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 learn-
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
