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.

VLAN configuration guidelines and restrictions

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.
VLAN configuration and management
NOTE
To see the minimum configuration required to enable FCoE on Brocade FCoE hardware, refer to
“Minimum CEE configuration to allow FCoE traffic flow”
on page 35.
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.
