Cisco :: HREAP Not Allocating Correct Ip Address WLC4402
Mar 20, 2011
I have two sites.Main site (local) has two Vlans: Vlan1 and Vlan2. Each has its own IP address range.VLAN 1 is the default Vlan and is used for CORPorate traffic. IP range 10.33.4.*VLAN 2 is for guest access to the internet IP range 10.10.10.*I have a WLC4402 on the this site with 2 WLANs: CORP on Vlan1 and GUEST on Vlan2.
Branch site (remote) which has 2 Vlans: Vlan1 and Vlan2. Each has its own IP address range.VLAN 1 is the default Vlan and is used for CORPorate traffic. IP range 10.125.15.*VLAN 2 is for guest access to the internet IP range 10.10.11.*I have an 1141 on this site using HREAP.
Locally, if you connect to CORP, you get a CORP ip address and access to CORP network. If you connect to GUEST, you get a guest ip address and guest access to the guest network. Simple so far....
Remotely, if you connect to CORP, you get a CORP ip address 10.125.15.x and access to CORP network (great). If you connect to GUEST, you get a CORP ip address 10.125.15.x and access to CORP network (not great). This is with the HREAP native vlan ID for the access point set to 2 on the controller.If I set the native vlan ID to 1 on the controller, I can not get an IP address at all.If I do not set the native vlan ID on the controller, I can not get an IP address at all.

Trying to implement HREAP over WAN between main and remote site. The WLC4402 is on main site. There will be a secondary DHCP at the remote site. Does the switch at the remote site any preparation?

I have a cisco 887 connected as temp measure to a 3g device via a fast0 port. all works fine. VPN comes up...but the moment i apply the crypto map to the vlan.. DHCP stops allocating ip address. I have remove irrelevant config ( dialer, atm etc as they not been used)
config below
p dhcp excluded-address 10.29.80.253 10.29.80.254
ip dhcp excluded-address 10.29.80.1 10.29.80.229
!

I am currently living in student halls, and so far I have been successfully using the halls' provided internet (ethernet port in wall) via a wireless router (belkin wireless ADSL). Until now.I have been unable to connect or the internet either via the router, or by direct connection to the wall.Whilst connected directly into the wall socket via the ethernet cable, my pc still thinks that I am connecting directly into the modem, and still labels the wired LAN connection as 'belkin 54g', despite the router not being connected at all.I have called the technical support for the network, and they have told me that my computer is assigning the wrong ipv4 address, and they had me do a cmd prompt and run ipconfig /reset and ipconfig /renew. This still did not solve the problem, as my PC still tried to connect with the same incorrect IP address. I know the problem is not with the ethernet port or cable, as I have tried in another room that has a working connection, and I still am unable to connect to the internet (DNS error on chrome).

I am trying to assign a static IP address for network adaptor as i am going to be using it to install Active Directory on VMWare Worksation. I was told that if i went into Device Manager within my worksation then Advance > Locall Administered Address and set a static IP, when i install AD and it asks to whether set a static or dynamic IP it would continue the install process. However, after setting a static ip it did not, can somebody tell me how i can set the correct IP address for me to continue instaling AD.

Just inserted a new 5508 WLC into the network. We current have 3 4404 WLCs, and there was a need to duplicate, as much as possible, the configurations on the 4404s, and the design. The 5508 came online as expected. We moved a few access points over to it. The APs got the correct address range. The clients are expected to get addresses in the same scope range as the APs. However, the clients are receiving addresses in the management IP scope.I know there are two "not a good way to do it" in here. Why is the management address range in the DHCP scope, and why are the clients using the same scope as the APs. We are going to change that. For now, the AP and client in the same range has been going on since we rolled out wireless in 2006.The 8 ports on the 5508 are configured for LAG. There is no dedicated port for management. They tell me not to do that on a 5508.

I'm planning to setup a network with more than 300 PCs. I know that using class C address is not enough to allocate number of IP addresses required. What I meant in the preceding sentence is that If I use this network address 192.168.1.0 (class C), it will allow only 256-2 = 254 IP addresses, What about other PCs in the network ?

I have an apartment with a shared internet connection with a roommate. I'm paying for all internet costs because he says he "doesn't use it as much as I do". He frequently slows my connection down by downloading movies and probably porn. Time to bottleneck this douche.
I have an ASUS WL-520GU All four slots are hardwired: my computer, his computer, PS3 in the main room, printer.Plus several mobile devices are connected via wireless throughout the day.I only want to bottleneck his computer.How do I do it?

We are currently running a ACE20 with 11 contexts. Recently we have seen that one of the contexts is being 'starved' of resources, especially Concurrent Connections, Bandwidth and Throughput.
Whilst we know how to address this situation by reallocating resources from less busy contexts, I was wondering if there was a more scientific way of looking at the resources being used and calculating the best way to allocate them across the ACE other than just looking at the 'show resource usage' and 'show resource allocated' commands?
Has Cisco or any other 3rd party developed a handy tool to monitor the the ACE resources which will possibly assist with calculating the optimum resource allocations across all contexts?

