LACP works by constantly exchanging custom MAC PDUs across LAN Ethernet links. The protocol
packets are only exchanged between ports that are configured to be LACP-capable.
LACP Configuration
SFTOS allows the user to enable LACP and configure LACP timeout characteristics for a particular LAG.
The following commands configure LACP:
LACP configuration example
Figure 11-133 shows the assignment of ports to a LAG. Figure 11-134 displays that the LAG is dynamic
(enabled with LACP) by default:
Figure 11-133. Example of LAG Configuration with LACP Enabled by Default
You would also need to enable the ports in the LAG.
To convert the LAG to static, use
protocol static, in Interface Port Channel Config mode.
Note: LACP is enabled by default.
Command Syntax Command Mode Purpose

Channel Config
If you converted a LAG to static, this command
reenables LACP on the LAG.
[no] port lacptimeout {short all | long
all}
Global Config Configure the system LACP timeout.
[no] port lacptimeout {short | long} Interface Config Configure the LACP timeout at a port level.
Note: The [no] port lacpmode enable command (Interface Config mode) and [no] port
lacpmode enable all command (Global Config mode) are deprecated.
