Generally, a switching device provides multiple interfaces, many of which have the same configuration. If these interfaces are configured one by one, the operations are complex and errors may occur. To resolve this problem, create an interface group and then add the interfaces that require the same configuration command to the interface group. When you run the configuration command in the interface group view, the system automatically executes this command on all the member interfaces in the interface group, implementing batch configuration. As shown in Figure 1
, a large number of interfaces exist on the aggregation and access switches. Many of these interfaces have the same configurations. If they are configured separately, the management cost is high. Therefore, you can create interface groups on these switches.
