I have two 5508 controllers configured with an internal dhcp scope. The scopes on each controller are a /22. I need to expand the scope to provide more addresses. Is there an easy way to add a second dhcp scope without making changes to the existing scope? If so how will the clients devices be able to access that ip address range?

Seems that all solutions are null and void for us because we are not using SNMP v3 or H.
We are using SNMP v2, We have upgraded our WCS to latest version as well as the controllers. I have 6 controllers currently added although they are on WiSM blades.
We are unable to add the 5508 Controllers, we keep recieving this error -
No response from device, check SNMP communities, version or network for issues.
I have confirmed all connectivity is working, even with a debug on the controller you can see it sending SNMP packets to the WCS, although still same error.
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.
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 3 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.
In 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.
ive got 2 laptops on my wireless network and have just bought a pc. it dosnt seem to be finding my connection so i cannot get it onto my wireless network?

Now I have to change the IP. I would like to change that very smooth with all our locations. My question, is it possible to add a ap-manager interface with a new vlan and IP Range, so that I can move the AP's to the second interface as as soon as it is planed with the location. Sometimes in special cases we have hard coded the WLC IP oder we just need to change the DHCP option but this needs to be planed and I see problem to do that in a hard cut.
Is there any additional configuration to be done on the 5508 WLC for Wireless Laptop / Voice Roaming? I tested with Wireless IP Phone and found some blankness in voice , whereas i have other access point nearby , which wasn't switching over easily .

I would like to use the 4404 (software rel. 7.0) as a guest anchor with a 5508 (software release 7.2) as the foreign controller supporting series 3600 APs. I ask because the APs do not need to join the guest anchor.

So far we add any router in the existing network simply by disabling DHCP server, and adding LAN ip for that. We don't add WAN detail at all in the additional routers. And plug one cable from main network to the LAN port of the additional routers.So we basically use that additional routers only as a access point for WIFI.But what I wonder is if it's possible for me to use the additional routers with the same feature as of the main routers i.e. Enabling DHCP server so that it too can give its own DHCP ip address.

View 3 Replies View RelatedWe have a WLC (5508) in our main office in Brisbane that is hosting two WLANs. One provides wireless access to our internal network and the second provides wireless guest access. The guest WLAN is anchored to a controller sitting in the DMZ at our Data Centre.
In the DMZ the anchor controller has a management interface and an interface in the DMZ for the wireless guest access. I am using the DHCP server on the anchor DMZ to provide IPs etc to wireless guest clients. The default gateway is 10.8.144.1 which is a VIP or a pair of firewalls.
Initially everything works fine. Guests connect to the guest network, have to authenticate via a web portal (Cisco ISE server) and then can go on an use the internet. Works perfectly until the firewalls fail over and the secondary firewall takes over the VIP address. All access to the internet is lost at that point. If I try to disconnect and then reconnect a wireless client it connects, as in it will get an IP address, but DNS resolution stops and I do not get redirected to the web auth portal. If the firewalls are failed back to the primary then everything works again, no issues. However, if I reboot the WLC while the secondary firewall has the VIP IP everything will work fine as it did on the primary. If the firewalls now fail over to the primary again everything goes to ****. Until either the firewalls are failed back or the anchor WLC is rebooted.
Initially I thought this was an issue on the firewall, but this doesn't appear to be the case. When the firewall fails over it sends out a gratuitous ARP advising of the change in MAC address for the 10.8.144.1 IP address. The WLC seems to update its ARP table because if I run the command "show arp switch" it has the 10.8.144.1 IP address with the MAC address of the active firewall. From the client perspective I have run a wireshark and captured packets on the wireless interface when trying to connect. The laptop is continuously send ARP requests for 10.8.144.1 but gets not reply. Without this the client cannot send an ethernet frame to the gateway and hence get to the DNS server and WEB portal. Internet access breaks. Doing a TCP dump on the active firewall shows it receiving and then sending a reply to the ARP request. It just never gets to the wireless client. Debugging ARP packets on the anchor WLC seems to indicate that the controller is receiving the ARP replies from the firewall. So I'm at a loss as to why things should break when the firewalls fail over.
I have a 3750 switch in the DMZ with SVI of 10.8.144.4. I thought I could get a work around where I would make this the default gateway. The theory being that this interface MAC address would never change. However I was wrong. Even with this IP set as the gateway address for the wireless clients I see the exact same bahaviour when the firewalls fail over. I can't explain it other than to say that the gratuitous ARP sent by the firewalls seems to kill the ability of ARP replies to be sent back to the wireless client.

View 8 Replies View RelatedSo we have a Cisco 5508 controller that is managing 15 AP's in one of our buildings.I am running 2 wlans, one is internal access via (wpa) radius, peap and domain login...that works well now
The other is a guest lan, that is only allowed to surf the web.
The question from our security group, is there a way to restrict wireless access to ONLY a corporate approved list of devices.
As it stands right now, we only support Blackberry's as our mobility device. All local data is encrypted. The issue here is our testing shows that with an Iphone (not approved) it is very easy to connect to the WPA network if a user knows how to enter in their domain credentials. From there they can browse our internal web servers and download corporate data to a non approved, non encrypted device such as the iphone.
I upgraded a controller yesterday 5508 it went from a low code version 6.x to 6.0.196.0 then to 7.0.116.0. However although all the access points joined code 6.0.196.0 they refused to join 7.0.116.0. The aps are all 1242s.
The country codes etc were all fine so I do not understand what was going on.
