7-7 Book Title OL-xxxxx-xx Chapter 7 Configuring the Ethernet Switches How to Configure Ethernet Switches Configuring MAC Table Manipulation For information on how to configure MAC table manipulation, see the following URL: http://www.cisco.com/en/US/docs/ios/12_3t/12_3t8/feature/guide/esw_cfg.html#wp1048223 The URL contains information on the following topics: Enabling known MAC address traffic Creating a static entry in the MAC address table Configuring the aging timer Verifying the aging time Port Security The topic of enabling known MAC address traffic deals with port security. Port security can be either static or dynamic. Static port security allows the user to specify which devices are allowed access through a given switch port. The specification is done manually by placing allowed device MAC addresses in the MAC address table. Static port security is also known as MAC address filtering. Dynamic port security is similar. However, instead of specifying the MAC address of the devices, the user specifies the maximum number of devices that will be allowed on the port. If the maximum number specified is more than the number of MAC addresses specified manually, the switch will learn the MAC address automatically, up to the maximum specified. If the maximum number specified is less than the number of MAC addresess already specified statically, an error message will be produced. The following command is used to specify static or dynamic port security.
