Cisco Wireless :: New 5508 Not Handing Our Correct IP Address Scope To Clients

Jan 15, 2013

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.

Cisco Wireless :: 5508 - Clients Not Getting IP Address

Nov 23, 2011

I have configured 5508 with multiple APs but clients on the internal SSID aren't getting an IP address. I have the IP helper address configured and I have also disabled DHCP proxy on the controller.
 
I get the following from the client debug, I don't know what the below mac address is, it's not one my APs or the clients, I am not seeing this mac address on the controller at all but it shows up in the debug.

We got a question about our WLC 5508 single controller deployment with 14 access points without a VLAN configuration.
 
When our clients connect to the wifi, we cannot see any ip address of them in the client details page. It shows everytime the ip address 0.0.0.0. The clients are configured with a static ip.

Cisco Wireless :: 5508 - Same SSID With Different Dhcp Scope On Same Controller

Aug 10, 2011

I have a 5508 WLC controller at the HQ with the employee ssid ,the dhcp scope on the ssid is 10.120.0.0/16 network.
 
However,I want this same ssid to be brodcasted to a remote site using HREAP access point but with  different dhcp scope 10.102.0.0/16.
 
I have tried creating another interface for the remote site with a different dhcp scope(10.102.0.0) but the controller wont allow me create another wlan with same ssid that existed before to apply the new interface created for.

Cisco :: WLC 5508 - Clients Can't Obtain IP Address Via DHCP

Mar 29, 2012

I would like to share one problem with WLC 5508 . we added a new virtual interface on the WLC. One new SSID is associated with this interface.
 
We created a ACL for this interface to restrict the access via WIFI to certian services. It´s not correct that everything works fine because the change were not applied. [code]
 
The changes of the ACL are applied on the fly, but for reason we don´t know, the clients don´t get a DHCP IP-Address (after changing the ACL) until the Controller is rebooted.

Cisco Switching/Routing :: 5508 WLC And Nexus 7K - Clients Cannot Obtain IP Address Intermittently

Jan 22, 2013

I have a strange behavior between a WLC 5508 (version 7.0.116.0) and NEXUS7010.
 
WLC
The WLC is configured in DHCP Bridging Mode (it sends DHCP requests without change)
 
Nexus
The VLAN interface is configured as follows
 
interface Vlan501
  ip access-group acl-int-vlan501-in-1 in
  no ip redirects
  ip address 10.12.56.4/21
  ip ospf network broadcast
  ip router ospf 100 area 10.23.0.0
  hsrp 51
   
Clients can not obtain an IP address intermittently. If I deactivates the ACL when the problem appears(when the client can not obtain an IP@) the probleme is resolved
 
Note: Before the WLC was connected to Catalyst 6500 and worked properly for 2 years (with same configuration)
 
I saw this note about differences between DHCP relay on the NEXUS7000/NXOS an Ip helper one the 6500/IOS URL. Do you think the problem may come from the DHCP relay or ACL on the NEXUS.

Cisco :: 5508 VLAN Select - DHCP Leases On Each Scope For Same Client

Sep 11, 2011

The 5508 is running code 7.0.116.0.  I have created a group interface for 3 subnets and assigned the group to the WLAN.  Clients are getting IP addresses in a round robin fashion.  The issue or downside to this is if the lease has not expired before the next time the station connects to the WLAN it consumes an address on another subnet instead of grabbing the unexpired lease IP address on it's previous VLAN.  It seems that the WLC determines the VLAN in the interface group before the DHCP request from the client in case the client already received a DHCP address that has not expired.  This can be problematic since we have seen some iPhones requesting an address every 20 minutes thus consuming an address on every subnet in the interface group.  Other than setting a lease time extremely low what can be done to address this?

