 Additional Configurations

   Configuring the Driver on Different Distributions
   -------------------------------------------------
 
-  Configuring a network driver to load properly when the system is started is 
-  distribution dependent. Typically, the configuration process involves adding 
-  an alias line to /etc/modules.conf as well as editing other system startup 
-  scripts and/or configuration files.  Many popular Linux distributions ship 
-  with tools to make these changes for you. To learn the proper way to 
-  configure a network device for your system, refer to your distribution 
-  documentation. If during this process you are asked for the driver or module 
-  name, the name for the Linux Base Driver for the Intel PRO/100 Family of 
-  Adapters is e100.

+  Multiple Interfaces on Same Ethernet Broadcast Network
+  ------------------------------------------------------
+
+  Due to the default ARP behavior on Linux, it is not possible to have
+  one system on two IP networks in the same Ethernet broadcast domain
+  (non-partitioned switch) behave as expected. All Ethernet interfaces
+  will respond to IP traffic for any IP address assigned to the system.
+  This results in unbalanced receive traffic.

+  If you have multiple interfaces in a server, either turn on ARP
+  filtering by
+
+  (1) entering: echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+      (this only works if your kernel's version is higher than 2.4.5), or
+
+  (2) installing the interfaces in separate broadcast domains (either
+      in different switches or in a switch partitioned to VLANs).
