Mesh with Ethernet Bridging

Hi all,
I'm running a 2106 with version 6.0.196.0. I'm running a couple indoor 1131s on it for regular client access successfully, but my problem is with trying to Ethernet Bridge Wireless Mesh two 1522s. I have placed the 1522 MAC addresses in the MAC Filter. I have Ethernet Bridging radio set on both the RAP and the MAP. I have the RAP and MAP connecting(They see each other as AWAPP neighbors, I can ping the MAP from the wired LAN, and it registers to the WLC, but I can't seem to bridge through these APs. I tried setting the Switchport attached to the RAP as an access port were the WLC and other APs sit as well as tried trunking it, making that same WLC vlan the native vlan. I also tried creating a separate AP group for the 1522s...no joy. Can anyone point me in the right direction on this?

Indoor WLAN and outdoor mesh is not supported on the same WLC at the same time.
So you cannot mix 1131s and 1522s on the same controller.

WLC 2125 with 2x 1520 Mesh Points - Ethernet Bridging

Hi - I'm looking for assistance with a new Mesh set up we are deploying, the solutions consists of:
1x Wireless LAN Controller 2125
2x 1520 AP/Mesh Points
What we are trying to achieve is to bridge two networks together, I have followed the Cisco configuration guide and I simply can't get the traffic to cross from one side to the other. The WLC can see both 1520's on either side of the mesh network and I appear to have set it up right.
Here is how everything is set up:
- Local network (Class B, 10.0.0.0/16) connected to Port 1 on the WLC.
- 1520 is connected to Port 2 on the WLC via g0/0 with an IP address of 10.0.3.110 (management network, 10.0.3.111 for the wlan-management network) - this is set up as the RootAP, with ethernet bridging enabled and the bridging group set to rsqmesh.
- 2nd 1520 is around 800ft away set up as a MeshAP with ethernet bridging enabled and the bridging group set to rsqmesh. Small 5-port switch (non-cisco) connect to g0/0 on this 1520 with a device attached which has the IP of 10.0.3.37.
All help is appreciated.
Thanks,
Craig.

Bridging will not work if the RAP is directly connected to the controller. But CSCsk15792 is filed on this issue. If you put a switch between the controller and RAP traffic should start flowing.

Outdoor Mesh AP Ethernet Bridging Problem

Hi All,
I've setup 6 X 1522 MESH APs.
Setup:
There is 1 RAP and the rest are MAPs. All APs have already successfully registered with the WLC (4402-50), with the RAP being the hub and all other MAPs a single hop away. APs are all in VLAN 10 (same vlan as the AP manager) and the WLC management interface is in VLAN 9. Bth VLANs are routable to each other. All APs are configured with Ethernet Bridging checked and all are configured with the same bridge group name. The switchports (Fa0/8) for each switch connected to each AP is configured to be trunk mode with native Vlan of 10. All switches are also configure with other VLANs such as VL20 - 30 besides the mentioned VL9 & 10.
Problem:We tried to bridge VLAN 20 across the wireless bridge by plugging a notebook(A) to a switchport (Fa0/1: sw mode access & sw ac vl 20) belonging to a switch connected to MAP1; and another notebook(B) also plugged in to a VL 20 access port whose switch is connected to the RAP. From notebook A, we were able to ping all relevant IP addresses (notebook B, WLC management IP, VL 20, VL30 ip addresses of equipment somewhere else in the network behind the RAP). This means the wireless bridge is already working as VL20 is already bridge across th MAP and RAP. However, when we tried to do anything else, such as ftp, IPERF, some other TCP dependent application, it doesn;t work. we setup a FTP server on notebook B and used notebook A to retrieve a file. ftp client in notebook A was able to perform login, list directory. But when a file is being pulled, it stopped after it downloaded exactly 1024byte of information. FTP will timeout after a while with only 1024byte transferred. However, using tftp, we were able to complete transferring the entire file. It seems that the wireless bridge or the switches which the hosts were connected to allows tftp (UDP) to go through but restricted big packets/blocks of TCP information to go through (since only file transfer or any other application involving larger data exchange fails, but logging in and telneting applications still works).
Very puzzled as we had previously configured wireless bridging before on the same model of APs and it was working.
Can any experts here offer any advise to our problem?
BTW, the WLC is on the latest version of the MESH firmware as of today. All APs gets their IP address dynamically from a router in VLAN 10 configured with the correct DHCP pool and option 43 parameters. DHCP should be working well as our APs are all registered with the correct range of IP addresses and all APs are pingable from anywhere in the network. LinkSNR between the RAP and the MAPs are very good ranging from 30-38 hence it should not be an issue of poor signal or interference or noise.
Thank you
Alvin

