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 :: 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 :: 4404 Guest Anchor Controller With 5508 Foreign Controller?

Aug 12, 2012

I know that the 3600 series APs are not supported on the 4404 WLC.  However, would the following scenario be supported? 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.

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 :: AIR-CAP2602I-E-K9 Configure SNMP From WLC 5508?

Jun 11, 2013

How are certain settings/config transfered across to the AP's from the WLC, e.g. username and passwords, snmp strings etc.... I assume this is when the AP joins the WLC.More to the topic of the original question I had in mind, is it possible and if so, how? - to configure snmp read and write string from the WLC and push this config out to AP's. I can't believe someone will have to sit down (me) and SSH to 150+ AP's per WLC to configure SNMP.
One of the buildings lost connectivity to the WLC's breifly a couple of days ago and all seemed to have lost their SNMP settings. Connectivity was restored, but couldnt poll the APs. When I SSH'd on to a couple of AP's, and manually configured the snmp-server community xxxx ro - SNMP started working again. Since there are many, there must be an easier way of doing it.I've tried resetting the AP from the WLC and also powering down AP's and bringing them back up.
Using WLC 5508 on 7.4.100
Using AP's 2602 on IOS 15.2(2)JB$

Cisco Wireless :: Losing The 5508 Snmp Packet?

May 16, 2013

We had a system outage due to power problems a few days ago, and now our WLC is showing short term packet loss when monitoring it using SNMP.  We also monitor it using ICMP, but that shows no packet loss.  I looked at the interface statistics on the WLC and all of the switches in between and there are no errors to be seen.  is there any way to troubleshoot this problem on the WLC?  I am more familiar with IOS than the WLC CLI.

I am working on a wlc 5508 in a lab environment doing snmp reporting & i was wondering if there is anyway to after the timing on how quick the snmp traps appear on the trap log page? I have looked through the gui but cant seem to find anything, so not too sure if there is a cli command, the traps come in very quickly on the nms way before they appear on the trap log page.

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 :: 4402 WLC Management / Local Controller Versus Cloud

Feb 26, 2013

We are currently looking to upgrade (re-design) our wireless network at our college. Any experience going from a local, controller-based wireless network to a cloud-based controller? If so, what have you found the pros and cons to be?
If you thought about going to a “cloud solution”, what stopped you?
We are currently running wireless at our 3 primary campus locations, and looking to add it to our 3 satellite locations. We use 4402 WLCs at our primary locations with a mix of 1140 and 1240 APs.

Cisco :: Catalyst 2960G / Get SNMP Management Working Over IPv6?

Jul 20, 2011

I recently picked up a Catalyst 2960G and am trying to get SNMP management working over IPv6.  I have the IP Address set to the local link, and can successfully ping and telnet to the switch (so the network can get traffic to and from the switch).  However, SNMP packets just seem to disappear.  I am running WireShark on my machine, and I see the packets go out to the proper IP, but nothing comes back.  When I check "sho ipv6 traffic", I can see where there are UDP packets that are received, but, again, none going out.  Also, when I run "sho snmp", all of the packet counts are 0.
Here are some relavant snipets from my "sho run":

interface Vlan1
no ip address
no ip route-cache

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?

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 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 Wireless :: 5508 / AP On Different Vlan Than Controller?

Sep 30, 2011

I have a 5508 controller at our headquarters and am installing some 3502 AP's at a remote branch.  Unfortunatly, the remote branch has a different Vlan setup for some reason and the vlan that is used for the WLC (90) is designated for telephony at this branch.  Can I put the AP's on a different VLAN (10) without having any issues?  I will still use DHCP option 43 to point them back to the controller. Below are the configs for the WLC interfaces and what I am proposing for the AP interfaces:
WLC Config
interface GigabitEthernet1/1/38
description WLC01
switchport trunk encapsulation dot1q
switchport trunk native vlan 90
switchport trunk allowed vlan 1,10,50,90,91,390,410-413,610-613,800,810,811

Cisco Wireless :: WLC 5508 / Rejoin To Different Controller

I use WLC 5508 (ver with aironet 1140. I need to connect my APs to different controller .After log in via ssh to AP i am trying to do:
capwap ap controller ip add x.x.x.x
But after reload, AP is still joined to the old WLC. So another idea was to log to that WLC and put:
config ap primary-base WLC2 AP_NAME x.x.x.x
and after that:
config ap reset AP_NAME
But still nothing, it's joined to another controller although "show ap client config" shows that primary-base switch is x.x.x.x ?How can i force it to join to other controller?

Cisco Wireless :: 5508 Anchor Controller In DMZ

Nov 26, 2012

We 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 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 IP address. The WLC seems to update its ARP table because if I run the command "show arp switch" it has the 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 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 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.

Cisco :: Getting 5508 Wireless Controller Configuration

Sep 15, 2011

So 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.

Cisco Wireless :: 5508 - LAP And Mesh AP With Controller Concepts

Jan 29, 2013

I have one controller 5508 that will hold 50 LAP 1262 and another Controller that will hold another 50 outdoor mesh access point 1552. Both controllers (not redundant) are at the HQ while the access points are distributed between HQ and 3 branches.
The requirements is to have the SAME 4 SSIDs on MESH and LAP each have a security type (, wep,wpa,dot1x...) on HQ and Branches. Now, in the HQ I don't think I will face a problem since the WLCs is on the same LAN, so 5 interface v lans will be configured one for the WLCs and access point and another 4 interface v lans for the 4 SSIDs.
Now, for the remote sites I need to create another vlan on the switch with DHCP and option 43 ..... for the access point to register with the controller.
But here, do I have to create another 4 interface v lans (4 different sub nets) that should be bidden to the SSID as in the HQ?

Or the Access point will encapsulate all the traffic including the client traffic? Note that I have outdoor mesh access point and Lightweight access point and the BW link between the HQ and branch is 100M.
Also Can I have roaming between the same SSID that broadcasted on MESH and LAP knowing that each have different controller.