My customer requires the hostport on an access switch to be allocated to a specific Vlan based upon the AD Group that the user is a memeber of ? I am planning to setup NAC in a Real Gateway OOB deployment, using an ACS 5.2. I was initially thinking that the initial authentication server would be the ACS and then the AD, which using group mappings within the AD, I could then assign the user to a specific ACS group and then pass a Radius attribute back to the NAC manager for processing?

I have a T1 connection to one of my sites, I am running HREAP with 4 AP's. I have been noticing a spike in traffic from my AP's to the WLC. Even when no one is on the wireless. When you use encryption (DTLS) should this cause spikes on the T1 ?

I have a new deployment of 44 3502i AP's in 3 buildings at one of my campus'.The 5508 wlc is running latest 7.0.116.0 code.I have some users who take their work with them as they go from location to location on this campus.They need to be able to smoothly switch from AP to AP without having to reauthenticate each time the next AP takes over in the handoff.On the ssid in question we run 802.1x back to 1 auth server; there is no failover auth server.All APs are in one AP Group.My thought is to add all 44 of the APs to one HREAP Group.

I have a wireless network with two WLC 5508 controllers and 220 LWAPs in the same location as the controllers. All APs are currently in local mode. I run a few guest networks as well as some other client networks. One client in particular uses their network to connect mobile machines to their VLAN. The only issue is that the machines do not have wireless adapters. Instead, the manufacturer put inside the chassis, a D-Link WGB, which has an ethernet cable, you then have to plug into the ethernet port. These devices cannot seem to connect to the network. I have found, the WGBs do associate on the network, but the wired client behind it cannot pass traffic onto the VLAN. I have also tried connecting PCs with different SOHO style WGBs from different manufacturers with the same result.
After going through Cisco's documentation, I found that using 1230s in WGB mode can resolve this issue since they use IAPP to communicate the MAC table of the wired side clients they service back to the controller. I have configured a 1230, and used it as the WGB for the client machine instead of the D-Link and it does seem to work, but this would mean configuring a considerable number of 1230s to hand over to the client.
The first question would be, Is there something I am missing that I would need to do in order to allow SOHO style WGBs to forward wired side client traffic onto the network while LWAPs are in local mode? Or would the WGB NEED to support IAPP?
The second question is that, I may have found another solution to this already, but would like some input prior to committing.
This client also uses these same machines with the same WGBs inside the chassis at another location where the client operates the network themselves. They also use the same WLC model with the same version, and same APs. The only difference is that they use H-REAP mode with local switching.
I also tested this idea, and it seemed to work. With the AP in H-REAP mode, and the client's WLAN set to local switching, the machine and WGB connected with no problem.
So the question with this, would be; would there be any disadvantages in running all 220 APs at this location in H-REAP mode? What would I be losing if anything? Also, I would like to keep all other WLANs centrally switched.
I understand what the difference would be for this client's WLAN if I ran in H-REAP mode with local switching, but what would the difference be in the other guest WLANs if I set them to be centrally switched? (Is there any difference between running APs in local mode vs running APs in H-REAP with central switching?)

I have this Wireless deployment :
Main Site: WLC AIR-CT5508-50-K9
WCS 6.x for 50 APs
(32 ) AP 1140
02 Remote Sites : 03 AP 1140 using H-REAP
Now, my company is considering to implement a wIPS solution, so i planned to install in the Main Site a MSE3300 and (01) AP 3500e as a wIPS AP Monitor in the remote sites,
Need to confirm:
A) Can an AP3500 work with HREAP and as wIPS monitor AP at the same time? or in other words, if it is possible to have an AP wIPS monitor far away from the WLC (over the WAN)?
B) What are the requirements of WAN link if I want to install a Centralized MSE 330 Engine,which perform the wIPS solution in all the network.

How many AP in h-reap mode recommend with WAN link 512k ?,i have read in document it show h-reap mode must requirement minimum link is 128k for connect to wlc but i don't know this requirement for 1 ap or all ap to connect across WAN to register and send traffic across WAN. Because now i have 2 site HQ -> Branch (link 512k) it can use for this solution.

We have standart wireless deployment with 24 APs (1240G model) and wireless controller 4402-25 placed on same site.Most of clients (WMS RF terminals ) works with one WLAN (WPA2-PSK) and constantly roam over warehouse , and that works great.
But for better survivability(when controller dies) we are trying to configure HREAP on our APs with local swicthed local auth WLAN. And that also work , but client roaming occur much more slowly and RDP connection to WMS APP server sometimes stuck for 2-5 sec.Disabling "local switching" checkbox for WLAN make roaming almost momental.
And slow roaming are price for controllerless HREAP design ? And for fast roaming and survivability we must use N+1 wlc?

I have been having an issue with random AP3602I's in HREAP mode disassociating from the 5508 controller. These AP's are in remote offices with 70Mb WAN back to the controller. Randomly one or two AP's disassociate from the controller and I have to bounce the switchport to bring them back online. The WLC is running 7.2. Again this only occurs to one or two AP's not all of the AP's.

