Configuring and Monitoring Port Security
Port Security Command Options and Operation
Retention of Static MAC Addresses
Learned MAC Addresses
In the following two cases, a port in Static learn mode ( learn-mode static)
retains a learned MAC address even if you later reboot the switch or disable
port security for that port:
■ The port learns a MAC address after you configure the port with l earn-
mode static in both the startup-config file and the running-config file
(by executing
write memory).
■ The port learns a MAC address after you configure the port with learn-
mode static in only the running-config file and, after the address is
learned, you execute
write memory to configure the startup-config file
to match the running-config file.
Assigned/Authorized MAC Addresses
If you manually assign a MAC address (using mac-address < mac-addr >) and
then execute write memory, the assigned MAC address remains in memory
unless removed by one of the methods described below.
Removing Learned and Assigned Static MAC Addresses
To remove a static MAC address, do one of the following:
■ Delete the address by using no port-security < port-number > mac-
address < mac-addr >.
■ Download a configuration file that does not include the unwanted
MAC address assignment.
■ Reset the switch to its factory-default configuration.
Displaying Current Port Security Settings
The CLI uses the same command to provide two types of port security listings:
■ All ports on the switch with their Learn Mode and (alarm) Action
■ Only the specified ports with their Learn Mode, Address Limit, (alarm)
Action, and Authorized Addresses
