When the IP mode is set to v4-prefer mode, the IAP derives a link local IPv6 address and attempts to acquire a
routable IPv6 address by monitoring Router Advertisements (RA) packets. IAP assigns itself to both Stateless
address autoconfiguration (SLAAC) and DHCPv6 client address. IAPs also support IPv6 DNS server addresses
and use these for DNS resolution.
In the CLI:
To enable IPv4 mode or dual stack mode:
(Instant AP)(config)# ip-mode {v4-only|v4-prefer}
(Instant AP)(config)# end
(Instant AP)(config)# commit apply
Configuring IPv6 Address for an IAP
You can enable the IPv6 mode on the IAP and also configure a VC IPv6 address using the Instant UI or the CLI:
In the Instant UI:
To enable IPv6 and configure VC IPv6 address:
1. Go to the System link, directly above the Search bar in the Instant UI.
2. Under General, select the Allow IPv6 Management check box.
3. Enter the IP address in the Virtual Controller IPv6 address text box.
4. Click OK.
In the CLI:
To configure an IPv6 address for an IAP:
(Instant AP)(config)# virtual-controller-ipv6 <ipv6 address>
(Instant AP)(config)# end
(Instant AP)# commit apply
The VC IPv6 address can be configured only after enabling the v4-prefer mode in the Instant CLI.
RADIUS over IPv6
With the address mode set to v4-prefer, the IAP supports an IPv6 IP address for the RADIUS server. The
authentication server configuration can also include the NAS IPv6 address (that defaults to the routable IPv6
address when not configured).
To configure an IPv6 address for the RADIUS server:
(Instant AP)(config)# wlan auth-server radiusIPv6
(Instant AP)(Auth Server "radiusIPv6")# ip <host>
(Instant AP)(Auth Server "radiusIPv6")# nas-ip <ip_ipv6>
(Instant AP)(Auth Server "radiusIPv6")# end
(Instant AP)# commit apply
SNMP Over IPv6
In this release, you can configure a community string to authenticate messages sent between the VC and the
SNMP agent, where the IPv6 address will be used as the VC address.For more information on configuring
SNMP parameters, see
To view the SNMP configuration:
