Configuring Dynamic MAC Address Parameters
The Dynamic Addresses Setting Page enables entering the aging interval for the
MAC address table.
To enter the aging interval for dynamic addresses:
STEP 1 Click MAC Address Tables > Dynamic Address Settings. The Dynamic Addresses
Setting Page
opens.
STEP 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.
STEP 3 Click Apply. The Dynamic MAC Address Table is updated.
Querying Dynamic Addresses
The Dynamic Addresses Page enables querying the Dynamic MAC Address table
according to the following criteria:
• Interface type
• MAC addresses
• VLAN
This page displays the dynamically-learned MAC addresses. You can clear the
dynamic addresses from the MAC address table and specify a query criteria to
display a subset of the table, such as the MAC addresses learned on a specific
interface. You can also specify how the query results are sorted. If no filter criteria
are entered, the entire table is displayed.
To perform query dynamic addresses:
STEP 1 Click MAC Address Tables > Dynamic Addresses. The Dynamic Addresses Page
opens.
STEP 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.
