1300 Root-Bridge and Non-Root Bridge setup

I have two 1300s that I am trying to set up as Root Bridge and Non-Root Bridge, however, everytime i specify one of them as a Non-Root bridge, the radio0 interface becomes disabled. The only option that i am able to pick that enables the radio0 interface is "Access Point", which is what am trying to avoid it being.
Can anybody help me figure out how to go about this

A non-root's radio will show as disabled if it cannot find the root AP to associate to. Make sure you have "infrastructure-ssid" configured under the SSID on both the root and non-root bridges. Also depending on code versions you may have to configure the distance command under the radio interface on the root.

Root-Bridge and Non-Root Bridge Support

I was wondering if the ISR Routers (Cisco 1811w) support the root-bridge and non-root-bridge feature. If not is there another device apart from the 1310 and 1410 bridges that support this feature?
Thank You,
VT

Hi VT,
The ISR AP supports both of these roles;
Access Point Link Role Flexibility
Access Point Link Role Flexibility allows access point radios to operate in a combination of radio roles,
such as access point root, bridge root (with or without clients), bridge nonroot (with or without clients).
This provides a more flexible deployment scheme to support the various applications requirement. Note
that the ISR AP does not support access point repeater and WGB.
Wireless Non-Root Bridge
The wireless non-root bridge allows the access point radio to operate as the remote node in a point to
point or point to multi-point network.
Wireless Root Bridge
The wireless root bridge role provides support for both point-to-point or point to multi-point bridging.

Cannot Associate 1532 Bridges in Non-Root role

Hello,
Can someone please tell me what I am missing and why I cannot bring up 2 bridges in "Root" and "Non-Root" roles?
I have similarly configured bridges in a Root / Non-Root role several times before with older AP's and never had any issues... although it was always just 1 SSID, 1 Vlan, and no subinterfaces...
The only way I was able to get these 2 bridges to associate was to put the Non-Root bridge into a Workgroup Bridge role and then *BANG* everything worked perfectly. I tried getting rid of the authentication and tried using the Parent command but neither helped. Prior to entering Station Role Workgroup Bridge, the only message I would receive was showing on the Non-Root side and all it said was:
*Mar 1 07:27:13.867 GMT: %DOT11-4-CANT_ASSOC: Interface Dot11Radio0, cannot associate: No Response
*Mar 1 07:27:28.891 GMT: %DOT11-4-CANT_ASSOC: Interface Dot11Radio0, cannot associate: Rcvd response from 544a.0005.8030 channel 3 2815
What am I missing or what have I incorrectly configured on my Non-Root config?
Bridges are both 1532i with the Autonomous Image 15.2(4)JB5
Attached are the configs prior to changing the Non-Root AP to a station role of Workgroup Bridge.
Thanks!

Hi,
This should work with multiple sub-interfaces.
Few more suggestions
1. Remove this from your BRIDGE SSID & check
mobility network-id 1
This is only require when you configure L3 roaming & WDS in place.
http://www.cisco.com/c/en/us/support/docs/wireless/aironet-1200-series/8103-ap-faq.html
2. Try to set WPA version 2 & only AES encryption.
Also try to Associate your Bridges using Open Auth first (as shown in my blog post initial section) & then try to add security.

1242 as Root and Non Root

Hi Everyone,
I am setting up pair of 1242 APs as Root and Non-Root bridge, i am not able to find the Install Mode on the 1242 AP while setting the Non Root for Best signal.
any help will be appreciated.
HM

Hi HM,
AFAIK, we do not have the INSATALL mode on the 1242 AP if we are using it as ROOT and NONROOT.. this is available only on 1310 bridge or 1410 bridges.. not on 1242AP..
lemme know if this answered your question..

Hi,
there seems to be something wrong with your network configuration (either on server, or in the vm configuration).
Pls. also next time update what version you are using. Based on the path to the repository I believe it is 3.0.X
Easiest will probably be to simply use the manager and edit the network setting of the VM (network device/bridge) there.
If error continues to exists, please post your network setup of the server (ifcfongi -a and brctl show) and post the vm.cfg
Regards
Sebastian

Network Design - Root and Non root bridges

Hi,
We have a network set-up as the below image. Where the switches have STP enable to handle the muliple paths for the data to flow.
What I would like to know is should the 2 bridges plugged into the same switch e.g Switch A (Bridge A and Bridge B) both be root bridges and (Bridge C and Bridge D) both be non root.
Or should for example, Bridge A be a root and Bridge C a non root and Bridge B a non root and Bridge D the root?
Similarly with the rest of the other bridges E, F, G and H
Thanks

Ah, I think I understand. So the wireless bridges are "transparent" to the rest of the network. They just convert wired to wireless and back again.
If I have that right, we can ignore them and just consider your switches.
In that case, it appears you have two L2 loops, those formed by the dual paths between switches A and B and between switches C and D. From a topology standpoint, it doesn't seem to matter what switch you select as root and secondary root. However, as switches B and C are the interior switches, I would suggest those as your root and secondary root switches.

