1250 series in bridge mode
will I be able to achieve throughput of around 100 Mbps in point to point bridge mode as 1250 series supports n draft ?
Here is the Cisco's answer for the question. What type of top speeds can you realistically get with 11n in the real world?
The answer is "it depends". The actual connection rate (at the physical layer) is dictated by the quality of the client's connection. This can be anywhere all the way up to 300 Mbps. Then, from that actual connection, your 'real' throughput is a bit lower. In a real world environment, the peak sustained throughput (per radio band) can be up to and well past the 100 Mbps mark. As with any wireless technology, mileage may vary based on myriad environmental and system variables. Look to 11n to provide a very significant throughput increase to existing 11a/b/g networks.

1250 802.11N series in root/non-root bridge mode
Using Yagi's, low loss cable, antenna outside, AP inside.
When operating autonomous 1250 series in root/non-root bridge mode, can I use 802.11N radios? Is it supported?
Or would it be better to use 1242's? This is for a customer, no time for testing, need rock solid design, in and out configuration...@leolaohoo -
I was just asking for a definitive answer, weather its affirmative or negative, is there a benefit to using the 1252 over the 1242 giving the cost of each, since as you said the 802.11N can not be used to bridge, than I would say a 1242 is better fit for the AP bridge of 350', clear line of site over the 1252. -
N bridge between two 1252an in bridge mode at 5GHz
I've read in some of the cisco documentation on the 1250 series that root bridge or non root bridge modes are "not tested". They don't say "not supported". I have a client that could use a high bandwidth link between two buildings that are 100' or so apart. The fiber link has already been busted twice. Heavy heavy trucks kill the ground concrete. I have configed a 54Mbps solution with two 1242G's and some cisco yagi's. But, if an N bridge is possible with two 1252AG's, and go faster than the 54Mbps..I'd go with that setup.
Cisco documentation says the bridge modes show up in the 1252 webgui and are selectable. They just end it with "not tested".
Any thoughts?It became supported in recent versions of the 1250 IOS.
|With this feature, the Cisco Aironet 1140 and 1250 Series can be configured for both access point and bridge functions. Bridging support on 802.11n access points offers added performance, reliability and throughput for basic wireless LAN coverage, wireless LAN coverage with wireless backhaul, and more traditional bridging applications.|

MQ Series, Messaging Bridge, weblogic 7.0
Hi all,
I have seen other postings about this with some clues as to why I am having this
problem, but I still can't seem to resolve. I have already tried to gleen some
clues from the documentation that comes with the beta bridge to be used with 6.1
(wls_mqseries.pdf). Has anyone configure Weblogic 7.0 successfully with the new
Messaging Bridge? If so, could you summarize your steps and settings?
I used the JMSAdmin tool to bind the factory and queue objects and setup the destinations
on the WLS console, but the log keeps spitting out the following:

Thanks for your help,

Tom,
Thanks. The white paper seemed to have the info I needed.
Now I just need to figure out why the lookup of the MQ objects return javax.naming.Reference
rather than the actual object. I do have the ibm jar files in the classpath.
Thanks,
Mike

How to configure router in bridge mode
Hi
I have 2 cisco 2621 series routers to be configured in bridge mode.
i'll be connecting this 2 routers using serial connection 128 lease line.
the problem is im not sure how to configure this 2 routers in bridge mode.
as far as i know, i need to issue the command no ip routing.
is there anything else i need to do?
can anyone guide me on how to configure
the router in bridge mode? is there any support page for this is cisco website?
thanks
JegaPlease check the link to the configuration guide below. It describes how to configure transparent bridging.

1300 series as Bridge and AP both
Any idea if 1300 series is bridging with another 1300 with integrated antennas on both the end, how would be the performance of it if used for AP mode as well as it works both ways.
Configuring access points and bridges to treat a workgroup bridge as a client device allows more workgroup bridges to associate to the same access point, or to associate using an SSID that is not an infrastructure SSID. The performance cost of reliable multicast deliveryduplication of each multicast packet sent to each workgroup bridge limits the number of infrastructure devices, including workgroup bridges, that can associate to an access point or bridge. To increase beyond 20 the number of workgroup bridges that can associate to the access point, the access point must reduce the delivery reliability of multicast packets to workgroup bridges. With reduced reliability, the access point cannot confirm whether multicast packets reach the intended workgroup bridge, so workgroup bridges at the edge of the access point's coverage area might lose IP connectivity.
When you treat workgroup bridges as client devices, you increase performance but reduce reliability. You use the no infrastructure client configuration interface command to configure access points and bridges to treat workgroup bridges as simple client devices. This is the default setting. -
Bridge mode - MAP /RAP - Client service
Hi all.
I'm very confused about the MAP and RAP mode as they are APs configured in Bridge mode.
In the CCNA Wireless, we are clearly taught that Bridge mode APs do NOT deliver client service...
Apparently Mesh and Root APs are APs in bridge mode but do deliver client service!!!
I've surelly missed something. Could someone help please?
Thanks
AlexHi Alex,
Bridge Mode AP
Many Wi-Fi bridging mode products exist with varying levels of functionality. Some wireless bridges support only a single point-to-point connection to another AP. Others support point-to-multipoint connections to several other APs.
Each AP in bridging mode connects to a wired LAN. Some AP models simultaneously support wireless clients while operating in bridging mode, but others work as "bridge-only" and disallow any clients from connecting.
Root AP - Places the bridge in the access point mode. In this mode, the bridge emulates a Cisco Aironet Access Point(example: 1100 Series ) and accepts associations from client devices.
Hope it helps

