Cisco :: 5508 - Forwarding Management Traffic From WLC

Aug 4, 2011

I am trying to forward mgmt traffic from my WLC (5508) to the NNM server. The WLC it self comes in to the mgmt server, but i dont get any snmp traps/message from the Accespoints
Is there some configuration I have to do ?
I have checked the community strings,trap receiver etc, but the WLC is showing up in the mgmt server so i think those parameters should be ok.

Cisco :: 5508 - 802.1x Authentication On PSK Key Management?

Aug 20, 2009

I'm setting up a new 5508 WLC (the first wlc I have ever setup) and I have my WLAN setup with our existing WPA/TKIP ssid for transitioning our clients from our existing autonomous system to the wlc.  I have selected PSK as the key mgmt and I can get the client's to connect for a few minutes but I keep seeing these errors:
Fri Aug 21 08:50:05 2009 Client Excluded: MACAddress:00:21:00:f9:dd:50 Base Radio MAC :00:23:eb:27:e3:b0 Slot: 1 User Name: unknown Ip Address: unknown Reason:802.1x Authentication failed 3 times. ReasonCode: 4
I don't have nor do I want 802.1x enabled.  Is there something I need to disable either on the client or the controller?

Cisco Wireless :: 5508 WLC Management?

Apr 24, 2013

I have a 5508 deployed, what I'm trying to do is configure it so that it can be accessed with AD credentials, I'm not talking about accessing the wifi network, I'm talking about logging onto the controller itself for management purposes. We havea  few people our team, and it would be alot easier if each of us could log into the controller with our own AD logins. Is there a link that can assist me in accomplishing this, I haven't been able to find one.

Cisco Wireless :: Bandwidth Management Using 5508?

Aug 16, 2012

I setup a WLC5508 with 2 SSIDs, one for guest traffic and another for internal users.  They are in separate subnets and are routed out to the internet via 2 different isps, with the guest network going over a bonded t1 and the internal users going out the primary internet connection for the company.  While this works as desired and we've verified that while on the guest network we're going out the right isp, we've encountered an issue with saturation of the bonded t1 pipe by guests.  We'd like to find a way to limit a guest to a capped down/up stream if possible, with downstream being the most important.  The infrastructure includes 3560 switches and AIR-CAP3502I-A-K9 access points.

Cisco Wireless :: 5508 Controller SNMP Management

Jun 10, 2013

We faced one recent issue with WLC configuration behavior and explaining our observation and workaround we did.Requirement is to manage the WLC (5508 with 7.4 code) using two SNMP managers in different locations. Also these two Servers should use the same community string to manage WLC. 

We were able to configure the SNMP community string for one server IP (to allow access) through GUIWhile trying to add another Server – IP with same community string – it didn’t allow As per the configuration guide, Controller can use only one IP address range to manage SNMP community. So we cannot configure the same community string to allow only two different server IP addresses [code] We currently configured the major subnet ( 10.x / 8 - two match both server addresses) and it works fineAlso when we tried / , it didn’t work (SNMP was failing)But this creates a security issue wherein anybody can poll the WLC.

Cisco Wireless :: WLC 5508 Management Interface Connection

Aug 1, 2010

I'm setting up a new 5508.  I've used the config from a 4402, have successfully connected to the Service port to manage the device, but for some reason cannot connect to the Management interface.  In this case, port 1.
The service port is connected to a Catalyst switch and grabbed an ip address (10.2.x.x subnet) no problem.  I can access the 5508 via https using the SP.  However, port 1 is connected to the same Catalyst switch, but on a different vlan (subnet 10.20.x.x).  Both ends show that the interfaces are up, I can ping the interface from any other host on the network, but when I try to manage the device via https I cannot connect.  We are using WCS and I cannot add the device from the WCS.  About all I can do is ping that interface.

Cisco Wireless :: WLC 5508 Management Interfaces For Wlans And Lag

Sep 3, 2012

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?

Cisco Wireless :: WLC 5508 7.3 Management Interface Access To GUI?

Jan 16, 2013

After I've upgraded software to the v7.3 and applied AP-SSO it made imposible to access the controller's gui via Service-port. So we tried to access it by management-port, but there is some problem too. It is not working from another subnets. But default gateway on management vlan is set correctly and I even tried to turn of all acl's on switch. WLC is only accessible from the same network. But at the same time wlc is replying on ping fine.All other protocols cannot connect to the controller.

Cisco :: 5508 Controller Setup - Management Interface

Jan 2, 2012

I'm trying to verify some behaviors I'm seeing with my 5508 controller setup, I've zero experience with this hardware and clueless on the best practices. With that said... out of the box I ran through the AutoInstall process.

I gave my service port an IP address on my subnet, vlan 100 and gave the management interface the ip address vlan 130
From my host I can ping the management interace and the interface gateway
I cannot connect to the controller via either through the web GUI or telnet
I can connect to the controller via both through the web interface and telnet
while connected to the service port, I can ping the management port IP but I cannot ping the gateway.
We have attached two test 3502I AP's and they found the controller and pulled correct ip addresses, clients can authenticate and access network resources as well as the Internet so for the most part, things are working but it concerns me that the management interface can't ping its own gateway.

Cisco Wireless :: 5508 / WLC Management Interface Not Bound To Port

May 6, 2013

I have 2 x 5508 Wireless Controllers, 1 mgmt port on each as standard. I noticied something different between these controllers running the same code.I can bound a physical port to the mgmt interface on one controller but not the other (both interfaces are untagged)see below, this config appears on one controller but not the other? Is this something to do with the initial setup? How can I add Phyiscal information to the other controller mgmt interface, I cannot delete the mgmt interface.

Cisco Wireless :: New 5508 DHCP For Management VLAN Not Working?

