VLAN configuration guidelines and restrictions 6

DRAFT: BROCADE CONFIDENTIAL

Additionally, there are important facts you should know about the VLAN FDB:

•The VLAN FDB contains information that helps determine the forwarding of an arriving frame

based on MAC address and VLAN ID data. The FDB contains both statically configured data

and dynamic data that is learned by the switch.

•The dynamic updating of FDB entries using learning is supported (if the port state permits).

•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 100000 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 does not overwrite a new or pre-existing dynamic entry.

•Static entries do not disable the learning of dynamic entries.

NOTE

For more information on frame handling for Brocade FCoE hardware, see “Layer 2 Ethernet

overview” on page 3.

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.
