Cisco :: WLC5500 - Add Third DHCP Server To WLAN Interface?
Aug 2, 2012
I'm running a system that requires a third (and potentially fourth) DHCP server to be setup on each network in my network. The first two devices are Windows DHCP servers serving IPs from different address ranges for failover. The third DHCP is just a listener to receive OS information and device names to be logged in a database.
Currently this works like a charm for my wired clients as I can add in the third and fourth ip helper-address on each vlan and the information is received by the listeners. However, I cannot find anywhere in my WLC5500 to setup these extra two DHCP helper addresses.
The wireless vlan on my layer 3 switch has all the ip helper-addresses, but this doesn't seem to work, and the devices just use the DHCP servers set on the interface in the WLC.
I use the WAP610N as an Accesspoint for only an small Mobilephone to WLAN Printer Network.My big Problem is that i have therefore no DHCP Server in this special small WLAN Network.And now i need an own DHCP Server from the Accesspoint side because otherwise i must use static IP Adresses in all Mobilephones to connect with the WLAN Network .In the WAP610 unfortunately there is only the choose between static IP Adress and IP Adress FROM an existing DHCP server .
I've got a new CT2504 controller with software version 7.0.220.0 Regarding to [URL]I've tried to configure the internal DHCP on a dynamic-interface, but this is not possible:(Cisco Controller) >config interface dhcp dynamic-interface vlan401 primary 172.16.x.3 vlan401 Interface IP can not be used as internal DHCP server IP It works, if I use another IP (aka DHCP server) in the same subnet or in another subnet. It works also for the management interface.
Interface Name................................... management MAC Address...................................... d0:c2:82:xx:xx:xx IP Address....................................... 10.2.x.135 IP Netmask....................................... 255.255.255.240 IP Gateway....................................... 10.2.x.129
We've just started with the ASA 5505. We do run a DHCP server on the inside interface, so it is in the same VLAN 1 as all of the clients. However, we cannot get it to work.We can't use DHCP Relay, as the ASA 5505 only allows to relay to DHCP servers in a different subnet.Or do we have to move the DHCP server to a different subnet. If so, how would we configure that scenario?
How do i get the 12.4 code to assign a dhcp address to my ethernet interface from my server? I deleted the default config on the 1141 and searching has not turned up anything useful.
Started this morning woke up checked my phone no wifi hmm weird checked my hp tpuchsmart connected but jo internet access checked my router(netgear wireless N 300) made sure my modem and all wires are connectedNext went to my router ip 192.168.1.1 after reading some forrums i thought maybe if i changed the ip or sum i would have worked i know dumb though.. any way i believe i disabled my dhcp.. and one of the ip ad on the same page to 192.168.1.3 thats when it got worst i tried ipconfig/release saysNo operation can be performed on bluetooth network connection 2 while it has media disconnected.No operation can be performed on local area connection while it has its media disconnected(Its a wireless connection from my touchsmart to my router) I have tried goin back to the routers page but i can no longer find itI have also tried ipconfig/renew but i get this...No operation can be performed on bluetooth network connection 2 while it has its media disconnectdAn error occured while renewing interface wireless network connection : unable to contact your dhcp server. Request has timed out.No opration can be performed on local area connection while it has its media disconnected
Haveing issue with DHCP server handing out IP addresses to client connected to VLAN5 interface.ISP Router>Firewall -(WatchGuard Drop-in mode) I have several 3750 switches and one acting as a L3 switch. The L3 is configured as follow: [code]
If I connect a laptop to int fa1/0/10 I DO NOT get an IP address from the 10.100.0.8 scope. If I connect to another interface within the VLAN 1, I get an address from the 10.100.0.0 range.
We currently have a cisco 4402 with firmware version 6.0.182.0 and 4 WLANs currently running on it, we found the need to add an additional WLAN and after the configuration was completed and I tried to connect to it I found that we are not getting an address. If i connect a laptop to the VLAN I can get an IP and am able to browse. If i hard code an IP into a device and connect to the wireless i am able to connect and browse.
I have a Cisco Wlan Controller 2504 with 1042N AP (3-nos) every thing was working fine from past 2 months. Now i am getting a issue with clients which are connected to the wireless AP, they are not able to get an dhcp IP address from the 2960 Switch (DHCP Server). The clients are getting IP address as 0.0.0.0. [code]
I am struggling with the following issue. I have 6 1130 Accesspoints in lightweight mode connected to a 2106 wlan controller which runs software version 7.0.98.0. Everything seems to work fine. Clients can connect to the wifi network. However, they don't get an ip address from the dhcp server which is on the same subnet as the wlan controller. See attached screenshots for configuration. I have also tried the internal dhcp server of the wlan controller, but the same problem remains.
