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.
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.
I have 2 controllers as below one with 6.0 version and other with 5.2 version AIR-WLC4404-100-K9 6.0.202.0 AIR-WLC4402-12-K9 5.2.178.0 GUEST..Control path between controller flaps.All mobility anchors on wlan index 7 are down.All mobility anchors on wlan index 3 are down.Control path to mobility member x.x.x.x is down.No problem observed when i have software 5.2.178.0 on both the controller.
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?
We are planning to upgrade our controller 5508 from 7.0.116.0 to 7.1.91.0. Is this directly possible or i have to put some other image before directly upgrading it?
I have downloaded the firmware update "Ver.1.0.02 build 11" for my WRT400N from linksys.com several times. I then try to update my firmware on my router. Each time I try, I get an error message that says "Incorrect file path."
I thought I would leave a message on a problem. I did two chats to the support desk and this was not brought up and it is obvious. I just installed the 4200v2 as a replacement for a NetGear. I bought for the n performance and the USB for a shared disk/media file server. I connected a640G Western Digital My Book to the USB. I was able to see the drive in the asp interface of the router, but I kept getting the "error code: 0x80070035 network path not found" message. My computer is a 6 month old HP with Windows 7 running Bitdefender Internet. I found I could get to the drive from my wife's Toshiba (only used for browsing, so minimal security), so I thought it was a firewall issue (also what Cisco said). After doing some Internet mining, I found that the issue is the Netbios setting in IPv4. My PC had the setting Default, which requires the DHCP server to provide the setting and apparently this was not set by the 4200. Without Netbios the disk cannot be mapped. Changing this to NetBios "enabled" solved the problem. This can be reached by going into the Control panel:Network and Sharing Center. Click on the connection (either local area or wireless), then open the properties, click on the TCPv4, Click properties, then advanced. Go to the Win tab and select Netbios enabled.
Here is the current logical routing path of the network I've inherited:ISP_ASA_1800 --- P2P link_ LAN, However, the equipment is setup up in this inefficient physical topology: Internet_ASA_LAN switch --- 1800 --- P2P link_LAN, The 1800 is the default gateway for all LAN hosts. This means that all traffic not destined for the LAN goes first to the 1800 which has routes for the Internet and for the P2P. If traffic is destined for the P2P, this is no problem. If traffic is destined for the internet, then in my opinion this is an inefficient routing path because the traffic ends up doing this:LAN host > switch > 1800 > back to the same switch > ASA > Internet, So I am thinking of setting up the physical topology to match the logical topology like this:Internet, ASA_1800 ---- P2P link_LAN switch_LAN hosts This means I will connect the 1800 and ASA directly to one another. Am I on the right track? Is this the best way?
I finally can upgrade my 1841 routes from 12.4 to the latest 15.1 IOS. Any info about upgrade path , do I need to modify config file and provide me with upgrade instruction link or something like that ?
I have a problem with the return path of NAT'd traffic on a Cisco 877W router. Here's the network setup:
gatekeeper1 (192.168.0.1) is a Cisco 857gatekeeper2 (192.168.0.253) is a Cisco 857gatekeeper3 (192.168.0.251) is a Cisco 877W The default route is 192.168.0.1 on all devices, however there are some static route defined so that traffic to certain IP addresses bounce off to 192.168.0.253 and use that Internet connection instead. This new connection is designed so that traffic aimed for a certain internal IP address (192.168.0.190) comes via this third internet connection in order to take the load off of the main line. NAT is all configured and appears to be working when .251 is the default route but as soon as I set it back to .1, the traffic appears to come in but doesn't go out again.
Where can I find information regarding the details and upgrade path for the 2821 Intergrated services router. We are looking to upgrade from 12.4 (c2800nmc-spservicesk9-mz.12.4xxx.bin) to 15.1. Is their a spefici location to look for in the download or IOS area for upgrade paths?
I recently bought my book live 3TB everything works well with it, I can stream movies upload them, remote access and much more with a good speed, the problem is when I direct connect my book live to my PC via Ethernet, windows can't find the path of the drive. However, I tried to direct connect via Macbook and it works with no problem.I tried to fast reset my book live to factory default settings and direct connect from my book live to my PC via Ethernet, simply it worked! But then it stopped working for some unknown reason.Its a pain when i need to transfer large files via wireless.
