DHCPv6 relay - "interface is not on"?

[flic]

Hi.

I'm trying to configure DHCPv6 relay for a few interfaces. One of the interfaces works perfectly, but three others doesn't work at all.

On the interface where the relay is working I can see the traffic flow in the traffic log, but on the interfaces where it doesn't work I see nothing at all in the log. I log all dropped packages.

I ran a packet capture on all stages on one of the non-working interfaces, and I can see that the firewall receives the DHCPv6 packet on ff02::1:2 from the client in the receive stage, but I can't see it in the firewall stage or any other stage.

I found something interesting in the dhcpd.log:

May 23 13:28:27 pan_dhcp6_handle_packet(pan_dhcp6.c:94): receive packet on interface 267 length 36 message type 11

May 23 13:28:27 pan_dhcpd_relay6_handle_packet(pan_dhcpd_relay6.c:156): interface ethernet1/5.1023 is not on

(I found similar messages for the other interfaces)

What does it mean that the interface "is not on"?

All other traffic works, including a DNS proxy on the same interface.

We are working on this issue where when multiple sub interfaces are configured for DHCPv6, only one sub interface works. Please open a case with Support or your reseller to get further details/updates on this issue.

Thank you, I'll do that.