1310 Root with two non-root bridges

I have a Cisco 1310 root bridge and a 1310 non-root bridge . it worked fine for a year, I then installed one more 1310 as a non-root bridge now I?m seeing both of my non-root bridges dropping offline more and more. I checked my first non-root bridge today and the radio is down and I can?t seem to bring it back up. I have recently upgraded the tar to see if that would fix the problem. This problem started when I added my second non-root bridge. Did I miss some setting or something

Make sure the spanning tree protocol is disabled on Vlan interfaces

In iPS 3.0SP3a, I would like to change the super-admin entry from root to a non-root user. The problem is I was able to install iPS as a pseudo-root however console will not let me in as that.

There must be a way to do this. Pls help.

Hi,
Please Check whether the said unix user is already existing under any roles of the default-domain.
If so, delete the user from that role in the default_domain and then
Goto : Manage Domain > view Domain Administrator Roles > Admin Role > users
Create the non root unix user name .
Once you create the user profile for this under the role defined for super admin,you can access as super admin.

Pretty gtk2 as root, ugly as non-root? [/SOLVED]

Heh, this is actually a little bit interesting. I've never ran anything that requires X as root until just a few minutes ago and realized that running applications such as pidgin and firefox as root, they are significantly prettier than what it looks like when I run it as non-root, even with the same gtk2 theme as you can see in the picture above. Oh, by the way, can you guys which one is my non-root and root running the above? The left is as non-root and the right is as root. See? A lot prettier... And I always questioned why Firefox was so damn ugly on Linux. It looks like it is suppose to as root.
Anyhow, I am curious on either what my non-root account is lacking (I think it is lacking the ability to read certain files), how could I configure it to look like what it does on root, or so on whatever the deal is. To me, this is just crazy. Heh, I am not saying how it looks is totally important, I've always been a fan of usability which is why I use dwm and stuff, but this is just crazy to me, lol, crazy...
Yeap.. So any ideas what I am doing wrong, missing, so on, lalala?
Edit: Blah, I feel like a fool. I played around with it more and realized it was clearlooks on root. My bad my bad my bad. :\ Well, at least y'all know what theme I'll be using. 8D
Last edited by Aprz (2009-04-20 11:35:42)

how are you selecting the gtk theme as non-root? also, which DE/wm are you using?

Root bridge and Non rootbridge as backup link (point to Point)

I want to use 2 APs as backup link. I want to be sure that this wireless link is working fine as a backup.
In order to avoid loops, Should I set any specific configuration in both APs?

Mixing and exporting for more than 8 channels and non-standard multichannel setups

I am trying to do something kind of unconventional, although I have seen people on the forums trying to do similar things. Unfortunately, it's unclear if they succeeded or not, and if they did, how.
I'm trying to figure out how to mix sound for an environment that has many (somewhere between 8 and 16) independent speakers, all connected to an audio interface. I know that WAV, AAC, and other audio file formats can carry that many channels and I can map them to the individual speakers. My question is how to edit/mix. Specifically,
Is this possible in Audition? It seems like it might be in CC, but not previous? (I have CS6.)
How do you set up the project file. When I create a new multitrack project, I can choose mono, stereo, or 5.1. The 5.1 option allows me to assign sounds to the five speakers in a standard 5.1 setup and the LFE. Is it possible mix for an environment with more than that? Or with a different configuration of speakers? In Audio MIDI Setup (for Windows people, that's where in OSX you set the more advanced audio preferences) I can configure up to 7.1 as well as geometric arrangements like quadrophonic, hexagonal, and octagonal. Is it possible in Audition to mix for anything like these?
There have been some threads where people talk about using 16 discrete outputs in Audition. How is this possible? Is each track able to be routed to a different output? If so, is it possible to write a file that has all of these tracks assigned to their discrete output channels?
Is it possible to nest audio sessions like you can nest Premiere sequences? For example, can I create a multitrack project with mono output and have that session be embedded into another multitrack session or do I have to finish editing the first one and write a file from it to use it in another project? Can buses be used to do this? What I'm wondering is if what I describe in #3 above IS possible, then how to have more than just a single pre-made audio file going to each of the outputs, to allow me to mix each channel with various sounds.
Sorry that's a few questions, but they all revolve around how to work with multi-channel sound that isn't stereo or 5.1.
Thanks!

As you have probably gathered, this is effectively a work in progress...

Is it possible in Audition to mix for anything like these?
At present, this is restricted to what you can see, but there's sort-of a workaround - albeit not an ideal one...
There have been some threads where people talk about using 16 discrete outputs in Audition. How is this possible? Is each track able to be routed to a different output? If so, is it possible to write a file that has all of these tracks assigned to their discrete output channels?
If you have a multichannel sound device, and all the outputs are visible to Audition, then yes, each track can be assigned directly to a different output. And if you set one up, you can do this with buses as well...
Is it possible to nest audio sessions like you can nest Premiere sequences? For example, can I create a multitrack project with mono output and have that session be embedded into another multitrack session or do I have to finish editing the first one and write a file from it to use it in another project?