DHCP Assigning Address Outside Of Scope

Jul 1, 2012

I am using Windows 2011 SBS and Windows 7 clients.My server has a DHCP range of 192.x.x.150 to 192.x.x.199 and all other I.P. addresses are static. On a workstation located at I.P. 192.x.x.13 I am seeing an address conflict.When I perform an "nbtstat -a 192.x.x.13" command from the server I am given the logical computer name of a staff members personal laptop.Investigation of the laptop reveals that it is set to DHCP, and clearly the address of 192.x.x.13 is outside of my servers DHCP scope, so this I.P.should never be assigned, let alone in duplicate.I Google this topic before posting, and it was suggested that IPv6 could be having an adverse affect. I determined this because I performed a ping on the laptop and only got a MAC address back rather than an I.P. address.However after unticking IPv6, and rebooting, the laptop is still causing havoc.I can set a static I.P. address on the laptop, however this is not ideal.

Cisco Switching/Routing :: 120 IP Address From Incorrect Scope Is Assigned From DHCP

Jul 8, 2012

I am trying to setup VLANs and most of configurations are working ok now except IP address assignment from DHCP. If any computer in VLAN 120 or 130 configured with manual IP address, then all works fine. It can reach internal servers and the internet without problem.If the IP address is assigned automatically then any computer in VLAN 120 or 130 are obtaining  IP address (strangely!) from VLAN 100. Because switch ports that connected to the computer belongs to VLAN 120 or 130, the computer cannot reach internal servers and the internet with ip address from VLAN 100 . All SVI interfaces for VLAN 100, 120 and 130 have ip helper-address option defined pointing to the DHCP server. No DHCP snooping enabled on all switches at this point. DHCP server have three scopes for the three different VLANs.

Computer Not Using Correct IP Address

Sep 25, 2012

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).

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.

Cisco Wireless :: 5508 - Clients Dropping Connections

Jan 22, 2012

I'm having a problem with my clients dropping the network connection constantly throughout the campus. I am using a Cisco 5508 controller and the APs are LAP1141N. At first I thought it was a roaming issue but I tested with only 1 AP and the problem persisted, I can tell you that we don't have interference problems and that our old linksys APs used to work without flaws.

Cisco Wireless :: 5508 WLC Clients Jumping From AP To AP In Same Area

May 1, 2013

I have a 5508 WLC with CAP3502i APs connected to it.  I upgreaded the code to the newest 7.2.115.1 code.  I am having trouble with laptops that are not physically moving but are moving their connection from AP to AP in the same area.  This is in a school and causing a problem with a testing program they are using becuse they drop 2 or 3 pings in the process.  I do have the area heavily saturated with AP but that is because of the amount of clients we have connecting to them.  There is 8 classrooms in a hallway with 24 laptops in each classroom.  Each classroom has an 3502i ap in it.  The laptop can be connected to an AP with great signal and move to another AP that still has a good signal but not as great.  I don't understand why if I get 4 bars and connected at 144mps it would move to a new AP.  These are Lenovo laptos and i have updated their wireless card drivers and set the roaming agressiviness to low but it still happens.

Cisco Wireless :: WLC 5508 Clients Disconnect / Not Able To Reconnect

Jan 22, 2013

I have a WLC 5508 in my datacenter, and 1142s configured with FlexConnect at a remote site.Two issues:Some APs 'die' from time to time where I cannot ping them anymore and they do not service any clients. I can reset them from the WLC after which they work again. I have some clients in the building (same area) who lose connectivity from time to time and are unable to reconnect to the wireless. I am seeing errors that the gateway cannot be found or there is not a valid IP. restarting the AP closest to the clients fixes the issue. I have replaced the AP and connected to a different port on the switch.

Cisco Wireless :: WLC 5508 / SW 6.0.199.4 / 1142 AP / Clients Getting Dropped?

