When you finish with the window, click OK.

Changing and Clearing the Dynamic Address Table

To change the aging time for addresses:

  1. Click the Dynamic Address tab of the MAC Addresses window.
  2. In the Aging Time field, enter a number from 10 to 1000000 (seconds; about 11.5 days).
    The aging interval applies to all switch VLANs. The default is 300 seconds.
    Note: Setting too short an aging time can cause addresses to be prematurely removed from the table. Then when the switch receives a packet for an unknown destination, it floods the packet to all ports in the same VLAN as the receiving port. This unnecessary flooding can impact performance. Setting too long an aging time can cause the address table to be filled with unused addresses; it can cause delays when a workstation is moved to a new port.
  3. Click OK to put your changes in effect and to close the MAC Addresses window.

To clear the table, click Clear All.

Adding, Modifying, Removing, and Clearing Static Addresses

To add a static address:

  1. Click the Static Address tab.
  2. Click Create to display the Create Static Address window.
  3. Complete the window.
    Note: By default, an EtherChannel (EC) port group forwards packets based on its source address. For the default source-based port groups, configure the static address to forward to all ports in the port group to avoid losing packets. For destination-based port groups, configure the address to forward to only one port in the group to avoid transmitting duplicate packets.

To modify a static address:

  1. Click the Static Address tab.
  2. Select a static address from the table.
