Hey again,

I managed to put a 7960 phone on the VLAN998 behind
the WGB wired switch. To register over the bridge link to a CME box
Configured for MOH via Multicast. I used a 7921 to call between
to test multicast MOH between. I could use the root to connect the 7921.
I tested this with one VLAN using the work-group bridge client vlan 998 command.

If people are interested in the configuration you can post me.

I am next going to try out LAB 3.9 that Vit mentioned. See if I can get it 
working.
But I don´t understand why people talk about workgroup-bridge client vlan 
command
in that perspective, because I don´t think it is of any use in this 3.9 lab. 
And the
question doesn´t seem to demand it. I haven´t looked at the DSG yet. I will
do that after I figure it out, of course! :D

regards. Kristjan

p.s

Interesting to see if I use the various workgroup-bridge multicast mode client 
or infrastructure
I get this message on the WGB console if I configure either way:

*Mar  2 00:14:05.486: %DOT11-6-MCAST_DISCARD: client mode multicast packets are 
discarded  in infrastructure mode  multicast mode

or :

*Mar  2 00:15:35.809: %DOT11-6-MCAST_DISCARD: client mode multicast packets are 
discarded  in infrastructure mode  multicast mode

with only workgroup-bridge mode. This log disappears.

Jason can you explain what this means for your traffic?

In this case, I had another excersise in mind from Jason´s bootcamp.

But I will be glad to look at 3.8 myself
and see If I understand it and post some thoughts :D

Hi Kristjan,

Firstly, many thanks for testing and sharing the configs!

Yes, this works perfectly well when you use 'bridge-group 1' associated with 
the Vlan998 on the root AAP :) Actually, even if you do not specify 'work clien 
998' on WGB, its interface BVI1 will still get an ip address from a DHCP server.

My issue arrises from Lab 3.8. According to requirements (or it is just my 
wrong understanding), Vlan 110 on the Root AP has to be associated with the 
bridge-group 1, because this is a management Vlan. The Lab 3.8 does not mention 
to use 'work client-vlan 11' on the WGB, I decided to go extra mile and got 
stuck.... Also, looked at the configs provided by Jason 
(http://onlinestudylist.com/archives/ccie_wireless/2011-March/002018.html), but 
they do not work for me.

May be I'm missing something... but can someone try the configs WGB-client 
taken from the link above please?

Hey Vitaly and group.

I labbed this up.

I got work-group bridge to work in "workgroup-bridge client vlan 998" mode
I started to get the root ap working with the wgb-04 ssid connected to VLAN 998
with DHCP server on a switch/router for the 10.10.98.0/24<http://10.10.98.0/24> 
subnet.

I´m using 2x 1242's in this setup and software version of 12.3.8 JEA3

I had one problem at first, this was after enabling infrastructure-client on 
the Root.
The WGB got Dhcp address through the bridge-link but no other traffic was 
working from the root.
It was fixed after rebooting the Root. Here are the configs on the WGB and 
Root. I made some fun
addons to this excercise that you can see in next post :D

Thanks Jason,

Yes, I see Root AP (and connected switch) native vlan packets arriving to the 
port on a switch connected  to WGB and I had to configure native vlan on this 
port to match the one on another side.... But no vlan 11 packets are arriving 
on the switch connected to WGB...

Kind regards,
Vitaly

Just to confirm - using the "workgroup-bridge client-vlan x" command requires 
the following:

1) Root AP has a subinterface with the specified VLAN (mapped to the required 
SSID)
2) If a switch is connected to the WGB, it must use a trunk.  The native VLAN 
should be the same as the native on the root AP (both wired and wireless.)  
Otherwise, STP will detect that it is receiving BPDUs for one "native" VLAN on 
a different "native" VLAN and block both.

But, as you said, lab it up :)

Hey Kristjan, thanks for your response.

Yes, I have a basic config on both root and WGB AAPs, e.g. auth open, ssid and 
that's it :) Assigning static address to wired WGB-client didn't help as well, 
so it's not DHCP-related issue. I had sub-interfaces configured on the Root 
AAP, e.g. d0.11, but I believe they needed, otherwise what's the point of 
having 'work clie 11' on the WGB. Could you please share a working config, I 
will test if it works with wired WGB-clients and you will practice speed ;o)

Thank you.

Vitaly

Hey Vitaly,

I tested this out in a lab recently. I reccon that the only command
need for the workgroup-bridge vlan x is needed. This will hide all
other stuff you would normaly do. for example int dot0.11 blablabla.
But with other stuff on the wire I didn´t test it but if the WGB was working
from wired, I suppose clients on the WGB VLAN should work too.

I find sometimes in cases with dhcp or other broadcast/multicast issues
the infrastructure-client command on the Root AP helps. After all
it is meant to deliver multicast (and broadcast ?) packets reliably..

Putting a static IP of course might help to isolate the problem to
start with and also to simplify security before troubleshooting the
DHCP related issues. I like to add the security stuff as the last step
to see all radio related stuff working first.

my 5 cents..

regards. Kristjan

Guys,

I've got a question regarding the 'workgroup-brdige client-vlan X' command
and Jason's post ->
http://onlinestudylist.com/archives/ccie_wireless/2011-March/002018.html

Has anyone managed to get WGB with client-vlan working, e.g. wired clients
connected to the WGB are able to get ip address from a DHCP server and ping
the rest of the world through the wireless link between Root and WGB? When I
create d0.11 subinterface on the WGB, then everything works, once I delete
d0.11 (and reboot the WGB to remove Virtual-Dot11Radio0.11) and apply 'work
clie 11' then wired clients register on the Root AAP but do not get ip
addresses... Yes, I  also applied 'bridge 11 proto ieee' to WGB, but no
joy...

Any help will be much appreciated.

Regards,
Vitaly