Recently I've changed my all local I.P. series in the server from 192.168..to 10.219..& the server 2008 providing through DHCP.So, I've to re mapped the share folder to change the path in every system.But few files in 1 PC are still keeps the old share folder path when trying to open & failing or taking long time! NOT all files in that machine
I'm a network admin for a medium-sized (500-700 people) multi-site business and I have a simple question. Is there any utility or method I can use to identify the physical path a packet of data takes from a workstation on the LAN to a server on the same LAN?
For example, if I send a tracert command at google.com, I can see every router the packet touches before it gets to Google's router. Is there a method I can use to determine a similar path with switches in my internal network? If I use tracert or pathping, I only get a single hop since the workstations are on the same LAN as the servers even though I know there are two physical switches between them.
Basically, I want to send packets from a group of workstations behind a couple switches to a server and see if the packets are being lost in the switch somewhere to identify if there is a failing switch or something causing network slowdowns. map out the network more accurately so it would be useful to know.
i have 9 pcs on a lan. when i attempt to view the workgrp i get a message that indicates the the workgrp is not accessible and network path not found. i have tuned off windows and mcafee firewalls so that the only firewall functioning is with the modem/router(netopia) if i change the workgrp to the default(mshome) i can see the pcs.
I have a wireless network of PC, Acer Extensa laptop (laptop1), and Acer Aspire notebook (laptop2) which connect wirelessly to a Livebox. All machines are running XP (SP3). Laptop2 connects to the Livebox via a Broadcom 802.11g adapter.There is no problem with any of these accessing the internet. Until recently (not sure how long ago) there was no problem with any of them accessing each other.Yesterday we discovered that laptop2 has lost contact with PC. All other connections are fine (including PC to laptop2). I have checked evrything I can think of and have carried out a System Restore taking the machine back as far as I can but that has made no differenceLaptop2 appears to recognise the workgroup in its 'preferred networks' box but the PC does not appear in its list of computers on the network and any attempt to access the network (My Network Places>Entire Network>Microsoft Windows Network & click on MSHOME) results in "you do not have permission ..." then followed by "Windows cannot find the network path.."
I have attached my home network configuration. Only one part is not working. When the David-PC (win 7) tries to access the SharpeLaptop (XP) i get error code 0x80070035; NETWORK PATH NOT FOUND. This fails on wireless or ethernet hookup. All PC's are using McAfee Virus software which is supplied with ATT U-verse service. Trying to access the the daves-dell PC (XP) works fine Either of the 2 XP PC's can access the David-PC OK. The only failure is trying to access the laptop from the David-PC.If I disable the McAfee firewall on the laptop, then the David-PC can access the laptop. I have tried duplicating all the McAfee settings of the two XP P
I have one questions regarding if C6509 suports "ip tcp path-mtu-discovery" ? apply this command to GRE interface on C6509? if yes, let me know what is the the IOS for that.
I multi homed to dual ISPs using a single 6509e. Currently, I am only receiving a default from wash ISP and marking one with a higher local pref. most of my traffic flow is inbound, so this config meets my need. The issue I have: if either ISP has has an outage upstream from my directly connected peer, my router does not detect that and continues to send traffic out thru that provider only to be black holed. My 6509 will only support 256k routes, so full route tables isn't an option. I could receive partials from each ISP. Is there any other method to detecting this upstream ISP issue and then adjusting my local pref on my default to use the alternate provider path?
ASA running 8.2(5).When I enable ip spoofing on my network interfaces I see this getting logged:
Deny UDP reverse path check from 10.100.100.102 to 10.100.100.255 on interface SPECTRA-LAN
This is because interface SPECTRA-LAN (VLAN50) is the interface connected to the network with ip 10.100.100.0/24 but the interface do not have a ip address so it does not exist in the routing table I believe?However interface INTERN do also belong to network 10.100.100.0/24 which also is the management interface and the default route for hosts in network 10.100.100.0/24, but has no vlan.
1. move the management0/0 to SPECTRA-LAN and give SPECTRA-LAN ip 10.100.100.1?
