7.8 Martian 
Filtering 
It is possible to block packets, which trying to bring different source IP out from same 
network. If packet brings different IP address, not its source IP address, then it is impos-
sible to know it makes a trouble. Therefore, you would better prevent this kind of packet 
outgoing from your network. This function is named as Martian filter. 
To block packets which try to bring different source IP out from same network, use the fol-
lowing command. 
Command Mode 
Description 
ip martian-filter
 INTERFACE Global 
Blocks packets which bring different source IP address 
from specified interface. 
INTERFACE: enter the interface name. 
 
It is not possible to configure both QoS and Martian filter at the same time. 
To disable the configured Martian filter function, use the following command. 
Command Mode 
Description 
no ip martian-filter
 INTERFACE Global 
Disables a configured Martian filter function. 
INTERFACE: enter an interface name. 
 
To see a configuration of Martian filter, use the show running-config command. 
 
7.9 Max 
Host 
You can limit the number of users by configuring maximum number of users also named 
as max hosts for each port. In this case, you need to consider not only the number of PCs 
in network but also devices such as switches in network. 
For the hiD 6615 S223/S323, you have to lock the port like MAC filtering before configur-
ing max hosts. In case of ISPs, it is possible to arrange billing plan for each user by using 
this configuration. 
To configure max host, use the following command.
