tried to run the easy setup assistant but failed the connection test. The WLAN indicator did not flash or light up, don't know if that is the problem.
Have checked the cables and they are working fine. As this router is 3 yrs old, should I get a new one? Does it appear to be a hardware problem?
We have two Cisco 2960 TT-L switches. I'd like to reduce single points of failure and have dual servers for most tasks. For example, two firewall servers and two web servers. Should one server fail the other will act as a failover.I'd like to extend the redundancy to the switches, and am thinking of connecting one web server to one switch, and one to the other. In the event a switch failed a set of servers would still run, and be able to talk to each other.I'd like to run two VLANs, one for the LAN, and one of the WAN, and connect the two VLANs on each of the switches with the associated VLAN on the other switch.

I have a lab network setup at my house with similar equipment to our office that I use for testing different features and functionality. Since I have had this installed (~ 2 years) I've had an intermittent but recurring problem with connectivity to various wireless devices that I have never been able to fully resolve.I have a 5508 Wireless controller with a handful of 3502i APs spread throughout my house. The controller is connected to a 3560X switch. And I have an ASA 5510 firewall as my Firewall/Internet Gateway. When I work from home I most often work from a desktop computer in my office and have a Windows RDP session to a laptop located in another room in my house on one of my monitors as a working space (I know this is weird but there is a good reason). This laptop is connected via WiFi at all times.Occasionally, I will lose connectivity to this laptop (or not be able to connect back to my desktop from it) and have to start an extended ping from the laptop to the desktop to re-establish connectivity. A while ago I performed some deeper analysis on what was happening and what I found is that when the connectivity breaks the problem is that the desktop is unable to resolve the MAC address of the laptop. It sends out ARP requests but never receives any reply back.
Why would the controller stop replying to ARP requests for the IP address of the laptop?If I log into the controller while this is happening it shows the laptop as a connected client, and has its IP address and MAC address listed fine in the clients section. In order to avoid getting up every time I need to reconnect, I normally hop to a system I control across one of my VPN tunnels via RDP, then connect BACK to the laptop and start the ping to re-establish connectivity back to my main desktop machine. This works because the firewalls ARP cache hasn't cleared yet. And then everything works fine again... unless I manually clear my ARP cache. Sometimes clearing the ARP cache will result in the exact same problem again and I will lose connection. Other times it seems to repopulate almost immediately and the connection doesn't drop.
A wireshark debug from the desktop reveals that ARP requests simply go out with no reply, confirming what is happening.As a note, I have set both the User Idle Timeout and the ARP timeout to 24 hours to try but this has not had any effect.This problem seems to go away and then come back. In fact, I havent been experiencing this issue for probably a couple months recently and then it just started again in the last few days which is why I am back to posting here. No changes to the network were made in the meantime that could account for this change in behavior. I am currently running version 7.2.111.3 but this behavior has persisted through at least four software upgrades so I don't think it's an issue with a specific version but I don't really know.I occasionally epxerience connectivity issues in my house to other devices as well that I use less often like a printer, network camera, apple tv so I now feel like these issues are likely all related.

View 9 Replies View Relatedfor some reason some AP's are terminating the association to either one of the controllers for a short period of time. When this happens and the AP re-associates itself with either of the active controllers, it looses the information of what group it previously belonged; and it gets dropped in the default group, broadcasting every single SSID available.
What I would like to see happen is that if for some reason an AP terminates association, but restablishes it shortly; it can automatically go to the correct group.
Both WLC are running the same version and have the same amount of licenses, they can hold all the AP's one of the WLC came down. Config-wise they are identical except that the groups are named differently but ultimately configured the same. If that is an issue we can change it no problem since it's only the name.
We have found that only Cisco 1231 WAP are exhibiting this behaviour. Their Primary WLAN controller is Cisco1 WLC but they fail to register to Primary WLC and fall back to Cisco2 WLC. After about 200 sec , they attempt to connect to Primary WLC once again and fail. The whole cycle is repeated every 250 seconds.
View 3 Replies View RelatedI have a point to point link of 9.27 km using 1410 bridges and AIR-ANT58G28SDA-N antennas as per the documentation that would be an easy to deploy link and it should work at 54 Mbps, eventhough it drops the link, it's so slow and the power measurments indicate -70 dbm (aprox) right under the antenna which is at 9 m height.
This is not the first time I have troubles with 1410 bridges, the other two times I had to change them for 1310 bridges. I wonder if it has to do with some configuration tunning like, external antena gain, link distance or anything else? By the wat this is ocurring in México don't know if that might be worth of taking into consideration in order to deploy a 1410 link.

