VLAN configuration guidelines and restrictions 4 • Dynamic FDB entries are not created for multicast group addresses. • Dynamic FDB entries are aged out based on the aging time configured per Brocade FCoE hardware. The aging time is between 10 and 1000000 seconds. The default is 300 seconds. • You can add static MAC address entries specifying a VLAN ID. Static entries are not aged out. • A static FDB entry overwrites an existing dynamically learned FDB entry and disables learning of the entry going forward. NOTE For more information on frame handling for Brocade FCoE hardware, see "Layer 2 Ethernet overview" on page 8. VLAN configuration guidelines and restrictions Follow these VLAN configuration guidelines and restrictions when configuring VLANs. • In an active topology, MAC addresses can be learned, per VLAN, using Independent VLAN Learning (IVL) only. • A MAC address ACL always overrides a static MAC address entry. In this case, the MAC address is the forwarding address and the forwarding entry can be overwritten by the ACL. • The Brocade CEE switch supports Ethernet DIX frames and 802.2 LLC SNAP encapsulated frames only. Default VLAN configuration Table 6 lists the default VLAN configuration.

NOTE You need to enter either the copy running-config startup-config command or the write memory command to save your configuration changes to Flash so that they are not lost if there is a system reload or power outage.
