LACP configuration guidelines and restrictions
This section applies to standards-based and Dell-proprietary LAG configurations except where
specifically noted otherwise.
Follow these LACP configuration guidelines and restrictions when configuring LACP:
• All ports on the Dell FCoE hardware can operate only in full-duplex mode.
• QoS—In the Fabric OS version 6.3.1_cee 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.
• Dell-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 12 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 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 Dell M8428-k switch, refer to
Chapter 3, “Initial FCoE and CEE Configuration”.
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.