Request for "Bridge mode" after firmware update
Since updating the firmware on my Extreme the amber light continues to flash, although I appear to have normal internet connection. When I check with the Airport set-up utility I am told that there is a problem and I should select "bridge mode". Can anyone talk me through how to do this?
Given that your AEBS is in series with another router (your Linksys), you should use Airport Utility -> Internet panel to set Connection sharing: Off (Bridge mode). This will accomplish two things:
1) The annoying yellow LED will turn green.
2) Any clients wired into the AEBS LAN ports as well as all your wireless clients will now be on the same private LAN segment as all the clients plugged in to the Linsksy. As Martha would say, its a good thing.
You will, of course, still have Internet access but you will gain easy access to othe machines on the wired network for file sharing, Bonjour printers. You can check that this has occurred by displaying your IP address now (Network Preferences -> Airport -> TCP/IP panel vs what you see after you turn on Bridge Mode and reestablish the wireless connection. The IP address numbers will change. -
ASA supports NAT in bridge mode??
any one know if an ASA supports NAT in bridge mode? especially the 5580 series x??
Hi Hans,
Yes it does, from version 8.0 and higher.
Unsupported Features
These features are not supported in transparent mode:
NAT /PAT
NAT is performed on the upstream router.
Note: Starting with ASA/PIX 8.0(2), NAT/PAT is supported in the transparent firewall.

1200 series as bridges under LWAPP
If I want to user 1200's as point-to-point bridges, can I run them under LWAPP or do they have to remain Autonomus?
Workgroup bridge mode is not supported with 1242 or 1130 series APsin LWAPP.

My Airport Extreme is working with an Airport Express to wirelessly extend my wireless network. Both Airports are configured in Bridge Mode per the instructions I found on Apple's support site. I want to assign a specific DHCP address to a wireless camera that is in range of the Extreme, but I understand that the Extreme needs to be in DHCP Only mode to do this. But if I change the mode to DHCP Only, the Extreme will lose contact with the Express. How can I get both functions to work - wireless network extension and specific DHCP addresses?
Then what device is providing DHCP? Only once device per subnet should be the DHCP server. One should be DHCP and NAT and the other in Bridge mode for most home setups. The unit with DHCP and NAT should be the one connected to your cable or DSL and the other set in Bridge mode only extends your network.
On the wireless config page set whichever you're using to extend your network to "Extend a wireless network" and give it the details of the network to which you're attaching it. -
How do I clean up my new FIOS connection? I just cahnged ISP Fios and they reqquired a router of thier own in front of my AirPort Extreme. Since then I have blinking yellow light on the AirPort and AirPort utility keeps promting for an edit. Suggests canging from NAT to "Bridge mode". Obviuosly U have some internet or this post would not go anywhere, my knowledge base is not enought to feel comfortable with changing the settings. Correctly editing can be tricky, so how do I make necessary changes?
How do I clean up my new FIOS connection?
The FIOS router needs to be in Bridge Mode to prevent the Double NAT error from occurring when two routers are both fighting with each other for control of the network.
Unfortunately, the likely problem from the FIOS side is that FIOS support will either tell you that their router cannot be configured to operate in Bridge Mode, or if it can, they will not tell you how to do it.
But, it could not hurt to check with FIOS to see if anything might have changed recently in this regard, so your first call would be to FIOS support.
If you cannot change the FIOS router to Bridge Mode, the alternate plan would be to change the AirPort Extreme to Bridge Mode. If you are using the Guest Network feature on the AirPort Extreme at this time, that feature will not work correctly when the AirPort is set up in Bridge Mode. -
New Airport Extreme in Bridge mode -- some devices have no internet access
I just bought a new Airport Extreme as my old one which was probably 7 years old required restarting every day. My setup is as follows: DSL cable modem to Linksys Router (for a long set of convoluted reasons, I can't remove this layer) and then Airport Extreme. This is how I had it set up with my old one. The only difference is I recently started looking into using "Back to the Mac" on MobileMe and in order for it to work, I set my new Airport Extreme to Bridge mode due to dual NAT. I have an iMac, PC, MBP, MBA, iphone 4, AppleTV and ipad. All was working fine last night when I set it up. 24 hours later, for some odd reasons, I can't have my PC accessing the wireless network at the same time. If I did, it would knock my iMac off the network and says some other device is using the same IP address. For a while, only my iMac (my main computer) can access it and even my iphone can't. At this very moment, my iphone, imac and MBP all have access to the wireless network. My MBA and iPad has no internet connection. I've restarted Airport Extreme, Linksys, and modem more than once... If I switch back to "Use Public IP Address" instead of Bridge mode, everything works except for "Back to the Mac"... Help!
Hey Bob, Thanks...I have already repeated that multiple times yesterday and today but to no avail. I tried to get into the Linksys router control panel but unfortunately we can't remember the username and password (the router is not mine). The make things even more complicated, the router is actually part of the internet package provided by the ISP and they use a PPPoE to log in. Theoretically, we could do a hard reset but the problem is the ISP will not release the PPPoE information unless we sign a long and complicated form saying we want to bypass their Linksys router. We can do that but this process will take days and weeks... Our ISP confirmed that the Linksys router is set to max out at 5 DHCP but we can only connect 3 machines at a time. They are coming out to take a look tomorrow but in the meantime I have reset the Airport Extreme to "Distribute a Public IP Address" mode which will allow access to all computers/devices. What's even more weird is that if I did the Bridge mode, it messes up the Linksys router's own network as well. We can't even just sign into that network... Any ideas why?

