240 BigIron RX Series Configuration Guide53-1001986-01Configuration of a LAG8c. If the original mode is passive, the converted dynamic LAG will be configured as deploypassive. Otherwise active mode is the default.d. The timeout configuration set by the command link-aggregate configure timeout will beconverted to the lacp-timeout command.e. Individual port priority set by the command link-aggregate configure port-priority will beconverted to the lacp-port-priority command.f. While the value of the link-aggregate configure key command is used in the conversion indetermining the set of ports that form an LAG, in the new LAG user interface, there is noneed for a user to explicitly configure a key. Each dynamic LAG will automatically select aunique 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 directlyconverted. This value is currently not in use by the system's LACP protocol processing, andwill 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 automaticallyconverted to the default hash-based load balancing scheme.j. Port names configured in the original interface configuration will be converted to portnames within the LAG.k. The converted LAG will be named "LAG_x", where “x” is a unique number assigned by thesystem starting from 1.Configuration of a LAGThe following configuration procedures are used to configure a LAG. Depending upon whether youare configuring a static, dynamic or keep-alive LAG, the configuration procedures may or may notapply 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 LAGcontains only one port with static and dynamic LAGs can have 2 to 8 ports.• Configuring the Primary Port for a LAG – Required for all static and dynamic LAGs. Since a keepalive LAG contains only one port, it is unnecessary to configure this parameter.• Specifying the Trunk Threshold for a Trunk Group – Optional for static and dynamic LAGs. Sincea 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. Because static LAGsdo not support LACP, it is unnecessary to configure this parameter.• Configuring an LACP Timeout – Optional for dynamic and keep alive LAGs. Because static LAGsdo not support LACP, it is unnecessary to configure this parameter.Creating a Link Aggregation Group (LAG)Before setting-up ports or configuring any other aspects of a LAG, you must create it as shown inthe following.BigIron RX(config)# lag blue staticBigIron RX(config-lag-blue)#
