Usage Guidelines
Usage Scenario
The MAC address table of the wireless access controller stores MAC addresses of other devices. When forwarding an Ethernet frame, the wireless access controller searches the MAC address table for the outbound interface according to the destination MAC address and VLAN ID in the Ethernet frame.
After port security is enabled on an interface by using the port-security enable command, MAC address entries learned by the interface are stored in the MAC address table as secure dynamic MAC address entries. The learned secure dynamic MAC address entries are deleted after the wireless access controller restarts. If the sticky MAC function is also enabled on the interface by using the port-security mac-address sticky command, secure dynamic MAC address entries change to sticky MAC address entries. Sticky MAC address entries are not deleted after the wireless access controller restarts.
To check the sticky MAC configuration or the learned sticky MAC address entries, run the display mac-address sticky command.
Follow-up Procedure
If the displayed sticky MAC address entries are invalid, run the undo mac-address command to delete sticky MAC address entries.
Precautions
If you run the display mac-address sticky command without parameters, all sticky MAC address entries are displayed.
If the MAC address table does not contain any sticky MAC address, no information is displayed.
- The displayed information is repeatedly refreshed, so you cannot find the required information.
- The system traverses and retrieves information for a long time, and does not respond to any request.