Access to Time Capsule in Bridge Mode from outside of the network
I have a Time Capsule with an external hard drive set up in bridge mode on my home network. The main router and DHCP server is an Actiontec MI424, and is specific to my ISP (Verizon, required for TV Guide info from Fios) so the Time Capsule's AirPort can't be used as the primary. I need to access the external hard drive from outside my network (I.E. the internet), but I'm having trouble figuring out which ports are required for Sharepoint to work.
So far I've forwarded 548, but I get an error "-36" when I try to connect from the outside. It works fine on the inside. Any suggestions?
Thanks, JSDThe Express units can extend wireless on the TC or each other.. but they cannot extend wireless on the Asus anyway..
So the setup is Asus--TC (that has to be ethernet) The TC in bridge mode.
Then TC -- express can be done by ethernet in roaming mode as bob listed above or extend wireless.
I am guessing.. what model are the express units.. they are older Gen1 N model ??
IMHO the TC is simply no longer viable.. replace it with one express as the AP and extend it with the other Express.. see if that works better.
But I would be trying to use the wireless just from the AC66U.
I would also force the Asus back to 20mhz on the 2.4ghz band.. so you can provide adequate channel separation.. 40mhz wireless on 2.4ghz works poorly anyway because you have too much wifi .. there is very limited number of non-overlapping channels.. ie 3. 11, 6 and 1. -
I reset my airport extreme router the other day because I was too lazy to reset the password on my private network.
I have been reading the advice found on apple support communities and wide web, but the solutions do not solve any problems and often create new ones.
I'm regretting because everything was working just fine.
But I remember having this double nat error when I first set it up a few months back, but now I cannot resolve it.
I would live with the yellow light, but it seems that this double nat error is preventing my playstation 3 from connecting to the airport extreme.
When I put the aiport extreme into bridge mode, I loose all my wireless networks, even when I reboot the airport extreme and the modem.
I try rebooting the modem, then the airport. and vice versa. No internet.
I switch back to NAT/DCHP and the internet works fine on apple devices, but not the playstation 3, and I have the 1 Double NAT error.
I have a plain stock Motorolla modem and I can dial in and see settings (although nothing about NAT). I didn't see where to see them.
I tried setting the DHCP only but it said it didn't like the settings. is there a stock range i could be using?I have a plain stock Motorolla modem and I can dial in and see settings (although nothing about NAT). I didn't see where to see them.
Exact model .. motorola make adsl, cable and probably wireless modems.. with some modems and some modem router.. we need exact info. What kind of broadband do you have?
I would note.. some of the motorola cable modems seem to have issues with the apple routers. If you are about due to change modems.. now is a good time.. not another motorola.
If the modem is a straight cable modem, the AE must be in router mode.. but you need to power down the cable modem. maybe for 20min so the new router can pick up the IP address.
You cannot use DHCP alone.. the ISP do not give you a block of IP addresses.
You cannot use bridge with a pure modem.. you will find it works.. but only to one device.
The only reason you get double NAT is the failure to pick up the public IP.
Give the info required..
If you have trouble, I need the actual IP of the modem. the actual IP of the AE WAN port when plugged in. Screenshots are good.
