Cisco Wireless :: 5508 WLC Designing - Interfaces And VLans
Oct 8, 2012
just have few questions about designing WLC 5508
The scenario is that currently one of the client has a firewall Tie ring T1 internet facing and T2 internal which has multiple DMZ connected.
T2 firewall has a DMZ switch connected which has a router which connects to MPLS cloud to different site across the country. (around 10 sites) all static routing.
Now the client is thinking to deploy wireless at all 10 sites using H-REAP. The issue is that client has only one WLC and they are not willing to buy other as i was thinking to deploy two WLC one for corporate and one for guest users. (one in internal network and on in DMZ)
Now my question is as follow.
1- Keeping in mind that there is only one WLC where should i physically put it?
2- How guest users will work ? How the authentication will be done?
3-There are 8 SFP ports in WLC how physical topology will look like?
4-How many Vlans i have to make for wirless users will that be 10? (1 at each site) ?
my last question is that how these ports work on WLC are they just like switch e.g one port can be assigned to different vlan....just confuse about interfaces and vlans on WLC (interfaces concept)

I am trying to configure two AP-management interfaces to accept CAPWAP on different ports using the option "Enable Dynamic AP Management". One of them uses public ip address. However, I getting the message "Ignoring discovery request received on non-management interface ..." on this.
I have a 5508-WLC appliance and configured multiple ap-manager interfaces to balance the join request from LAPs and the load.I went to console port from some LAPs and saw that there was that balance among multiple ap manager interfaces (Dynamic AP Management Interfaces). Then we torn down one of the ap manager interfaces and confirmed that the LAPs were moved to next ap manager interface automatically.But the question here is, how can I verify which ap-manager interface was used for a LAP from the WLC via GUI or CLI ?? or how can I see the amount of APs joined using that ap manager interface from WLC ?
I didn't design the job, but is pretty straight forward, except the following, the design has a single wlc 5508 with 2 physical connection between two non cisco switches. There are 2 initial WLANs to be created. I am ok with most of the wlc config execpt the following:
Now from my understanding of everything I have read recently, you can't use LAG on the 2 physical connections if they connect to 2 seperate switches, unless, although not offically supported, the 2 connections are on either 2 3750s in the same stack or a pair of 6500s running VSS. So I believe that in my case 2 seperate connections from the wlc to 2 non cisco switches will not work with LAG. Is my understanding of this correct?
Is there a way to maintain the 2 physical connections from the wlc to the 2 non cisco switches to maintain redundancy?The wlc will have a management interface obviously, but from what I have read, the 2 WLANs that are going to be created have to have their own interface on the WLC. Which I understand as the managment int and each of the 2 WLANs are on different subnets.
If I don't use a single uplink to one of the non cisco switches (either 1 or 2 physical connections) using LAG, it appears to me that each of the interfaces ( management, wlan1 and wlan2) need to have a physical connection from the WLC to the switch, with each interface mapped to a physical port on the WLC, so correct me please if I am wrong, but this would mean I need 3 physical connections between the wlc and the swtich?
ASA's G0/2 interface is connected to G0/1 interface of a 3560G switch in DMZ, below is the config and diagram
Switch Config int g0/1 switchport mode trunk switchport trunk encapsulation dot1q int vlan 1 ip add 192.168.0.100 255.255.255.0
We are running out of IPs in 192.168.0.X network and planning on creating sub interfaces on the ASA and trunk it to the switch so that we can have multiple V LANs in DMZ. Tried the below config in LAB but that didn't work, can you have a look at it and let me know if I miss anything. No change on the switch config since G0/1 is already a trunk port.
ASA Config interface GigabitEthernet0/2 description Trunk to DMZ networks no nameif dmz [code]...
If I change the V LAN on the switch from 1 to a different V LAN, say V LAN 50 for example, and configure the ASA accordingly its working fine.
I have a an ASA 5520 connected to a Layer 3 (3750) switch (Inside) and a connection to a 2960 switch (Outside) to get to the internet. . I have created vlan interfaces on the 3750 switch and enabled ip routing on the switch to enable the vlans to communicate with each other.
