I've just installed a 2106 Controller at a remote site. The Controller is seen by the WCS at the main site so, connectivity is good and I'm able to login from the main site. I've configured the DHCP server which is at the Main site on the AP manager interface and the Manager interface and on the WLAN of the new controller but, APs are not getting addresses.

I've created a tonne of dhcp scopes on my routers before never had any issues, however this one will not hand out any addresses at all, i even give the router a reload to see if any magic happened but nothing, ive ended having to put a temp server in with just dhcp installed until i get the router diong what it should my config below, its something simple i havent seen, as ive compared it to plenty of my working DHCP configs and seen nothing.

View 9 Replies View RelatedInitially there were 3 SSIDs configured but all of them were assigned a single interface and this interface was configured with the controller management IP address as DHCP server so that the WLC could assign IP addresses to wireless clients, guns and printers etc.
Issue: As part of PCI initiative, we decided to segment the traffic in multiple subnets based on type of wireless clients; so now there are 3 interfaces configured and each SSID is assigned a specific dynamic interface and each interface is configured to use the controller management IP address as DHCP server.
There are 3 scopes configured for each of the dynamic interfaces/SSIDs and DHCP proxy is enabled but wirelss clients are still being allocated IP addresses from the original DHCP scope that was associated with the dynamic interface originally assigned to all 3 SSIDs.
I verified the following:
1. Each SSID is assigned a different dynamic interface (Users, Voice and Handhelds)
2. Each dynamic interface is configured to use controllers management IP address as DHCP server
3. DHCP scopes configured with correct network information for each dynamic interface and enabled
I recently upgraded a clients WLC and they keep saying they are unable to get an IP address from the DHCP server. It's a simple, flat network and here is what the logs are showing.

I have a LAP1142N that is connected to a 3560 nonPoE switch (using compatible power injector) that will not associate to the controller I have set-up. The wireless is existing and I have about 11 other APs connected to the controller with no issues. The AP will pull an IP address from DHCP running on the primary controller. The AP pulls a new IP address in roughly a minute. I set the pool to be 3 IP addresses and set a contant ping to each, there is about 1 request time out before the next IP address starts pinging. I went to the controller and pulled the following message error from the log.

I have tried a different cable, connecting to a PoE switch, different controller, larger DHCP range, hosting DHCP on the distribution switch, I am awaiting console access to the AP since this is remote work. The controller is running Software Version 5.1.151.0. Thoughts?

View 9 Replies View RelatedI have a Belkin model F9K1102 router supplying WAN/LAN connection to three PCs and 2 laptops. Two of the PCs are hardwired with the remainder PC and laptops are wireless. I'm using the default router IP of 192.168.2.1 and my ISP is Charter Cable (if that's of significance). The router is picking up all the dynamic IP information from my ISP and internal DHCP is enabled. Here's the issue though - when I connect a PC, laptop or iTouch (wired or wireless) with obtain IP settings automatically enabled the IP address it receives an IP address on a different subnet ie, 192.168.3.x and thus won't have WAN/LAN connection. I have tried to set the router IP to 192.168.3.1 and set the scope in the .3 subnet but the IP obtained by the device is .4! This makes no sense to me at all. The router is on the latest firmware (according to Belkin) and there doesn't seem to be any other update I can find. I have also tried another Belkin router (older model: F5D8236) and it does the same thing.
I'm not sure if this is related but I upgraded my service with Charter to a 18MB connection and a D3.0 Ubee cable modem - this issue seem to have began after this upgrade but I don't see how that would have any bearing on what is happening on my LAN IP scope and Charter tech support is pretty useless. My workaround is that I've static assigned an IP for each device in the same subnet as the router but it would be nice for the DHCP to function correctly.
I imagine I can use the framed-ip-address attribute to assign ip-addresses but there seem to be support for static ip addresses only?A bit of a drag when we're talking 200+ nodes.