I've personally not configured the MESH gear to form a bridge, so I can't provide any "real world" expertise. Here is short document on how to set it up, so maybe something within it will catch your eye:

Setting up router with ethernet bridge

I have a new computer and want to re-setup my Linksys Model BEFSX41 Version 2 broadband firewall router with the Linksys Model WET11 wireless-b ethernet bridge to use my laptop wirelessly. I don't want the desktop pc to be wireless, just the laptop. Do I follow the steps in the FAQ "Hos do I setup my Cable modem with my Linksys Router?". Then are there more instructions for the ethernet bridge?
The pc is in the basement with the cable modem and Linksys router. The ethernet bridge is upstairs where the laptop is. Is this easy enough do to, or am I better off paying $75 to a computer tech to come to my house to do it?
Thank you for any suggestions.
Diane

You cannot do the job that you described with the equipment that you listed.
It is not clear from your note how you intend to use the WET11. A wireless bridge is designed to receive a wireless signal (from a wireless router) and send it to a computer that is wired to the WET11.
For example, the following setup would work:
modem -- wireless router )))      ((( Wet11 -- computer
but you never mentioned that you have a wireless router.
Note that your WET11 cannot broadcast a network, for example, the following DOES NOT work:
modem -- BEFSX41 -- WET11 )))      ((( wireless computer
However, instead of (incorrectly) trying to use the WET11 to broadcast a network, you could use a WAP (wireless access point) to broadcast your network.   For example, the following would work:
modem--BEFSX41--WAP )))   ((( wireless computer
                                  and/or   ((( WET11--wired computer
For a WAP, you could use a WAP54G or a WAP200.
Hope this helps.

Mesh Ethernet Bridging with VLAN Tagging Issue

Hi all.
I'm a little stuck with a 4400 7.0.220.0 + RAP 1550 + MAP 1260 Ethernet bridging issue. I'm using the VLAN tagging functionality and I'm finding that periodically a VLAN that I've tagged on the MAP will deregister from the backhaul and stop passing traffic. If I go into the Mesh tab on the MAP, select the wired interface, remove the VLAN from the list of tagged VLAN IDs and then add it right back to the list, its starts passing traffic again.
Has anyone else seen this? I can't find any relevant bugs.
Justin

Hi Saravanan,
It is one RAP and three MAPs. After a TAC call and 30 hours of monitoring, my VLANs have remained registered. I think the issue was mismatched VLANs to bridge groups an it looks like the mesh bridge may be stable for now. Here is what I was seeing on the RAP and MAPs when the VLANs were deregistering unexpectedly. Notice how VLANs 2 and 10 are mapped to opposite bridge groups on the RAP and MAP:
After I removed all the VLAN IDs from the Trunk configuration on the MAPs (through each AP's Mesh tab -- Ethernet Bridging config) and then rebuilt the VLAN IDs, I ran the same commands and now see this:
My very unscientific theory here is that the mismatching was causing consistency checks to fail, so the RAP was just tearing down the registrations after getting bogus or non- responses from the MAPs during the periodic VLAN registration maintenance checks (debug mesh ethernet registration).
If I have continued issues, I'll post back with updates.
Thanks for the response!
Justin

Dual RAP Mesh Network vs PTP Wireless Ethernet Bridging to provide link redundancy