We have deployed a WLC 5508 w/ SW version 6.0.199.4, 1142 AP's & open authentication w/ MAC filtering. Clients are randomly getting dropped with "Limited Access" shown in Win 7. In this state, the client machine is unable to ping the gateway and sometimes lose their DHCP assigned IP as well. A manual disconnect/re-connect to the SSID is required everytime.I ran a debug on one the clients stuck in the "Limited Access" state (debug client xx:xx:xx:xx):

Cisco Wireless :: WLC 5508 - Get Clients Connecting On Network 192.168.3.0/24?

Aug 6, 2012

question in regards to the deployment of a new WLC and new LAPs,I have configured and connected a 5508 WLC and 3500 series LAP.LAG is enabled in the WLC and successfully connected to the neighboring switch (using etherchannel) and to the network.

The port-channel port is set to trunk mode obviously and certain vlan ids are currently allowed (3-5)

The management interface has this IP address 192.168.5.250/24

I created a WLAN with WLAN ID 3, Interface set to Management and say SSID test1

I have connected a new LAP to the network, which switchport interface is set to access mode and assigned with vlan id 3. The LAP is able to join the WLC successfully with an IP address, such as, 192.168.3.100 (assigned via DHCP).

When I try connecting a mobile client to the wireless LAN, it can successfully detect and connect to the WLAN, created in the WLC (test1) however it gets an IP address by DHCP, in the 192.168.5.0/24 network, which is the IP range of the management interface's IP address.

What can I do to get the clients connecting on network 192.168.3.0/24? I thought this would be the case since I allocated the WLAN Id of 3 in the WLAN test1 configuration and since the LAP switchport is set to access mode with vlan ID 3.

Cisco Wireless :: 5508 Dell Wi-Fi Clients Not Automatically Associating To AP

We have a Cisco 5508 controller with 1142 LWAP's running version 7.4.100.We have several Dell laptops which will not associate to the access point UNLESS you stand directly underneath it, power off the wireless, turn it back on then eventually the PC will associate to the AP.Once the PC is associated to the AP and user is authenticated then all is well.
 
Have tried updating the wireless drivers downloaded from both Dell or INTEL. This does not happen to all of our laptops. However, without making any changes to the WLC or the PC's, we have begun to expirence this problem with laptop which previously did not have this issue.

Cisco Wireless :: WLC 5508 Migrating With Clients Connecting To Old WAPs?

Aug 26, 2012

I'm working on migrating autonomous WAPs to lightweight mode in a WLC 5508. Some of the older WAPs are being decommissioned at the same time.
 
One issue I have found is that after replacing an old WAP in autonomous mode with a new WAP (3502); some clients near the coverage of this new LWAPP are now connecting to another WAP in autonomous mode that has not been converted or replaced yet; but that is located quite far away from where these clients are, actually two floors down. Users on these clients have reported wifi dropouts, which is obvious due to the distance where the old WAP is. A workaround that seems to work is removing the wifi profiles in the client machines and recreating them again, which is not a good solution for all of the wifi profiles we have in place. At this point of time we still need to have the older WAPs until they are all replaced.
 
How can I get clients connecting to a LWAPP that is closer to their location? I'm wondering what causes those clients to look for an existing older WAP rather than connecting to the new LWAPP, which is broadcasting the same SSID closer to where they aree. Bear in mind that the new LWAPP is working fine and has live sessions working just fine.

Cisco Wireless :: 5508 WLC - Clients Unable To Connect To WPA2 AES Network

I have a 5508 WLC and 40+ LAP1142N APs spread across 19 locations that allows staff to connect to our private network via wireless. I recently deployed about 40 new laptops all identical make and model HP ProBook 4530's and all have the same client setup for the wireless. Out of those 40 laptops I have 4 that will not connect to the private network. However, these same laptops will connect to my public, open wireless network without issue. In addition to the 4 that will not connect all the others will prompt twice for network authentication.Now, I have about 10 other laptops that are not the HP model and all connect without issue and without dual propt. I don't think this is a wireless network issue but could be some type of issue with this model of laptop.
