In port group view, the user only needs to input theconfiguration command once on one port and that configuration will apply to all ports in the port group.This effectively reduces redundant configurations.A Port group could be manually created by users. Multiple Ethernet ports can be added to the same portgroup but one Ethernet port can only be added to one port group.Table 1-2 Configuring a Port GroupOperation Command RemarksEnter system view system-view —Create a port group or enter thespecified port group view port-group group-id RequiredAdd an Ethernet port to aspecified port group port interface-list Required