View 3 Replies View RelatedI used to use a CentOS self-made server for intranet for my little office, but I bouth few days ago a Cisco 861 router to replace the linux box.
1. I have 2 public IP classes from my ISP. 1 class is limitted to 80mbit upload, the other to 30mbit upload. So I need some sort of DNAT to be able to know exactly which intranet computer uses big internet and which one limitted internet.
2. I need DHCP server and with static IP addresses (one computer must always have the same IP address, etc).. i have my needs for this.
3. Also I need external access to some servers inside (web, ftp, etc) [code]
So far so good, all looks simple and I can achieve this in 2 hours on a centos linux box (correct routes, ip forwarding enabled and few iptables rules for NAT/SNAT/DNAT).
But on this brand new Centos router well, i'm not even successful in pinging the outside world, nor the inside world I'm tired of reading the forums, the documentation..i want (at first) a simple scenario: vlan+dhcp, fa4 with 1 public ip address and ACCESS to the real world. I wasn't able to achieve not even that much. [code]
Had a problem with a 3750 this morning not handing out DHCP addresses. The following is a sanitized config of what the switch is using. [code] The IOS installed on the switch is c3750-ipbasek9-mz.122-55.SE1.bin. What got my attention was that the sh ip dhcp pool PC showed 180 addresses being excluded. In doing the math from the dhcp excluded addresses, only 64 should be excluded.
My next step was to remove the second dhcp excluded-address line above. Doing a clear ip dhcp binding * started letting the DHCP service hand out addresses but the sh ip dhcp pool PC stil showed 180 addresses excluded.
It finally took removing the dhcp pool and putting it back in to drop the number of excluded addresses down to a value that matches the first excluded-address line. Didnt see a dhcp bug in the bug database that would explain this.
I tried re-entering the second excluded-address line from above and saw the number of excluded addresses rise as expected. When I negated the line, the number of excluded addresses dropped back to its previous value.
A small network and uses the Linksys Router BEFSR81 as dhcp.the default Number of addresses is 50 and starts 10.0.0.100 to 10.0.0.149.A new Cisco IP Phone just introduced requires ip addresses and have noticed running out of addreses.Can I increase the number to 120 so that the address range would start from 10.0.0.100 to 10.0.0.219, also, I have a VPN device which automatically configures itself for 10.0.0.199 address and this is /24 network configuration.

here's the problem, wireless clients connected to WLAN guest keep getting DHCP leases from WLAN local 10.0.50.10 (scope 10.0.70.101 to 200)
Here at HQ we have a 4402 WLC. At our remote sites we have 1231G APs running in autonomous mode. I upgraded one of the APs -- IOS 12.4(3g)JA -- to run LWAPP. Per release notes I've read upgraded 1231's do not support REAP/HREAP mode, consequently, it's running in LOCAL mode.
The AP is managed by the WLC. I created a WLAN for the remote site and assigned it to the MGMT interface; the remote site subnet doesn't exist in HQ. The DHCP server for the remote site is presently at that site; AP and DHCP server reside at the same place.
Clients authenticate successfully to the remote site AP, however, they are not getting DHCP addresses assigned. Does the DHCP server for the remote site have to reside in HQ since the AP is running in local mode? If so, where is that specified, on the MGMT interface config?

View 2 Replies View RelatedI have a Wireless N router model F5D8236-4 v2 (01) with firmware 2.00.04 (Nov 12 2008 10:51:08) and it's not showing all issued wireless or Wired IP addresses in DHCP Client List.
They all have IP addresses and connect to the internet through the router, but in the router administration page, they're not listing. The Windows devices all show but most of the Mac devices are not, nor is my XBox 360.
My reason for investigating this is because the router seems to keep losing the Mac devices and a router reboot fixes it, but it shouldn't have this problem because all the Windows devices just seem to work.
According to the support page I have the latest available (dated November 12, 2008 which really seems kinda old to me for a Wireless N router). Are there any plans for a new firmware offering for this modem or have you already deprecated it as "legacy equipment"?
Setting up a stand-alone WDS/PXE server.Current we have helper addresses setup to forward the DHCP requests from the different VLAN's to the DHCP server. The WDS/PXE server we are setting up is on its server. How do we craft the helper addresses so DHCP requests go to the proper server hosting DHCP and PXE requests go the WDS server?
Everything I seen on Microsoft Technet, lists using Helper Address as the recommended way, but assume both services are on the same server. Our helper address is as follows on each VLAN interface in router: ip helper-address X.X.X..This is a Cisco 3750.

I'm having issues with DHCP server not dealing IP after few hours (varies between 1h and 8h) of torrent traffic. If no continuous torrent traffic is applied, the problem does not occur. New wireless devices connect to the wi-fi network, but get stuck on 'getting IP adress'. The problem is with DHCP service or the wireless network service. New wired devices receive IP. The problem is only with wireless devices. I have no additional wireless device, that I can configure the network settings on my own (only phones) to check if it works without DHCP server giving IP. Wired connection is stable, but the bandwidth usage curve becomes somewhat similar to a sinewave.
I did disable the hardware NAT because that feature made the router unstable and caused it to hang up within minutes.
Is it possible to assign IP addresses to remote site WIFI users from local DHCP server and forward all other traffic to 2504 WLC?
