Cisco Wireless :: 4402 - Data Path Down Control Path Up

May 5, 2010

have just set up a WLC 4402 as a Guest WLAN controller on the DMZ of our network. I have successfully managed to get our internal controllers to connect to it, with the exception of 1. it says the control path is up but the data path is down. the other 14 controllers worked fine, and in testing the last one was OK but it is now not working properly. the 2 controllers can ping each other but just won't create the data tunnel. there is a firewall in the middle but that has been set up to allow traffic between the 2 groups of controllers to be unrestricted.
 
the internal controllers are 4404's and all controllers are running the same version of code. 5.1.151.0.

Cisco Wireless :: 4400 - Guest Anchor / Foreign Controller Control Path Down?

Aug 16, 2012

We have a Cisco 4400 series wireless controller deployed as a Guest Anchor in a private DMZ.  We have 13 foreign controllers anchored to this for Guest Wireless.  We recently anchored 17 additional controllers to this Anchor controller. Since we have done that, periodically on just 3 of the foreign controllers, the control path shows down on the mobility peer, then comes back up.  We have had this issue in the past, but it resolved itself.  However, now we are seeing this issue again. Are we reaching a limit on EoIP tunnels?  I have read that there is a max of 71, and that is per controller, not SSID. We do have a firewall in the middle but all necessary ports are open.
 
We have had this issue for quite sometime, it just does not happen frequently.  Since we have added the additional controllers, it is now happpening very often, but only with 3 controllers.  There is not much in common with these 3 controllers.  2 are 4400 series, and 1 is a 5508.  All 3 are local on a campus LAN, different networks.  Could it have anything to do with memory or utilization?

Cisco :: 5508 Control And Data Path Down

Feb 6, 2012

I am trying to bring the mobility group between 5508 wlc (dmz) and internal 5508 wlc but it says control and data path down. (Ihave allowed port 97 and ports 16666-16667 both ways), should the ntp be sinked inline iwth other controllers ?,should the Mobility group need to match (already discussed this in another forum but experts suggested they never had to match the mobility group), should i first create the ssid and anchor - at the moment i havent created the ssid to anchor.

Cisco Wireless :: 2x WLC4404 After Upgrade Some APs Can Only Ping One WLC

Jan 9, 2012

i have 2x WLC4404 they are in the same mobilitygroup and worked since a long time. Three days ago, ill upgraded one of them from 6.0.199.4 to 6.0.202.0. I have nearly 90 APs (1231,1242, different models)
 
The upgrade was successfull and i moved the APs from WLCA (6.0.199.4) to WLCB (6.0.202.0) almost all APs worked fine without 6 of them. This 6 APs cannot ping the AP-Manager-Interface from WLCB. But they can Ping the Router in this vlan, WLCA-AP-Manager and all APs in this subnet. They only cant get to the AP-Manager-interface from WLCB. Ping to Managementinterface of WLCB is also ok. Management and AP Manager are in different subnets. All APs and the AP-Manager-Interfaces from WLCA+WLCB are in the same subnet.
 
Switchportconfig and routing are ok. ive resetet the APs to default, checked switchport config, resetet switchport, power down ap for a while. ive tried many things, but nothing worked.I ever only can ping AP-Manager from WLCA, but not WLCB (again same subnet, and about 80 other APs work fine)
If i install a new AP on the same switchport, it works fine, without any issues. when i than unplug the "newAP" from this switchport and again connect the "oldAP" it can ping WLCA+WLCB and anything is fine.
 
Now i have the next and bigger problem nearly 15 of the APs that worked fine after upgrading, for now 3days+. Now they cannot ping the WLCB-AP-Manager-int too. And they dont failover to the WLCA with (6.0.199.4), i can reboot but they ever try to connect to WLCB. But they know both controllers.I only can get them to WLCA via ssh: capwap ap primary-base WLCAsname WLCAsmanagementIP..why the APs dont fail over if they dont reach WLCBsAP-Managerinterface?why i cannot ping WLCBs AP-Mana-Int from some APs.

Cisco Wireless :: Configure 802.11n On WLC4404 Or WLC5508 In 2.4Ghz?

