22.3 ARP Scanning Prevention Typical Examples
Figure 2-1 ARP scanning prevention typical configuration example
In the network topology above, port E1/1 of SWITCH B is connected to port E1/19 of SWITCH A, the port E1/2
of SWITCH A is connected to file server (IP address is 192.168.1.100), and all the other ports of SWITCH A
are connected to common PC. The following configuration can prevent ARP scanning effectively without
affecting the normal operation of the system.
SWITCH A configuration task sequence:
SwitchA(config)#anti-arpscan enable
SwitchA(config)#anti-arpscan recovery time 3600
SwitchA(config)#anti-arpscan trust ip 192.168.1.0 255.255.255.0
SwitchA(config)#interface ethernet1/2
SwitchA (Config-If-Ethernet1/2)#anti-arpscan trust port
SwitchA (Config-If-Ethernet1/2)#exit
SwitchA(config)#interface ethernet1/19
SwitchA (Config-If-Ethernet1/19)#anti-arpscan trust supertrust-port
