Cisco Wireless :: Configuring 1552E MAPs In MESH Topology With Controller?
Mar 21, 2013
I have to build a MESH topology with 1 Root Access Point and 4 Mesh Access Points which are 1552E.I have a wireless controller which is a WiSM 2 card into a 6500 chassis.I want to know if there is a pre-configuration to do on the AP before installing it, or if they are automaticaly discovered by controller (even for MESH AP which are NOT wired to LAN) ?
Done a wifi mesh using 1552E and 1552i mix of AP's ? With the 1552E as RAP and 1552I's as MAP's ? Is it a recommended model of deployment and will it work well ? the 1552i having radiation pattern more towards the ground when mounted on top , will the mesh backhaul to the 1552E be strong enough ?
Will this work if i put the 1552e at a lower level than the 1552i so that the mesh is formed properly ?
In our mesh network. there are 8 root AP and 15 mesh AP . we are using 1552E ,i have few questions on it:
1. If the ap's acting as mesh ap are connected with only 2.4 ghz external antenna, will they have problem joining the root access point to form mesh. 2. How should we set the channel assignments. Do we only set them in root ap's. 3. should the channels be set under 802.11a ? 4.should the channel be manually set or should it be left to be chosen dynamically.
recently I installed WLC 5508 en the central office and installed a network mesh in a remote office; central and remote office is connected with serial link as WAN, and I have dhcp server in the remote office for give ip address to all users and devices in the remote office. Additional I have 5 LAP1552 (mesh) and 2 LAP1260 in the remote office, all clients that connect to LAP1260(this don't belong to the mesh) receive ip address from dhcp server, but neither client that try to connect to the mesh (LAP1552) receive ip address from dhcp server. I don't have if I doing some thing bad. The range IP that receive the all ap's belong to the network of devices and the range ip for the users belong to network of users.
I have users that are unable to save their changes to topology maps - when devices are moved in a map and the map is exited, the next time the user goes into the map it is back at the default layout. The unusual part is that this does not affect all users - I have two users with the same CiscoWorks rights, but only one can save map changes. The admin user is one that can't save map changes. I'm running LMS 2.2 on Solaris 2.8. The problem existed before and after I upgraded to Campus Manager IDU 11, and stopping and starting services hasn't worked.
Release 6 controller 9 Mesh APs. 1524 (2x 5G radios, 1x 2.4G) and 1522 (1x 5G radios, 1x 2.4G) Designed for 3 linear hops and then a split to the rest.
AP1 = Root AP linear to AP2 Linear to AP3 Linear to AP4 equidistant to AP5 and AP6
The rest are further away from AP4, but have visibility back to AP 4 The issue is after an event (say a power outage) at AP4.AP5 uses AP3 as it's parent.That's okay during the power failure, but when AP4 comes back up, I want to force AP5 to switch it's parent to AP4.You may ask why, if AP5 can reach AP3 okay, it's okay to leave it that way.
So you can see it's desireable now that AP5 uses AP4 as it's parent.Over time, the system might figure it out, but our limited experience shows it seems to stick to the way it is.To complicate matters, sometimes we've found that it doesn't seem to reconfigure when the channel number has changed so AP5 can reach AP3, but AP4 (1524) comes up with a different channel on it's downlink radio.So, how can we force a mesh topology reevaluation/change for either 1 AP or the whole bridge group?I thought changing the bridge speed from "auto" to 54M (on AP3 above, for example) might force the attached children to rethink it, but it didn't seem to work (maybe I needed to wait an hour?).I also thought tweaks to "Radio Performance Profile" for radio might work. (not sure what to change, or how long to wait for a result)reseting APs and hoping they come back in a better topology is painful and slow.
Here's the current configuration in our organization (which I believe is incorrect):We have a number of Cisco 1500 series AP's (22 in total), that are mounted outdoors to provide seamless WiFi coverage over a large area. Each AP however has its own physical ethernet connection back to the WLC (All the AP's are marked as Root AP's). They are all broadcasting the same SSID. We have tried to stagger the channel selection but because there are only three non-overlapping channels to choose from, and in some areas the density of AP's is quite high, there is multiple places of channel interference. With this configuration we experience 100-150 disconnects from clients every day. (Our clients are mobile so they move throughout the coverage area constantly).
