Configuring a LAG

d. The timeout configuration set by the command link-aggregate configure timeout will be
converted to the lacp-timeout command.
e. Individual port priority set by the command link-aggregate configure port-priority will be
converted to the lacp-port-priority command.
f. While the value of the link-aggregate configure key command is used in the conversion in
determining the set of ports that form an LAG, in the new LAG user interface, there is no
need for a user to explicitly configure a key. Each dynamic LAG will automatically select a
unique key for the system. Hence the original configured key will not be retained.
g. The command link-aggregate configure system-priority is retired and will not be directly
converted. This value is currently not in use by the system's LACP protocol processing, and
will maintain a default value of 1.
h. The lowest-numbered port will be selected as the primary port of the LAG.
i. The load balancing scheme in the command link-aggregate configure type is automatically
converted to the default hash-based load balancing scheme.
j. Port names configured in the original interface configuration will be converted to port
names within the LAG.
k. The converted LAG will be named “LAG_x”, where “x” is a unique number assigned by the
system starting from 1.
Configuring a LAG
The following configuration procedures are used to configure a LAG. Depending upon whether you
are configuring a static, dynamic or keep-alive LAG, the configuration procedures may or may not
apply as described:
• Creating a Link Aggregation Group – Required for all static, dynamic or keep alive LAGs.
• Adding Ports to a LAG – Required for all static, dynamic, or keep alive LAGs. A keep alive LAG
contains only one port while static and dynamic LAGs can have 2 to 32 ports.
• Configuring the Primary Port for a LAG – Required for all static and dynamic LAGs. Since a keep
alive LAG contains only one port, it is unnecessary to configure this parameter.
• Configuring the Load Sharing Type – Optional for all static and dynamic LAGs. Since a keep
alive LAG contains only one port, it is unnecessary to configure this parameter.
• Specifying the LAG Threshold for a LAG Group – Optional for static and dynamic LAGs. Since a
keep alive LAG contains only one port, it is unnecessary to configure this parameter.
• Configuring LACP Port Priority – Optional for dynamic and keep alive LAGs.
• Configuring an LACP Timeout – Optional for dynamic and keep alive LAGs.
• Configuring LACP BPDU Forwarding – Optional for static LAGS only. Because LACP BDUs are
discarded (dropped) on ports in which a static LAG has been configured as the default setting
as of R05.0.00
Creating a Link Aggregation Group (LAG) using
the LAG ID option
Before setting-up ports or configuring any other aspects of a LAG, you must create it first.
