Layer three switch-routing-hardware firewall configuration

The port itself is turned on by default, but does not mean that the link to the port must be up. Only link devices are connected and connected devices such as PC are working properly ...

Three-layer switch port, still have 24, or fa0/1-24, its three-tier routing function is not implemented through the FastEthernet port, but through its VLAN interface to achieve,

therefore, on the two two-layer switch of unicom, it is necessary to configure VLAN to realize interoperability. Accordingly, the export of the two-layer switch will be set to trunk.

Number of ports and gateway IP addresses for the two-tier switch?

General two-layer switches in front of the port: f0/1-23: As a normal port, used to connect the PC, the last port f0/24 is generally used as a port to connect the three-tier device.

and the gateway IP address, also with the last maximum that number: 254来: 192.168.10.254 255.255.255.0

Note: When representing multiple ports, do not forget the keyword: int range f0/1-3