What I'm wondering is if what I describe in #3 above IS possible, then how to have more than just a single pre-made audio file going to each of the outputs, to allow me to mix each channel with various sounds.
It's not possible to nest sessions at present in any version, and this has been asked about before. There are some significant issues with this, mainly to do with things like sample rates, output formats, etc. Doesn't mean that it won't happen, but don't hold your breath... As I said, there's a workaround, and yes, it's buses. Since you can effectively submix to a bus, and the bus output can go directly to hardware, then you can do what you want. The compromise is that in order to save the overall result, you'll end up with all of your source files, and a session file. And you'll have to play the whole thing back in Audition, rather than export it to a single file and be able to play it on a multichannel player. But yes, it should work.

      I have two buidlings acroos the street from each other. I have two Cisco Aironet 1250 wireless AP's with the first one going in the main building with network backbone. The Second AP goes across the street with the other wired network segment. Both AP's have long range antenas 2.4 GHZ on top of each building. I have configured the 1st one as the Root Bridge. The one across the street is configured as non-root bridge. I have both AP's configured with the same WEP key and also with the same SSID name with both set to broadcast it.   I am still unsure and confused as to how I get the non-root bridge to talk to and use the root bridge to get on the main network.
        1- It’s main to use the Root parent Mac address.
        2- Is there another config that I am missing to get the signal?
Note: I still not getting any signal from the root although distance between root and non-root is 330m
My root antenna is AIR-ANT24120 and non-root antenna is AIR-ANT1949 and attached files is my configuration files
Thank you.

1. How are the AIR-ANT24120 and the AIR-ANT1949 installed?
the AIR-ANT24120 is connected virtically on tower far 11m from the earth and AIR-ANT1949 is connected horizontally on tower far 10m from the earth
2. What is the distance between both APs?
350 m
3. Do you have clear line-of-sight between the two?
there is one tanker in the middle between them but it's far 7m from the earth
4. Is the two APs properly aligned?
i think yes and changed the aligned many times without any news (I don't have any tools for alignment)
5. Which point are the antennas connected to? Primary, Secondary or middle?
I tried in the primary and secondary but never tried the middle antenna
Thanks

7920 associates to root bridge but not to non-root bridge

I have 7920s using open authentication with WEP128 cipher. I have two 1300 root AP's (with client support) and three non-root AP's (also client support) in the same lab area. The root AP's and non-Root AP's associate and link to each other no problem. However, the 7920's will only associate with the Root APs. If I power down the root APs, the 7920s show "no AP found". I've verified SSID and WEP128 keys. I've also noted that the root AP does have a channel specified under dot11radio0 but the non-roots do not. Do the 7920's just scan for any channel until it finds an association or do I need to specify a channel in the non-root bridges?
Thanks,
Mike.

With static WEP, the authentication is happening at the AP level. Will want to ensure non-root is associated to a root though otherwise the interface may be in "reset" state.
The 7920 will look at these 2 as individual APs regardless of channel. Non-roots should have the same channel as the root, otherwise will not be able to communicate.

1310 Root Bridge will not Authenticate with 350 Non Root Bridge

I've exhausted myself solving this issue.
I have a 1310 set as a root bridge using WEPS. I have a 350 set as a non root bridge/without clients, also using WEPS (they both use the same SSID)
The 350 will not authenticate to the 1310. After doing a Carrier Busy Test, it is clear the 350 see's the 1310 with signal strengh of 100 percent.
(I have a test lab setup in my office)
If I make the 350 the Root Bridge and the 1310 the Non Root, The 1310 will authenticate to the 350.
I hoping someone else has seen this problem and can enlighten me.
Thank you.

I have successfully configured a 1310 Bridge as a Root Bridge and a BR350 Bridge and a Non Root Bridge/with Clients. I also had to force the 1310 to operate at 11MB only.
As soon as I make the BR350 Bridge a Non Root Bridge/without Clients, the authentication is dropped between the two.
I was hoping I could transition to the 1310 one unit at a time since I have over a dozen 350's to replace.

Wireless Root Bridge - Non Root Bridge

I've been reading a lot about bridge configuration for wireless AP but i cannot make it work the following scenario:
PC -- ethernet port --> Non-Root-Bridge -----------> Root Bridge ---------> Switch
vlan111                     native 18 - vlan111           native 18 - vlan111      vlan native 18,111
Its pinging fine between switch and Non-Root. But when i put vlan111 on Non-Root the two AP's stop responding to the network.
What am i doing wrong? Plz i need some help!! I have two 1242.