Currently looking at a few options to optimize a current point-to-point wireless LAN-to-LAN connectivity shot for a wired customer site for better redundancy (hardware diversity and/or logical path diversity). Currently the customer is fed via an older solution, using two Cisco 1522 APs with Cisco Aironet 14-dBi Path Antennas (AIR-ANT5114P-N) for a 5-GHz PTP wireless ethernet bridge (under 3km), in which one 1552AP hangs off a L3/L2 Distro switch and the customer's 1522AP hangs off a 3750X switch, which has another access switch hanging off it via a fiber run of about 2km, which is exposed in parts and can't be re-run again due some limitations.The customer doesn't utilize any wireless services. Due to their location, we can't connect them to our wired distro infrastructure directly via fiber.
Looking at setting up two wireless shots (instead of just one currently used); 5-GHz point-to-point bridges using upgraded gear: Cisco 1552EU APs with Cisco Aironet 14-dBi Path Antennas (AIR-ANT5114P2M-N) or straight Exalt r5005 solution. The PTP shot will hang off two seperate distro switches for redundancy purposes, pointing toward the customer site at two seperate locations, spaced apart by approximately 1 to 1.5 km, so that they aren't at the mercy of being isolated on one side if they have another fiber cut which connects their two main access switches together. If need be, we can hang two main APs on one distro facing two APs at the customer site, since this would create some redundancy, just not the same level as above.
The below is what I'm really unsure on.
Possibly looking at setting up a mesh network using Cisco 1552E APs with 2.4 GHz Omni-directional antennas (either a 2.4/5GHz Terrawave MIMO Omnidirectional antenna or Cisco AIR-ANT2547V-N antennas, which ever is best) with two RAPs, one RAP hanging off one distro and the other RAP hanging off another distro for hardware diversity, both under the same bridge group name and both RAPs hanging off the same WLAN management SVI subnet on the distros. The customer site will have two 1552E MAPs located at two seperate sites, as pointed out above. I don't think a third AP would be needed, since they don't use wireless services. Since there would be only two RAPs, not three, would it be best two set-up this with both RAPs on the same channel to minimize convergence time should the mesh transfer from one RAP to the other RAP, as long as both RAPs are spaced apart under ???? distance to avoid interference/other issues? Looking at some documenation, it appears you can have a MESH network, as long as your MAPs and RAPs fall within a 2 mile range area, preferably closer to a 1 mile range area (for better bandwidth & reliability). This solution has been brought up as possible dual-homed solution in theory, by virtue of having two more more MESH APs fall within the range listed above, to the RAPs. From a layer 3 perspective, I'm not sure what the most optimal idea to run with in this scenario set-up would be. Possibly set-up two seperate user SVI VLANs (for their data services), one placed on each access switches these MAPs will hang off at the customer site, & using the same management SVI subnets as the RAPs for the wireless managment side (for accessing the APs). From my understanding, the user data SVI doesn't matter from the perspective of when the mesh transfers from one RAP to another, it should be transparent to them. The distro switches will just have the management SVIs placed on them for the RAPs, the user SVIs will be placed local on the access switches only. And all APs will hang off access ports set to the management VLAN ID.
In my opinion, the PTP 5-GHz, dual distro homed solution makes the most since for wired client access, but since the latter option was brought up, it has to be weighed - plus I'm curious if it can work.

The Exalt r5005 works great for redundancy PTP links. You have to use the sync cable between the two co-located bridges and also set the polarization on the bridges. You can then use routing or spanning tree to decide traffic path. With mesh, you will have to make sure you set the parent or else the maps will keep switching perhaps.

WRT610N v2- Which Ethernet Bridge to buy to go with it for LG BD370 BluRay player?

