Cisco :: How To Know The CAPWAP Protocol
Sep 3, 2012I want to know the CAPWAP protocol.

View 1 RepliesWe setup some new CAPWAP AP 3602E in the network and configure the DHCP server option 43 , but the WLCs still cannot detect the APs , Do you know if there any new way to troubleshooting?
WLC: 5508 version: 7.2.103.0
SW:3750E
AP: AIR-CAP3602E-C-K9
I´m looking to a project where we want to start using Autonomous AP with possibility to change to controller based on near future.
Will Cisco Aironet 1040 Series Access Points allow us to change from IOS to CAPWAP when needed? I read some posts about the oposite process (CAPWAP to IOS) so I think it´s possible on both way. Can some one confirm this to me?
We have had several APs disassociating from our controllers. The alerts say, Message: Access Point 'AP-xxxxx' associated to controller '10.x.x.x' on port number '0'. Reason for association 'Dot11g Mode Change. I have read several posts that point out that you should have QoS implemented to prioritize the CAPWAP traffic. I'd like to know if someone has implemented QoS and whether it has been successful in stopping the APs from disassociating. And if it has been successful do you have any configuration examples for the ports attached to the AP and controller as well as the QoS configuration?
We have several sites with AP1142's and 3500's. We have 2 5508 controllers. We are broadcasting 2 SSIDs of which one is in HREAP mode and the other is in local mode. Each of our sites have MPLS circuits.
Here is an example I found on Cisco which I believe can be used for CAPWAP as long as you change the ports to 5246 & 5247 instead of 12222 & 12223.
Example Router Configurations #
This section contains router configuration examples to be used as guides when addressing CS6 remarking or LWAPP control traffic load.
#
This example uses LWAPP APs on the 192.168.101.0/24 subnet, and two WLCs with ap-managers at 192.168.60.11, and 192.168.62.11. (code)
I have an 1142 running capwap c1140-k9w8-tar.124-23c.JA4 that I am wanting to convert to an Autonomous AP.However, the AP does not seem to have an archive exec command to tftp downoad an new IOS.Is there another procedure that should be used ?
View 7 Replies View RelatedI'm looking at the spec sheet comparing Cisco WLCs and I see that the 2504 has a bandwidth max of 500mbps. Just to be clear, not all of the traffic from the APs goes through the WLC does it? In this setup, the APs would be plugged into a PoE switch as well as the WLC. The only traffic to WLC would be the CAPWAP tunnel, CleanAir info, etc right? All other traffic should just be handeld at the switch right?Also, does the 2504 licencing include CleanAir in the price?

The following image was downloaded: ap3g2-k9w7-tar.152-2.JA
The release notes say: Site-Survey Only Mode for 3600, 3500, and 1550 Access Points You can install Cisco IOS Release 15.2(2)JA on Cisco Aironet 3600 and 3500 Series access points and on 1550 series outdoor access points to perform site surveys. This release runs on these access points with limited functionality. You can manually adjust these settings on the site-survey access points:
• Channel on each radio
• Transmit power on each radio
• Enable and disable the radios
• Manually set basic and supported transmit rates
• Enable advertised cell power in beacons to client to enable DTPC for doing active surveys
• Enable and disable SSID broadcast in beacons
• Enable open authentication
My Question is: Where can i find a instruction for downgrading an AIR-CAP3602i to Autonomous 3600 AP? Is it complicate to get the AP running, or what do i need for "downgrading"?
I am trying to configure two AP-management interfaces to accept CAPWAP on different ports using the option "Enable Dynamic AP Management". One of them uses public ip address. However, I getting the message "Ignoring discovery request received on non-management interface ..." on this.
The controller is 5508.
I have a wireless network running with Controller WISM2 and I also have a NCS.I want to know if there is any way to look of individual log of CAPWAP and LAPWAP Access Points. It is better if I can see it through NCS.
View 1 Replies View RelatedI am facing this particular issue while providing Cisco unified Wireless solution to the customer. We are having CAPWAP 1252 APs controlled by WLC.
Scenario: 50 persons sitting in a hall with closely packed chairs using wireless simultaneously. Wireless access provided by patch antenna at a height of 11m from the user. As one AP can server 25 users, 2 APs are placed with antenna directions facing the compact users. Each users gets very good signal from these two APs.
Whether there will be serious interference and client association issues in this scenario? once one AP associates 25 clients, whether other 25 clients associate completely to other AP?
I understand that Cisco *wants* the APs to be directly connected to the new 3850.I have a few questions. Unfortunately, I think I know the answers. I just want to confirm.
a. When MA/MC is enabled on the 3850, does the 3850 start intercepting *all* CAPWAP packets it sees (much like CDP)? Even non-Cisco CAPWAP packets?
b. If I have a WLC 5500 upstream from the 3850, would APs hanging off a downstream 2960 be able to register to the 5500 through the 3850 when the 3850 is NOT in MA/MC mode?
c. If I have a WLC 5500 upstream from the 3850, would APs hanging off a downstream 2960 be able to register to the 5500 through the 3850 when the 3850 IS in MA/MC mode?
What I'm afraid of is:
a. yes, yes
b. yes
c. no
From the Q&A page:Q. Does the Cisco Catalyst 3850 support indirectly connected access points?A. No. The Cisco Catalyst 3850 switch will always terminate the CAPWAP tunnel locally. Pass-through mode or indirectly connected access point is not supported at this time.
I would like to confirm if it is possible to downgrade AP 1042 from CAPWAP to autonomous? I want to buy the AP model AIR-LAP1042N-A-K9. But i don't sure if in the future it could support this feature.

