Can mac addresses be dynamic? MAC address entries are classified into dynamic, static, and blackhole entries. In addition, there are MAC address entries that are related to service types, for example, secure MAC and MUX MAC. They are maintained by service modules and are converted from dynamic MAC address entries.
Are MAC addresses static or dynamic? MAC addresses are usually assigned when the device is manufactured and, unlike IP addresses, they generally do not change when moving from one network to another. In other words, MAC addresses have historically been static and unique to each device.
Why is a MAC address dynamic? Dynamic addresses are addresses learned by the switch automatically, and the switch regularly ages out those that are not in use. That is, the switch removes the MAC address entries related to a network device if no packet is received from the device within the aging time.
Why are some MAC addresses static and other dynamic? Static MAC addresses in the MAC address table were manually configured. The dynamic entries in the MAC address table will time out after a while. The table is dynamic and when a frame with a source MAC address comes into a switch the table is updated to reflect that the device with that MAC address is out that port.
