2911, IPv6 and EHWIC Switch (EHWIC-D-8ESG-P) = FAIL?

Hi,

I'm currently running a 2911 with POE PSU and a EHWIC-D-8ESG-P to support my phones. But I don't get IPv6 to work 100%.

IPv4 Looks fine.

IPv6 ping from router to everything is fine.

IPv6 ping from device connected to switch module to other device on that switch doesn't work.

IPv6 ping from device connected to switch module to anything else works fine.

Seems like some traffic from one port to another is restriced...

That enables phones to call to remote sites via IPv6 but NOT to their neighbor - signalling to CUCM works, but the RTP doesn't hit the destination.

What I have:

interface GigabitEthernet0/0

no ip address

duplex auto

speed auto

bridge-group 1

bridge-group 1 spanning-disabled

interface GigabitEthernet0/1

ip pim sparse-dense-mode

interface GigabitEthernet0/2

no ip address

This seems like CSCtt61762 but I'm running IOS 15.3(1)T where it should be fixed in ...

I do not have a service contract so I can't raise a SR...

Cheers,

Michael
