WiSM and IPv6 provisioning

[with_joerg]

All,

we have migrated from WLSM to WiSM (4.0.179.11). To enable IPv6 for the clients on the WLSM it was enough to give either the VLAN-if or the tunnel-if a valid IPv6 address and the attached clients had the possibility to retrieve an IPv6 address via auto-discovery.

With the WiSM we need to enable IPv6 provisioning in the WLAN configuration screen. But the clients associated to this WLAN then still cannot discover a vaild IPv6 address. Is there anything more we need to do? I mean, the functionality was perfect with the WLSM ... ... .

How can I debug? There seems to be no documentation on that. Pls help.

Hello Joerg,

I would say that if the DHCP server is correct on the interface tied to that WLAN then you should be good.

For debugs,I would capture:

debug dhcp packet enable

debug dhcp events enable

From this output we should be able to determine the issue.

Regards,

Aaron

Hello Aaron,

we tried IPv6 auto discovery and static IPv6 addresses. Both did not work with the WiSM. They did work with the WLSM though.

Then I discivered that it starts working if I go to CONTROLLER and set "Ethernet Multicast Mode" to "Unicast". I see not why this is though and wether it is intended behaviour in terms of IPv6 or not.

Since we need to have a stable IPv6 network platform I need to find this out.
