Cisco Small Business WAP551 and WAP561 Wireless-N Access Point
• Static IPv6 Address Prefix Length—The prefix length of the static address, which is an
integer in the range of 0 to 128. The default is 0.
• Static IPv6 Address Status—One of the following values appears:
- Operational—The IP address has been verified as unique on the LAN and is usable
on the interface.
- Tentative—The WAP device initiates a duplicate address detection (DAD) process
automatically when a static IP address is assigned. An IPv6 address is in the
tentative state while it is being verified as unique on the network. While in this state,
the IPv6 address cannot be used to transmit or receive ordinary traffic.
- Blank (no value)—No IP address is assigned or the assigned address is not
operational.
• IPv6 Autoconfigured Global Addresses—If the WAP device has been assigned one or
more IPv6 addresses automatically, the addresses are listed.
• IPv6 Link Local Address—The IPv6 address used by the local physical link. The link
local address is not configurable and is assigned by using the IPv6 Neighbor Discovery
process.
• Default IPv6 Gateway—The statically configured default IPv6 gateway.
• IPv6 DNS Nameservers—Select one of the following values:
- Dynamic—The DNS name servers are learned dynamically through DHCPv6.
- Manual—You specify up to two IPv6 DNS name servers in the fields provided.
Click Save. The changes are saved to the Startup Configuration.
After new settings are saved, the corresponding processes may be stopped and restarted. When
this happens, the WAP device may lose connectivity. We recommend that you change WAP
device settings when a loss of connectivity will least affect your wireless clients.
The WAP551 and WAP561 devices support the Intra-Site Automatic Tunnel Addressing
Protocol (ISATAP). ISATAP enables the WAP device to transmit IPv6 packets encapsulated
within IPv4 packets over the LAN. The protocol enables the WAP device to communicate with
remote IPv6-capable hosts even when the LAN that connects them does not support IPv6.
