How to disable dhcp proxy on controller and what is the impact of doing it in the middle? We tried once by giving 'config dhcp proxy disable' command but seeing virtual ip again.(likely it gets back to proxy mode). We also have ip helper address on the L3 interface. We have only external dhcp servers configured..
View 5 RepliesI have a DHCP server on a WLAN that does not support Cisco's native proxy mode. I need to use DHCP bridge mode for that WLAN only.
How do I disable DHCP Proxy and switch to DHCP bridge mode for one WLAN ?
While configuring a 5500 wireless controller, i came across this option of DHCP proxy under Advanced tab of Controller Option.It asks for the dhcp option 82 remote id format & the dhcp timeout.
1. What is the significance of this & when do we use it?
2. Also, under each wlan ssid that we create, there is an option of dhcp address required under the advanced tab. Do we need to use this option, if we are defining a normal dhcp pool in our controller for that ssid.
Continuous dropping out some of them Access Points registered on the Primary Controller . What is the reason for this. We have a problem the last 2 weeks. What are the causes of falling out controler Access Points. The problem does not appear from logs. 70 LWAPs registered over Primary Controller. All AP mode is Local.
Primary controller model: WLC4404 SW:7.0.116.0
Secondary Controller: WS-SVC-WISM-1-K9 SW:7.0.116.0
Tertiary Controller: WS-SVC-WISM-1-K9 SW:7.0.116.0
AP models: LWAP-1131 LWAP-1142 LWAP-1242 SW: 12.4(18a)JA3
I'm configuring a 2504 wireless controller with # of 1142 APs, wondering is there an option to turn off the WLC/ APs during after ofice hours? such as turn off power/RF options etc

View 36 Replies View Relatedi have 2x WLC4404 they are in the same mobilitygroup and worked since a long time. Three days ago, ill upgraded one of them from 6.0.199.4 to 6.0.202.0. I have nearly 90 APs (1231,1242, different models)
The upgrade was successfull and i moved the APs from WLCA (6.0.199.4) to WLCB (6.0.202.0) almost all APs worked fine without 6 of them. This 6 APs cannot ping the AP-Manager-Interface from WLCB. But they can Ping the Router in this vlan, WLCA-AP-Manager and all APs in this subnet. They only cant get to the AP-Manager-interface from WLCB. Ping to Managementinterface of WLCB is also ok. Management and AP Manager are in different subnets. All APs and the AP-Manager-Interfaces from WLCA+WLCB are in the same subnet.
Switchportconfig and routing are ok. ive resetet the APs to default, checked switchport config, resetet switchport, power down ap for a while. ive tried many things, but nothing worked.I ever only can ping AP-Manager from WLCA, but not WLCB (again same subnet, and about 80 other APs work fine)
If i install a new AP on the same switchport, it works fine, without any issues. when i than unplug the "newAP" from this switchport and again connect the "oldAP" it can ping WLCA+WLCB and anything is fine.
Now i have the next and bigger problem nearly 15 of the APs that worked fine after upgrading, for now 3days+. Now they cannot ping the WLCB-AP-Manager-int too. And they dont failover to the WLCA with (6.0.199.4), i can reboot but they ever try to connect to WLCB. But they know both controllers.I only can get them to WLCA via ssh: capwap ap primary-base WLCAsname WLCAsmanagementIP..why the APs dont fail over if they dont reach WLCBsAP-Managerinterface?why i cannot ping WLCBs AP-Mana-Int from some APs.
I need support for wap4400n and I did not find it in the user guide and the administration guid.Is it possible to disable DHCP in this product? I want the wap4400n Access Point to distribute DHCP from the windows server.
View 1 Replies View RelatedI 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.
All controllers are in version 7.2.111.3.C1 is a 5508, it is ou anchor controller.C2 is a 5508, it is a big site controller.C3 is a 2504, it is a small site controller. C2 and C3 are in the same mobility group than C1 (and all is up up in mobilty managment). When "DHCP Addr. Assignment" is enable on C1 : Clients on C2 received their IP address by our external DHCP server via C1 and the guest tunneling betwenn C1 and C2 and all is working fine. Clients on C3 don't received their IP address by our external DHCP server via C1 and the guest tunneling betwenn C1 and C3, so nothing work.
View 4 Replies View RelatedI am trying to setup a guest vlan. I set up an interface for the guest vlan on my 4402 controller. I assigned the guest vlan interface an IP of 192.168.2.10 with a 24 bit subnet mask.
This vlan will go to my DMZ where there is no DHCP server so I need to setup the internal DHCP server. I created a new scope but I'm having trouble with what to put in the Network field for the DHCP scope. The pool addresses are 192.168.2.100-200. with a 24 bit subnet mask.
Every time I try to apply the configuration I get an "error in setting DHCP scope network and netmask".
I've tried using:
192.168.2.10
192.168.2.255
192.168.2.254
as entries for the Network setting but no go. The docs say to enter the IP address used by the management interface with subnet mask applied.
I was assuming they meant the interface for the guest vlan.
how to set up support 802.11n on WLC4404 or WLC5508 in the 2.4Ghz? WLC4404 supports 802.11n? or support this protocol only in the brochures? I spent a few days, but did not get the result. I'm connected at speeds 65/130Mbit, but the real speed tests never exceeded 45Mbit. The AP from the test laptop is 7-10 meters.I tested the laptops with a Linksys AP E1200-EE ( 40Mhz, FastEthernet uplink port...)and received nearly 100Mbit!
At WLC5508 able to connect at speeds 150/300Mbit/c but only in the 5GHz band, but real speed tests never exceeded 70Mbit.In 2.4Ghz range I connected at speeds of 130/144Mbit/c, but actual measurements showed no more than the 45Mbit.

