displays a filter identifier,
then only source MAC address entries in MAC Filter table can be learned as secure
MAC addresses.