Sep 25, 2012

I have a new 5508 that I am setting up.  My first one from scratch.
managment -> ->dhcp
voice -> ->dhcp
guest -> ->dhcp
Local DHCP (via the 5508) is for the guest network while the management and voice use the Windows DHCP server.
My problem, Voice and guest work fine.  I have two SSID's (one 802.1X and the other PSK) that use the management interface that will not get an IP.  I have enabled  dhcp proxy from the cli on the controller.  I tried with the management VLAN tagged and untagged.

Cisco :: 2028 WLC Management Interface / Unexpected Traffic

Apr 16, 2012

I have a number of WLCs/WiSM2 running (still using WCS for management). The management interfaces for the controllers are on a purely private subnet. While going through the intenet edge ASA logs I noticed some traffic drops for the controllers on the Inside interface. I took a packet capture from the controllers and found that they were sending TCP traffic to a number of IP addresses (Microsoft, Hotmail and Google) - always with a src port 2028 (submitserver) with the ACK/FIN flags set. Why this traffic is coming from the management interfaces? The management interface is not used by any wireless clients and is not the default interface for any of the SSIDs.

Cisco Firewall :: Pass Management VLAN Traffic Through ASA 5510 In Transparent

Mar 10, 2013

We have a small cisco 1800 series workgroup router that seperates our network from the outside world.  The data coming into our network goes into the router on interface fa0/1 and comes out on interface fa0/0.  fa0/0 is split into 2 sub-interfaces (fa0/0.2 and 0/0.3).  These sub-interfaces correspond to a desktop and server vlan on our network.  The workgroup router is connected to a 3560G trunk port (we'll call it switch 1) and switch 1 connects to another 3560G (we'll call it switch 2). Recently I was asked to add another layer of security to our network by installing an ASA 5510 firewall and forcing certain types of traffic to authenticate using their domain credentials for our network.  The firewall was set up between the router and switch 1 in transparent, multi-context mode.  There are 2 security contexts, 1 for the desktop vlan and 1 for the server.  Both have the same security settings applied to them since we want the same behavior regardless of whether they are trying to access the servers or the workstations.

Cisco VPN :: Stops Forwarding Traffic On Subsequent Connections 861

Mar 23, 2011

I have a very strange problem on 2 (independent) Cisco 861 routers in different places.They are both configured as easyVPN servers. One uses UDP, the other TCP. VPN clients connect by using Cisco VPN client software. This cannot be changed because the customer expects it this way. Both routers have the same problem:

* the first VPN connection after a reset works fine. Traffic passes through and it is perfectly usable. I can ping the internal network interface on the router side from the client without problems.

* the second connection (and all subsequent ones from different client machines etc.) connects fine, no errors on the client whatsoever (not sure I evaluated all possible debug output on the "server" side). However,  no traffic passes through. Pings do not come back from the 861 anymore through the VPN tunnel.I already enabled ICMP debugging and saw that pings are actually answered by the 861, but do not reach the client.The same seems to happen to any and all other packets as well.

* If I restart the 861 the very same thing happens: first VPN connection works fine. You disconnect, try another connection from the very same client computer, and it does not work anymore until the next router reset.I append the configuration for sake of completeness. confidential parts are represented by XXX. Some ACLs are not in use right now; I used them for testing. [code]

Cisco Switching/Routing :: AP1242G Forwarding Traffic From One Subnet To Another

Feb 20, 2012

I’ve configured a small WLAN for a school that wants to have wireless network access for their staff as well as for guests doing presentations. They want the staff to have access to everything on the /24 network as well as the Internet. They want the guests to only have access to the Internet. I have attached a picture which shows how the network has been configured with 4 Cisco AP1242G AP’s attached to a Cisco SF302-08MP PoE switch and then to a Symantec Security Gateway to the Internet.
I can authenticate wirelessly to the STAFF SSID and ping anything on the /24 network and access the Internet.I can authenticate wirelessly to the GUEST SSID and ping anything on the /24 network, but not anything on the /24 network (which is what we want). However, when on the GUEST network you can’t access the Internet. I added a default route to the Cisco 302-08MP switch to (Symantec firewall) thinking that would forward the traffic from /24 to the Symantec firewall out to the Internet, but that isn’t working.How would I go about getting the traffic from /24 to hit the Symantec firewall and the Internet, without hitting anything else on /24? Do I need to put the Symantec firewall in a different subnet like /24? Am I missing anything else?I’ve worked with Extreme Networks & HP / 3Com CLI in the past, but never with Cisco and never with web based management

Port Forwarding Working For Incoming Traffic But Not Outgoing?

Feb 6, 2012

I have a licensing server. Other computers need to turn on a program, they send a message to the licensing server, and it responds that they have permission to run.Until today the licensing server was plugged into its own ethernet wall socket and configured with a static IP address. Today I put a router into that wall socket and now the server's plugged into the router.The router (WRT-54G) was set to the static IP - and now the internet on its network works. I set all ports to be forwarded to the server's internal IP address - and now my programs can detect and ping it. But now the server won't send back permissions to use licensed software, or even reply with a list of the software which it can license.

How does the traffic forwarding works in this case on the uplink ports? Do these uplink ports actively forward traffic or it is only the uplinks ports on Active that forward traffic? I see CDP neighbors on both Active and Hot SUPs uplinks ports - it  indicates that packets are flowing on both cards.
I want all uplink ports on both SUPs to actively forward traffic. Does it work? What is the config for this?

2. Can we also forward all traffic to the external web proxy to filter the websites that can be accessed (without configuring it on the browser)?

3. Can this be achieved using the L3 webauth?
Our topology:
WLC -- Switch -- ASA Firewall -- Internet -- External Web Proxy
We are using WLC as DHCP server for Guest WLAN with ASA Firewall as the gateway.
