Airplay over Mobility Controller MSM760 in access control mode not working - Multicast DNS blocked?
Question:
How may we use our Apple TV devices over a VSC in тАЬAccess controlтАЭ mode
in a Mobility Controller MSM760 Teaming Evironment (Passthrough: Airplay, Bonjour, Multicast DNS)?
Scenario:
- Mobile Devices iPads and iPhones
- AccessPoints HP MSM460 in controlled mode
- Mobility Controller HP MSM760
- Teaming Mode (2 Controller)
- Software version: 5.7.2.0-sr2-12993
- Internet-Port with Egress VLAN (113) in the Internet Segment
- Apple TVтАЩs are connected by cable in the Egress VLAN (113)
- Apple TV uses Airplay service (see below)
- Internet-Port has
- untagged Management VLAN
- several tagged Egress VLANs
Airplay:
- Streaming music and video тАж
- Propagation by Airplay with Apples Bonjour Service
- Which use Multicast DNS (mDNS) protocol
- IP 224.0.0.251 and UDP Port 5353
Problem:
- Before change to тАЮAccess controlтАЬ Apple TV access was fine
- After change to тАЮAccess controlтАЬ (tunnelmode) no access!
- iPhones and iPads canтАЩt see any Apple TV device
- Airplay donтАЩt work - Broad-/Multicasts blocked!?!
Analyses/Tests:
- Team --> Security --> Firewall --> Firewall --> None = no success
- IGMP proxy enabled under Team ├а Team ├а Network
- No success
- Makes no sense тАУ client and server in same segment (VLAN)
- IGMP proxy already disabled
- VSC die тАЮWireless security filtersтАЭ toggled = no success
- Broadcast Filtering is off
In the CLI we see TX errors on Controller data tunnel
CLI# show interfaces
Interface State Dir Bytes Packets Dropped Errors Collisions
--------------------------- ----- ---- -------------------- ---------- ---------- ---------- -----------
Controller data tunnel Up Rx: 413321614 336459 0 0
Tx: 44123686 161033 0 13087 0 ├Я
Has anyone an idea?

Make sure you dont have any multicast or broadcast restrictions on the VSC and that the wireless and wired devices are in the same l2 segment, since bonjour cant be routed.

Re: Airplay over Mobility Controller MSM760 in access control mode not working - Multicast DNS block
There are none broadcast filter and wireless filter and global firewall switched on.
All components are connected to the same VLAN (L2 segment) - see above.
The mDNS (Bonjour) blocking starts with the change to "access control" mode, why?
The "access control" mode is necessary for operations in remote sites,
if you have no access to remote Access WAN Routers for building VRFs and
GRE tunnels or alternatively L2TPv3 tunnels. This methods need great effort.
With regards
Johannes

Re: Airplay over Mobility Controller MSM760 in access control mode not working - Multicast DNS block
Then I dont really know. All access controller environment Ive set up have been routed in the MSM controller, which instantly disables bonjour. But yours are bridget? Are you able to get through other kind of multicast?

br0 on the LAN-Port. Under CLI we detected some TX errors - see above.
It seems no multi-/broadcasts are passing after changing to "access control"
mode.
Other diagnostic Apps reports several neighbors before the change,
now the App sees only clients connected to the same wireless access point!

In VSC config for your SSID, under "Virtual AP" have you allowed traffic between client? It┬┤s configured to "no" by default.

Re: Airplay over Mobility Controller MSM760 in access control mode not working - Multicast DNS block
A long time ago there was a solution for AirPlay that involved setting the QoS for the VSC to "VSC-Based Normal" instead of "Diffserv". Give that a try.