The logs says: Dropping primary discovery request from AP e8:b7:4x:xx:xx:xx - maximum APs joined 6/6 There are 6 AP's connected
I have a Question i am testing mobility group with Failover for redundend connection between 2 Cisco 5500 Wlc.On both the controllers i got the mobility working And both the controllers have the same version.And configuration. But when i unplug the main controller the access-Points don't convers to the second one .The just keep on creaming can't find the main controllerAlso with this thus the second wlc need to have the same.Interface ip address like management.
One of the SSIDs in WLC 5500 (SV:7.2.103.0) is configured in web authentication mode. After authentication (local database) users can access http sites and can't access, for example, https sites.
I have a question regarding to the maximmum number of active SSID's on a WLC 5500 with 3500i, it's my understanding that the 3500i can support 16 active SSID's is it the same when connected to the WLC? Also, if possible would the WLC shutdown un-used Radios or maybe after hours?
I have a WLC 5508 and several 1142 access points. The APs are not showing up in the WLC. When i console into the APs, im getting the following errors,
*Dec 26 23:04:28.035: %DTLS-5-SEND_ALERT: Send FATAL : Close notify Alert to 65.125.15.212:5246 *Dec 26 23:04:28.074: %CAPWAP-5-CHANGED: CAPWAP changed state to
[Code]....
Ive tried resetting the WLC, reloading the APs. I even factory defaulted one of the APs and still getting the same message.Ive verified that the WLC is set to accept MICs and SSCs.
The first is I have a laptop running XP with a Dell Wireless 1390 WLAN Mini-Card built in to it. But for some reason when I'm using that wireless connector my computer won't connect to my router and give me a 192.168.0.x address, it gives me a regular IP address. I can surf the net and everything but I can't access files on other computers. But from it it'll allow me to connect to the router admin fine.Whenever I put the mac address in to my DHCP setting on my router it comes up * RESERVED INACTIVE * and never gives my laptop a local ip address.The other problem is on my 192.168.0.2 computer I've tried to set up port forwarding but it won't open the ports. My router is a Motorola SBG6580 provided by my cable company. This particular computer is connected by Ethernet and not Wifi if that makes a difference.
I am able to obtain IP addresses through the DHCP server for my clients and I am able to browse internet on the server 2k8.Server 2008 - Share Internet through DHCP server
I configured a Cisco 881 as a vpn-client.When I configure the wan-interface with ip add dhcp , it never gets an IP-address.When I remove the crypto map from the wan-interface , the interface gets an IP-address without any problem.According to examples in the Cisco documentation, I should work; and it works on a 831.
I have an ASA 5505 configured to get a DHCP'd IP address from the ISP on it's outside interface. The problem I am seeing is when the ISP renews their IP address, the ASA 5505 is still holding on to the old IP address information. I have to either manually renew the IP or reload the ASA. I have the potential of rolling out hundreds of these devices and I would not like my customers to have to reboot their ASA everytime the ISP's DHCP lease experies. I am using an easy vpn autoconnecting to an ASA 5520. Static IP's are not an option on the outside interface of the ASA 5505's.
on the outside interface i cant perform the command ip address dhcp setroute.I get the error: IP and subnetmask form invalid pair indicating broadcast or network address.The commands are there when I do the ? command. It just will not accept the command with or without dhcp.I am trying to test an ASA-5510 as a 4G failover to our ASA-5520. This is Verizon's solution but they did not provide IPs, they use passthru on the 4G modem so I'm trying to set up dhcp. It worked a few days ago. Not sure what Im missing. The IP I got last time from Verizon was 192.168.0.199.
I have a 6509 with SUP2 w/msfc2 at home, I am currently have dsl for internet with static IP addresses. Due to AT&T not wanting to support faster speeds in my area, I have to look at another option. All of these will be dynamic IP addresses, cable, uverse, etc.
I need to be able to enable dhcp on the wan interface so I can connect directly into one of the gig ports (either on SUP2 or 6316) or on a 10/100 port on a 6348.
I have the following image installed s222-adventerprisek9_wan-mz.122-18.SXF13.bin, according to Cisco's feature tool, it is supported.
I have tried "ip address dhcp" on the interfaces but they will only accept "ip address x.x.x.x", I looked at "ip dhcp" as well and only get the option for "relay".
