Cisco :: 5508 Virtual Machines With Bridged Connection / No IP From DHCP?
May 31, 2011We are experimenting with virtual machines running on some laptops here as part of a future deployment.Equipment in use:
-5508 WLC
-1262 LWAP
The actual operating system has no issues connecting to the wireless. When you start the virtual machine on any client machine (OSX, Win 7, Win XP, anything) it is unable to get an IP through an external DHCP server when the VM is set up to use a bridged connection.This works fine with Autonomous access points and over cable all mapped to the same VLAN. Helper addresses are configured on the VLAN.Is this a limitation of the WLC where it cannot provide more than one IP address per MAC? Is it a limitation of CAPWAP? Or is there an option to turn of DHCP snooping (which I suspect to be the cause of the issue)?

Sep 22, 2011Recently i had suffering with wireless connection problem, currently my wireless router connected to WAN directly, after that go into firewall and then go thru switch to end user PC, for LAN user there is no issue, but for wireless connected PC it is prompted with limited connectivity problem(DHCP is disable on router), after check with ipconfig /all. it seem likely due to wireless PC cannot get the IP from DHCP server. i am using DLink615 router. i had checked firewall setting there is firewall policy that connected all router ip into company LAN, but i don't think there is DHCP VPN setting up. is there anyway i can go thru firewall and get IP from DHCP server because if i set up DHCP on router, it cannot pass thru and access to LAN.

May 30, 2013I have a sg200-18 connected via one of the ports to my ISP's router/modem. Using an unmanaged switch everything works as expected, but after a few days on my sg200 my two computers fail to get assigned IP's and cannot connect to anything. I also have a couple printers that seem to have no problems getting their IP's passed through to the router as I can use them fine from my machines when connected to the unmanaged switch.
Is there a possibility I don't have my switch setup properly to know that all outgoing data must go to the router, or UDP traffic is being dropped somehow?

Cisco Wireless :: DHCP On WLC 5508 7.4.100.0 With HA
Jun 11, 2013We've encountered problem from the last few days with DHCP on certain SSID's. We have a wireless network with 13 SSID's being managed by a WLC 5508 pair configured as high availability (52 AIR-CAP3502I). Yesterday we encountered an issue with DHCP on a few of the SSID's but not all, and as a last resort a reboot of the controller fixed the problem. Statically assigning addressing allows for traffic to traverse the network out to the web and back so I don't think it's a VLAN configuration issue on the wired side. It's worth mentioning however that the controllers are configured for a LAG to HP switches. DHCP is being handled by an external windows DHCP server and the primary server address points to the gateway which has a relay configuration pointing to the windows server on the other side of it. Again, rebooting the controller fixed the problem and the web traffic traverses fine if statically assigning addressing.

Aug 22, 2011The two controllers are having two internal DHCP servers with the same range in LAN (enx1,enx2). but i have specified which is primary DHCP server(enx3) in WLAN interface.
Now if a new user added into network, will he get IP address from primary dhcp(WLC) or AP connected WLC.
if two users connected to 2 diff AP's which are connected to 2 WLC will get the same IP address? since having same address pool configured.
Cisco Wireless :: 5508 - WLC And Remote DHCP
Sep 16, 2012I am having trouble getting DHCP working for a site connected using Flex Connect. Here is my setup. I have a single 5508 Controller at one site using the 10.3.0.0 network. All AP's at that site are in local mode and use the local DHCP server, 10.3.0.2. Everything works fine there. Each site uses a different SSID as well.
At my second site, 10.4.0.0, all AP's there connect back to the controller at the site above and are in Flex Connect mode. The AP's work fine and the clients work fine there but they get an IP address on teh 10.3.0.0 instead of the 10.4.0.0 network. If i setup the SSID at this site to override the DHCP server settings and tell it to use 10.4.0.2, which is our local DHCP server, the clients don't get an address at all.Is this simply a matter of setting an IP Helper address on the router where the WLC is located or is there more to it than that?