Vlan Interfaces on the switch: Vlan 100 172.17.1 Vlan 200 172.18.1 Vlan 300 192.168.3.1
I want the devices connected to the 3 vlans to be able to pass through the firewall and get out to the internet.I have connected the ASA to the 3750 by routed interfaces (10.10.10.1) --------- (10.10.10.2) and they are able to ping each other.I have also put a default route on the 3750 sending all traffic from the switch to the ASA inside interface (10.10.10.1)The issue that i am having is that the ASA also connects to a 2960 which has a connection to the Internet, and they are handing off an ethernet connection from the 2960 that sits in VLAN 55 (Vlan 55 is the Internet accessible vlan).How do I configure my ASA to send all traffic from my (3) vlans to the interfaces that connects to the 2960 switch?
I'm trying to figure out if it is possible to configure in one site a wireless setup that goes like this:
One WLC (5508), multiple LAP's in H-REAP mode.
AP's will be splitted in multiple VLAN's belonging to different departments but with the same SSID.Each VLAN will have it's own DHCP scope. All AP's are located in the same site and I need to know if it is possible to roam between AP's that belong to different departments?
On a WLC 5508 it lists an option to specify a "Backup Port" under the physical information section on an interface. We have two central switched SSID's which are connected to an internal firewall. We are looking at installing a backup/standby firewall and running a virtual firewall between them. Each SSID would have an additional patch from the WLC to the standby firewall.
Does the backup interface port function on the WLC allow traffic to be failed over from a centrally switched SSID via backup interfaces to an alternative device? If this does work will only physical link failure to the primary firewall cause the backup port to be activated or is there configuration parameters which can be specified for load, packet loss or latency which can be used as criteria to cause the backup port to be utilized?
I am trying to build a new network from scratch, I have the WLC 5508 w/ Aironet 3600e APs connected to my Netgear Smart Switches and a Linksys RV082 router that I'm using as my DHCP server with several VLANs for several stuff on my Switches.
I have 2 questions:
1. Can I have 5 Interfaces configured on 5 different VLANs, each SSID on each a different Port:
Port 1: Controller management only=> 192.168.x.x /24 Port 2: SSID 1: WiFi Internal=> 172.16.x.x/12 (Radius Auth with no sharing) Port 3: SSID 2: WiFi Internal w/ sharing=> 192.168.x.x/24 (Radius Auth with sharing) Port 4 :SSID 3: WiFi Guest=> 10.0.x.x/8 (Web Auth) Port 5: SSID 4: WiFi IT=> 192.168.x.x/24 ( Radius or certificate Auth with access to the controller management interface)
2. How can I use the Controller as the DHCP server for all the WiFi traffic, and how should that be configured to work with my other DHCP server?
I've got a new 5508 wireless lan controller and can ping the ip address of the management interface, but can't access the GUI at the management interface's ip address. I can access the GUI on the service-port interface. No static routes in the controller; trunk appears to be set up correctly.
I recently added a post lately referring to drawing a topology of a large network with a high number of hosts. Now with project itself, I'm designing a network for a large organisation with a different number of hosts at each location.These are, 500,18,52,236 and 12. The location with 500 hosts is the head office, to which every other branch has a wide area network connection through a serial link.How many subnets would I require? I wrote down subnet details, but only for 5 subnets, a subnet for each location. Is that all I need? Or do the WAN connections count as subnets
i am creating a network using the hierarchical for a small to medium business. basically i need, file server, sql database, web server, account server, app server, back able to use a phone. the network will have around 300 computers
I need to connect 4 desktops wired 2 laptops wireless, one led TV wired.I have beam 10mbps internet and I want to share it to all devices.I want one desktop to act admin for internet sharing on all other devices.
I am able to setup a vip on ace using routing mode on ACE,as the servers need to see the client ip ,so we are not performing SNAT,this part is working fine.
when a request comes from the client ,it goes to the vip and to one of the backend servers ,and the request will be forwaded back to the ace ,as the default gateway on the servers is pointing to the server vlan on ace.
but if the transaction from the servers need to go to the visa card transaction servers ,how can we acheive this ,and after fetching the data from visa servers,does the reply will be fwd to the ACE or ASAs directly.