I have a WRT610N v2 router, which I LOVE. I need an ethernet bridge (to connect a LG BD370) Blu-Ray DVD player. I've spoken with Linksys tech support & I'm sad to say, got misinformed. I'd actually ordered a PLS300 (which I cancelled) when I found out there weren't any updates for it. I'm running Windows 7 Home Premium 64 bit.
The tech support person first told me I needed a WET610N & then changed her mind.
The WRT610N is located in the office about 15 yards from where I need to connect the ethernet support to the entertainment system. I also have a wireless printer (Lexmark Platinum PRO905 that is about 5 feet from the LG Blu ray player. Is the ethernet bridge going to interfere with the Blu ray player?
I'm just wanting to get connected to NetFlix. I've paid for this service since last spring but am just now getting around to sorting this out.
Any help would be greatly appreciated! TIA

Thanks, Gollum! I've now got the WET610N ordered & the EZXS55W ethernet switch. They both should be here by Friday.
The WRT610N router is in my office, hardwired to the HughesNet modem & HP Desktop running Windows XP Pro. The two new laptops (HP dv7-3078nr and HP dv8t-1000 (both running Windows 7 Home Premium 64 bit)) and the Lexmark Platinum Pro905 AIO are in my den (about 30 feet away). Right now, the dv8 (my main laptop I keep on continuosly & the Lexmark Pro905 are both here in the den, connected wirelessly to the WRT610N.
Here is the configuration of the entertainment system:
LG 50PS60 Plasma HDTV
LG LHT854 Surround Sound
LG ACC97WK-R Wireless Rear Speaker
LG BD370 BluRay DVD Player
I have DISH network with a 722K DVR
Do I need to connect the WET610N first? Then add the bridge? This is where I am afraid I am going to mess up.
Right now, everything is working GREAT.
Do you think I need to hardwire the Lexmark printer into the switch?
Could someone please advise (in very simple steps) what I need to do to get the WET610N & ethernet bridge connected?
All I want to do is be able to download NetFlix movies! I am scared that the (((HughesNet))) is going to be the problem due to their low FAP cap. Due to my location (I am 25 miles from the closest town with wireless (Verizon, Sprint, etc) offices & have already tried 3 different wireless cards here (none of which worked due to our location).
I'm beginning to think it would have been simpler to just buy the LG BD390 (wifi already installed) & put my BD370 on eBay! LOL
Any help would be greatly appreciated! TIA

Can't use my TC as bridge with ethernet

Hi all --
Here's my set-up : I use my ISP box as wifi router. I added my Time Capsule wirelessly to the existing network.
Wireless network works fine : I can access Internet and the TC drive.
Here's the problem : I'd like to connect a PC via ethernet to the TC in order to access the web (the PC doesn't have wifi). I get no connexion...
I tried to connect my Macbook to the TC with ethernet and got the same result.
Here are some bits of info : the TC gets its ip address (192.168.1.21) via dhcp from my adsl box, BUT both the PC and the mac get a different IP address (i.e. 194.169.x.x) when connected to the TC via ethernet. Could it be that the TC is assigning ip addresses even though it's designated to act as a bridge ?
I am at loss. Thanks for any help.

on the summary screen, I have "wireless mode : join a wireless network" (may not be the exact wording since I'm on a foreign system), and the IP Adress is 192.168.1.21.
Again, the TC is NOT connected to the ISP box via ethernet but Wifi.
On the Internet tab, I have :
- connect via : wireless network
- configure IPv4 : via DHCP
- IP Address : 192.168.1.21
- subnet : 255.255.255.0
- router : 192.168.1.1
- DNS server : 192.168.1.1
- Connexion sharing : off - bridge mode.
Hope it helps...

Issue with cisco ONS 15310. Slot with Ethernet ports, designed for bridging.