Apr 22, 2012I have Internal DHCP Server configured on the Cisco WLC 5508 and all is working fine. DHCP Range is 192.168.1.100 to 192.168.1.245. Now I created another SSID but I want clients connecting to this SSID get specific IP's or from a specific range. WLC has no option to bind a DHCP pool to a specific IP so what I did I checked the option to "Override DHCP" and added the IP of my firewall WLC is connected to and setup a DHCP Pool on that firewall as 192.168.1.89 to 192.168.1.94 (192.168.1.88/29).
Client can connect to the second SSID but can't grab and IP address, what am I missing ?

View 5 Replies View RelatedCisco Wireless :: 5508 / Clarification On DHCP Server For WLC?
Apr 10, 2013Recently I came across a wireless design whcih I ws not able to understand.The design is:
1. Two wireless LAN Controllers 5508, each with 25 AP license. AP load (5APs per Contorller) shared between the WLCs and congured with Backup Controller option.
2. The design has a Data Center Switch 3560x series, on which the two WLCs, Cisco Prime Infrastructure and Cisco MSE were connected. I've attached the design here.
3. The Data Center Switch is configured with DHCP pool for the wireless clients. The IP Address of the Data Center Switch is : 10.xx.xx.2 and Default Gateway is: 10.xx.xx.1
4. On the WLC, the Management Interface is configured with the IP Address: 10.xx.xx.21 for Controller 1 adnd 10.xx.xx.22 for Controller 2. But, their DHCP Server is configured with IP Address: 10.xx.xx.1 but not with 10.xx.xx.2 .
This means, all the DHCP requests are pointing towards the Gateway of the Data Center Switch.Is this the correct configuration?I have seen the Wireless Clients getting the IPs allocated from the DHCP Pool, even though the Management Interface's DHCP server configured with Gateway IP address 10.xx.xx.1 .
The DHCP configuration for the Data Center Switch is:
ip dhcp pool xxxxxx
network 10.164.220.0 255.255.254.0
default-router 10.164.220.1
The Management Interface configuration on the WLC is:

Cisco Wireless :: Multiple DHCP Pools On 5508 WLC?
Nov 8, 2012I am trying to come up with a wireless solution for a campus deployment. The campus has ten buildings currently using Autonomous APs and are currently converting to Dual 5508 Controller model.
I would like to have a separate AP Mgmt subnet in each building, so I will configure an ip helper on the SVI on this vlan to:
Option1 - Point to the Internet Router configured with DHCP Option 43 with the controller IP addresses
Option 2 - Point to the Wireless LAN Controller itself.
Problem with Option 1 is that the Internet Router will now have to connect directly to the COE network to be able to route back to the AP mgmt subnets. So I would emply a VRF here to keep the separation.
Problem with option 2 is that there appears to only be one DHCP scope allowed on the controller. So this would mean a flat mgmt network across all buildings which I am trying to avoid. I know that after the AP joins the controller, I could change the IP and change the vlan on the port but this is not very neat.
So question is:
Is there a way of getting multiple DHCP pools on the controller?

Cisco Wireless :: WLC 5508 Internal DHCP Server
May 7, 2012I am hoping to get your feedback around the dhcp issues I am facing with Two Centrally Switched Wireless LANs. The setup is as follows:
- I have a WLC 5508 which has been configured with 4 SSIDs, out of which 2 are using Central Authentication and Switching. - I have an LWAP connected to the WLC in HREAP mode. - WLC is configured as the DHCP server for clients connecting to the SSID 'Guest'. For the rest, I am using external dhcp server. - Only one scope for Guest Interface is setup on the WLC.
Problems:
1. As far as I know, for WLC to act as internal dhcp server, it is mandatory to have the proxy enabled, but the Clients connecting to SSID 'Internet' are unable to get an ip address from the external dhcp server, if dhcp proxy is enabled on the WLC. If i disable the proxy, it all works fine.
2. DHCP does not release the ip addresses assigned to clients even after they are logged out.
3. If a machine which was earlier connected to 'Guest' SSID connects to the 'Internet' SSID, it requests the same ip it was assigned by the WLC which it was assigned under 'Guest', but gets tagged with the V LAN configured on the management interface.