View 9 Replies View RelatedI have a problem where wireless clients at a remote site cannot successfully authenticate through their WLC to my ACS 5.2 (Linux on VM). I have three sites where this authentication is functioning properly; at my fourth site the wireless clients fail with a PEAP error: "12321 PEAP failed SSL/TLS handshake because the client rejected the ACS local-certificate". My wireless clients are Win7 using WPA2-Enterprise security type with AES encryption. The authentication method is set to Microsoft PEAP (EAP-MSCHAP v2) and the 'Validate server certificate' is not checked. My wireless access rules on ACS 5.2 are working well at three sites. My ACS 5.2 has a self-signed certificate that doesn't expire until August 2012. A laptop that can successfully authenticate at other sites cannot authenticate at the fourth site.
Phase one of the PEAP process is where the client authenticates the server certificate and the TLS tunnel is created so that in phase two user authentication credentials are sent through the TLS tunnel using EAP. My clients do not seem to be able to create the TLS tunnel because they reject the ACS local certificate; thus, user credentials are never passed and authentication fails. I have renewed the ACS local certificate and rebooted the ACS server but the problem persists. My WLAN on the WLC has its security policy set to [WPA + WPA2][Auth(802.1X)]. WPA uses TKIP and WPA2 uses AES; Auth Key Mgmt is set to 802.1X. The remote site where authentication fails is a different domain; the other three sites are the same domain.
I can see the failed authentication attempts in my ACS "Monitoring and Reports | Reports | Catalog | AAA Protocol | RADIUS Authentication" report. They all fail with the same PEAP error: 12321 PEAP failed SSL/TLS handshake because the client rejected the ACS local-certificate. The ACS local certificate works fine at three sites--just not at the fourth. Is my problem the certificate or is it an 802.1X client problem?

View 1 Replies View RelatedI have three 5508 WLCs, running code 7.0.98.0 supporting 100+ LWAPs in H-REAP mode. The LWAPs are servicing 2-3 WLANs each. Some are using central authentication and local switching, some are configured for central authentication and central switching. When the LWAPs fail from one WLC to another WLC, the LWAP's lose all of their VLAN mappings and pick up the VLAN of the management interface on the new WLC.
All WLANs are configured to use the management interface on the WLC and the VLAN mappings are configured per LWAP on the H-REAP properties tab. The WLAN ID numbers and all the WLAN settings are the same across all 3 WLC's. I have created AP groups on all 3 WLC's and the AP group config matches across the 3 WLCs.
I can get the LWAPs to keep their VLAN mapping by creating an interface on the WLC with the VLAN ID of the locally switched/remote site VLAN and then setting the interface for the WLAN to the new interface. However, then the WLAN doesn't work, because the centrally located WLC doesn't have the remote site VLAN. It also seems to keep the VLAN mapping if I create the locally switched/remote site VLAN interface on the WLC , and point the WLAN to the management interface. This shouldn't be a necessary step though... In H-REAP with local switching, the LWAPs aren't using the interface on the WLC.
I found a note in the 7.0 WLC config guide that explains why the VLANs are picking up the management interface VLAN, but that same note says the VLAN mappings can be changed per LWAP/WLAN!
From config guide: For hybrid-REAP access points, the interface mapping at the controller for WLANs that is configured for H-REAP Local Switching is inherited at the access point as the default VLAN tagging. This mapping can be easily changed per SSID, per hybrid-REAP access point
Using H-REAP and been able to get the LWAPs to keep the VLAN mapping when failing from one WLC to another?
We have two ASA 5500 series Firewalls running 8.4(1). One in New York, another in Atlanta.They are configured identically for simple IPSecV1 remote access for clients. Authentication is performed by an Radius server local to each site.
There are multiple IPSec Site-to-Site tunnels on these ASA's as well but those are not affected by the issues we're having.First, let me start with the famous last words, NOTHING WAS CHANGED.
All of a sudden, we were getting reports of remote users to the Atlanta ASA timing out when trying to bring up the tunnel. They would get prompted for their ID/Password, then nothing until it times out.Sames users going to the NY ASA are fine.After extensive troubleshooting, here is what I've discovered. Remote clients will authenticate fine to the Atlanta Firewall ONLY IF THEY ARE USING A WIRED CONNECTION.
If they are using the wireless adapter for their client machine, they will get stuck trying to login to Atlanta.These same clients will get into the New York ASA with no problems using wired or wireless connections.Windows 7 clients use the Shrewsoft VPN client and Mac clients use the Cisco VPN client. They BOTH BEHAVE the same way and fail to connect to the Atlanta ASA if they use their wireless adapter to initiate the connection.
Using myself as an example.
1. On my home Win 7 laptop using wireless, I can connect to the NY ASA with no issues.
2. The same creditials USED to work for Atlanta as well but have now stopped working. I get stuck until it times out.
3. I run a wire from my laptop to the FiOS router, then try again using the same credentials to Atlanta and I get RIGHT IN.
This makes absolutely no sense to me. Why would the far end of the cloud care if I have a wired or wireless network adapter? I should just be an IP address right? Again, this is beyond my scope of knowledge.We've rebuilt and moved the Radius server to another host in Atlanta in our attempts to troubleshoot to no avail. We've also rebooted the Atlanta Firewall and nothing changed.
We've tried all sorts of remote client combinations. Wireless Internet access points from different carriers (Clear, Verizon, Sprint) all exhibit the same behavior. Once I plug the laptops into a wired connection, BAM, they work connecting to Atlanta. The New York ASA is fine for wired and wireless connections. Same with some other remote office locations that we have.
Below I've detailed the syslog sequence on the Atlanta ASA for both a working wired remote connection and a failed wireless connection. At first we thought the AAA/Radius server was rejecting us but is shows the same reject message for the working connection. Again, both MAC and Windows clients show the same sequence.Where the connection fails is the "IKE Phase 1" process.