Hi, guys. I’ve got an issue with cisco ONS 15310 sdh optical network. I’ve got a special slot with Ethernet ports, designed for bridging. Assume, we’ve got to multiplexers, named A and B with ports A0 and B0 respectively. The ios console of these slots says, the configuration is as follows:
no ip address set on these ports
Ports are administratively up
Auto mdix
Bridge groups are the same on these ports.
Dot1q tunnel.
I’m trying to monitor a device with an ip-address connected to port B0. It answers ping if I connect the notebook directly to a device. But if I connect the notebook to port A0 and ping the device pluged in port B0 through the optical network, it doesn’t answer. I tried connections with straight and cross cable.
Guys, who set the network said, it should work as a point to point bridge with no extra configuration. But it doesn’t. I used wireshark sniffer to lookup what’s happening on port A0. All I see is cdp-s from port A0 and self-announcements of the notebook.
Any suggestions? Thank you in advance.

What device will you use to set up the AirPort Extreme? Mac? iPad/iPhone?
If you have a Mac, we need the operating system that you are using on the computer. If you are not sure, click the Apple icon in the upper left corner of the screen, then click About This Mac. Post back with the OS X Version number that you see there.

WLC ethernet bridge

Hi,
I've a WLC 2106 and it is running IOS version 7.0.240. I am trying to setup a wireless mesh and used the ethernet bridge port on the MAP to extend the network. The wireless mesh works fine but I can not get the switch to work that is connected to the ethernet port on the MAP.
I'm using two different Access points. I'm using a Air Cap 3502i as the RAP and a Air Lap1142N as the MAP.
The switch port that is connected to the RAP and MAP is configured as the following:
switchport mode trunk
switchport trunk native vlan 2
switchport trunk allowed vlan 10,20,30,40
The RAP etherbridge port is enable and set to: normal
The MAP etherbridge port is enable and set to: Trunk,
native vlan is set to: 2
Vlan id 10
Vlan id 20
The wireless mesh between the RAP and MAP works fine. I can connect a device to the MAP wirelessly and access the network with no problem but I can not get anything to work that connects to the switch that is connected to the MAP ethernet port.
Could someone please tell me what I'm doing wrong?
　

I would open a TAC case as this is a bug. I don't recall what code it stopped working but I know it doesn't work also in the v7.3 & v7.4

Ethernet Bridging - Client DHCP issue

Good Afternoon,
We are having a strange issue taht i am sure others have run into before.
Currently we have a WLC 5508 with 2 1552 Outdoor Mesh APs running code 7.4.100.0.
We one configured as RAP and one as MAP. This is essentially setup just as a backhaul (trunk link). We ahve the RAP setup as Normal and the MAP setup for Trunk. We have configured to pass all VLANs we need (pruning). The mesh link works as expected the only issue is when we try to connect a client to a access port (VLAN 18) on a switch the MAP side (ethernet bridged). We are unable to get a IP address assigned.
However. We can statically configure an address in that network and Unicast traffic works just fine. It appears the broadcast traffic is not making it across the Mesh link.
Thoughts?

With mesh, you do not need to enable ethernet bridging at all. All the traffic should tunnel back to the WLC as if the mesh ap was a local mode ap. Make sure that if you are using AP Groups that the WLAN to vlan mappings are correct. The other thing is that you should be on v7.4.121.0 and also make sure you have uploaded the latest FUS 1.9.0.0 onto the WLC for stability. I have mesh networks on both v7.4.121.0 and v7.6.120.0, working just fine.

Can you use a 3600 for an Ethernet bridge??

Can you use a Cisco 3600 to do a P2P bridge? Using the MAP's ethernet port to connect to a remote LAN? On that remote LAN can you have lightweight APs that connect to a controller on the RAP side?

Can you use a 3600 for an Ethernet bridge??
http://www.cisco.com/en/US/docs/wireless/controller/7.0MR1/configuration/guide/cg_mesh.pdf
Check - Converting Indoor Access Points to Mesh Access Points
Ethernet bridging has to be enabled for the following two scenarios:
1. When you want to use the mesh nodes as bridges.
2. When you want to connect Ethernet devices such as a video camera on the MAP using its Ethernet port.
Wireless Backhaul:
In a Cisco wireless backhaul network, traffic can be bridged between MAPs and RAPs. This traffic can
be from wired devices that are being bridged by the wireless mesh or CAPWAP traffic from the mesh
access points.
Guidelines For Using Voice on the Mesh Network
• Voice is supported only on indoor mesh networks in release 5.2, 6.0, 7.0, and 7.0.116.0. For
outdoors, voice is supported on a best-effort basis on a mesh infrastructure.
other factors to note:-
#you would be running on backhaul using A radio which is prone to DFS.
#CAPWAP may not tolerent enough with AWPP convergence on MAP roaming.
#CAPWAP is more latency sensitive than voice.

