Dynamic MAC Addresses

The Dynamic Address Table contains the MAC addresses acquired by monitoring the source addresses of traffic entering the switch. When the destination address for inbound traffic is found in the database, the packets intended for that address are forwarded directly to the associated port. Otherwise, the traffic is flooded to all ports in the VLAN of the frame.

To prevent the bridging table from overflowing and to make room for new addresses, an address is deleted from the bridging table if no traffic is received from a dynamic MAC address for a certain period. This period of time is the aging interval. This time is configured in the Dynamic Address Settings page.

The dynamic addresses can be queried in the Dynamic Addresses page.

Setting Dynamic MAC Address Settings

To enter the aging interval for dynamic addresses:

  1. Click MAC Address Tables > Dynamic Address Settings. The Dynamic Addresses Setting page opens.
  2. Enter Aging Time. The aging time is a value between the user-configured value and twice that value minus 1. For example, if you entered 300 seconds, the aging time is between 300 and 599 seconds.
  3. Click Apply. The Dynamic MAC Address Table is updated.

Querying Dynamic Addresses

To view all dynamic addresses or a subset:

  1. Click MAC Address Tables > Dynamic Addresses. The Dynamic Addresses page opens.
  2. In the Filter block, enter the following query criteria:
    • VLAN ID--Enter the VLAN ID for which the table is queried.
    • MAC Address--Enter the MAC address for which the table is queried.
    • Interface--Select the interface for which the table is queried. The query can search for specific ports or LAGs.
    • Dynamic Address Table Sort Key--Enter the field by which the table is sorted. The address table can be sorted by VLAN ID, MAC address, or interface.
  3. Select the preferred option for sorting the addresses table in the Dynamic Address Sort Key.
  4. Click Go. The Dynamic MAC Address Table is queried and the results are displayed.

Click Clear Table to delete all of the dynamic MAC addresses.
