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.

TABLE 11	Default LACP configuration
Parameter		Default setting
System priority		32768
Port priority		32768
Timeout		Long (standard LAG) and short (Brocade LAG)

LACP configuration and management

You need to enter either the copy running-configstartup-configcommand or the write memory command to save your configuration changes to Flash memory so that they are not lost if there 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
