Click Save. The changes are saved to the Startup Configuration.
NOTE
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.

IPv6 Tunnel
The WAP371 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.
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.
The WAP device acts as an ISATAP client. An ISATAP enabled host or router must reside on
the LAN. The IP address or hostname of the router is configured on the WAP device (by
default, it is isatap). If configured as a hostname, the WAP device communicates with a DNS
server to resolve the name into one or more ISATAP router addresses. The WAP device then
sends solicit messages to the router. When an ISATAP-enabled router replies with an
advertisement message, the WAP device and router establish the tunnel. The tunnel interface is
assigned a link-local and a global IPv6 address, which serve as virtual IPv6 interfaces on the
IPv4 network.

To configure an IPv6 tunnel using ISATAP:
STEP 1
Select LAN > IPv6 Tunnel in the navigation area.
STEP 2
Configure the following parameters:
•
ISATAP Status—Enables or disables the administrative mode of ISATAP on the WAP
