In release BOSS 4.2 for the ERS5510, you can enable ARP Spoofing Detection via the WEB
interface or by using a CLI command as shown below.
CLI
• 5510-48T(config)#interface fastEthernet <ALL|port|slot/port>
• 5510-48T(config)#qos arp spoofing [port <port_list>] enable default-gateway <a.b.c.d>
where
Parameter Description
port <port_list> The list of ports to enable QoS ARP spoofing application
on.
default-gateway <A.B.C.D> The IP address of the default gateway to use.

在支持三层交换的版本里面，命令有所更新，在需要防止欺骗的vlan里面做，建议每个vlan都做


ES 8600 with R-Modules:
Assuming:
• The default gateway is 10.1.25.1
• The user ports are ports 4/25-4/27
NOTE: The items high-lighted in red in the configuration file below is the default gateway address