My idea is to switch the AP's to the same channel thereby forming a wireless mesh, use the built in functionality of the 1500 series to use 802.11a as the backhaul, designate one or two AP's as root AP's and wire them back to the WLC. Thereby forming a WiFi mesh, which if I'm not mistaken is the point of the 1500 series in the first place!
I am however completely new at WiFi networks and wondering if I am simply mistaken in what I believe my proposed changes will enable, or if there is a better way to tackle the WiFi topology.
I have one controller 5508 that will hold 50 LAP 1262 and another Controller that will hold another 50 outdoor mesh access point 1552. Both controllers (not redundant) are at the HQ while the access points are distributed between HQ and 3 branches.
The requirements is to have the SAME 4 SSIDs on MESH and LAP each have a security type (, wep,wpa,dot1x...) on HQ and Branches. Now, in the HQ I don't think I will face a problem since the WLCs is on the same LAN, so 5 interface v lans will be configured one for the WLCs and access point and another 4 interface v lans for the 4 SSIDs.
Now, for the remote sites I need to create another vlan on the switch with DHCP and option 43 ..... for the access point to register with the controller.
But here, do I have to create another 4 interface v lans (4 different sub nets) that should be bidden to the SSID as in the HQ?
Or the Access point will encapsulate all the traffic including the client traffic? Note that I have outdoor mesh access point and Lightweight access point and the BW link between the HQ and branch is 100M.
Also Can I have roaming between the same SSID that broadcasted on MESH and LAP knowing that each have different controller.
I am working on a project that will involve 5500 controllers managing 1260 series N rate A/Ps. There may be a requirement for MESH but my previous experience using Motorola 802.11a radios is that random, intermittent radio detections resulted in the MESH network having to keep re-forming resulting in less than 100% availability.
What's peoples experience in the UK is 802.11a outdoors?
Ideally i would prefer to use 2.4GHz and repeater access points for those areas not serviced with data connection but I cant find any info' so far on how whether the 5500 controller is able to manage repeater access points.
I have to install a wireless mesh network shortly using Cisco 1552 APs. This will be controller based using 5508 controllers. The controllers currently have some 1262 APs configured in a mesh and bridging configuration so happy that it all basically works. My question is - what is the "config mesh range' command doing on the controller ( or setting the Range(RootAP to MeshAP) setting on the controller mesh GUI. The default setting is 12000feet and I have left it at default at present. Just interested in what this is used for - I assume it alters the mesh protocol parameters somehow ( or the RF parameters perhaps ) as it suggests in the guide that mesh APs will reboot following this command being changed.
New to working with Wireless and the Cisco Meshing concept so have a few questions to ask.I currently have the majority of the mesh setup and configured. I have a setup with two RAPs with 9 MAPS connecting to each RAP.
First question is how many MAPS can connect to a RAP generally?Secondly how can I block other cisco AP's that are not in my mesh network from trying to connect to my AP's
The below is constantly hammering the logs for 6 devices that are Cisco close to my mesh that are not mine.
8 Sat Nov 12 23:31:53 2011 Mesh child node '58:35:d9:aa:db:4f' has changed its parent to mesh node '88:f0:77:b7:c6:e0' from mesh node '88:f0:77:b7:c6:c0'. Mesh Node '58:35:d9:aa:db:4f' failed to join controller, MAC address not in MAC filter list.
I have only added the MAC addresses of my AP's in to my AP Policy under security. Would these other AP's affect the mesh in any way?What I am seeing is the AP's constantly changing the child to parent relationship. I have inherited this network and they have about 20 AP's all within a square mile which is absolutely overkill. Would this close proximity of AP's together be the cause for the constant child parent changes?
How close should I have RAP's together. The network was setup so two raps are about 20 metres apart and the AP's on one side connect to RAP1 and the other to RAP2?How do you deal with Radar? The install is pretty much next to an airfield with radar running and a few times I have seen all the AP's disconnect and change channels.
We had our wireless mesh network running with 4400 Controller and 1510 A.Ps. Now that we have bought new 5508 Controller (with SW: 7.2) and 3600 Indoor APs, we are unable to add legacy APs on our new controller. After a wild googling I have found that for 1510 APs i need to be on SW ver: 4.0. But that will lead into another situation i-e I wont be able to have my 3600 APs on WLAN Controller.
