Addressing Questions
Question
: How do I configure the computer to use one MAC address per host?
Answer
: If you edit the Network Neighborhood selected for your test, you can select 'Host' as the type
for the domain. This will allot one MAC address per host. Selecting 'Virtual Router' uses one MAC
address total for all traffic from that subnet.
Question
: Why would I want to use one MAC address for all hosts?
Answer
: A device has limited memory dedicated to its ARP table. If it takes too long for the ARP table
to populate, the device may run out of buffer packets for that host and drop packets. So, you will want
to use the 'Virtual Router' option when using more addresses than the device’s ARP table is capable of
handling. Otherwise, entries are dropped before they need to be used.
Question
: Can NAT be used across multiple test components?
Answer
: No. Only one test component can use a domain that has NAT turned on. Any domain that has
NAT tuned on cannot be shared between test components.
Question
