Can anyone tell me if there is an equivalent CLI command to reset an interface configuration to default? In IOS it is "default interface <interface>" which removes all configuration from that switch port. I don't seem to be able to find the same in the SG series CLI. Thanks, Rob

Hi Chris, I just came across this issue on my own workstation. IP Communicator was working fine on Friday but this morning it crashed when I answered a call and then would not re-launch, it just came up with a black screen. I completely uninstalled it, including deleting the folder: C:\Program Files (x86)\Cisco Systems\Cisco IP Communicator\ (your drive letter may vary...) I then reinstalled the same version (8.6.1) and it is now working again. I hope this helps. Rob

Any time I have seen the "Auth Fail" message is due to the wrong phone model being selected in CUCM. I have a mix of phones and sometimes clone the wrong model, this will cause the Auth Fail message.

Hello, We have an ASA for our IPSec VPN service that has been up and running for some time. We ran into an issue at a trade show this week in which we could connect to our VPN using the trade show wifi but could not access anything behind our firewall (computers, servers, etc.) yet simply tethered to a cell phone, and using the VPN we could then access what we needed. I suspect some sort of conflict with the local trade show wifi subnet and our internal subnet behind the firewall, although both connections are using NAT. The trade show DHCP is handing out 172.16.0.0/16 addresses and the subnet we're trying to access behind the VPN is 172.16.128.0/22. VPN connections are assigned addresses from a separate pool (10.4.99.0/24). When using the wifi and VPN I am able to connect, and ping the gateway interface of the ASA, but nothing beyond. When using cellular and VPN I am able to ping the gateway and pass traffic to services behind it. Any thoughts on how this might be resolved? We have not run into this before and the VPN has been in use for several years. Thanks, Rob

That has helped a bit, it seems there are fewer of those messages but there are still quite a few EAP session timed out being recorded.

I've got ACS currently authenticating wireless users - using EAP-MSCHAPv2. There are a large number of failures being reported as: 5411 EAP session timed out Description This may be due to EAP misconfiguration on ACS or Network Device. Resolution Steps Please contact TAC. However there does not appear to be any impact to the users as they appear to be authenticating normally shortly after any of these errors. At this point it's more of an inconvenience but I'd like to see if I can't resolve the issue. The error says to contact TAC but we don't have a support contract for ACS at this time. Any help is appreciated.

Thanks Tarik, I had considered using that method and tweaking the timers but this was a recommended alternative in some of the Cisco white papers. I'll certainly try it out. I am running 5.3.0.40.6 in VMware. Current port config is as follows: interface FastEthernet0/14 description 802.1X Test Port switchport mode access switchport block unicast switchport voice vlan 100 srr-queue bandwidth share 10 10 60 20 priority-queue out authentication event fail action next-method authentication host-mode multi-auth authentication order mab dot1x authentication priority dot1x mab authentication port-control auto authentication violation restrict mab mls qos trust device cisco-phone mls qos trust cos dot1x pae authenticator auto qos voip cisco-phone spanning-tree portfast spanning-tree bpduguard enable service-policy input AutoQoS-Police-CiscoPhone The switch is a 2960 with 12.2(50)SE1 Lan Base

Hello, We are in the process if deploying ACS for several scenarios. It will be taking over from Microsoft's built in NPS for wireless authentication as well as providing authentication for VPN users and ultimately wired 802.1x services as well. With respect to the wired access - I've attended a number of sessions at Cisco Live over the past couple of years regarding 802.1x deployment and the initial "monitor mode" to prevent impact to users. I'm currently configuring a very basic set of rules for the wired deployment and testing. I've run into some issue with client's connecting behind VoIP phones. I have a fairly basic set of Service Selection Rules matching on the NAS-Port-Type. One for Ethernet and one for IEEE-802.11. From there I have two Access Services configured. The Wireless policy is working and does not appear to have any issues. It is using Active Directory and authorizing against AD group memberships. The Wired policy has two rules, the first matching Auth-method for Lookup and uses the Internal Hosts, the second for MSCHAPv2 which uses Active Directory. The idea being when mab-auth fails for an 801.x capable client behind a Cisco phone, the next rule in place then authenticates against AD. I have set the "continue" action for a failed host lookup but it doesn't appear to work: Logged At: August 30,2012 11:59:26.213 AM RADIUS Status: Authentication failed : 15039 Selected Authorization Profile is DenyAccess NAS Failure: Username: 00-15-C5-86-07-D4 MAC/IP Address: 00-15-C5-86-07-D4 Network Device: Test Switch : 172.16.128.35 : FastEthernet0/14 Access Service: Domain Wired Identity Store: Authorization Profiles: DenyAccess CTS Security Group: Authentication Method: Lookup Then the second auth request is a success: Logged At: August 30,2012 11:59:26.873 AM RADIUS Status: Authentication succeeded NAS Failure: Username: host/Facemelter7.ssd.local MAC/IP Address: 00-15-C5-86-07-D4 Network Device: Test Switch : 172.16.128.35 : FastEthernet0/14 Access Service: Domain Wired Identity Store: AD1 Authorization Profiles: Permit Access CTS Security Group: Authentication Method: PEAP(EAP-MSCHAPv2) As you can see the failure and then success are about 5 tenths of a second apart so there's no impact really. But my question is this: Is this a good way to structure the rules? Every client behind a phone records an auth-failure and then an auth-success in ACS, so it gives the appearance of a lot of failures. Is there a better way to do MAB? Thanks! Rob

It looks like DHCP is working for controller discovery but the controller or AP is failing the config process. There should be a log on the controller as well, does it provide any more details? Sent from Cisco Technical Support iPhone App

Hi Chandra, Switching to using DNS for discovery became a much better solution for us overall as we have now also mixed in some AP's from another vendor (Ruckus) and they also use a DNS discovery. From this guide: http://www.cisco.com/en/US/docs/wireless/controller/5.2/configuration/guide/Controller52CG.html "DNS discovery—The access point can discover controllers through your domain name server (DNS). For the access point to do so, you must configure your DNS to return controller IP addresses in response to CISCO-LWAPP-CONTROLLER.localdomain, where localdomain is the access point domain name. When an access point receives an IP address and DNS information from a DHCP server, it contacts the DNS to resolve CISCO-LWAPP-CONTROLLER.localdomain. When the DNS sends a list of controller IP addresses, the access point sends discovery requests to the controllers. " This example uses LWAPP but it's the same for CAPWAP. All you need to do is add an A record to your domain DNS server for "cisco-capwap-controller.localdomain" (using whatever your local domain actually is) and the AP's will use this for discovery. We also added an A record for "zonedirector.localdomain" which the Ruckus AP's use for discovery so regardless of which AP's we use where, they always contact the correct controller. I hope this helps! Rob

Ok I assumed that if I changed the default firmware in CUCM the default load would reflect that. I guess not. Interestingly enough it seems this is a known bug because the 8.5.2 firmware is the only version that doesn't require a service contract to download. So I downloaded the package, and unzipped all of the files including the term62.default.loads into my tftp folder and fired up Tftpd32. Rebooted the phone and bingo, the phone started requesting the files. It still had a blank screen mind you, which was unnerving but it reset itself after the download and the wonderful Cisco splash screen appeared once again. I re-adjusted my option 150 to point back at the CUCM tftp server and the phone happily upgraded itself to 8-5-2S and is back up and running. That's a slick fix I'm going to have to remember. Stars all around.
