We have a Cisco 4400 controller and a mix of 1010 and 1131 access points.
We have been running out of IP's on our DHCP server because the apple devices are not releasing there IP's.
Have a WLC 5508 running 7.0.230 with internal DHCP server. Timeout is 3600 seconds. The IP addresses never seem to be released. The controller will show 70 clients but 254 addresses will be assigned.
View 2 Replies View RelatedRouter is setup as DHCP and only allows 7 IP address leases that expire daily. Lease time is set to 0. I have the latest firmware. Until recently when our family started using Apple iPhones (2 of them), I didn't have this issue.
Now I'm having a problem where my clients table will show leased IP's with no devices attached to them. I have to clear those no-name addresses so that the iPhones and other non-Apple wireless devices in the house can re-establish a connection.
How can I get those IP's to be removed without having to constantly log into the router and clear them?
how to setup the wireless interface to forward multicast packets? Basically I cant get the ipads etc.. to see the AppleTV to control it. I connected an AP and it works fine so its got to be something with the way the router handles the packets from teh integrated wireless interface. I've been searching the forum for about 1hr and haven't founf anything other than a breif mention of broadcast forwarding and multicast setup.

We have found a known bug:
CSCty90928
LMS Pari jobs are not releasing SSH,telnet connections of the devices
Symptom:
Telnet/SSH connections are not released by LMS
Conditions:
Pari collections jobs are not releasing the connections after the Job completed
Workaround:
None
This bug is categorized as "2 – severe" and is in "Open (Postponed)" status.I have a few questions:
1.) What is the ETA to fix this bug?
2.) Are there any other known bugs matching what we see (documented public bugs, with bug ID's, internal bugs or even undocumented bugs).
3.) Is there any released or unreleased (even yet to be tested by TAC) patch we can use that should fix the issue?
4.) Is there any way to adjust LMS idle timeout of SSH/Telnet sessions (I couldn't find it in the GUI, but maybe there is a way to change this parameter using a perl script or modifying one of LMS properties files)?
Briefly here is my setup Internet is supplied to my building by ISP(I have no router) => apple time capsule connected by Ethernet.I have used WIFI to connect all of my devices in the past with no problem until i moved into this place. I have 2 macbooks that can connect without any issues Every single other device in the house cannot connect and does not receive a proper IP Address. The ones being assigned are in the 169.xxxxxx range. Even if i plug my Imac (which cant connect) directly in from the wall via ethernet, it wont connect.The time capsule is setup as a bridge with DCHP set to run automatically. I have reset everything numerous times and restored the router to no avail.I called the ISP and they said it wasnt their problem. I was under the impression they werent assigning the IP Address correctly or something.
View 1 Replies View RelatedI'm seeing a problem with Apple IOS devices connecting from one SSID and then connecting immediately to another. I've tried to replicate this fault with non Apple IOS devices, but I'm unable.
Environment:
Single 5508 WLC running 7.2.110.0 AIR-LAP1142N-A-K9 AP's
WLC is in clients head office, MPLS to their branch sites. AP's are in Flex Connect mode, with AP and Flex Connect groups for the AP's at the branch. 3 x SSIDs; Corporate (802.1X), Guest (Web-Auth) & Non-Corp (PSK).
Scenario:
Client is connected to the Corporate SSID with his iPad (new model, running iOS 5.1.1). No problem with access, he is able to roam throughout the building with good SNR/RSSI. He wants to test the other SSID's, he attempts to connect directly to the Guest or Non-Corp and gets an error message on the client saying 'Unable to Connect' or 'Unable to Join'. Debugs on the WLC for the client shows no connection attempt, no errors. I can see the client disconnect from the Corporate SSID, but nothing for the Guest or Non-Corp SSID.
If the client then disconnects and forgets the Corporate SSID from the wireless profiles on their i Pad, waits 20-30 seconds (I can see the client disconnect cleanly from the WLC) and then attempts to connect to the Guest or Non-Corp SSID's - he doesn't have a problem. He immediately associates, and is able to connect. If he then tries to connect directly to another SSID, while still associated to another from the same WLC/AP – he gets the error again. Forget/wait 20-30 seconds, attempt to connect – no problem. We've tested with several i Phones (4 & 4S), i Pads (2 & new model) - all running the same Apple IOS (5.1.1).
I unfortunately can't do much troubleshooting with TAC on this as the client is no longer onsite, and I don't have a 5508 in our lab that I can currently test with. I've tried playing with beacon intervals, etc to no avail.
On my wireless network, I am running guest access that I want to have as authenticated. If I enable WLAN, security, layer 3 web policy, when an iPAD / iPhone connects, they get directed to the Web Auth splash page, on where they must enter username & password. My users do not want to be directed to this page everytime they login - just select the SSID and connect - is there a way of authenticating guests via a WLC4400 without going through the splash page everytime?
View 6 Replies View RelatedI have recently deployed a wireless network using a WLC 2504 with 21 Light APs. All seems fine except that Apple Devices drop their connections every 15 minutes or so. A couple of minutes later they can reconnect but obviously something is wrong.
View 2 Replies View RelatedIn the company we have two SSIDs for corporate and guest networks respectively when I try to connect to any of the SSIDs it doesn't happen until 5 retries. The only log I get that seems to be related to it is the following:
*Jun 11 11:48:09.062: %APF-1-DISCONECT_MOBILE_DUE_TO_WLAN_SW: apf_policy.c:541 Disconnecting mobile 00:23:32:73:d7:15 due to switch of WLANs from 1(femsawl) to 2(visitas)
Here it shows a switch between SSIDs but if you just turned on an apple device and try to associate for the first time to any of the SSIDs the scenario is the same, several tries to connect.I am running a 4402 wlc with 6.0.202.0 software version.
I have two Cisco 1200AP.
I have it configured with two SSIDs, one corporate (802.1x) one using WPA2 Personal.
I have no issues on the corporate, but I have found that Apple devices appear to detect it as a WPA2 Enterprise, and request a username and password.
If I enter the network manualy as WPA2Personal the devices joins the network ok. Then ocasionaly the device looses its link to the network and fails to pass traffic.