I have a WLC with, let´s say, 30-40 AIR-LAP1142N-E-K9. Since last November the following issue happened 3 times. One of the APs (it´s always the same unit) remains online but both WiFi interfaces appear down. I´m unable to put it back UP like if they were disabled. Then i have to reboot the AP and it starts working again.
What could be happening? Should i open an RMA for this unit?
I have a customer who is going to deploy a WLC HA AP SSO setup. I have recommended them to have 4 Gigabit SFP modules in each WLC5508.The customer now asks if it is possible to only have one or two SFP modules in the standby unit ? As he says it is properly not going to go in service one time within the next five years if he is unlucky.
I have WLC 2504 controller and six access points AIR-LAP1042N. I reading Cisco 2500 Series Wireless Controller Deployment Guide url...trying to set up along the lines.
It is also possible to have multiple AP-managers in a different subnet than the management interface. However, in this case, it is recommended that you disable the AP-manager from the management interface and create another AP-manager interface on different physical ports in a different subnet than the management interface. All multiple AP-managers in this scenario should be in the same subnet.
I maping management interface on physical port 1 and disabled ap-manager on it. Set up 192.168.7.0 subnet with non tagged vlan. This iface/port I want to use only for access to WLC web-interface. Then I create dynamic interface ‘dynamic1’, map him on port 2, enable ap-manager on him, and set up 192.168.110.0 subnet with vlan 10. Then I tryed map wlan1 to this iface, but I can’t because in the choice was only management iface to map wlan1.
There is three dynamic interfaces on same subnet and vlan, in example above. But when I try to add dynamic iface with the same vlan/subnet as an existing dynamic interface, I get an error, and can’t adding.
I am trying to lab something up and I believe I am doing something incorrectly. My management VLAN works fine, the AP on port 7 finds the controller fine, but my VLAN 80 doesn't seem to be mapped to port 2. I mapped a test WLAN to the VLAN, and setup a DHCP scope, and a client can get on the WLAN, acquire an IP address, etc. I thought I coudl then map that VLAN (80) to port 2 and have it go out a cable modem. Doesn't seem to be working that way, however.
I've got a question concerning the configuration of multiple AP manager interfaces on -for example- a cisco WLC 2504. I've read the configuration guide but I'm not sure whether this is the way the protocol works. Say I want to distribute AP's (and traffic) across various AP Manager interfaces on the WLC. I would configure the following:
Create one management interface (which will automatically also be an AP-Manager interface)Configure 1 (or more) Seperate ap-manager interfaces, assign them to a port number, and select "Enable dynamic AP Management". VLAN ID's will be the same.Create a WLAN and configure it's interface to "management" Is it correct if I state that the LWAPP protocol takes care of the discovery from the Access Point and sends information about the available AP-manager interfaces back to the AP and the AP knows which ap-manager interfaces are available, connecting to the least loaded one?
I just converted AP 1142 to LAP using the image "c1140-rcvk9w8-tar.124-21a.JA2.tar".
The WLC is a 5500 with 2 NIC : one on 192.168.0/24, one on a specific vlan 10.20/16 The main management interface is on 192.168/24 but we defined as management the interface on the 10.20/16 network.
For the access points, we use ports on a native VLAN on 10.20/16 with other available VLANS which are used for the wlan networks
We have 1152 APs which work fine on this config but that needed to be registered on the 192.168/24 network, then we moved them in their VLAN 10/20/16 and they work fine.
We also have 1142 APs which have been upgraded to LAP. These AP do not work with our architecture. They register correctly on the 192.168/24 network, but do not give access to the wlan VLANs. If they are moved in the 10.20/16 network, they don't register to the WLC (message : Timed out while waiting for ECHO repsonse from the AP). The AP do not get an IP.
is there a restriction with VALNs on these AP ? or is something false ?
