ewc@9130axi (c9800) + Sonos grouping

dear community,

 

I have a lab env. and facing problems with Sonos grouping - see details:

- Using ewc @c9130axi (v 17.3.1)

- Using two Sonos device

   - Sonos BEAM

   - Sonos SUB

- AP is Flex mode due to ewc

 

BEAM and SUB are both connected to wifi and are reachable (visible on WLC & IP is fine)

Once I am trying to add  SUB to a Group with BEAM, my Sonos App on my mobile is showing up "Livingroom (+?)"

 

I was wondering there might be a problem with multicast/unicast - but after couple of hours I figured out, that the SUB is not getting an IP after grouping.

 

Radioactive Trace is giving me this: (see bold line)

So how could this happen? this must be something with the wlc and/or 9130axi.

Can not really follow, why device is dropping - without grouping, dhcp is working fine.

 

If I am changing over to my productive wireless (non-cisco & enduser equipment) - the sonos grouping is working fine.

 

I can also see in a wireshark capture the packets from SUB - see attached screenshot.

 

any ideas about this?

 

EDIT: 

found these information during my research:

I don't know the EWC very well, but I see that you use a VLAN 1 and a VLAN 4. Which should the sub get and which IP range is defined for that VLAN?

I was curious about that log entry for VLAN 4 - because this VLAN does not exist.

Only using VLAN 1 (all access - no tagging). The internal IP Range is 10.1.1.0/24 

 

in the log you can see the sub is getting "10.1.1.245" - i mean depending on this line:

11:35:47.998259 {wncd_x_R0-0}{1}: [sisf-packet] [9659]: (info): RX: DHCPv4 from interface capwap_90000005 on vlan 1 Src MAC: 04eb.409e.4xxx Dst MAC: ffff.ffff.ffff src_ip: 10.1.1.15, dst_ip: 255.255.255.255, BOOTPREPLY, SISF_DHCPOFFER, giaddr: 10.1.1.15, yiaddr: 10.1.1.245, CMAC: "MacAddressOfSUB"
