Index
• ARP replies that are received at the same time that a collision occurs
• ARP replies whose packet lengths are less than 63 bytes, greater than 1519 bytes (greater than
1523 when there is one VLAN stack or greater than 1527 when there are two VLAN stacks), or
greater than the oversize threshold.
• ARP replies with three or more VLAN stacks.
Automatic IP Address Acquisition (DHCP)
In automatic IP address acquisition, the AQ1300/AQ1301 requests an address from the DHCP server
and then uses the acquired IPv4 address as the source IPv4 address.
Multi Host
If the test menu is set to Manual and the test layer is IPv4, this feature automatically generates multiple
MAC addresses from the VLAN ID or IP address information and make the AQ1300/AQ1301 emulate
multiple hosts in the VLAN.
• Returns ARP replies as a multi host.
• Automatically performs ARP acquisition of frame destination MAC addresses for each QoS channel
in Qos test mode. This feature also automatically generates frame source MAC addresses.
• Automatically configures Rx QoS filters for each QoS channel in QoS test mode.
IPv6 Host
NDP Reply
In NDP (Neighbor Discovery Protocol) replying, the AQ1300/AQ1301 resolves the address by sending
an NA (Neighbor Advertisement) when it receives an NS (Neighbor Solicitation). When you enable
NDP, it is always enabled regardless of the test mode setting, filter condition, or transmission condition.
When Auto or Auto(Remote) has been selected in the Test menu, NDP replying is always enabled.
When Manual has been selected in the Test menu and the test layer is L3-IPv6, you can configure
NDP replying by specifying the emulation settings.
NSs That Are Not Answered
The AQ1300/AQ1301 will not send an NA in response to the following kinds of NS.
• NSs with an LLC/SNAP header attached (only NSs that conform to the DIX specification are
supported)
• NSs with an MPLS label attached
• NSs that are counted as errors, except for payload and sequence errors
• NSs that are received at the same time that a linkdown occurs
• NSs that are received at the same time that a collision occurs
• NSs whose packet lengths are less than 81 bytes, greater than 10000 bytes, or greater than the
oversize threshold.
• NSs with three or more VLAN stacks.
VLAN Tag Handling
The AQ1300/AQ1301 sends NAs in response to NSs with VLAN tags attached.
NDP Requests with Test Tags
The AQ1300/AQ1301 sends NDP replies in response to NDP requests with test tags attached.