I have Cisco 5508 Wlan Controller Software version 184.108.40.206 and I have Cisco AIR-CAP3602I-E-K9 Lightweight Access Points network and its working fine now I want to configure the Repeater in this network. Because there is one area we cannot layout the cable. How to add the repeater and how to configure the repeater in wlan controller network.
Do i need the change the software of Wlan Controller to support Mesh Network or this version 220.127.116.11 can support the repeater because for 1 access point i dont want to upgrade the version.
We have recently installed Cisco for our wireless solution. We are an education and are looking to let staff and pupils bring their own devices. The route that we are planning to take to let them join the school's WiFi is to implement a RADIUS server so that they can authenticate with their Active Directory username and password. I have tried to test the solution but so far without any success. I am using a Windows Server 2008 R2 as my NPS server, I have setup the Cisco controller as per below: Security Tab | RADIUS | Authentication - I added my windows server there and the preshared key, the Network User and Management is ticket and the server responds to a ping command,In the WLANs Tab, I selected my test WLAN and under Security | AAA Servers I selected the RADIUS server that I configured in the Security TabI then try to logon to my test WLAN and on the Cisco WLAN controller I get the following error: AAA Authentication Failure for UserName:test User Type: WLAN USER Before trying to tinker with policies on the Windows Server I was wondering if the RADIUS is correctly setup on the Controller or have I missed something obvious?
We have 4 1142N LAPs that I want to divide between an internal wireless and a guest wireless network using the controller. Currently all of the APs are on an established internal network, but I want to migrate one over to a test guest network before buying more LAPs to augment the networks further. Currently the port connecting to the WCS from the 3560 switch is configured as an access port using VLAN 10. Whenever I make it a trunk port carrying VLAN 10 as well as the other ports we will be using for the guest and ap-manager networks, I lose connection with the controller. To me this implies that the port on the controller is configured as an access port as well. In the documentation I found for the controller it states that by default the ports are al configured to be trunks, but it appears as though something was changed by the previous tech. All of the APs are connected to other switches, not to the controller itself.
1) How can I get the port on the controller back to being a trunk port
2) Can I use the internal DHCP server for the guest network if the subnet is different than the management subnet, or will I have to use another external server and relay/proxy it through the controller to give guest clients IP addresses?
I bought 6 air-lap1042n-a-k9 for our business. They are mounted. I bought a Cisco POE switch for them. I hooked them up and realized they needed a Wireless LAN Controller. I have never dealt with these before. From my research, I need to buy AIR-WLC2106-K9.Can I just connect my POE switch to the LAN Controller to configure all 6 access points that are connected to the POE switch?
1552E Rap will "lock" up, and not allow MAPs to connect through it to join. the WLC. Rebooting the Rap will resolve the issue, but the problem comes back and some random point in the future. Prior to rebooting the Rap to fix the issue, the Rap shows as joined to the WLC, but I have noticed that the neighbor details look stale, meaning my MAPs don't show up as neighbors, but other MAPs in the area are in the neighbor list, listed by MAC address. At this time, I can not confirm whether or not the neighbor detials are changing (updating), but I can confirm that my MAPs never show up as neighbors.As soon as the RAP is rebooted, MAPs join the controller again.
We purchased cisco AIR-CAP1552E-A-K9 and it has IOS c1520-k9w8-mx.124-23c.JA2. WLC with the lastest firmware 18.104.22.168 is not able to connect to the Cisco 1552E. 1552E log show that it can see the WLC but unable to connect. We have devices for both U.S and Australia domain. Why are the 1552E not able to connect to the WLC?
I've looked through the documentation for loading the autonomous image on a 1552E WAP that has the lightweight image on it. All the documentation I can find mentions using the "archive" command at the command line. It doesn't appear to like the archive command.
I've seen in the documentation that it also mentions the software is loadable through the controller, but I can't figure out how to do that.
I currently have the 1552E connected to my 5508 controllers running 7.3 software. how to load this autonomous image on to the 1552E? I'm planning on using it to do site surveys with the 1552E.