Aug 15, 2012

how to set up support 802.11n on WLC4404 or WLC5508 in the 2.4Ghz? WLC4404 supports 802.11n? or support this protocol only in the brochures? I spent a few days, but did not get the result. I'm connected at speeds 65/130Mbit, but the real speed tests never exceeded 45Mbit. The AP from the test laptop is 7-10 meters.I tested the laptops with a Linksys AP E1200-EE ( 40Mhz, FastEthernet uplink port...)and received nearly 100Mbit!
 
At WLC5508 able to connect at speeds 150/300Mbit/c but only in the 5GHz band, but real speed tests never exceeded 70Mbit.In 2.4Ghz range I connected at speeds of 130/144Mbit/c, but actual measurements showed no more than the 45Mbit.
 
All tested with iperf and with site speedtest.net.
iperf -w64K -s
iperf -w64K -i 2 -t 300 -c x.x.x.x
 
Laptops: Asus (Atheros AR9002WB-1NG) and Sony (Advanced-N 6230).
 
My tests AP: 3501I-E and 1252AG-A
SW on WLC5508 7.2.110.0
 
AP tested in different variants - open system and WPA2+AES.

Cisco Wireless :: 1262 AP Doesn't Register With WLC4404

Oct 15, 2012

We currently have about 50 Cisco 1252 wireless access points running from a 4404 Wireless LAN controller.  We need to order more APs, but of course the 1252s have been discontinued.Was assured by Cisco that the 1262 would work just fine with our WLC.  I'm messing around with a trial 1262 and am running into problems.We hard-code the IP address, hostname, default gateway, and controller IP address in each of our access points.  I did that with the new 1262 the same way I did with the 1252s:lwapp ap ip address lwapp ap ip default-gateway etc., etc.That didn't work.  Then I tried doing the same thing using (not sure if this is the correct terminology...) the capwap commands.

The AP still doesn't show up on the WLC's GUI, though I can ping the AP from the WLC and I can ping the WLC from the AP.I also can't use a web browser to get into the access point's configuration tool.  Do I understand correctly that the lightweight APs don't have the GUI?

Cisco Switching/Routing :: WS-C3524-XL-EN HP Flaps Up And Down / Disconnects / Reconnects Continuously

Mar 2, 2009

latest OS release for this Model number: WS-C3524-XL-EN switch.  I currently am running Version 12.0(5)WC17
 
The reason is, I'm having some issues installing some HP PC's connected to this switch.  The nic card on the HP flaps up and down, disconnects/ reconnects continuously.  The only way I get it to stop is to bring down the speed on NIC or the switch port to 10mbs. 
 
If I add a nic card and disable the system board nic all is well.The HP rep says that Cisco has a patch for this unit. Any recent patch or what the latest OS is for this switch?

Cisco :: Migrate From WLC4404 To WLC5508?

how to migrate from WLC4404 to WLC5508. I want to know your propositions.
 
I could replicate the configuration manually but there is a lot of confirugation menus and all. If both could be online and migrate the AP to the new one until there is none on the old one, it would be great.

Cisco :: 3501E Not Integrating In WLC4404 With 1121 And 1241 APs

Nov 11, 2012

We have a WLC 4404 with about 85 1121 and 1241 APs. -  I just added 6 new 3501E with Antennas, and configured the a new SSID, but non of my clients can connect to any of the 3501s.   One solution from a tech was to update the NIC drivers.   I verified that all test clients are 802.11N and sometimes they find the 3501 but often they switch to another of the older and weaker 1121 or 1241s.   On one test I had a 3501 just outside his room and his client nic was picking up a weak signal 2 floors up, then it would go to one 1 floor down.  eventually we could get it to feed of the nearest 3501 but it would go back to another 1121 or 1241 soon thereafter,.

Cisco Wireless :: 5508 Mobility Groups

1) Is it possible for 2 WLCs installed in seperate data centres with L3 seperation to be joined in a mobility group? We will have aps in the branch offices split between controllers so we want to make sure roaming work ok. Also all guest access should be anchored to data centre 2.
 
2) in flexconnect local switching mode, do I need to create flexconnect groups if I'm only using radius servers in the data centre with no requirement to use local radius as a backup?

