The IP address is added.

To edit an IP address, click the edit icon (

). To delete an IP address, click the delete icon (

).

When adding an IP address to a routed interface of a clustered device, you must add a 
corresponding IP address to the routed interface on the cluster peer.

To add a static ARP entry, click 

.

The Add Static ARP Entry pop-up window appears.

In the 

 field, type an IP address for the static ARP entry.

In the 

 field, type a MAC address to associate with the IP address. Enter the address using 

the standard format of six groups of two hexadecimal digits separated by colons (for example, 

01:23:45:67:89:AB

).

Click 

.

The static ARP entry is added.

To edit a static ARP entry, click the edit icon (

The physical routed interface is configured. Note that your changes do not take effect until you apply the 
device configuration; see

Control

Series 3

For each physical routed interface, you can add multiple logical routed interfaces. You must associate 
each logical interface with a VLAN tag to handle traffic received by the physical interface with that 
specific tag. You must assign a logical routed interface to a virtual router to route traffic.

Note that disabling the 

 option for routed interfaces does not prevent ICMP 

responses in all scenarios. You can add rules to an access control policy to drop packets where the 
destination IP is the routed interface’s IP and the protocol is ICMP. For more information about creating 
access control rules, see 

. If you have 

enabled the 

 option on the managed device, it drops the packets before they 

reach the host, thereby preventing any response. For more information about inspecting local router 
traffic, see 

.

Changing the maximum transmission unit (MTU) interrupts traffic on the device and packets are 
dropped. The range within which you can set the MTU can vary depending on the FireSIGHT System 
device model and interface type. See 

 for more 

information.

To edit an existing routed interface, click the edit icon (

) next to the interface.
