Stateless Address Autoconfiguration
In stateless address autoconfiguration, the AQ1300/AQ1301 sends a router solicitation message to the
router and uses the router advertise message that it receives to set the source IPv6 address.
Ignored RAs
The following RAs are not recognized as RAs when they are received.
• RAs with an MPLS label attached
• RAs with an LLC/SNAP header attached (only RAs that conform to the DIX specification are
supported)
• RAs that are counted as errors
• RAs that are received at the same time that a linkdown occurs
• RAs that are received at the same time that a collision occurs
• RAs whose packet lengths are less than 81 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.
• RAs with three or more VLAN stacks.
Automatic MAC Address Acquisition through NDP
In automatic MAC address acquisition through NDP, the AQ1300/AQ1301 uses NDP (neighbor
discovery protocol) message processing at the start of testing to automatically obtain the MAC address
of the IPv6 target host and then uses that address as the frame destination MAC address.
Automatic MAC Address Acquisition Conditions
• When automatic acquisition is enabled, MAC address acquisition through NDP is performed with
the specified target host (IP address) at the start of measurement. If the target host is not in the
same segment as the AQ1300/AQ1301 from the prefix length, MAC acquisition is performed with
the IPv6 router.
(Acquisition is performed before measurement starts. Afterwards, the statistics are cleared and
measurement starts.)
• The AQ1300/AQ1301 waits for a reply after it sends an NS (neighbor solicitation) packet. The
timeout value is 1 second. The AQ1300/AQ1301 will try again after timing out.
• The acquired MAC address is cleared at the start of the next test.
• If the MAC address increment feature is enabled, it has priority.
• If the variable field feature is enabled, it has priority.