I would hate to have to put something else in the mix to handle the dhcp portion. I may be keeping the adsl for my mail server traffic and backup in case of an outage on the new provider. So I need to be able to track if a link is up.
Since I moved our WLC Controller ( 5508 ) from Version 7.0 to Version 7.2.111.3 I got above failure messages. Until now I changed the radius timeout from 2 to 10 seconds and also I disabled the aggressive failover without success. What else it could be ?
I've been running a cisco asa 5505 for quite some time and it has been running fine, now all of a sudden it starts to renew it's outside dhcp adress like every 2 hours. I dont think it's the ISP since I have another device connected also using dhcp to the same ISP and it doesnt renew itself, it's just the ASA. Rebooting it, makes it pick up an adress straight away. The interface seems to be up, the GUI just reports "no ip adress" and then the ASA get's a new IP after about 10-15 min without one. Pressing the renew IP adress button in the GUI throws an error.
I currently have the managment interface set to my internal network using our DHCP server. We also provide another interface to WLAN for a chartity organization. Their interface and WLAN are locked out of our network (no routes, no nothing) with only VLAN tagging sending out over our backup internet connection. I have been tasked to take over their DHCP scope (255.255.240.0). I added the scope into the 4404 just fine but can't seem to assign it. So, for the sake of argument lets say:
If I tell the charity interface to use 192.168.160.2 for the dhcp scope it errors out. I also tried the DHCP override in the WLAN with no success. If I set either DHCP option for the charity to aim at the managment interface it does nothing as it can't find it..
I've been using this setting for clients in small offices and what not, and since all they wanted was to give another nutch of security to their network, we've been intalling cisco routers 2600 series still outhere for their internet connections and we had no issues what so ever, not until we run into cable isp provider, and their dhcp wont be able to assign our interface a dynamic IP, this is the setting aplied to the router interface;
interface fastethernet0/0 ip address dhcp ip nat outside no ip redirects no ip unreachables no ip proxy-arp
Why it wont be seen or assigned an ip by their dhcp, I talked to their isp and they assigned a static ip (private one) and we still have the same issue, if i connect a pix 506e interface with the ip add dhcp assigned to it gets a dynamic ip right away...
We have a Cisco 886G router connected to the internet. The router receives an ip address. We experience however a problem when the lease time expires. The router does not send a DHCP request to renew it's ip address in time. This causes an interface reset, and connectivity loss, after the lease time of 8 hours.
We are running IOS 880data-universalk9-mz.151-3.T.bin. Config on DHCP receiving interface is:
interface VlanX description To Internet MODEM ip address dhcp ip access-group TEST in!
i have a adsl modem that is sending dhcp reqeust and i want to use that on my cisco switchs 3560 48 ports.i want to use the interface port 0/48 as a WAN connection and i want to use the other interfaceports for DCHP pool.i have an d-link (dir655) router at home and i want to have the same situation on my cisco switch my WAN interface get from a DHCP reqeust an ip adress from the provider like 10.10.123.44 (for the cisco switch would this interface port gig 0/48)then i want to configere my LAN as a DHCP pool like 192.168.0.1 (for the cisco switch would this interface port gig 0/1 - 47 .
i have WLC 5508 showing the below Logs , which prevent the users from connecting to the SSIDs , also its disconnecting the associted users DHCP Socket Task: Jul 11 09:54:08.992: %SIM-3-DHCP_SERVER_NO_REPLY: sim_interface.c:1039 Failed to get DHCP response on interface 'interface-02'.

I would like to configure the 881G to use both the cellular interface and Fe4 WAN port for internet connectivity.Interface Fe4 is connected to an ADSL router.
I have configure each interface with a default route and weighting:
ip route 0.0.0.0 0.0.0.0 Dialer0 200 ip route 0.0.0.0 0.0.0.0 FastEthernet 4 100
I need to configure Fe4 to get an address as a DHCP client:
interface FastEthernet4 ip address dhcp no shut duplex auto speed auto
How do I remove Fe4 from VLAN1? There is some existing config around VLAN 1:
interface Vlan1 ip address 10.73.0.1 255.255.255.0 ip helper-address 192.168.140.13 ip tcp adjust-mss 1400 no autostate ip sla 100 icmp-echo 10.64.4.15 source-interface Vlan1 tag 3G Keepalive frequency 10
Then I guess I need to adjust my Internet-IN ACL to allow broadcasts and UDP 67 and 68?
