Interface Configuration:
Many features are enabled for a particular interface. The Interface commands enable or
modify the operation of an interface. In this mode, a physical port is set up for a specific logical connection operation.
The Interface Configuration mode provides access to the router interface configuration commands.
This section has three interface configuration,
Port interface, LLAG interface,
and
VLAN interface
. For Port interface,
type
interface IFNAME
in global configuration mode. Then User can enter the interface configuration mode. In this
mode, User can configure port settings. In port interface, the name of Gigabit Ethernet port 1 is GigabitEthernet 1/1,
GigabitEthernet 1/2 and so on. Type
exit
