1.2.4 IP ACL Example
Configuration requirements:
There are two devices Switch A and Switch B, as shown in Figure 3:
Figure-3 Basic Access List Example
It is required to implement the following security functions by configuring access lists
on Switch B.
1. Hosts at the 192.168.12.0/24 network section can only access the remote UNIX
host TELNET service during the normal working time period and deny the PING
service.
2. On the Switch B console, access to any of the services of hosts at the
192.168.202.0/24 network section is denied.
Note
The above case simplifies the application in the bank system. Namely,
it only allows the hosts on the Local Area Network of branches or
savings agencies to access the central host and disallows accessing
the central host on the device.
Equipment Configuration
Switch B configuration:
DES-7200(config)# interface GigabitEthernet 0/1
DES-7200(config-if)# ip address 192.168.12.1 255.255.255.0
DES-7200(config-if)# exit