I am trying to setup a wireless link between two locations, and be able to pass VLANs through the Wireless link.Currently I have two 1310 bridges.I followed the information at url..., but it is only passing VLAN 1 across the link. I cannot figure what the problem is.Both Bridges are running c1310-k9w7-mx.123-8.JEA3. [code]
I'm trying to bridge two buildings with two WAP200E. The connectivity is fine, but I'm only able to get one VLAN through the bridge. That is the default VLAN 1 wich is untagged. I have two additional VLANs wich is tagged. I can not get these two through the bridge. I have set up a single SSID, and enabled VLAN. I have also tried to set up more than one SSID, mapping each VLAN to separate SSID's, but bridging several SSID's between two AP's make the AP's loose connectivity periodically. What would be the propper way of bridging several VLANs between two WAP200E ?
I have a Cisco Flex 7500 in my datacenter and I need to connect 100 sites , each site with 2-3 APs , each side has its own network and is independent of other sites , the site only need to comunity locally and do not need to access any centralized applications.
I am trying to achieve this by Creating 100 different AP groups and assiging 2-3 AP in each groups for each branch, I will achieve WAN failover resiliency by creating flexconnect groug , the issue I am facing are as below .
1.Since all the sites has same setup , the AP and clients on all sites are in vlan 2 , so when I try to create 2 or more AP group with same vlan, it restricts me of doing so , I cannot create diffrent AP groups mapped to same Vlan . 2.If I keep the APs and Clients in the same subnet , I dont think it should be a problem , but I need your second opinion.
to give you an even better picture , look at the topology enclosed , and my question is if both STAFF and STUDENT APs are in same vlan but in 2 different broadcast domain , how would I create the AP groups.
I have two Cisco 1300's acting as bridges only. I have created an infrastructure ssid on VLAN 2 and assigned this to the radio. I am carrying multiple VLANs between the bridges (using subinterfaces on the fastethernet and radio ports).I have enabled WPA-PSK, but how do I check that this is being used between the bridges? Also - I have a switch connected at each end of the bridge. When I make VTP changes, the remote switch does not pick these up - is this because VTP goes over VLAN1 regardless of the Native VLAN (2 in my case)? Do I have to carry VLAN1 over the bridge to get VTP working, or is there an alternative solution?
I've been searching high and low and although I've found many results of people having this same exact problem there doesn't seem to be a fix, or at least no one was kind enough to post one. I have many vlans but the 3 in question are 10, 20, 30.
-10 is for my laptops and desktops with an ip range of 192.168.10.10 - 192.168.10.50. -20 is my home automation network with an orange of 192.168.20.20 - 192.168.20.150 -30 is my guest network with a orange of 192.168.30.84 - 192.168.30.89
I have a dell powerconnect configured with vlans as my core switch. I trunked a port on the switch assigning 3 vlans (10,20,30) and connected it to port 1 on the wrvs4400N. On the wrvs4400 I trunked port 1 tagging vlan 10,20,30. For some reason vlan 1 is untagged on port 1 and I don't know why. I also have a router connected to the powerconnect. Of the 3 vlans I mentioned vlan 10 and vlan 30 are the only ones with interfaces on the router. Vlan 20 is an internal network with a separate router and until I figure this out that router is physically turned off. Also the router currently turned on has no routes configured to connect my vlans. Currently there is no configured way to jump vlans.
No matter what ssid I connect to I get a dhcp response from vlan 10. all my test indicates that I'm actually on vlan 10. I get internet and I can hit all devices on vlan 10. If I connect to ssid guest and change my ip address to match vlan 30 I can not ping the gateway for vlan 30 and I have no internet access. Some times I get something different. Sometimes I get an ip address from vlan 1 on the powerconnect. If I renew my ip address then I'll grab one from vlan 10 but I should be getting one from 30 or none at all for vlan 20. The absolute crazy part is my droid sometimes gets a 192.168.4.x ip address. I don't have a 192.168.4.x network or dhcp scope anywhere on my network! If I physically plug into a port on the power connect I get to the correct network 10 out of 10 times. If I configure vlans on the other 3 ports on the wrvs4400 and physically plug in, I get to the correct network 10 out of 10 times. I've reset to factory a few times and I've been all inside and out of the wrvs4400. I have no clue what could be wrong with this thing.