we are running 1140's and 1130's in autonymous mode and seeing a TON of requests for passwords on IOS devices where we have an open network.

All other non IOS devices do connect, and most IOS devices connect after a considerable amount of time.
I recently upgraded my Linksys wrt120n router firmware & had to reconfigure settings. Subsequently, some (but not all) of my apple devices are having intermittent wireless connection problems. Specifically, my ipad1 & ipad2 never lose their connection but a mac book pro (~ 2 years old), iPhone 3g, iPhone 4, older iPod touch & very old i book g4 all work for a period of time (usually 1/2 day) & then lose their connection. When I attempt to reconnect these devices I receive the following error..."unable to join the network xxxxxx....". I also have a Dell laptop (1 1/2 yrs old) that generally does not have the connection problem. Finally, when the devices do lose their network connection all I have to do to reconnect is go to the Linkys router setup webpage & click on save & the wireless connection works again (almost like this is just refreshing the connection for these specific apple devices). I was not having any problem prior to the firmware upgrade & from what I have read the older firmware version is no longer available so going back to the old firmware does not appear to be an option.
View 1 Replies View RelatedI am setting up a new Guest network with a captive portal and it seems to all work fine except when Apple devices go to sleep. When they come back on it isn't just a case of logging in again as it just indicates to the client that it is still connected and won't present the login page again. The Controller will show the client as auth required. So far the quickest way has been for me to delete the network on iPads and re-enter my settings or create a new profile on a Macbook and join again. I have also had some success when doing a manual DHCP refresh on my Macbook which sometimes seems to kick the Controller into action so it presents the login page to the client again. Whether it is related to the timers on the Controller (5508 running code 7.0.235.3) or - as I just read in another post by Leo - the 20 minute timeout that all Apple devices have built in to conserve battery life
View 3 Replies View RelatedI have two WAP4410N devices on my network.When I try to connect with a wireless device (iPad, Smartphone, etc...) it does not connect.However, if I assing that device a static IP, it connects.Here is the setup:
-2 WAP4410Ns that have static IP's assigned to them. They plug into my 3560's
-Three Cisco Catylist 3560, one of which is my Default Gateway.
-Windows 2008 Server R2 (Domain Controller, DHCP, DNS)
On the System Summary screen in the Port Statistics table when you click on one of the Connected links the pop open window does not show the IP address of the connected device when using IPv4. Where can I find this?
If the devices are using static IP addresses and not getting them from the DHCP server they do not show in the Client Table under DHCP Status.
If they are know MAC addreses because they have been assigned to static IPs on the DHCP setup screen they will not show up in the Uknown MAC Addresses pop up window.