Cisco Wireless :: 5508 - Mobility / Roaming And Web Authentication?

Nov 27, 2011

I have two 5508, no anchor, only one SSID with internal web authentication using radius server.Under "Configuring Mobility Groups", Cisco guide says: "If a client roams in web authentication state, the client is considered as a new client on another controller instead of considering it as a mobile client".
 
I understand that if a client that has already autheticated via web roams between two LAPs that are associated with different WLCs, it has to reathenticate.

Cisco Wireless :: Mobility Group Between Controller 4400 And Virtual WLC

Mar 7, 2013

I read the configuration guide about the 7.3 release. And I figured out that you will need a hash key for establishing a mobility group relation between a controller and a virtual controller. The 7.3 release for the 5500 series works fine for me.But the latest release 7.0.235.0 for the wireless lan controller series 4400 does not have a functionality to add a hash key while creating a new mobility group member.The command "config mobility group member hash" is totally missing.

Cisco Wireless :: 5508 - Mobility Ping And SSH Errors After Upgrade To 7.2.110.0

Aug 7, 2012

After upgrading my 5508s to 7.2.110.0, they are reporting mobility data path errors to one of my WiSMs running 7.0.235.0.
 
I get these messages on the 5508s reporting that it can't send a ping to the affected WiSM:
 
*ethoipSocketTask: Aug 08 21:15:41.175: %ETHOIP-3-PKT_RECV_ERROR: ethoip.c:341 ethoipSocketTask: ethoipRecvPkt returned error
*ethoipSocketTask: Aug 08 21:15:41.175: %ETHOIP-3-PING_RESPONSE_TX_FAILED: ethoip_ping.c:312 Failed to tx a ping response to <ip address>, rc=5
 
But maybe there is another clue because I also see in the same log these errors referencing the same WiSM:
 
*bcastReceiveTask: Aug 08 21:15:45.310: %LOG-1-Q_IND: mm_dir.c:1969 Failed to recreate the SSH Rule for <ip address>.
*mmSSHPeerRegister: Aug 08 21:15:44.829: %MM-1-SSHRULE_CREATE_FAILED: mm_dir.c:1969 Failed to recreate the SSH Rule for <ip address>.
 
Why is the controller trying to SSH to another controller?  Was some SSH related feature added to 7.2 that has been accidentally enabled?

Cisco Wireless :: Migrating 2 Standalone 5508 To One Mobility-group

Jan 23, 2012

for some reason our wlan-controllers were build up to be standalone instead of beeing one mobility-group. I would like to change this in order to use all features of HA.
 
let me describe our scenario: two WLCs 5508 running SW ver. 6

- same subnet

- both are running in master controller mode

- different hostnames, ip-addresses, etc

- all settings for WLANs and AP-groups (exept the APs themselves in these groups) are the same

- in total at this moment we are running around 100 LAPs configured one half on WLC#1, the other half on WLC#2
 
I don't know exactly why, but when that setting was installed, someone already configuredHA for each accesspoint... e.g.:

- AP#1 primary WLC#1, secondary WLC#2

- AP#2 primary WLC#2, secondary WLC#1 but without WLC#2 knowing the configuration for AP#1 it makes no sense, correct?
 
so my question is: how should I do the migration in the best way?
is it easy as:

- disabling master controller mode on WLC#2

- configuring both WLCs into one mobility group

--> WLCs are negotiating their configurations for the APs

Cisco Wireless :: 602OEAP / Mobility Anchor And Remote Wired LAN?

Mar 10, 2013

deploying a DMZ wireless controller and I have a question regarding remote wired LANs. My 602OEAP APs support 1 or 2 of their LAN ports as being accessible across the DTLS tunnel.This works fine when they register across internet right to my internal WLC. However, now that I'm implementing a DMZ controller for this purpose, how will this work? I dont see the option for the Remote Wired LAN to be linked to a mobility anchor.Some of my users have printers connected to the LAN port on their 602OEAP and I need to maintain this functionality once I move their APs to the DMZ controller.

Software versions: 7.4.100.0
DMZ Controller: 2504
INT Controller: 5508