We currently have about 50 Cisco 1252 wireless access points running from a 4404 Wireless LAN controller. We need to order more APs, but of course the 1252s have been discontinued.Was assured by Cisco that the 1262 would work just fine with our WLC. I'm messing around with a trial 1262 and am running into problems.We hard-code the IP address, hostname, default gateway, and controller IP address in each of our access points. I did that with the new 1262 the same way I did with the 1252s:lwapp ap ip address lwapp ap ip default-gateway etc., etc.That didn't work. Then I tried doing the same thing using (not sure if this is the correct terminology...) the capwap commands.
The AP still doesn't show up on the WLC's GUI, though I can ping the AP from the WLC and I can ping the WLC from the AP.I also can't use a web browser to get into the access point's configuration tool. Do I understand correctly that the lightweight APs don't have the GUI?
I am currently configuring my new SRP546W on my network and I need to disable DHCP I dont want clashes with IP's from my current DHCP server on my network.

View 1 Replies View RelatedWe 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.
I've purchased a router SRP547W and I would disable DHCP server. On the control panel I can't see anything about disabling this function. I don't need dhcp server on router and I don't need dhcp relay. My firmware version is 1.2.4_003.

View 8 Replies View RelatedWe have an SRP541W on which I thought I had disabled DHCP, its turns out that in fact I haven't. After seaching again for the DHCP on/off funtion I found it under the Vlan settings (Wierd place to put it I thought).
The Router has a static ip address on the LAN side of 192.168.1.254 and is connected to a Cisco 2700 series on the WAN side. Our network DHCP is served by an SBS 2011 server hence my reason to switch off DHCP on the router. However when I select Static IP address from the Address Type in the VLAN settings and try and save the changes I get an error that is IP Address / Subnet Mask value is illegal. Great but why when the router has and IP address assigned and the subnet mask is set do I get this error. On the VLAN settings page there is no option to set an IP Address
Due to lack of wires we decided to extend our network by using WET546 bridge by linksys. Ideally we looking to create topology like this:
(Computer)--eth--(WET546)---wireless----(AP/WLC2100)---(router)---(Internet)
WET546 successfully authenticates and looks pretty healthy on controller (see below) , however neither of computers plugged to WET546 was unable to obtain ip address from dhcp server , nor working with static ip. I was under impression what it might be related to some default policies on WLC2100. Logs (warning) on WLC2100 looks clean.
I'm adding some additional AP's (3502s) to an environment that is all 1131AG AP's. The DHCP is configured for DHCP option 43 for remote sites for layer 3 discovery. Since only one AP mode can use option 43, I've added a DNS entry for cisco-lwapp-controller in my local domain.My assumption here is that the new 3502's will be able to use DNS for discovery, while any additional 1131AG would continue to use DHCP option 43. will this work in a mixed environment?The new AP briefly showed up on my controller, but then disappeared. The LED is cycling red, green, off - indicating it is still in the discovery process. Could I effectively remove the option 43 in DHCP and have all AP's use DNS? Is this as reliable as option 43? What is the best practice for discovery?

View 35 Replies View RelatedI have ASA5505 as my main router (192.168.15.1) and it currently it also serves as DHCP server. I have a WNDR3700 (192.168.15.2) which work as an access point and it provide wireless access for wireless devices. I have few dhcp clients where i can't setup static IP, and i want to restrict them to use static IP through MAC reservation.
1. Make ASA5505 to do the MAC reservation f, which will be easy setup for me. But as per my search its not possible.
2. Disable dhcp on ASA and enable dhcp on my WNDR3700. i tired this and dhcp clients are getting IP from wndr3700, but the problem is dhcp clients gateway defaults to 192.168.15.2 (as well as dns) and therefore no internet connection.
The operation steps on router (WRVS4400N):
1.Set the IP mode as Dual-stack IP and then save
2.Disable the IPV4 DHCP server
3.Use other deivces to connect the router.
The connected devices have the same IP address(2005:123:456:789::1),I am confused,why is it?
Can you confirm that if I want to disable temporarily a dhcp pool on a 4500, I need just to shutdown the interface VLAN corresponding to a specific dhcp pool?

I have a BEFSR41v2 and have since upgraded to a wireless router. I now need a hub and have read that I can disable the DHCP in the BEFSR41 and use it as a hub. If I understand what I've read, I hook the cable running from my current wireless router into the uplink port on the BEFSR41 and then have the 4 ports available for expansion without using the WAN port - does this sound correct? Also - should I have the router (now configured as a hub) set to obtain the IP address automatically, set a static IP address or what? Finally - the firmware is the original firmware 1.42.7 (April 2, 2002) and I've read where people have problems after updating the firmware.
View 9 Replies View RelatedIn our test set up, we have two WLC 5508 Controllers connected via Checkpoint UTM-1 firewall Inside and DMZ Interfaces. Both the WLC controllers are connected to the firewall via Cisco 3750 switch. On the Local (Inside) Controller, guest SSID is enabled and attached to the wireless management Interface. On the remote anchor controller, guest SSID is enabled and attached to the Management Interface as well. The following configs are replicated on both the Controllers.
SSID Name - guest
Interface - Management ( VLAN 10 on Local and VLAN 20 on remote) -
Mobility Group: Same configs at both ends
SSID Anchor : Anchor SSID on local and local SSID on Anchor.
AP: CAPWAP 3502 Management Subnet
[code]....
Is there any thing missing in the wireless configs and or the firewall rules as i could not see DHCP request back from the Anchor Controller. Also, after DHCP is obtained, the web authentication request will be redirected to an Amigopod device for authentication. In this case is the redirect URL congiguration to be performed only on the Anchor Controller or is this to be replicated on both the Local and Anchor Controllers.