What could be causing it? I am using 1524 APs in a Mesh environment with a WLC 5508 (7.0.116.0) which is connected to a H3C switched network.
The MAC addresses above are from my MAPs and I don't think I am getting it from the RAPs.
Can I convert a standalone 1600 access point to a CAPWAP based AP when I choose to deploy a WLC later?Cant see any literature on cisco.com that is specific to the 1600 APs

View 1 Replies View RelatedI was working on a problem the other day and came across something that I had seen before but never given much thought. I had a router with a switch connected to it and the interface was showing as Ethernet0 is up, line protocol is down. The problem in the end turned out to be a cable that had fell out because it was not connected correctly, but I was able to replicate this interface status on a router (FastEthernet0/0 is up, line protocol is down), and NO cable was attached to the interface.I've had a look on the internet but cant seem to find a good answer, so does anybody else know why this status is shown on the router? Remember, NO cable is connected to the interface so it isn't a speed or duplex problem

I'm looking to make a possible configuration for a customer. They need a device to provide :- firewalling- bandwidth limiting based on protocols, IP, users- web content filtering- good reporting to see which device/users are consuming most of the bandwidth.I used to use cisco ASA as firewall but it's a while I last installed on and I'm nt uptodate which current state.So I thought of using an ASA 5512-X but I'd like to know if it comply with all the requirements .Most important being the reporting and bandwidth limiting capability. It would be great to have some configuration example regarding bandwidth management.

I am using the Self RADIUS server in my Cisco ACS SE 4.2 appliance S. I have an AAA client C that interacts with S by means of the RADIUS protocol. This works fine, in that S correctly carries out authentication chores on username/password (PAP and CHAP) pairs received from C, sending back to C the corresponding Access-Accept packet when the authentication succeeds, or Access-Reject when it doesn't.
I have been able to import a set of three VSAs into S. Each of those attributes is of string type. I then configured in S a single user U with password P so that, whenever a U/P pair received in S from C is authenticated by S, S should send back to C, in the Access-Accept packet, the three attributes with the following values: [code]
With this setup, when an authentication is successfully completed by S, C receives 53 bytes worth of data from S every time. I am attaching a typical example, already disassembled. I have disguised the actual vendor ID, for legal reasons, but the rest is exactly as it was when received in C.
According to the disassembly, what we got is an Access-Accept packet, as expected. Its length is 53 bytes - again as expected, for this is the only packet that C has received from S here. However, the packet is incomplete, for attribute #3 is missing its value field.
Looking into the whole packet in more detail, it can be seen that while the wire format for the first attribute, namely, Frame-IP-Address, is correctly constructed, the remaining are not. For example, the sequence of bytes corresponding to the attribute #1 reads 1a 09 00 00 xx xx 2c 61 62 63. I believe that this is incorrect; it should be 1a 0a 00 00 xx xx 2c 61 62 63, for the wire format for this attribute consists of 10, not 9, bytes. I tried a few variations on the values for the attributes, and the results are always substantially the same, in that the wire formats for these attributes are always incorrect.
This all probably implies I have done something wrong when importing the VSAs into S, and/or when configuring things on S. I am therefore attaching the csv files I used to import my VSAs into S; as before, names and vendor ID are disguised, but their lengths are exactly the same as in the undisguised file. I used two csv files: One to import the vendor ID, and the other to import the VSAs under that vendor ID. As for user U, in S's administration GUI I clicked on User Setup and selected user U, moved to the bottom of the screen, where the attributes for this particular vendor were present,introduced the values for each attribute mentioned above, and made sure that button in front of each attribute was ticked.

View 5 Replies View RelatedThe IP defined in RFC 791 was the first widely-used version of the Internet Protocol. Interestingly, however, it is not version 1 of IP but version 4! This would of course imply that there were earlier versions of the protocol at one point. Interestingly, however, there really weren't. As I mentioned above, IP was created when its functions were split out from an early version of TCP that combined both TCP and IP functions. TCP evolved through three earlier versions, and was split into TCP and IP for version 4. That version number was applied to both TCP and IP for consistency.url... what i wanna know s in tat underlined line its given 3 versions of TCP what r they?