How can I use my time capsule with Ethernet cable? How is it also possible to use time capsule as a normal external hard drive?

My problem is that I don't know how to use my Time Capsule with Ethernet Cable, as when I use wireless it is really slow.

Make sure that there is an Ethernet cable from one of the LAN <-> ports on your modem/wireless router to the WAN port on the Time Capsule
Click on the Wireless tab at the top of the page
Change the setting for Wireless Mode to Off (I assume that you do not want the Time Capsule to provide a wireless network since you already have a wireless network)
Next, click the Internet icon at the top of the screen, then click the Internet Connection tab
Connect Using = Ethernet
Connection Sharing = Off (Bridge Mode)
Click the Update button at the bottom and wait 30 seconds for the Time Capsule to restart and display a green light
Then, you must power off your entire network...all devices....in any order that you want
Wait a minute
Start your modem/router first and let it run a minute
Start the Time Capsule and let it run a minute
Keep starting devices one at a time until everything is powered up
If you are using Time Machine for backups, you will need to reset the connection because you have changed the way in which the Time Capsule connects to your network
Open System Preferences (gear icon) on the dock
Open Time Machine
Click Select Disk
Click the Time Capsule to highlight it
Click Use for Backup or, it might be Use Disk
Now you can connect your Mac using an Ethernet cable to one of the LAN <-> ports on the Time Capsule to back up using Ethernet. Be sure to turn off the wireless on your Mac before you start the backup.
If you want to backup using wireless, disconnect the Ethernet cable from the Mac to the Time Capsule and turn on the wireless and connect to your wireless network. Your computer will now backup using wireless.

How can I create a new TC backup with ethernet, so I don't have to wait two days for a new wireless backup?

How can I create a new TC backup with ethernet, so I don't have to wait two days for a new wireless backup?
Several times in the last year, I've gotten a message that Time Machine needs to completely redo my backup. Using the wireless connection, this takes almost two days. Is there a way to do the backup with ethernet and then switch back to wireless? Thanks.

May I know what is needed to make sure the MacBook is able to see Time Capsule on ethernet?
Connect an Ethernet cable from one of the LAN <-> ports on the 2Wire gateway to the WAN port (circle of dots icon) on the Time Capsule.
If AirPort Utility cannot "see" the Time Capsule now, you will need to perform a "hard reset" by holding in the reset button for 7-8 seconds or so and then reconfigure the Time Capsule. You can use the same Time Capsule name and password, etc. as before.
Configure the Time Capsule to "Create a wireless network" and select the Bridge Mode option when it appears during the setup using AirPort Utility.
Once the Time Capsule is configured, restart the entire network again. Power down everything, start the 2Wire first and then start each other device after that one at a time about a minute apart.
Now you can connect your Mac directly to one of the LAN <-> ports on the Time Capsule for the backup using another Ethernet cable. In general, about 20-25 GB per hour will transfer.
The Time Capsule will broadcast a much faster wireless network than the 2Wire can provide, so you might want to leave the setup "as is" for awhile after the first backup is complete. If you decide to use the Time Capsule as your main wireless access point, you would want to turn the wireless off on the 2Wire since two wireless networks in close proximity can create interference problems.
Or, if you want to use the wireless on the 2Wire, you could turn off the wireless on the Time Capsule. Then backups will occur over the 2Wire wireless, or over Ethernet.
I don't really recommend the "Join a wireless network" setting on the Time Capsule for most users, but you could go back to that setup as well if you want after the first backup is complete.
