This command displays the port-security settings for the port(s). If you do not use a parameter, the command displays the Port Security Administrative mode. Use the optional parameters to display the settings on a specific interface or on all interfaces. Instead of unit/slot/port, lag lag-intf-num can be used as an alternate way to specify the LAG (Link Aggregation Group) interface. lag lag-intf-num can also be used to specify the LAG interface where lag-intf-num is the LAG port number.
