Static secure MAC addresses are typically used when the MAC addresses used are known and do not change often. The type of secure MAC address that is configured depends on the intended end result. These types of addresses are kept in an address table and in the running configuration. Sticky secure MAC addressesThis type of secure MAC address can be manually configured or dynamically learned.These types of addresses are kept only in an address table and not in the running configuration. Dynamic secure MAC addressesThis type of secure MAC address is learned dynamically from the traffic that is sent through the switchport.Static secure MAC addressesThis type of secure MAC address is statically configured on a switchport and is stored in an address table and in the running configuration.To begin with, there are three different types of secure MAC address: The switchport security feature offers the ability to configure a switchport so that traffic can be limited to only a specific configured MAC address or list of MAC addresses.
There are a couple of different ways to configure the use of switchport security and this article will review the available options and requirements. Keeping track of all of this information in a medium to large organization can be quite time consuming.
The reason may be that it requires a more granular configuration this is because a typical configuration requires the knowledge of the specific MAC address(es) that will be connecting to each switchport. One of the most overlooked security areas is the configuration of individual switchport security configuration.
