Interface configuration mode is a specific mode in network device configuration, typically found in Cisco devices, where administrators can configure settings for a particular network interface, such as Ethernet or serial ports. In this mode, users can set parameters like IP addresses, subnet masks, interface descriptions, and enable or disable the interface. To enter this mode, one typically starts from global configuration mode and selects the desired interface using the command interface [type] [number]. This mode allows for detailed and direct modifications to the behavior of network interfaces.

To configure a GRE tunnel, create a tunnel interface by issuing the interface tunnel command from the global configuration mode. To configure the tunnel source and destination, issue the tunnel source {ip-address | interface-type} andtunnel destination {host-name | ip-address} commands under the interface configuration mode for the tunnel.
In the interface configuration mode of a router, the command ip address dhcp enables the interface to acquire an IPv4 address automatically from an ISP via DHCP when the link to the ISP is enabled. This command instructs the router to request an IP address and other configuration information from a DHCP server. After issuing this command, ensure that the interface is also enabled with the no shutdown command.
On a Cisco router, that means that you entered interface configuration mode; any command you give will affect the selected interface. For example, you may have given the commands:Router>enableRouter#configure terminalRouter(config)#interface FastEthernet 1/0Router(config-if)#On a Cisco router, that means that you entered interface configuration mode; any command you give will affect the selected interface. For example, you may have given the commands:Router>enableRouter#configure terminalRouter(config)#interface FastEthernet 1/0Router(config-if)#On a Cisco router, that means that you entered interface configuration mode; any command you give will affect the selected interface. For example, you may have given the commands:Router>enableRouter#configure terminalRouter(config)#interface FastEthernet 1/0Router(config-if)#On a Cisco router, that means that you entered interface configuration mode; any command you give will affect the selected interface. For example, you may have given the commands:Router>enableRouter#configure terminalRouter(config)#interface FastEthernet 1/0Router(config-if)#

To configure a VLAN on a switch port, first access the switch's command-line interface (CLI) via console or SSH. Enter configuration mode by typing configure terminal, then select the specific interface using interface [type][number] (e.g., interface FastEthernet0/1). Assign the VLAN to the port with the command switchport access vlan [VLAN_ID], and if needed, set the port to access mode using switchport mode access. Finally, save the configuration with write memory or copy running-config startup-config.
