DRAFT: BROCADE CONFIDENTIAL
LACP configuration guidelines and restrictions
This section applies to standards-based and Brocade-proprietary LAG configurations except where
specifically noted otherwise.
Follow these LACP configuration guidelines and restrictions when configuring LACP:
•All ports on the Brocade FCoE hardware can operate only in full-duplex mode.
•QoS—In the Fabric OS version 6.4.0 release, QoS commands for a LAG need to be specified on
each LAG member link, instead of on the logical LAG interface (port-group). Additionally, the
QoS commands specified on each LAG member link need to be the same on each link.
•Brocade-proprietary LAGs only—All LAG member links need to be part of the same port-group.
•Switchport interfaces—Interfaces configured as “switchport” interfaces cannot be aggregated
into a LAG. However, a LAG can be configured as a switchport.
Default LACP configuration
Table 11 lists the default LACP configuration.
LACP configuration and management
You need to enter either the copy running-config startup-config command or the write memory
command to save yo ur configur ation chang es to Flash me mory so tha t they are not lost if ther e is a
system reload or power outage.
NOTE
To see the minimum configuration required to enable FCoE on the Brocade 8000 switch, refer to
“Minimum CEE configuration to allow FCoE traffic flow” on page 29.
Enabling LACP on a CEE interface
To add additional interfaces to an existing LAG, repeat this procedure using the same LAG group
number for the new interfaces.
To enable LACP on a CEE interface, perform the following steps from Privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
2. Enter the interface command to specify the CEE interface type and slot/port number.
Example
switch(config)#interface tengigabitethernet 0/1
