3.3 MAC Address Management
3.3.1 Overview
A MAC address table records mappings of MAC addresses and interfaces to virtual local area networks (VLANs).
A device queries the MAC address table based on the destination MAC address in a received packet. If the
device finds an entry that is consistent with the destination MAC Address in the packet, the device forwards the
packet through the interface corresponding to the entry in unicast mode. If the device does not find such an
entry, it forwards the packet through all interfaces other than the receiving interface in broadcast mode.
MAC address entries are classified into the following types:
⚫ Static MAC address entries: Manually configured by the user. Packets whose destination MAC address
matches the one in such an entry are forwarded through the correct interface. This type of entries does not
age.
⚫ Dynamic MAC address entries: Automatically generated by devices. Packets whose destination MAC
address matches the one in such an entry are forwarded through the correct interface. This type of entries
ages.
⚫ Filtering MAC address entries: Manually configured by the user. Packets whose source or destination MAC
address matches the one in such an entry are discarded. This type of entries does not age.
Note
This section describes the management of static, dynamic, and filtering MAC address entries, without involving
multicast MAC address entries.
3.3.2 Displaying the MAC Address Table
Choose Local Device > Monitor > Clients > MAC List.
Displays the MAC address information of the device, including the static MAC address manually set by the user,
the filtering MAC address, and the dynamic MAC address automatically learned by the device.
