【 Weak current College 】 router application examples how to configure an Ethernet interface-Power By 【 China power house network 】

In the configuration of the Ethernet interface, we need to configure the Ethernet interface IP address and subnet mask for the IP address of the packet.　　By default, the Ethernet interface is administratively closed, so the IP address configuration is complete, we also need to activate the interface.　　Configuration example: in this instance, we need to configure the Ethernet interface of the IP address 192.168.0.1 and activation interfaces.　　1, in privileged mode to enter the global configuration mode.　　Router # configure terminal 2, enter the first Ethernet interface.　　Router (config) # interface e 0 3, then the command prompt changes to router (config-if) #, at the prompt enter the following command to configure the interface for the private IP address of 192.168.0.1, with a default subnet mask of 255.255.255.0.　　Router (config-if) # ip address 192.168.0.1 255.255.255.0 4, default, cisco router's interface is in the off State, we need to type "no shutdown" command to activate the interface. Router (config-if) # no shutdown for Cisco routers assign multiple addresses we can pass on an interface to configure multiple IP addresses to resolve address allocation and connect more subnets problem, for example: in the user's network requires 280 IP addresses, we can provide an interface on the router to assign multiple IP addresses to increase available for allocation of address range. In the Ethernet interface configuration mode, enter the ip address 192.168.1.1 255.255.255.0 "" command to increase the range of IP addresses to 506. So we can resolve the IP address allocation problem!