A customer of ours has the following access points and wireless lan controllers on site. They want to use the Apple Bonjour service with Apple TV's and iPads. I have enabled multicast feature of the 5508 globally and one the SSID.The Apple TV has an ethernet connection and the iPads connect over the wifi. The Apple tv is on the same subnet as the iPad's - the Bonjour features do work for approx 5/10 minutes then it stops working for some reason. The Access Points plug into a Cisco 2960 Layer 2 switch, the 5508 controllers plug are in LAG mode and plug into a Nortel Layer 3 stack which I have enabled IGMP snooping.I've read that the Apple Bonjour service isnt designed to work on a multi subnet network - but both the Apple TV and iPad are connected on the same subnet. Sounds like some kind of timeout but not too sure.

OS: Windows Vista Home Premium?Trying unsuccessfully so far to reconnect a client machine to a wireless network that it has been on for a year or so.ISP was down for about 2 hours the other day and when it came back up, the client machine started getting the IP address conflict. Went in to release and renew and got the following error messages:
on release: An error occurred while releasing interface Wireless Network Connection: An address has not yet been associated with the network endpoint.
on renew: The DHCP client has obtained an IP address that is use on the network. The local interface will be disabled until the DHCP client can obtain a new address.
The next thing I tried was to go in an give a manual IP address to the Wireless Adapter. But the TCP/IP properties are greyed out and I receive the following error message:Some of the controls on this property sheet are already open. To use these controls, close all these property sheets and then reopen this one.
In setup for old RV042 (V1), when updating / adding Mac addresses, the table is always sorted by IP addresses. But in the new oneRV042 (V3) I have, even with latest firmware 4.2.1.02 the list is random, thereby increasing the chance of user entering DUPLICATE IP addr with diff Mac addr. That will result in conflict.If the firmware sorts the DHCP entries by ip addresses, user would be able to catch duplicate ip errors even if the system does not flag the errors. All Cisco smart engineers can you all get the dhcp entries SORT by ip addresses.
View 2 Replies View RelatedCurrently my home network is being switched via TrendNet TEGs80G unmanaged gig switches. I have been using them for about a year now with no issues. As my home network becomes more advanced, I recently just added a Cisco ASA5505, I am thinking about swapping those unmanaged devices, 4 of them, to managed. I was looking at the Cisco SG300-10 for upstairs, and a 16 port variant for my main core. These devices do not support full Cisco IOS cli, but they are manageable with a rich feature set nonetheless. My question is, should I swap the unmanaged devices with the more expensive Cisco devices, or just keep what works and save the money until I really need to spend it. As previously stated, my home LAN works just fine as it is, however my WiFi, NTV550s, server and workstations are all on the same network. Probably not the most secure but it is what it is without VLAN support.

We have a pair of 4500s set up as HRSP pair. We have many VLANs set up. In one of the VLANs is a working Red Hat cluster which uses multicast for its heartbeats. The VLAN interface on each switch has ip pim sparse-dense-mode enabled on it. Multicast routing is not enabled.We now need to be able to send multicasts across a few VLAN to allow apple TV to work with our WLC and lightweight access points.
I assume I can just turn on multicast routing and enable ip pim sparse-dense-mode on the VLANs I need.Is this the case and will it have any effect on my current multicast traffic?
