The subnumberargument ranges from 1 to 4094.DescriptionUse the interface command to enter interface/subinterface view. With the interface-number.subnumberargument specified, if the subinterface identified by the argument does not exist, this command createsthe subinterface first, and then enters subinterface view.Examples# Enter GigabitEthernet 4/0/1 interface view (assuming that the interface is a Layer 3 Ethernetinterface). system-view[Sysname] interface gigabitethernet 4/0/1[Sysname-GigabitEthernet4/0/1]# Create Ethernet subinterface GigabitEthernet 4/0/1.1 and enter GigabitEthernet 4/0/1.1 subinterfaceview (assuming that GigabitEthernet 4/0/1 is a Layer 3 Ethernet interface and the subinterface does notexist). system-view[Sysname] interface gigabitethernet 4/0/1.1[Sysname-GigabitEthernet4/0/1.1]link-delaySyntaxlink-delay delay-timeundo link-delayViewEthernet interface viewDefault Level2: System level
