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?

How to disable dhcp proxy on controller and what is the impact of doing it in the middle? We tried once by giving 'config dhcp proxy disable' command but seeing virtual ip again.(likely it gets back to proxy mode). We also have ip helper address on the L3 interface.

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 :: Migrate From WLC4404 To WLC5508?

Jan 7, 2013

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 Firewall :: ASA 5515-X - After Upgrade From 8.6 To 9.1 No Ping?

Apr 21, 2013

I've got a little problem with my ASA 5515-X after upgrade from version 8.6 to 9.1.
 
I've got two 5515-X in A/S-mode and upgraded both as described on cisco's website (first standby-unit, failover, etc.). Everything worked just fine except pinging the ASA-interfaces themselfes. Before upgrade it was possible to ping from any subnet to the internal interface, but now it's not. If I'm on the router next to the ASA I'm able to ping, but every ping from behind that router fails. The ICMP-packets get into the ASA (counter on ACL raises up), but no reply is getting into the source.
 
The configuration fir ICMP was not changed and says "permit 0.0.0.0 0.0.0.0" for any ICMP on the internal interface. The router betwenn my subnet and the ASA has no ACL installed and - as said above - the ICMP gets obviously to the ASA but doesn't come back!?

Cisco Firewall :: ASA5510 - Cannot Ping Inside Over VPN After Upgrade

Jan 16, 2012

We currently have a central hub using an ASA5510 and then a few site-to-site VPN connections to our support staff homes. The devices at the homes are Cisco routers. We were running version 8.25 on the ASA and all was working fine. We recently upgraded to version 8.42 and although all the functionality of the network is ok and it does what it should, our support staff cannot ping, ASDM or telnet to the ASA inside interface anymore whereas they could before the upgrade. The home VPNs all run on a 10.30 subnet (i.e. 10.30.1.x, 10.30.2.x etc etc). I can post our config (security edited of course), but it is quite a big config. The command management-access inside is specified and the 10.30.0.0/16 subnet is permitted to ASDM and Telnet. Are there any extra things that have to be done in version 8.42 to get this to work as the support staff do have to access the firewall for configuration purposes. At the moment, they have to telnet to one of the routers on the local LAN and then Telnet to the firewall from there.Prior to the upgrade, they were all able to ping the inside ASA interface and also telnet and HTTPS to it from their PCs at home. Now they cannot and the only change made was an upgrade to 8.42. Immediately after the upgrade none of them can ping the interface anymore and it seems it can only be accessed from the local LAN. I cannot find any access-lists that might be blocking the packets so can only assume it's something in the way 8.42 works.

Cisco Switching/Routing :: 3560G Can Ping Devices In Enterprise LAN But Cannot Ping Interface

Mar 31, 2012

I have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.

Cisco Switching/Routing :: Can Ping From R1 To R3 SVI4 Gateway But Cannot Ping Host

Dec 12, 2011

I set this up and I can ping all the gateways but never the hosts.  I was hoping I could make these links between 6500's a mix of L2 and L3.  Check it out.  They are connected in a linear fashion R1--->R2--->R3.  I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4.  I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration.  I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.

AAA/Identity/Nac :: CSACS-1121-UP-K9 - Possible To Upgrade It Being Non Upgrade Part

Sep 10, 2012

Is it possible to upgrade the CSACS-1121-UP-K9 to be a non upgrade part? We were going to upgrade from a Windows 4.x to the above Appliance (version 5.x) but there is now a reason to keep the old Windows version running therefore we cannot give the new Appliance the old ACS's licenses?!So we should have (with hindsight) bought a fresh version of the ACS 5.x rather than an upgrade.

Can't Ping XBox 360 But Can Ping Other Devices

Mar 1, 2013

I had both a Westell 7500 and a Linksys Router working fine and had my 360 setup as an extender for Windows Media Center so I could stream TV, Music, Movies, etc from my desktop to the 360. Then I switched my modem/router out with a Zyxel PH5001Z

So now today I noticed that I can no longer find my desktop through the XBox. I have adjusted my firewall settings on the modem itself, even completely disabling it. UPnP is enabled for the 360 and the device is showing under my device table. At first I wasn't able to ping any network devices but after creating an ICMPv4 Firewall rule it worked fine. I've confirmed the XBox IP Address through Network Map, the Device Table on the modem and through Network Settings on the XBox. I've diabled my modem firewall as well as Windows Firewall, completely and I still can't ping my XBox or set it up as an Extender.

I have the XBox connected wirelessly using WPA2-Personal and it's operating in 802.11g/n mode.

Cisco Wireless :: 2500 / Wireless Guest Users Cannot Ping If ACL Is Applied

Sep 16, 2012

This is the first time I am trying my hands on wireless gears. I have 2500 WLC and 1142 AP (which I converted from Standalone to LAP).I have a layer 3 POE switch where i am using port 1 for the WLC which is a trunk port.

Port 2 is for the AP using access vlan 111

Port 3 is trunk port going to a router where i am running dhcp server for the VLANs which are as follow:

VLAN 110 -Corp Wireless (10.1.110.0/24)
VLAN 111 - AP-Mgmt (10.1.111.0/24)
VLAN 999 - Guest (10.1.101.0/24)
 
I wanted to block the traffic from the Guest VLAN 999 but when i apply the ACL on the Guest Interface created on the WLC, I dont see any pings going across and neither I see any hit counts on the deny statement as if the ACL is never applied.

Cisco Wireless :: 2811 - Can't Ping Default Gateway

Jun 9, 2012

I'm trying to get a 2811 router with a NM-AIR-WLC6 Wireless Controller Module to work with an c1200 series access point. The LWAP is connected to a 2690 switch which has a trunk connected to the router. My configuration looks very similar to example 2 on this page: [URL] . The LWAP does get an IP from the DHCP pool on the router. I can also connect to the GUI of the controller from a PC on VLAN 250 (which also is connected to the switch).
 
[URL]
 
The moment I join my Wireless network I get no IP and when I enter a valid static IP, I still can't ping the gateway. I also noticed that the controller could ping the gateway before I configured the interface. After configuring an interface with that gateway, the controller loses the ability to ping to it. I can't seem to figure out why. I've been working all week on getting this controller and LWAP to broadcast a fully working network.

Cisco Wireless :: 1310 / Unable To Ping Across Bridge?

Jun 17, 2012

I have installed 2 Cisco 1310's, connecting two buildings that are about 1000 yards apart. One access point is connected to an existing 3560 24 port switch, the other access point has a new 3560 24 port switch connected to it. Also installed 4 1240 access point in the newly connected building to the new switch. Issue is my router and existing switches can not ping any devices on the other side of the bridge. They can ping both access points that make the bridge. I consoled the new switch and could ping the existing switches and router, after doing that the other switches and router are now able to ping the new switch. Now my main issue is I have a user using a 7921 phone connected to one of the new 1242's, when he makes a call to a person in the first building they can hear him, however he can not hear them. Our call manager is in another state were I am located. I can call him and vise versa, and we can hear each other. I have went over my configs server times, and doubled check my IOS versions to make sure they are up to date. I will be glad to provide configs upon request.