I have a tale of woe for you who may be considering Hybrid REAP with local switching.
My client has a varied configuration, but the requirements basically screamed HREAP with local switching. They have 15 sites, had already purchased a single WLC 4404 and they needed between 4 and 24 APs at each of the sites. Each of these locations are connected by a WAN link of good quality, but only a single link so there is no assurance of availability; the client has local resources so it would be useful if wireless stayed working during an outage.
So I setup the WLC for HREAP local switching. I setup AP Groups VLANs, but I noticed it had no effect on the VLAN allocation for HREAP. This was unfortunate, because not every site has the same VLAN configuration - some sites had a L3 switch and others only a L2 switch. But I suffered through this and configured each AP manually with the appropriate VLAN mappings.
The infuriating thing, is now that they have bought a second WLC 4404 (they expect to increase the number of APs beyond 100) all these VLAN mappings are messed up when APs connect to the second WLC. I've been going through them one by one again - it is really unfortunate that the AP Groups VLAN mappings don't apply to HREAP local switching.
I'm going to get back to the next 80 APs - but if some of you have a system for handling the VLAN mappings of a large number of APs.

I'm configuring AP in Hreap mode. Objective for me is th have a "plug & play" installation method for HREAP. I configure on HREAP AP, Native VLAN set to 1 and the WLAN and Vlan mapping for the current wlan is set to 1 too. WLC version is 7.0.230.0 and AP version is 12.4(23c)JA4
on my cisco switch (WS-C3560-24PS with 12.2(55)SE1), the port configuration is as below:
switchport trunk encapsulation dot1q
switchport trunk native vlan 45
switchport trunk allowed vlan 45,74
switchport mode trunk
no logging event link-status
no logging event power-inline-status
no snmp trap link-status
spanning-tree portfast trunk
spanning-tree bpduguard enable
AP receives a DHCP IP in Vlan 45 and users connected in vlan 45 too. I would like to undestand why the AP is working properly because normally vlan 1 is not configured as allowed vlan on my switch and the native vlan is dedicated only to untagged ethernet packet.

I have one cisco wlc 2112 with ios 7.0.230.0 with license to support 12 access points. My access points are nine (9) lap1231ag and one (1) lap1310.I just have one wlan (ssid). My scenario of deployment is in layer 3. I have one interface management and ap manager in the WLC. All my Access Points have differents ip address that WLC. I need to configure a unique ssid to associate my six (6) dynamics interfaces (each dymanic interface with different vlan subnet).Each wlan profile (ssid) should have the same security in phase 2 (wpa2/psk). My cisco access points don't support hreap. My wlc support only (4) interface into an interface group, and i need six (6) dynamics interfaces.

info regarding my LAP521 access points that are refusing to join the WLC4402-12.This is my first lightweight access point implementation and I have 3 LAP521's and 1 AIR-CAP3502I-E-K9 access points on my network.They are meant to pick up ip address from external dhcp server and then join the WLC but only the 3502i joins successfuly while the 521's get dhcp address but do not join the WLC. From the logs, I can see that the WLC is discovered by the 521's and even get a response message from the controller but they are still unable to join as shown in the screenshot below.My WLC is running software version 7.0.230.0 and the 521's are running an lwapp image version 4.2.61.8.

AIR-WLC4402-25-K9 running 5.2.193.0 and I setup guest internet-only access which worked for 2 days. I change both the "User Idle Timeout (seconds)" and "Enable Session Timeout " to 10hours (36000) as guest was complaining he had to re-authenticate again. Anyways, guest was still able to pickup ip address and logs show that life "appears" fine but he had not internet guest access. He had a Windows7 box...anyways, before I can finish troubleshooting, he had to leave....My question is if there is any issues with Windows 7 that others had a problem...or is it the timers I tweaked - or both?

We have 2 AIR-WLC4402-K9 devices at a remote location that will both drop their network connections some undetermined time after a reboot. We cannot reach them via telnet, SSH or HTTP. In fact, we cannot even ping them once they drop connection. The only cure we've found so far is to power-cycle the controllers. The controllers are in separate rooms and connected to separate switches. We've confirmed the links are configured as trunks and have the correct speed/duplex settings. I tried updating the IOS & boot loader on one of them but that had no effect on the problem.

I have a WLC 4402 on my network. Recently mobile phones can connect to the wireless network and obtain a valid IP address. This IP is pingable from a workstation anywhere else on the network. However, these phones will not display web pages. They come up page cannot be displayed. I even tried putting Google's IP address in the phone's browser and it still did not display. I can connect through the same WLAN via a laptop or iPad. These devices have no problem displaying web pages. I even went ahead and created a new TESTWLAN with no encyption but to no avail. Same results: laptops connect and display web pages and smart phones connect, gain IP but do not display web pages. Comes up page cannot be displayed. This matters not whether its an iPhone or Android platform.