2. give SPECTRA-LAN a ip address in the 10.100.100.0 range?
My routing table and interface list is:
Current available interface(s): DATA-BACKUP Name of interface Redundant1.10 DMZ Name of interface Redundant1.900 GUEST Name of interface Redundant1.990 HOSTING Name of interface Redundant1.100 Infrastruktur Name of interface Redundant1.20

I have always connected to other computers in my network, including my file server, and all of a sudden, it will not work. This is only happening on one computer. You can connect fine on all the others. I am running Windows 7 SP1, and in the network window, I can see the computers, but when I click on them to connect, it says "The network path was not found". If I access them via their IP in windows explorer, then I can access them . I have never seen this before. I attempted to disable Norton, I even un-installed it, and it still does the same thing.
I've Cisco7609-S with IOS 12.2(33)SRC2 met an issue is that "show ip route x.x.x.x" and "show ip cef x.x.x.x" shown next-hop is not actual switched next-hop.
For example, "show ip route 192.168.1.1" and "show ip cef 192.168.1.1" shown correct next-hop is 10.1.1.1, but the traffic destine to 192.168.1.1 actually not through 10.1.1.1, but always through the default route next-hop. Everything works normal after rebooted the router. Suppose it should caused by a bug? BTW, my Cisco7609 is runing BGP with ISP which received about 10K routes.
what the upgrade path is for 5505 ASA . I have one which is version 7.2 and need to upgrade it to 8.4(5). I have read that it needs to upgraded btwn major release versions.Not sure if I need to upgrade from 7.2 - 8.0 , then form 8.0 - 8.2, then from 8.2 - 8.3 and finally 8.3 to 8.4 or can I just upgrade from 7.2 - 8.2 and then from 8.2 - 8.4 .Also what is the minimum memory requirements for vers 8.4 .my ASA running on vers 7.2 currently has 256Mb Memory and I will be upgrading this to 512MB before I do the upgrade the image above?
I run a home private server on Centos 5.5 I believe. A while ago, a surge destroyed a different computer with pictures on it that my parents would like to access. The hard drive itself is just fine, and I've backed up those files on an external hard drive. What I would like to do is allow my parents to access them through Samba. Samba has already been in long time use, but it is configured to only allow access in a jail inside each user's home folder on the root hard drive. I have a suitable hard drive already formatted and mounted that can fit all the pictures that they wish to have access too. What I'd like to do, is change the path that one of my users use to the mounted hard drive.
I am running a Windows 7 Professional 32 bit as my office computer. About 3 PCs in the office are connected to the office server through wireless connection (including mine), and another 3 are connected through a wired connection. My connection to the server doesn't work at times. I get an error message that "An error occurred while connecting to . The network path was not found." The other PCs using the network have no problem connecting to the server. Also, the internet connection is shared from the server and I have no trouble with it. The problem is only with accessing the shared folder on the server.
I've got a windows server 2003 running a big application (sage1000) but suddenly it seems that users cannot access the server by unc path.i've also test to access \server on the server itself doesen't work.
I'm trying to troubleshoot a problem with mpls fast reroute. The primary (protected) link is between PE-PE and the backup link is PE-P-PE. The IGP I'm using is OSPF. When there is a issue with the primary link and debug mpls tra tunnels signalling there is a message "LSP-TUNNEL-SIG: TunnelX [237]: re-route path verification failed (protected) [Can't use link x.x.x.x on node x.x.x.x]". After 30 seconds (without ospf tuning) the SPF is recalcalated, but that's not the point From the show mpls tra tunnels tu1013 (the backup one)everything looks ok:
Status:Admin: up Oper: up Path: valid Signalling: connected From show mpls tra fast-reroute database everything is ok, the status is Ready I'm using 7206VXR, Version 12.4(24)T3
I have a Cisco router 877. I am trying to configure a backup with ISDN.The primary line is an ADSL over pppoe. The problem is that despite the primary line fails, doesn't change the path and continue going by the main route.I have a very similar setup, also with a cisco 877, but with a normal DSL and it works perfectly.I solved the problem by activating a tracking but is slower than the other method.