Cisco Wireless :: 5508 Internal DHCP Server
Jul 21, 2012A client wants us to use the internal DHCP server on a 5508 instead of Windows DHCP. They will have 15 APs initially and upto 25 later. The docs on the 7.2 WLC make it sound like this is discouraged: Internal DHCP Server.
The controllers contain an internal DHCP server. This server is typically used in branch offices that do not already have a DHCP server. The wireless network generally contains 10 access points or fewer, with the access points on the same IP subnet as the controller.
In this case, the APs will not be in the same subnet as the Managment Internet.Is it a mistake to use the internal DHCP with upto 25 APs (3 WLANs)?
Cisco Wireless :: 5508 - DHCP Requests Starts Failing
Feb 15, 2013I have a school with 550 iPads. We are using two 5508 WLCs sharing the number of APs. The DHCP server and the default gateway for the network are on the firewall. The clients are able to get a DCHP. After some time, maybe about longer than a month, the clients are no longer able to get DCHP addresses. A reboot of both controllers takes care of this. Presently we are runing 7.2.110 OS. I am going to upgrade to the latest 7.4.100, and reload tonight.

Jul 22, 2012I need raise a especial configuration to 34 APs LWAPP associated to WLC 5508 with IOS 7.0.220
This is the Scenario:We have 34 APs LWAPP with 2 SSID (Corporative & Guest), with 2 DHCP different. The Guest SSID receive IP to DHCP from WLC while SSID Corporative receive IP from Microsoft DHCP. The AP On Site are Local and the Foreign AP are configured like H-REAP (H-REAP Local switching and Learn Client IP Address are marked)
Here is the thing, I need configure a new WLAN (Pruebas) for add to 34 APs (Local and Foreign) but this new WLAN must be receive IP from a New Microsoft DHCP
Firstly I configured a new Physical interface and linked to New WLAN (Pruebas) however i don't know how configure the AP and the DHCP because I want that the AP deliver IP addresses depending the Locality.The last because the SuperScope from DHCP is divided in various subnets and because the IP from the AP will be in another VLAN
Cisco Wireless :: DHCP In 5508 / Change WLC User Accounts Password Too?
Jul 24, 2012I just get to hands-on on my new WLC 5508?
1) I'm using a single subnet eg 192.168.1.0/24 for my wireless clients and i'm assigning them via the DHCP server from the WLC. As the clients are however made up of laptops and scanners, i would like to assign a range from 50-150 for the laptops and 151-250 for the scanners for easier identification. But it seems that from the WLC DHCP menu i'm not able to do this unless i segment them into a different network with different gateways.
2) Is there anyway to change the WLC user accounts password too? I dont seems to be able to find the option unless i delete the account and re-create it with the new password.

View 1 Replies View RelatedCisco Wireless :: 5508 Controller And Changing Windows Dhcp Server
Dec 5, 2012We have a 5508 controller authenticates with WPA2-enterprise to 3 possible AAA servers. Today I tried migrating our DHCP server from a Windows 2003 machine to Windows 2008 R2. Migration went smoothly and all wired clients could get IP's. Reservations intact, scopes intact, etc.. you name it. I though it was a great success.
Fast forward about an hour when people started coming into work for the day. Calls started coming in about their laptops not able to connect to the network. I double checked with a spare laptop in our IT department and also my iPhone. Same issue. Seems the only thing I changed today was the DHCP server (from 10.1.1.1 to 10.1.1.2).
After racking my head on it for awhile, I re-enabled the "old" dhcp server (10.1.1.1) and disabled it on the new (10.1.1.2). Instantly wireless clients were able to connect.
Am I missing some configuration step in the 5508 controller when moving DHCP servers? I do plan on running 2 DHCP servers (10.1.1.2 and 10.1.1.10) for redundancy once I get the primary one moved over and working correctly.
I want to decommision the older 2003 server. Its time to raise the domain functional level.
