Toaccomplish this, the old trunk and link-aggregation commands are maintained during startupconfiguration parsing, but disabled during normal configurations.The following process is followed during the conversion of the trunk and link-aggregation to the newLAG commands.1. For any static trunk configured using the trunk ethernet to command,the following conversion procedure is followed.a. A static LAG is created containing the port list specified in the trunk command. This LAG isthen automatically deployed.b. The lowest-numbered port from the original trunk list is selected as the primary port of theLAG.c. Any trunk config-trunk-ind command, such as port name, is converted to thecorresponding LAG commands.d. The default load balancing scheme previously known as server is converted to the defaulthash-based load balancing scheme.e. The converted LAG is named "LAG_x", where “x” is a unique number assigned by thesystem starting from 1.2. For any dynamic link aggregation (LACP) group configured using the port-level link-aggregatecommands, the following conversion procedure is followed.a. A dynamic LAG is created by grouping all ports in the original configuration having thesame link-aggregation key.b. If link-aggregate active/passive is configured originally, the converted dynamic LAG will beconfigured as deployed. Otherwise it will not be converted because such ports wereoriginally not operating under LACP.
